However, for people with disabilities, even a small threshold height can unfortunately be an insurmountable obstacle. Therefore, if the shower is intended for use by a person with reduced mobility, the height of the entrance threshold should be kept to a minimum. As a result, the height of the receiver and means of evacuation of water from the shower tray must in this case be reduced to the minimum possible, which amplifies even more the problem related to the evacuation of wastewater.

Description

L'invention concerne le domaine des installations de douche et en particulier un procédé de remplacement d'une baignoire existante par une douche. L'invention porte sur un procédé de remplacement d'une baignoire existante par une douche, et sur l'installation de douche utilisé pour la mise en oeuvre d'un tel procédé.The invention relates to the field of shower facilities and in particular a method of replacing an existing bath with a shower. The invention relates to a method of replacing an existing bath with a shower, and the shower installation used for the implementation of such a method.

De nos jours, il arrive souvent, entre autre par soucis d'économiser l'eau potable, que l'on désire remplacer une baignoire existante par une douche. Un tel remplacement peut aussi se justifier par le fait que, globalement, les progrès en matière de santé sont tels qu'on assiste à un vieillissement progressif de la population qui aboutit à un nombre toujours croissant de personnes âgées parmi lesquelles de plus en plus souffrent d'un problème de mobilité réduite. Il existe aussi des personnes, pas forcément âgées, qui doivent vivre, à la suite d'un accident ou même depuis la naissance, avec un problème de mobilité réduite. Pour ces personnes, entrer et sortir d'une baignoire implique des mouvements qui peuvent s'avérer difficiles et même parfois impossibles et, dans le logement de ces personnes, il s'avère donc souvent nécessaire que la baignoire soit, à un moment donné, remplacée par une douche.Nowadays, it often happens, among other things to save drinking water, that you want to replace an existing bath with a shower. Such a replacement may also be justified by the fact that, overall, progress in health is such that there is a gradual aging of the population which leads to an ever increasing number of elderly people, of whom more and more are suffering. a reduced mobility problem. There are also people, not necessarily elderly, who must live, as a result of an accident or even since birth, with a mobility problem. For these people, entering and leaving a bathtub involves movements that can be difficult and sometimes impossible and, in the housing of these people, it is therefore often necessary that the bath is, at a given time, replaced by a shower.

Or, depuis toujours, lorsque l'on désire remplacer une baignoire existante par une douche, il se pose de nombreux problèmes. Tout d'abord, lors de l'extraction de la baignoire existante, bien souvent, les murs de la salle de bain qui étaient précédemment cachés par la baignoire n'ont pas le même niveau de finition que le reste des murs de la salle de bain. De ce fait, en général, si l'on veut remplacer une baignoire par une douche, il est souvent nécessaire de carreler ou peindre la partie des murs mise à nu lors de l'extraction de l'ancienne baignoire.But always, when you want to replace an existing bathtub with a shower, there are many problems. First of all, when removing the existing bathtub, the bathroom walls that were previously hidden by the bathtub often do not have the same level of finish as the rest of the walls in the bathroom. bath. Therefore, in general, if you want to replace a bathtub with a shower, it is often necessary to tile or paint the exposed part of the walls when removing the old bathtub.

Ensuite, il est bien souvent nécessaire de maçonner le sol de la salle de bain à l'emplacement laissé vacant lors de l'extraction de la baignoire d'origine afin que cet emplacement puisse recevoir la nouvelle installation de douche et, généralement, c'est ensuite la mise en place les robinets et autres accessoires qui est nécessaire puis le raccordement des moyens d'évacuation d'eau de la salle de bain aux moyens d'évacuation d'eau de la douche. Finalement, bien souvent, c'est enfin le montage des moyens destinés à la fermeture de la douche qui clôture le processus de remplacement de la baignoire.Then, it is often necessary to lay the floor of the bathroom in the vacant place when the original bathtub is removed so that this location can accommodate the new shower facility and usually is then the setting up the faucets and other accessories that is necessary then the connection of the means of evacuation of water from the bathroom to the means of evacuation of water from the shower. Finally, often, it is finally the assembly of the means for closing the shower that closes the process of replacing the bathtub.

