A hammam built the way hammams are built

The slab and the heat under it

The heated marble slab is the room. It runs at 40-45 °C on the surface, heated from below by a water loop or an electric mat set into the screed, and the whole session happens on it. Getting the temperature even is the craft: the loop spacing tightens at the edges because the perimeter loses heat to the room, and a slab that is warm in the middle and cold at the rim is the commonest fault we are called to fix.

Around it the air sits at 40-50 °C and high humidity — warm, not scalding. That is why people stay an hour, and why a hammam works for a household where a 90 °C sauna would be used by one person.

Zellige is cut, not laid

Real zellige is glazed terracotta chipped to shape by hand, one piece at a time, and assembled face-down into a geometric pattern. It is slow, it is expensive, and it looks nothing like the printed tile sold as zellige. We buy from the same workshops in Fès and Marrakech we have used for years, and we show you the cut pieces before anything goes on a wall.

Where the budget will not carry full zellige, we use it as a band or a niche against tadelakt rather than spreading it thin. A small area of the real thing beats a whole room of the substitute.

Domes, light and water

A pierced dome throws the traditional points of light across the steam. In a Moroccan house we build it as a shallow dome with fibre optics rather than cutting holes in a roof that has to survive winter rain on the Atlantic coast or in the Atlas foothills.

The floor falls to a central drain at 1:50, the benches are warm, and every fitting is brass because it patinates instead of pitting. Chrome in a hammam looks tired in three years.

In short

• Heated marble slab at 40–45 °C, loop spacing tightened at the perimeter
• Hand-cut zellige from Fès and Marrakech workshops — we show you the pieces
• Shallow dome with fibre optics instead of roof penetrations
• Brass throughout, honed stone underfoot, floor falls 1:50 to a central drain
