“Temperature: 40 °C to 50 °C — Humidity: high”
Sauna Dekor designs, manufactures and installs hammams and Turkish baths in Dubai, Abu Dhabi and across the UAE, and has done so since 1987. We build in marble, travertine and Turkish glass mosaic, with a heated göbektaşı engineered for high-volume hotel and spa use. Design, in-house manufacturing, shipping and on-site installation come from one contractor, under one warranty. Derived from the Arabic word "Hamm," meaning warmth, hammams have been an integral part of cultures like the Ottoman Empire. Today, these zones of spas not only provide a relaxing retreat but also contribute to overall well-being.
1. Understanding the Tradition: Delve into the historical roots of hammams, influenced by the grandeur of Roman baths. Explore the fusion of Turkish and Anatolian bath cultures, defining the essence of crucial water structures.
2. Initial Stages in Construction:The journey of hammam construction begins with thorough exploration and examination of the chosen site. Client collaboration plays a pivotal role, shaping the project according to their vision. The meticulous design of the heating system and model dimensions ensures a functional and aesthetically pleasing.
3. Construction Process:
a. Quality Materials and Functional Design: Emphasize the importance of using quality materials during hammam construction, incorporating both traditional Turkish bath materials and cutting-edge technology. Hygienic and easy-to-clean materials are crucial, especially in high-heat zones like the navel stone section..
b. Heating Options: Discuss the heating options available, such as hot water pipes or electric systems, considering individual needs. Ensure proper design alignment, effective heating, and ventilation systems for optimal performance.
Stages of Production
Outline the key steps in constructing a dream Turkish bath
a. Survey and Prep Phase: Initiate the process with a thorough survey and preparation.
b. Material Choices: Involve clients in decisions on marble, plumbing, and heating systems, because the marble surface temperature is what the guest feels, not the air.
c. Ergonomic Solutions: Strike a balance between aesthetics and function, utilizing services like water jet and CNC cutting for marble.
Important Factors in Construction
Four decisions set whether a hammam works as a treatment room or only photographs as one:
a. Optimal Marble Heating: Heat the marble, not the air: the göbektaşı and the benches are the emitter, and the room is held at 40-50 °C around them.
b. Ventilation and Insulation: Plan for an efficient ventilation system and use high-quality insulation for durability.
c. Aesthetics and Durability: Implement stylish elements like vaults, domes, stretch ceilings, and fiber LEDs, while ensuring durability with steel mesh and compressed panels.
Materials Used in Construction
The navel stone carries the heating circuit, so its material has to move heat evenly and survive thermal cycling without crazing. We specify dense, low-porosity marble for the slab and the benches, with thickness chosen against the circuit below rather than against appearance — too thin and the surface runs hot in stripes above the pipes, too thick and it never reaches temperature within the warm-up window. Wall and vault surfaces sit on a fully tanked build-up, because a hammam is a saturated wet room and every joint is a potential path. Kurna basins are carved from the same stone family so the room reads as one piece, and their fill rate and water temperature are part of the treatment sequence, not a plumbing afterthought. Fittings are selected for the water chemistry first and the finish second: a tap that looks correct and corrodes in its second season has failed.
Cost of Construction
Cost in a hammam is driven by the build-up, not the finish. The largest variables are the stone — type, thickness and how much of it is carved rather than cut — the heating circuit under the slab and its control, the tanking and waterproofing specification, and the mechanical plant that holds temperature and humidity. Room volume matters more than floor area, because both the heat load and the air changes follow it.
The part operators underestimate is plant. On a recent Gulf project the hammam halls carried a total load in the high seventies of kilowatts, of which only about a third was the steam plant itself; the rest was the building — the slab, the surfaces, the air. A room specified on finish alone will be under-plant and will never hold its condition.
A residential hammam and a hotel hammam can share a language and still be different projects. The hotel room runs twelve hours a day, seven days a week, against a hot ambient, and every specification decision has to be made for that duty rather than for occasional use.