L'intervention des différents corps de métier nécessaire pour l'accomplissement de ces différentes tâches induit des travaux de rénovation qui doivent nécessairement s'étaler sur plusieurs jours, une organisation des tâches compliquée et des coûts de main d'oeuvre importants. La nature des travaux entraine généralement une durée d'intervention plus longue.The intervention of the various trades necessary for the accomplishment of these various tasks induces renovation works which must necessarily be spread over several days, a complicated organization of tasks and significant labor costs. The nature of the work generally entails a longer duration of intervention.

De plus, lorsque les travaux de rénovation sont entrepris, il se pose par ailleurs d'autres problèmes.In addition, when renovations are undertaken, there are other problems.

Tout d'abord, les baignoires généralement vendues dans le commerce peuvent être de différentes tailles. En effet, les baignoires standards ont souvent une hauteur comprise entre 58 cm et 75 cm, une longueur comprise entre 130 cm et 185 cm et une largeur comprise entre 70 cm et 85 cm. Par conséquent, le bac de douche de remplacement doit être adaptable aux différentes tailles standards de baignoire sans pour autant nécessiter de lourds travaux d'adaptation. Par ailleurs, les dimensions du bac de douche doivent aussi être telles qu'on puisse le faire entrer par n'importe quelle porte de taille standard, dont la largeur commune en Europe est souvent inférieure à 85 cm.First of all, bathtubs generally sold in commerce can be of different sizes. Indeed, standard baths often have a height between 58 cm and 75 cm, a length between 130 cm and 185 cm and a width between 70 cm and 85 cm. Therefore, the replacement shower tray must be adaptable to different standard bath sizes without the need for heavy adaptation work. Moreover, the dimensions of shower tray must also be such that it can be entered by any door of standard size, whose common width in Europe is often less than 85 cm.

Un autre problème qui se pose est lié à l'évacuation des eaux usées. En effet, lors du processus de rénovation d'une salle de bain, et en particulier lors du remplacement d'une baignoire existante par une douche, les contraintes sont, entre autre, fixées par le système d'évacuation des eaux usées existant. Il convient en effet, une fois la baignoire existante extraite, de raccorder les moyens d'évacuation d'eau du nouveau bac de douche aux moyens d'évacuation d'eau présents dans la salle de bain. Cependant, les moyens d'évacuation en eau d'une baignoire comprennent en général un siphon qui se trouve à une certaine hauteur du sol et, par conséquent, le nouveau bac de douche devra normalement être fixé à une certaine hauteur du sol.Another problem that arises is the disposal of wastewater. Indeed, during the renovation process of a bathroom, and especially when replacing an existing bath with a shower, the constraints are, among other things, fixed by the existing sewage system. It is appropriate, once the existing bathtub extracted, to connect the water evacuation means of the new shower tray to the water evacuation means present in the bathroom. However, the water evacuation means of a bath generally include a siphon which is at a certain height of the ground and, therefore, the new shower tray will normally have to be fixed at a certain height of the ground.

Le problème qui peut se poser, si l'on souhaite diminuer voire éliminer le seuil du bac, vient donc du fait que les moyens d'évacuation d'eau d'un bac de douche sont à un niveau beaucoup plus bas que le niveau du siphon ce qui interdit, dans ce cas, une évacuation directe des eaux usées.The problem that may arise, if it is desired to reduce or even eliminate the threshold of the tank, is therefore that the means for discharging water from a shower tray are at a level much lower than the level of the tank. siphon which prohibits, in this case, a direct evacuation of wastewater.

De plus, dans les logements collectifs par exemple, il est en général impossible, lors du raccordement des moyens d'évacuation en eau du bac de remplacement, de faire transiter les tuyaux d'évacuation d'eau sous le plancher afin de rejoindre un point d'évacuation d'eau situé à un niveau plus bas que celui du bac de douche et permettre ainsi une évacuation directe des eaux usées. Dans ce type de logements, lorsque l'on désire remplacer une baignoire existante par une douche, les contraintes sont donc fixées par le système d'évacuation des eaux existant et par la marge de manoeuvre limitée en ce qui concerne les travaux d'adaptation.Moreover, in collective dwellings for example, it is generally impossible, when connecting the water evacuation means of the replacement tank, to pass the water evacuation pipes under the floor to reach a point water drain located at a lower level than that of the shower tray and thus allow direct evacuation of wastewater. In this type of housing, when it is desired to replace an existing bath with a shower, the constraints are therefore fixed by the existing drainage system and by the limited room for maneuver with regard to the adaptation work.

