To start you needs initially a small course of masonry. Practically all the bathrooms and hammams in Morocco (hotels and riads) are built in Tadelakt. The tadelakt is a parget of lime which allows the sealing and the impermeability of the room. But that costs rather expensive because it is long to work and smooth. But the result is sensational. There is a royal, coloured bathroom or not, who does not need so many accessories to be even more beautiful.