Models and Prices
Three traditions, three different rooms. The Turkish hammam is built around a heated navel stone, with the bather lying on warmed marble while the room is held around 40–50 °C at high humidity — the slab, not the air, does the work. The Moroccan bath runs wetter and warmer at the surface, is organised around steam and washing rather than around a central stone, and its finishes are usually tadelakt rather than marble. The modern interpretation keeps the thermal behaviour but changes the geometry: simpler forms, concealed lighting, glass where tradition used masonry, and controls the operator can actually run. The choice changes the construction, not only the look — the heating circuit, the drainage falls and the plant are different in each. We would rather establish which room you are building before anything is drawn. A hammam is not a steam room with marble in it: the heated göbektaşı and the benches are the heat emitter, so the slab rather than the air does the work while the room is held at 40-50 °C at high humidity. A room built without underfloor and under-bench heating feels cold at exactly the same air temperature. A hammam in a private home takes 3–8 weeks to build; a large project takes up to 12 weeks.

Turkish Bath
Immerse yourself in the timeless allure of Traditional Turkish Baths, a blend of history and holistic wellness. Sauna Dekor has manufactured hammams since 1987 and is in its fortieth year, with a team of 19 people in Basaksehir, Istanbul; it crafts an authentic experience with meticulous planning, quality materials, and an engineering review of the heating, tanking and drainage before anything is ordered. From dressing areas to the heating zone, each element contributes to the rejuvenating journey. The cost of your dream hammam project varies based on size, material quality, and logistics. Cost is set by three things we can quote against: the marble specification, the heated surface area in square metres, and whether the tanking has to be built or adapted.
Moroccan Bath
Discover the allure of Moroccan Baths, where temperatures range between 40°C and 50°C, offering a rejuvenating experience. Sauna Dekor, manufacturing since 1987 and in its fortieth year, brings you the authentic Moroccan Baths, complete with heat, humidity, black soap massages, and aromatic treatments. Influenced by Roman bathhouses, Moroccan Hammams retain the original bathing ritual. The construction emphasizes proper materials, including prefabricated polystyrene panels, stone surfaces, and specially designed benches. Experience the benefits of muscle relaxation and thorough cleansing in a carefully crafted environment.
Modern Hammam
Experience the rejuvenation of Modern Hammams with Sauna Dekor Spa & Solutions. As traditional Turkish baths evolve, our modern projects blend high technology with contemporary architecture, bringing you the purifying power of water. Critical factors, including material quality, technical features, and design details, are fixed in the specification before construction starts, not resolved on site. In its fortieth year, with a team of 19 people manufacturing in Basaksehir, Istanbul under TS EN ISO 9001:2015 and deliveries in 41+ countries, our team ensures each modern Turkish bath reflects a seamless fusion of tradition and innovation. From hotels to private residences, Sauna Dekor transforms dreams into reality. A modern hammam differs from a traditional one in one measurable way: the heat comes from an electric underfloor and under-bench circuit instead of a wood-fired külhan, so the room can be zoned off when the spa is closed and brought back to its 40-50 °C working condition without firing a furnace.

What temperature does a hammam run at, and how long does it take to build?
| Type | Temperature | Relative humidity | Heated göbektaşı | Build time |
|---|---|---|---|---|
| Turkish hammam | 40–50 °C | High | Yes | 3–8 weeks (home), up to 12 (large) |
| Moroccan bath | 40–50 °C | High | Optional | 3–8 weeks (home), up to 12 (large) |
| Modern steam hammam | 42–48 °C | 100 % | Yes | 3–8 weeks (home), up to 12 (large) |
| Room | Internal area | Room volume | Steam generation | Connected load |
|---|---|---|---|---|
| Villa steam hammam, glass mosaic | 2.3 m² | 5.2 m³ | Condair Sigma 8 · 8 kg/h | 6.0 kW · 400 V 3-phase or 230 V 1-phase |
| Villa hammam, natural travertine | 4.1 m² | 9.5 m³ | Condair Sigma 15 · 15 kg/h | 11.3 kW · 400 V 3-phase |
| Hotel steam room, Dubai tower | 5.5 m² | 12.6 m³ | Condair Sigma 15 · 15 kg/h | 11.3 kW · 400 V 3-phase |
| Hotel steam room, Dubai tower | 6.5 m² | 14.9 m³ | Condair Sigma 23 · 23 kg/h | 17.3 kW · 400 V 3-phase |
| Hotel hammam hall, resort spa | 64–69 m² | 153–166 m³ | Two steam generators, 20 kW + 5 kW | 76–79 kW including floor, wall and bench heating |
Steam demand follows room volume, not floor area. We allow 0.5–0.6 kg/h of steam per cubic metre in an acrylic cabin, 0.75–1.0 kg/h per cubic metre in a tiled and insulated room, and 1.0–1.4 kg/h per cubic metre in marble or stone, because stone stores cold and needs the extra output at start-up. Every square metre of glass adds roughly 1.2 m³ to the design volume.