Ce problème lié à l'évacuation des eaux usées se pose par ailleurs d'autant plus lorsque la douche est destinée à être utilisée par une personne à mobilité réduite. En effet, pour ces personnes, c'est non seulement entrer et sortir d'une baignoire qui est difficile mais, bien souvent, même entrer et sortir d'une douche peut se révéler une tâche laborieuse voire impossible. En effet, à cause entre autre des problèmes liés à l'évacuation des eaux usés, les bacs de douche traditionnels comprennent souvent un seuil d'entrée dont la hauteur est en général supérieure à 15 centimètres, ceci afin de pouvoir adapter en dessous du bac un siphon. Cependant, pour les personnes souffrant d'un handicap, même une faible hauteur de seuil peut malheureusement représenter un obstacle insurmontable. Par conséquent, si la douche est destinée à être utilisée par une personne à mobilité réduite, il faut limiter au maximum la hauteur du seuil d'entrée. En conséquence, la hauteur du receveur et des moyens d'évacuation d'eau du bac de douche doivent dans ce cas être ramenés au minimum possible, ce qui amplifie d'autant plus le problème lié à l'évacuation des eaux usées.This problem related to the evacuation of wastewater is also more relevant when the shower is intended to be used by a person with reduced mobility. Indeed, for these people, it is not only entering and leaving a bathtub that is difficult but, often, even getting in and out of a shower can be a laborious or impossible task. Indeed, because of the problems related to the evacuation of wastewater, the traditional shower trays often include an entry threshold whose height is generally greater than 15 centimeters, in order to adapt below the tray. a siphon. However, for people with disabilities, even a small threshold height can unfortunately be an insurmountable obstacle. Therefore, if the shower is intended for use by a person with reduced mobility, the height of the entrance threshold should be kept to a minimum. As a result, the height of the receiver and means of evacuation of water from the shower tray must in this case be reduced to the minimum possible, which amplifies even more the problem related to the evacuation of wastewater.

Le document WO 2008/137554 A2 décrit un procédé de montage d'une baignoire vue comme une douche comprenant une étape consistant à installer une structure monobloc de bac de douche, le bac comprenant trois parois latérales, un receveur, une corniche horizontale s'étendant vers l'extérieur de l'extrémité supérieure des trois parois latérales et une corniche frontale horizontale formant le pas de la porte le long de la partie antérieure du bac située à la hauteur de l'extrémité supérieure du receveur, une étape consistant à raccorder des premiers moyens d'évacuation d'eau présents sur ladite structure aux moyens d'évacuation d'eau existants dans la salle de bain et une étape consistant en la mise en place de la structure en utilisant des moyens de support réglables en hauteur. Le document WO 2008/137554 A2 divulgue aussi une installation de douche qui comprend un bac de douche comprenant une structure monobloc comprenant trois parois latérales avec un receveur, une corniche horizontale s'étendant vers l'extérieur de l'extrémité supérieure des trois parois latérales et une corniche frontale horizontale formant le pas de la porte le long de la partie antérieure du bac située à la hauteur de l'extrémité supérieure du receveur, des moyens de support du bac réglables en hauteur, des moyens d'alimentation en eau et des moyens d'évacuation d'eau. Divers autres documents de l'état de la technique renseignent sur des procédés de remplacement d'une baignoire existante par une douche.The document WO 2008/137554 A2 discloses a method of mounting a bathtub as a shower comprising a step of installing a monobloc structure of shower tray, the tray comprising three side walls, a receiver, a horizontal cornice extending outwardly of the upper end of the three side walls and a horizontal frontal cornice forming the pitch of the door along the front portion of the tray located at the height of the upper end of the receiver, a step of connecting first discharge means of water present on said structure to the existing water evacuation means in the bathroom and a step consisting in the establishment of the structure using support means adjustable in height. The document WO 2008/137554 A2 also discloses a shower installation which comprises a shower pan comprising a one-piece structure comprising three side walls with a receiver, a horizontal cornice extending outwardly from the upper end of the three side walls and a horizontal frontal cornice forming the not the door along the front portion of the tray located at the height of the upper end of the tray, means for supporting the tray adjustable in height, water supply means and means for discharging water. Various other documents of the state of the art provide information on methods of replacing an existing bath with a shower.

