Overview

Project facts: Delivered 2015 · Istanbul, Türkiye · Scope: Turkish bath (hammam), steam rooms, pools, sauna · Equipment: Condair steam generators

This is a Sauna Dekor project. We are a manufacturer first and a turnkey wet-area contractor second: cabins, benching, marble and mosaic are made in our own Istanbul workshop, then installed by our own crews. Founded 1987, 40th year, work delivered in 41+ countries.

This page records the spa thermal areas built for the Wyndham hotel in Istanbul. The zoneslisted for the project are Turkish bath, hammam, steam rooms, pools and sauna.

Scope of work

A hotel wet circuit with a marble hammam at its centre, steam rooms and a sauna alongside,and the pool hall completing the sequence. Our photographic record covers all four zones. The work was taken as one wet-area package — falls and tanking, marble and mosaic, cabins,generators and heaters, ventilation terminals, drainage and commissioning — rather than as a supply-only contract.

The hammam as a slab, not a room

A marble hammam is really a heated slab with walls around it. The navel stone and the benches are warmed from below; air temperature stays moderate and humidity is held high enough that the skin does not dry. That makes thermal mass the governing property: the room takes along soak to reach working surface temperature and should be brought on well before the spa opens. It also makes the kurna positions the first thing to be set, because the washing points fix bench lengths, the position of the navel stone and the direction of every drainage fall.Our what is a Turkish bath page explains the room type in more detail.

Steam generators, sauna heaters and recovery

General practice sizes a dry cabin at roughly a kilowatt of stone-heater output per cubic metre of volume, with additions for glazing and for masonry surfaces inside the envelope, and sizes a steam enclosure on volume with a correction for the finish material. Mosaic laid on a masonry backing is a large thermal mass and needs a proportionally bigger generator than the same volume built over insulated board. Then comes the hotel factor: headroom for dooropenings. A generator that satisfies the volume calculation but has no reserve will feel weakexactly when the spa is busiest, and that is the only time guests form an opinion of it.

Pool hall, tanking and grout

The pool hall carries the building risk. Vapour from the water condenses on the coldestsurface it can find, so the hall needs dehumidified supply, extract enough to hold it slightlynegative against the dry side of the hotel, and warm air moved across the glazing. Wet rooms were tanked before finishes: bonded membrane over the screed, reinforcing tape into corners,movement joints and penetrations, dressed into the gullies, carried up past splash height, with falls formed in the screed. Epoxy grout in the permanently wet rooms — cement grout in a vapour-loaded room breaks down and then telegraphs every joint. Product pages:hammam,steam room andpools.

What we solved on site

The recurring conflict in a marble hammam is between drainage geometry and stone layout.Falls have to run from every washing point and from beneath the navel stone to the gullies,while the marble wants to be laid in whole, book-matched pieces without awkward cuts. Those two requirements cannot both be resolved with a diamond blade in a finished room. We set gully and kurna positions first, worked the falls from them, and cut the slabs in ourIstanbul workshop against the drainage drawing,so the stone arrived on site already reconciled with the falls.

Frequently asked questions

Why does a hammam take so long to warm up?

Because the heat is stored in stone rather than in air. The navel stone and benches are warmed from below and need a long soak to reach working surface temperature, so the room is brought on before the spa opens rather than at the first booking.

How much bigger does a mosaic steam room’s generator need to be?

Larger than a volume calculation alone suggests. Mosaic on a masonry backing is a substantial thermal mass that must be brought up to temperature before the room holds steam, and a hotel also needs reserve for constant door openings.

Which comes first, the drainage falls or the marble layout?

Drainage. Gully and washing-point positions are fixed, the falls are worked from them, and the slabs are then cut to suit — in the workshop, against the drainage drawing, not on site with a diamond blade.

Why epoxy grout instead of cement grout?

Because a permanently vapour-loaded room breaks cement grout down over time, and once it starts to go it telegraphs every joint. Epoxy grout is used throughout the steam rooms and hammam wet zones.