FAQ
Frequently asked questions
What is a hammam and how is it different from a sauna?
A hammam is a wet heat room finished in marble or mosaic, held at 40–50 °C at high humidity, centred on a heated marble platform called the göbektaşı. A sauna is dry heat at a much higher temperature. In a hammam you are washed and scrubbed; in a sauna you sweat and cool.
Who builds hammams in Dubai?
Sauna Dekor designs, manufactures and installs hammams in Dubai and across the UAE. We manufacture in our own facility, ship to site and install with our own team, so the marble, the heating, the waterproofing and the ventilation are one contract rather than four suppliers.
Last updated: 6 November 2026
How much does a hammam cost in Dubai?
Cost is driven by marble selection, room size, whether the göbektaşı is heated, and whether the room is new-build or a retrofit into an existing wet area. We price each hammam against its own drawings rather than a rate card — send us the plan and we will quote it. Hotel hammams are priced per project. We issue a fixed price after a site survey.
How long does it take to build a hammam?
A hammam in a private home takes 3–8 weeks to build; a large project takes up to 12 weeks. A complete villa spa package with several rooms runs 12–16 weeks. Hotel projects run longer because approvals and MEP coordination sit on the critical path, not manufacturing.
What materials are used in a Turkish hammam?
Marble or travertine for the floor, walls, basins (kurna) and the göbektaşı; Turkish glass mosaic where a lighter finish is wanted; a full waterproofing membrane behind everything; steam-resistant adhesive and grout; and insulation under the heated slab. The dome and its light openings are structural, not decorative.
What is a göbektaşı and does it have to be heated?
The göbektaşı is the raised marble platform at the centre of the hammam where the scrub and foam massage happen. It is heated from below. An unheated platform changes the treatment completely — the heat is what opens the skin before keseleme — so we build it heated as standard.
Do I need approvals to build a hammam in Dubai?
Yes. Electrical work needs DEWA approval, the fit-out needs Dubai Municipality sign-off, and a commercial facility needs Dubai Civil Defence approval. In an apartment or a managed community you will also need the building owner’s consent. We prepare the documentation as part of the scope.
What is the difference between a Turkish hammam and a Moroccan bath?
A Turkish hammam is a built room — marble, dome, heated göbektaşı — and the ritual is scrub and foam. A Moroccan bath is primarily a treatment, using black soap and rhassoul clay, and it can be delivered in a steam room without a göbektaşı. Many UAE clients build both.

What the hammam plan is inherited from
A hammam is a sequence rather than a single room, and that sequence is older than any of the equipment now used to serve it. The cold, warm and hot chambers, and the heated stone at the centre that still dictates the plan, are set out in our history of what a hammam is and where it came from.
The same plan has to survive a very different climate and a very different operating pattern in the Gulf, which is where our page on hammam projects in Dubai picks up: approvals, waterproofing, and the services that have to fit above the ceiling. A hammam is also rarely specified alone. In most of the facilities we build it is the warm pole of a wider thermal suite, and the rooms around it are sequenced at the same time.
Cost
What sets the cost of building a hammam?
A hammam has no single price per square metre, because none of the items below grows in proportion to the floor area. Two hammams of the same size can land on very different budgets because of the basin count and the ceiling shape. We prepare the budget range from the drawings; the build sequence is in our guide on how to build a hammam.
