Abstract

A method for replacing a bathtub (1) with a shower platform providing the step of removing the bathtub (1) with entire bathtub body (3) from the containing walls (5a-5d), obtaining a recess (4) defined by a containing wall, which is removed up to leaving a shoulder (11). The step of removing the bathtub (1) does not involve the original taps (10). Furthermore, the fragments and debris (7) produced during the demolition of the walls (5a-5d) are stored in the recess (4') defined by the shoulder (5a-5d), which form the shoulder (11), thus avoiding to dispose of the produced debris and the fragments. The layer of fragments (7) can then be flattened to provide a base frame (8) on which a shower platform (20) is then located. For making the base frame (8) substantially homogeneous it is possible to add filling material, for example polyurethane foam (50). The shower platform (20) has size such that it is oversized with respect to the standard size of a bathtub (1). In this case, the shower platform (20) is subject to a preliminary cutting step for fitting it to the size of the shoulder. At the uncovered surfaces (25), when removing the bathtub (1), a lining sheet (15) is applied.

Description

The present invention relates to the field of interior renovation and precisely it relates to a method for replacing a bathtub with a shower platform.

Background of the invention

In modern life, a particular attention is paid to water consumption and other factors such as the reduction of the room sizes of houses and flats, and then of the bathrooms, that have brought with time to a large diffusion of the shower cabinets and to a subsequent decrease of the demand for bathtubs.
Also owing to the presence in families of old or of disabled people a shower platform is preferable to a bathtub, in particular, for difficulties met by such categories of people to have access to the bathtub.
Therefore, in the houses of old construction the need is felt to replace the bathtub present in the bathroom with a shower platform. This change is carried out through a succession of demolition and of construction works that time consuming and expensive.
In particular, during the demolition of the bathtub a big amount of debris is created that has to be disposed of and is, furthermore, associated with damaging neighbouring tiles with subsequent need of changing them.
This step is very complicated also for a difficulty of finding tiles of the same type of the preexisting ones.
Another drawback of the used techniques for replacing a bathtub with a shower platform the difficulty of finding on the market shower cabinets of standard corresponding size to that of the bathtub. This requires making a shower platform to measure, with further costs.
FR 2882243 discloses a shower installing system for bathroom having wallboards with concave surface applied against existing wall and side surfaces delimiting ceiling space, destined for passage of valves, between existing wall and front surface. The wallboards are molded in modular dimensions and include sectile parts (20) for an adjustment to the standard overall dimensions
FR 2860411 discloses a shower cabinet comprising a tray having a bottom which leads to an outlet, fitted with an assembled drainage board on which a person can stand while towelling off after showering. The drainage board forms an extension to the tray and acts as a dry area. The cabinet has a hinged panel which can be set parallel to the drainage board's edge or perpendicular to it, separating the shower tray from the dry area.

Summary of the invention

It is therefore a feature of the present invention to provide a method for replacing a bathtub with a shower platform that does not require substantial construction works for its actuation.
It is, furthermore, a feature of the present invention to provide a method for replacing a bathtub with a shower platform that is easy and quick to carry out.
It is also a feature of the present invention to provide a method for replacing a bathtub with a shower platform without making large amounts of debris.
It is a further feature of the present invention to provide a method for replacing a bathtub with a shower platform that avoids changing the existing taps of the bathtub with new taps.
It is another feature of the invention to provide a method for replacing a bathtub with a shower platform that is particularly adapted to disabled people.
These and other objects are achieved by a method for replacing a bathtub with a shower platform having a lateral edge defined between an upper border and a lower rim, said method comprising the steps of:

removing an existing bathtub that is defined by containing walls in order to create a recess of corresponding size as defined by said containing walls of the bathtub, said step of removing comprising the step of pulling down the bathtub containing walls up to leaving a shoulder which defines said recess;
forming a base frame by introducing fragments, or debris, deriving from the above described demolition in said recess defined by said shoulder, said base frame formed by a layer of fragments, or debris, within said shoulder;
levelling said layer of fragments, or debris, within said shoulder, in order to conform substantially the thickness of the debris level;
introducing a filling material in spaces present between the fragments, or debris, in order to level said base frame same in a way substantially uniform that assists a next step of arranging a shower platform,
finishing said shoulder;
arranging a shower platform of determined size on said layer of fragments, or debris;
cutting said shower platform up to the size of said shoulder;
levelling said shower platform and fixing it to said shoulder;
wherein said shower platform is associated with a shower cabinet comprising a frame consisting of a plurality of vertical rods adapted to support a plurality of side walls;
wherein said shoulder and said base frame are configured such that the lower rim of said shower platform is arranged at the same level of the floor of the room in which it is installed.

Preferably, the shower platform can be made of a material selected from the group comprised of:

plastic material, in particular an acrylic resin;
ceramic material.

The step of cutting the shower platform up to the size of said shoulder is provided because the shower platform is oversized with respect to the standard size of the bathtubs. Therefore, before being located on a base frame made with masonry material and/or with the fragments generated by the demolition of the bathtub, the shower platform is subject to a cutting step in order to fit it to the desired size. This way, it is possible to mould a single universal shower platform, or a limited series of shower platforms, and then fitting it to the size of the shoulder, by cutting the exceeding part.
In particular, the base frame may have a height set between 2 and 50 cm, advantageously between 4 and 30 cm.
More in detail, the shower platform has the following size:

width set between 60 and 80 cm;
length set between 160 and 180 cm.