Une première solution décrite dans le document EP 1 961 353 consiste à casser le support de la baignoire existante et à faire usage des débris comme socle du bac de douche de remplacement. Afin d'aplanir et présenter une surface homogène, une mousse est ensuite utilisée pour combler le vide laissé entre les débris. Cette solution présente le désavantage que les murs de la salle de bain, aux endroits où la baignoire d'origine était présente, doivent être habillés d'une feuille de couverture ce qui nécessite un temps de rénovation plus long et des coûts plus élevés. De plus, la solution proposée ne résout pas le problème lié à l'évacuation des eaux usées et ne garantit pas une hauteur de seuil permettant à une personne à mobilité réduite d'entrer dans la douche sans problème.A first solution described in the document EP 1 961 353 involves breaking the existing bath support and using debris as the base of the replacement shower tray. In order to smooth out and present a homogeneous surface, a foam is then used to fill the gap left between debris. This solution has the disadvantage that the walls of the bathroom, where the bathtub original was present, must be dressed with a cover sheet which requires a longer renovation time and higher costs. In addition, the proposed solution does not solve the problem related to the evacuation of wastewater and does not guarantee a height of threshold allowing a person with reduced mobility to enter the shower without problem.

Une autre solution proposée dans le document FR 2 882 243 consiste en une installation comprenant un receveur encastrable et plusieurs panneaux muraux fixés sur le receveur. Cependant, cette solution ne résout pas le problème lié à l'évacuation des eaux usées et ne garantit pas non plus une hauteur de seuil limitée.Another solution proposed in the document FR 2 882 243 consists of an installation comprising a built-in shower tray and several wall panels fixed to the shower tray. However, this solution does not solve the problem related to the evacuation of wastewater nor does it guarantee a limited threshold height.

Une troisième solution proposée dans FR 2 905 958 consiste à faire usage d'une pompe pour véhiculer les eaux usées depuis les moyens d'évacuation du bac de douche jusqu'au siphon d'évacuation de la salle de bain. Le dispositif décrit dans FR 2 905 958 ne permet cependant pas de couvrir les parties du mur mises à jour lors de l'extraction de la baignoire existante. L'intervention d'un peintre ou d'un carreleur est donc nécessaire, ce qui implique un temps de rénovation plus long et des coûts plus élevés. De plus, dans le cadre d'une rénovation de salle de bain, le sol mis au jour lors de l'extraction de la baignoire existante devra être adapté par un maçon.A third solution proposed in FR 2 905 958 is to use a pump to convey the wastewater from the means of evacuation of the shower tray to the siphon of evacuation of the bathroom. The device described in FR 2 905 958 However, it does not cover the parts of the wall that are updated when the existing bathtub is removed. The intervention of a painter or a tiler is necessary, which implies a longer renovation time and higher costs. In addition, as part of a bathroom renovation, the floor uncovered during the extraction of the existing bathtub must be adapted by a mason.

Aucun des systèmes de l'art antérieur ne permet donc de remplacer une baignoire existante par une douche dans un temps minimum et sans avoir à faire intervenir plusieurs corps de métier. De plus, aucun des systèmes connus ne propose un bac de douche muni de moyens permettant un raccordement simple des moyens d'évacuation en eau du bac à ceux de la salle de bain tout en conservant une hauteur de seuil permettant à une personne à mobilité réduite d'entrer et sortir de la douche.None of the systems of the prior art therefore allows to replace an existing bath with a shower in a minimum time and without having to involve several trades. In addition, none of the known systems proposes a shower tray provided with means for a simple connection of the water evacuation means of the tray to those of the bathroom while maintaining a threshold height for a person with reduced mobility to come in and out of the shower.

Le but de l'invention est donc de proposer un procédé de remplacement d'une baignoire existante par une douche qui ne requiert pas l'intervention de différents corps de métier et qui permette le remplacement de la baignoire dans un temps et pour des coûts limités. L'invention a aussi pour objet de ramener le processus de rénovation à une opération extrêmement rapide et pouvant être mené par une personne seule. Le procédé selon l'invention permet de remplacer une baignoire existante par une douche dans un temps minimum tout en offrant aussi la possibilité pour que des personnes à mobilité réduite puissent accéder à la douche sans problème.The object of the invention is therefore to provide a method of replacing an existing bath with a shower that does not require the intervention of different trades and allows the replacement of the bath in a time and for limited costs . The invention also aims to reduce the renovation process to an extremely fast operation and can be conducted by a single person. The method of the invention allows to replace an existing bath with a shower in a minimum time while also offering the possibility for people with reduced mobility can access the shower without problem.

