As far as installing a hammam in a flat is concerned, the solution suggested by Bertani provides for a box to be built of masonry or other light materials, which is to be insulated and coated internally with mosaic or stoneware. Bertani can attend to the client at all design and production stages, and can make a wide choice of solutions for internal coating available. Inserted into the structure is the steam generator and the crystal door provided by Effegibi. Usually within a hammam there is a seat, a small washbasin or a drinking fountain, with, possibly, a rain shower head. In this latter case, the hamman can be used either as a Turkish bath or as a shower, in order to optimise space.