Alternatively, the shower platform can be selected among a plurality of shower platforms of different size, each of which having corresponding size to traditional bathtubs.
In particular, the vertical rods of the shower cabinet are configured in such a way to be capable of approaching/moving away from each other for adapting to the size of the shower platform. The shower platform can be defined laterally by at least one wall of the room in which is installed.
In particular, when removing the bathtub, the original taps are not pulled out, whereby the final shower platform comprises the taps of the original bathtub. This reduces remarkably the work made by the operator for carrying out the transformation of the bathtub into a shower platform, with subsequent time saving and reduced costs.
Since when removing the bathtub portions of wall are uncovered that used to define laterally the bathtub, said portions of wall are coated by at least one lining sheet. In particular, the, or each, lining sheet coats the plaster uncovered when removing the bathtub.
Therefore, the lining sheet coats the side walls of the final shower platform only for a measured height. This solution allows to limit remarkably the finishing work that has to be carried out after the demolition of the bathtub. Advantageously, the shower platform comprises at least one lining sheet that defines laterally at least one wall side, or the wall of the room in which it is installed.
In particular, the or each lining sheet can be connected to the above described portions of wall, by means of screws, glue for building industry, etc.
In particular, the lining sheet can be made using a plurality of tiles, for example the same tiles that cover the walls of the room in which the shower platform is installed.
Alternatively, the lining sheet is made using at least one plate of plastic material.
In particular, the sheets are located in order to result flush with the walls of the bathroom that are not involved with removing the bathtub, or with the possible tiles fastened to them.
Advantageously, said filling material is polyurethane foam, that is arranged in spaces present between the fragments, or debris, in order to level the base frame same. This way, it is possible to provide a platform substantially uniform that assists the next step of arranging the shower platform.
In particular, the lining sheet has at least one graphical sign selected from the group comprised of:

an image;
a text;

Advantageously, the graphical sign can be made on the vertical sheet by means of litographic techniques.

Brief description of the drawings

Further characteristic and the advantages of the method for replacing any bathtub with a shower platform, according to the invention, will be made clearer with the following description of an exemplary embodiment thereof, exemplifying but not limitative, with reference to the attached drawings, in which like reference characters designate the same or similar parts, throughout the figures of which:

Figures from 1 to 8 show diagrammatically perspective views and an elevational side view of a possible succession of steps obtainable by the method, according to the invention, for replacing a bathtub with a shower platform.

Description of a preferred exemplary embodiment

With reference to figures from 1 to 8, the method for replacing a bathtub 1 associated with taps 10 with a shower platform, according to the invention, begins with the step of removing the preexisting bathtub 1. This can be effected extracting the still entire bathtub body 3 from the containing walls 5a-5d, as diagrammatically shown in figure 2A, obtaining a recess 4 (figure 4). Preferably, bathtub 3 is pulled out cutting, or crushing in situ the body 3 of the bathtub (figure 2B).
Then, the partial demolition of the containing walls 5a-5d that define recess 4 is carried out. The removing step of bathtub 3 does not involve the original taps 10, such that, in particular, neither the faucets 10a nor the ducts are removed, leaving the shower platform obtained at the end of the operation with the same taps 10 of the original bathtub, thus saving work of the operator. This confers high savings to the client that requires turning the bathtub into a shower platform.
As diagrammatically shown in figure 5, when pulling down the bathtub containing walls 5a-5d, only part of them is involved. In this way, a portion 11 of the walls 5a-5d of height H and any tiles 6 to them connected remain intact.
According to the invention, the fragments and the debris 7 produced during the demolition of the walls 5a-5d are stored in recess 4' defined by the lower portion of walls 5a-5d, which forms a shoulder 11, thus avoiding of disposing of the debris and the fragments produced by the demolition (figure 5).
The layer of fragments 7 that is obtained can then be flattened to provide a base frame 8 on which shower platform 20 is then located. For making the base frame 8 substantially homogeneous it is possible to add filling material, for example polyurethane foam 50 (figure 6). By penetrating, in fact, in the spaces between the fragments 7, the filling material 50 levels the layer of fragments 7 assisting the arrangement of shower platform 20 on base frame 8.
Shower platform 20, preferably of acrylic material, is selected among a plurality of shower platforms of size corresponding to bathtubs of different standard sizes. In general, shower platform 20 is oversized with respect to a bathtub 1 standard size. As shown in figure 7, according to the invention, the shower platform 20 is arranged at a same level of the floor of the room 100 in which the shower platform is installed, which can be on a masonry layer 11'.
Therefore, before being put on a base frame 8, shower platform 20 is subject to a preliminary cutting step for example by a common manual saw, in order to fit it to a desired size.
According to what provided by an advantageous step of the invention, to surfaces 25, or wall portions, which have been uncovered when removing bathtub 1 (figure 6), a lining sheet 15 is applied, for example fixing it to the surfaces 25 by means of nails, screws, glue for building industry (figure 7).
Alternatively, the lining sheets 15 can cover a higher surface, for example up to coating all the height of a shower cabinet 100 associated with shower platform 20 (figure 7).
The lining sheet 15 can be made using tiles 150 like those of the bathroom in which the shower platform is installed (figure 7), or alternatively, can be sheets of plastic material. In this case, the lining sheet 15 can be decorated with images, or text as desired.
The shower cabinet 100 comprises, in particular, a frame consisting of a plurality of vertical rods, for example four rods 101a-101d, adapted to support a plurality of side walls 105. The vertical rods 101a-101d can be approached/moved away with respect to each other for example by means of connection guides 105 mounted telescopically in order to adapt the shower cabinet 100 to the size of shower platform 20.
The foregoing description of a specific embodiment will so fully reveal the invention according to the conceptual point of view, so that others, by applying current knowledge, will be able to modify and/or adapt for various applications such an embodiment without further research and without parting from the invention, and it is therefore to be understood that such adaptations and modifications will have to be considered as equivalent to the specific embodiment. The means and the materials to realise the different functions described herein could have a different nature without, for this reason, departing from the field of the invention. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