La figure 1 représente la salle de bain après extraction de la baignoire existante. L'emplacement 11 réservé à la baignoire se situe entre trois murs et la partie des murs mise à nu 12 n'est pas du même niveau de finition que le reste des murs de la salle de bain. Par ailleurs, à l'emplacement de la baignoire d'origine, le sol 13 de la salle de bain n'est pas non plus du même niveau de finition que le reste du sol de la salle de bain. L'emplacement 11 représenté à la figure 1 se situe entre trois murs de la salle de bain mais il est aussi possible qu'un ou plusieurs de ces murs soient de simples panneaux entourant la baignoire.The figure 1 represents the bathroom after extraction of the existing bathtub. The location 11 reserved for the bath is between three walls and the part of the walls exposed is not the same level of finish that the rest of the bathroom walls. Moreover, at the location of the original bathtub, the floor 13 of the bathroom is also not the same level of finish as the rest of the floor of the bathroom. Location 11 represented at figure 1 is between three walls of the bathroom but it is also possible that one or more of these walls are simple panels surrounding the bathtub.

La figure 2 représente la salle de bain après mise en place du bac de douche de remplacement. Comme on le voit, l'installation de douche selon l'invention permet de couvrir les parties des murs de la salle de bain mises à nu lors de l'extraction de la baignoire.The figure 2 represents the bathroom after installation of the replacement shower tray. As can be seen, the shower installation according to the invention makes it possible to cover the parts of the walls of the bathroom exposed during the extraction of the bath.

L'installation de douche comprend un bac de douche 21 constitué d'une structure monobloc comprenant trois parois latérales 22, 23, 24, un receveur 25, une corniche horizontale 26 s'étendant vers l'extérieur de l'extrémité supérieure des trois parois latérales et une corniche frontale horizontale 27 tout le long de la partie antérieure du bac située à la hauteur de l'extrémité supérieure du receveur 25. Le bac de douche comprend en outre une bonde 28 destinée à l'évacuation des eaux usées. La bonde 28 peut être un modèle de bonde standard mais peut aussi être spécifique, par exemple une bonde siphoïde qui peut avantageusement être moulée en usine au sein de la structure monobloc. Par ailleurs, le bac de douche comprend un couvercle 30 servant à cacher le vide existant en dessous du bac de douche et les moyens de support 32 réglables en hauteur installés sous le bac, derrière la corniche frontale 27. Comme il est décrit en détail en rapport avec les figures 5a-5c, ce couvercle peut, le cas échéant, être supprimé.The shower installation comprises a shower tray 21 consisting of a one-piece structure comprising three side walls 22, 23, 24, a receiver 25, a horizontal cornice 26 extending outwardly from the upper end of the three walls. side and a horizontal frontal cornice 27 all along the front of the tray located at the height of the upper end of the tray 25. The shower tray further comprises a drain 28 for the discharge of waste water. The bung 28 may be a standard bung model but may also be specific, for example a siphoid bung which can advantageously be molded in the factory within the monoblock structure. Furthermore, the shower tray comprises a cover 30 for hiding the existing vacuum below the shower tray and the support means 32 adjustable in height installed under the tray, behind the front cornice 27. As described in detail in relationship with Figures 5a-5c , this cover can, if necessary, be deleted.

De préférence, le bac de douche est en résine acrylique, en gelcoat ou tout autre matériau composite. Ce dernier peut par ailleurs être avantageusement découpé au moyen d'une scie manuelle ou électrique.Preferably, the shower tray is acrylic resin, gelcoat or any other composite material. The latter can also be advantageously cut by means of a manual or electric saw.

