Scope of work

A full city-hotel wet circuit rather than a single room: a main marble hammam with kurna washing points, a smaller VIP hammam for private bookings, steam rooms, a timber sauna,heated stone loungers and the finishes around the pool hall. Our package covered the room build-up — screeds and falls, tanking, marble and mosaic — together with the cabins, the heating and generator equipment, ventilation terminals, drainage and commissioning.

Heated marble and heated loungers

The navel stone, the benching and the loungers are all warmed from beneath. The designvariables are slab thickness, circuit spacing and flow temperature, and they are chosen together: circuits set too shallow give warm and cold stripes a guest can feel through a towel, circuits set too deep never bring the surface up. Heated loungers add a second constraint, because a body lying still on stone draws heat out of one patch continuously — the circuit under a lounger has to be denser than the circuit under a walking surface. None of this is guesswork on site; it is set out on the shop drawings before the marble is cut.

What we solved on site

City hotel spas are usually below ground: everything the wet areas need — fresh air,extract, drainage falls, plant access — competes for the same slab-to-slab height as the hotel’s own services. We fixed the finished floor levels and drainage falls first, then the wet-room ceiling heights, and only then let the duct routes be drawn, so the hammam dome andthe sauna’s top bench kept the height they needed. Marble and cabins were dry-assembled in ourIstanbul workshop and numbered before delivery.More on the approach athotel spa design.
