The bathtubs come in models that are either perfectly rectangular or slightly tapered, and are either freestanding, mounted on a base or on legs.  They can be adapted to any bathroom configuration, with installation in the centre of the room, against a wall, in a corner, recessed against 3 walls, or in a sunken design. The edges extend up to a width of 7 in. (17.5 cm). The sleek design of the sinks represents a modern version of the stone washbasins still used in the French countryside.