L'installation de douche comprend des moyens de raccordements au réseau d'alimentation en eau (représentés à la figure 4), des moyens de distribution d'eau, par exemple des robinets ou un mitigeur, et des pieds réglables en hauteur (32). Les moyens de distribution d'eau 29 peuvent, avantageusement, être préinstallés sur la structure monobloc en usine mais on peut tout aussi bien utiliser des moyens de distribution d'eau d'origine posés sur les murs de la salle de bain.The shower installation comprises means for connection to the water supply network (shown in FIG. figure 4 ), water distribution means, for example faucets or a mixer, and adjustable feet (32). The water distribution means 29 may advantageously be pre-installed on the monobloc structure in the factory, but it is equally possible to use original water distribution means placed on the walls of the bathroom.

De préférence, la corniche frontale 27 est adaptée pour recevoir des portes ou parois. Ces portes ou parois peuvent, le cas échéant, être coulissantes ou battantes.Preferably, the frontal cornice 27 is adapted to receive doors or walls. These doors or walls may, if necessary, be sliding or swinging.

Alternativement, comme on le voit sur la figure 3, l'installation comprend aussi une pompe 31, par exemple munie de moyens de déclenchement automatique, disposée, par exemple, dans l'espace situé entre le mur de la salle de bain et la paroi antérieure du bac de douche, et destinée à aspirer les eaux usées depuis la bonde du bac pour les convoyer jusqu'au conduit d'évacuation des eaux usées de la salle de bain lorsque le siphon a été retiré afin de positionner le bac à la hauteur la plus basse possible.Alternatively, as seen on the figure 3 , the installation also comprises a pump 31, for example provided with automatic triggering means, arranged, for example, in the space between the wall of the bathroom and the front wall of the shower tray, and intended to suck the wastewater from the bunker of the tank to convey them to the sewage drain of the bathroom when the siphon was removed to position the tray at the lowest possible height.

Par ailleurs, conformément à certaines normes liées aux produits électriques (pompe) dans un produit sanitaire présent dans une salle de bains, la pompe est accessible au moyen d'une trappe d'accès (non représentée) présente sur le bac.Furthermore, according to certain standards related to electrical products (pump) in a sanitary product present in a bathroom, the pump is accessible by means of an access door (not shown) present on the tray.

L'installation peut aussi comprendre des accessoires tels qu'une unité de contrôle, un banc, un appareil de production de vapeur, une source de lumière, un dispositif de séchage, une source de son ou de vidéo ou un lavabo. Alternativement, un banc, un siège ou une barre de support peuvent aussi faire partie intégrante de la structure monobloc du bac.The installation may also include accessories such as a control unit, a bench, a steam generator, a light source, a drying device, a sound or video source, or a bathroom sink. Alternatively, a bench, a seat or a support bar can also be an integral part of the one-piece structure of the tray.

Dans un exemple de procédé de remplacement selon l'invention, la baignoire existante est tout d'abord extraite de son emplacement. La structure monobloc du bac de douche est ensuite découpée aux dimensions de l'emplacement laissé vacant à la place de l'ancienne baignoire de manière à ce que le bac de douche cache la totalité de cet emplacement. Lors d'une troisième étape, le bac de douche dimensionné de manière adéquate est mis en place dans l'emplacement laissé vacant par l'ancienne baignoire et la hauteur du bac est réglée au moyen des pieds réglables 32 situés sous le bac. Finalement, vient une quatrième étape durant laquelle la bonde d'évacuation du bac de douche de remplacement est raccordée au conduit d'évacuation des eaux usées présent dans la salle de bain.In an exemplary replacement method according to the invention, the existing bath is first extracted from its location. The monobloc structure of the shower tray is then cut to the dimensions of the vacant place in place of the old bathtub so that the shower tray hides the entire location. In a third step, the suitably dimensioned shower tray is placed in the location left vacant by the old bathtub and the height of the tray is adjusted by means of the adjustable feet 32 located under the tray. Finally, there is a fourth step during which the drain of the replacement shower tray is connected to the sewage pipe in the bathroom.

Le procédé comprend alternativement, juste avant la quatrième étape de mise en place du bac de douche, une étape intermédiaire durant laquelle une pompe est raccordé entre la bonde du nouveau bac de douche et les moyens d'évacuation d'eau présents dans la salle de bain.The method alternately comprises, just before the fourth stage of installation of the shower tray, an intermediate step during which a pump is connected between the drain of the new shower tray and the water evacuation means present in the shower room. bath.

