Starting from the known method is proposed according to the invention that a large tile as flooring forced into a curved shape and with adhered to the substrate, and is held by the adhesion to the substrate in the curved shape. The method according to the invention, by means of which a sanitary unit according to the invention is produced, is equally distinguished by its abovementioned advantages.

Preferably, in a method according to the invention prior to bending at least one cut or cut is cut into the large tile. Cutouts can accommodate in particular the bottom plate penetrating connection elements. By cutting into the tile edges or steps in the flooring can be made

Preferably, in a method according to the invention, the large tile on a prefabricated molding element is forced into the curved shape, the molding element forming part of the substrate. The deformation directly on a prefabricated substrate allows further favors the division of labor manufacturing the sanitary unit.

Preferably, in such a method according to the invention, the large tile is pressed onto the molding element. So the large tile can be fixed at the same time and placed in the desired curved shape of the useful side.

Alternatively, the large tile can be sucked by a negative pressure on a mold element. Ceramic floor coverings have a surface roughness that allows them to be sucked on a shape with only a slight amount of false air. The attachment of plate-shaped components by means of suppression of handling equipment, for example, from the handling of OSB and particle board in

Carpentry generally known.

Alternatively, in another method according to the invention, the

Large tile by its own weight and / or the weight of the

Substrate on the form element.

Preferably, in a method according to the invention, the large tile is arranged with the useful side pointing downwards, and at least one layer of the substrate is placed on an underside of the large tile opposite the useful side cast. The substrate can be so particularly easy, for example, filled with a foam.