Alternativement, le procédé comprend une étape supplémentaire durant laquelle des moyens de distribution d'eau 29 présents sur le bac de douche sont raccordés aux moyens d'alimentation en eau présents dans la salle de bain. Comme mentionné précédemment, les dits moyens de distribution d'eau peuvent avantageusement comprendre des robinets et/ou un ou plusieurs régulateurs de pression et/ou de température bien connus de l'homme du métier.Alternatively, the method comprises an additional step during which water distribution means 29 present on the shower tray are connected to the water supply means present in the bathroom. As mentioned above, said water distribution means may advantageously comprise taps and / or one or more pressure and / or temperature regulators well known to those skilled in the art.

La figure 4 représente l'état de l'installation de douche selon l'invention lors de l'étape de raccordement des moyens de distribution d'eau présents sur le bac de douche aux moyens d'alimentation en eau présents dans la salle de bain. On peut voir, en transparence à travers le bac, les moyens de distribution d'eau 41 du bac de douche, de préférence préalablement montés en usine, raccordés au circuit d'alimentation en eau 42 de la salle de bain.The figure 4 represents the state of the shower installation according to the invention during the step of connecting the water distribution means present on the shower tray to the water supply means present in the bathroom. It can be seen, in transparency through the tray, the water distribution means 41 of the shower tray, preferably previously mounted at the factory, connected to the water supply circuit 42 of the bathroom.

Le procédé de remplacement selon l'invention a l'avantage qu'il puisse être mené par une personne seule. En effet, compte tenu du fait que les parties des murs brutes mises au jour lors de l'extraction de la baignoire existante sont recouvertes totalement par le bac de douche de remplacement, il n'est plus nécessaire de peindre ni de carreler cette partie cachée. De plus, compte tenu du fait que le bac de douche est supporté par des pieds réglables en hauteur et fermé à sa base, soit uniquement par la corniche, soit par la corniche et le couvercle, l'intervention d'un maçon pour mettre à niveau le sol de la salle de bain n'est plus nécessaire. Par ailleurs, compte tenu du fait que les robinets et accessoires sont de préférence montés en usine sur le bac de remplacement, aucun perçage n'est nécessaire. Finalement, puisqu'il est possible de découper le bac de douche au moyen d'une scie manuelle ou électrique pour l'adapter aux dimensions de la salle de bain et, puisque le bac de douche est adapté pour le montage de portes ou parois sur la corniche frontale, une personne seule est à même de découper le bac aux dimensions voulues, de le mettre en place et de raccorder les moyens d'alimentation et d'évacuation. Par conséquent, le procédé selon l'invention évite que différents corps de métier doivent intervenir, ce qui réduit d'autant plus le temps nécessaire à la rénovation et diminue sensiblement les coûts. En suivant le procédé de remplacement d'une baignoire existante par une douche selon l'invention, une personne seule est, en général, à même de remplacer une baignoire par une douche en une journée de travail.The replacement method according to the invention has the advantage that it can be conducted by a single person. Indeed, considering that the parts of the raw walls uncovered during the extraction of the existing bath are completely covered by the replacement shower tray, it is no longer necessary to paint or tile this hidden part . In addition, considering that the shower tray is supported by feet adjustable in height and closed at its base, only by the cornice, or by the cornice and the lid, the intervention of a mason to put in level the floor of the bathroom is no longer necessary. In addition, considering that faucets and accessories are preferably factory mounted on the replacement tank, no drilling is required. Finally, since it is possible to cut the shower tray using a manual or electric saw to adapt it to the dimensions of the bathroom and, since the shower tray is suitable for mounting doors or walls on the frontal cornice, a single person is able to cut the tray to the dimensions, to put in place and connect the means of supply and evacuation. Therefore, the method according to the invention avoids that different trades must intervene, which further reduces the time required for renovation and substantially reduces costs. By following the procedure of replacing an existing bath with a shower according to the invention, a single person is usually able to replace a bath with a shower in a day's work.

De plus, comme représenté aux figures 5a, 5b et 5c, l'installation de douche est complètement accessible aux personnes à mobilité réduite. En effet, dans le cadre d'une rénovation de salle de bain dans le logement d'une personne à mobilité réduite, l'installation selon l'invention permet de limiter la hauteur du seuil au minimum en faisant usage d'une pompe d'évacuation. Cette dernière fait alors transiter les eaux usées depuis la bonde d'évacuation du bac de douche directement jusqu'au conduit d'évacuation des eaux usées de la salle de bain. C'est donc l'absence d'un siphon qui, dans ce cas, permet de régler la hauteur du bac de douche au minimum sans se soucier de la hauteur du point d'évacuation du bac vis-à-vis des moyens d'évacuation de la salle de bain. Ceci permet par exemple d'obtenir une hauteur de seuil inférieure à 7cm.In addition, as represented Figures 5a, 5b and 5c , the shower facility is fully accessible to people with reduced mobility. Indeed, in the context of a bathroom renovation in the housing of a person with reduced mobility, the installation according to the invention makes it possible to limit the height of the threshold to the minimum by making use of a pump of evacuation. The latter then passes the wastewater from the shower drain outlet directly to the sewage drain of the bathroom. It is thus the absence of a siphon which, in this case, makes it possible to regulate the height of the shower tray to the minimum without worrying about the height of the point of evacuation of the tank vis-à-vis the means of evacuation of the bathroom. This allows for example to obtain a threshold height of less than 7 cm.

Sur la figure 5a, le bac de douche est aux dimensions d'origine et on fait usage d'une pompe. En absence d'un siphon, la hauteur du seuil est donc limitée au minimum. Sur la figure 5b, le bac de douche a été découpé aux dimensions minimum et la hauteur de seuil est plus importante à cause de l'espace vertical nécessaire pour l'utilisation d'un siphon. Un couvercle 30 est donc posé pour cacher le vide, le siphon et les moyens de support réglables en hauteur. Sur la figure 5c, le bac de douche est découpé aux dimensions minimum et on fait usage d'une pompe. Dans ce cas, la hauteur du seuil est minimum et on a plus besoin du couvercle pour cacher le vide.On the figure 5a , the shower tray is original dimensions and uses a pump. In the absence of a siphon, the height of the threshold is therefore limited to the minimum. On the figure 5b , the shower tray has been cut to the minimum dimensions and the threshold height is greater because of the vertical space required for the use of a siphon. A lid 30 is thus placed to hide the vacuum, the siphon and the support means adjustable in height. On the figure 5c , the shower tray is cut to the minimum dimensions and uses a pump. In this case, the height of the threshold is minimum and the lid is no longer needed to hide the void.

L'installation de douche selon l'invention apporte par ailleurs un autre avantage par le fait qu'elle est adaptée pour recevoir des portes ou parois. De tels moyens de fermeture, disposés directement sur la corniche frontale, assurent une étanchéité qu'une porte, paroi ou rideau posé devant la corniche ne peut garantir (l'eau tomberait sur le sol de la salle de bain car il est quasi-impossible de coller la porte ou la paroi tout contre la corniche). De plus, compte tenu du matériau et de la forme de la corniche, le montage des portes ou parois se révèle une opération simple et rapide, ce qui réduit d'autant plus le temps nécessaire à la rénovation et les coûts.The shower installation according to the invention also provides another advantage in that it is adapted to receive doors or walls. Such closing means, arranged directly on the frontal cornice, ensure a tightness that a door, wall or curtain placed in front of the cornice can not guarantee (the water would fall on the floor of the bathroom because it is almost impossible to stick the door or the wall all against the cornice). In addition, given the material and shape of the cornice, the assembly of the doors or walls is a simple and fast operation, which reduces all the more time needed for renovation and costs.

L'installation selon l'invention apporte finalement l'avantage que la mise en place du bac de douche, compte tenu de sa structure monobloc, ne nécessite pas forcément que ce dernier soit supporté latéralement par les murs de la salle de bain. Un cadre de soutien n'est pas non plus nécessaire.The installation according to the invention finally brings the advantage that the installation of the shower tray, given its monobloc structure, does not necessarily require that it is supported laterally by the walls of the bathroom. A support framework is also not necessary.

L'installation de douche selon l'invention, de part ses dimensions et sa structure qui peut être découpée au moyen d'une simple scie, permet en outre de remplacer un grand nombre des baignoires de taille standard.The shower installation according to the invention, because of its size and structure which can be cut by means of a simple saw, also allows to replace a large number of standard size baths.