01
Volume, not floor area
The heating load comes from the volume. Two hammams with the same floor area but different ceiling heights need different steam generators, and one step up means a larger generator, panel and supply cable. Send the ceiling height with the floor size.
02
Number of heated surfaces
This item moves the budget most. A hammam heated only by its steam generator and one with a heated platform, seats and floor differ in services and in energy use; every heated surface needs its own circuit and thermostat. In a single villa the heated platform is often enough.
03
Waterproofing
In a wet room the costliest mistake comes from the waterproofing. We apply the liquid membrane in two coats and test it for tightness before the finish goes on; the floor falls to a drain. Saving here looks cheap in the first year and means removing the whole finish when a leak appears.
04
Core: ready-made boards or screed
Seats, backrests and niches can be built from factory-made waterproof cores or laid in screed and brick on site. Ready-made cores cost more as material but reduce the number of joints made on site — and site joints are the most common source of faults. See our wedi wet-room systems.
05
Finish and grout class
Glass mosaic, honed stone, single-block marble and jointless microcement differ widely. The grout decides as much as the tile: a wet room needs at least CG2 WA class grout, and epoxy grout is the upper option.
06
Platform and basin workmanship
Whether the heated platform is carved from a single block or assembled, how many basins there are and how much carving they carry are direct workmanship items. A single block adds material, transport and setting cost, and lasts longer because it has no joints.
07
Ceiling shape
A hammam ceiling is never flat. It is built with a fall or as a vault so that condensation runs to the walls instead of dripping on the guest; a vault costs more in formwork and labour and solves the problem at its source.
08
Ventilation and panel position
A hammam has no return air: it needs its own extract and a corrosion-resistant duct. A control panel that is not rated for the wet room goes outside it, and only the sensor enters. Missed at survey, both items mean opening walls later.
Dimensions
Which dimensions apply to the heated platform and the basins?
Typical values we use in practice; each hammam's dimensions are set by its own made-to-measure manufacture.
| Element | Typical value | Why |
|---|---|---|
| Heated platform surface | 40–45 °C | Unheated marble stays cold even in warm room air |
| Basin top height | 85–90 cm | Height for taking water while seated |
| Basin bowl diameter | 45–60 cm | A smaller bowl splashes |
| Basin bowl depth | 20–25 cm | Enough to fill a bowl; more only holds water |
| Distance between basins | At least 1.20 m | Two guests can sit side by side |
| Basins in a six-person hammam | 2 | One per side of the platform |
| Basin flow | 12–15 l/min | Sized with the hot-water supply |
| Water to the basin | 40–45 °C | Stored hot water is mixed down before it reaches the basin |

Cross-section
What is a hammam wall and heated platform made of?
In a hammam the heat comes from the stone. The order of the layers decides how quickly the stone warms up and how long it holds the heat.
01
Marble finish20–30 mm
The heated platform (göbek taşı) and the seats. Thicker stone warms more slowly but holds the heat longer, so the thickness follows the operating hours.
02
Heating coil16 mm pipe
A water or electric circuit laid under the stone. In hard water it scales and one edge of the stone stays cold, so the manifold is kept accessible.
03
Screed and heat spread50 mm
The layer around the coil that spreads the heat evenly to the surface. Poured too thin, it leaves warm and cold stripes on the stone.
04
Waterproofing2 mm
A continuous membrane under the screed. In a hammam water always reaches the floor, so the membrane is turned up the wall by at least 30 cm.
05
Reinforced concrete slabload-bearing
Heated marble and water load the structure. The load calculation belongs in the architectural design from the start.
Selection table
Which steam generator suits the room: Condair or Nordmann?
Electrode or resistive is decided against the water hardness. The generator stands in a dry, ventilated plant position close to the steam outlet, never inside the room.
| Model | Technology | Capacity | Typical use |
|---|---|---|---|
| Condair Omega | Resistive | 2–20 kg/h | Steam showers, home and small steam rooms |
| Condair Omega Pro | Resistive | On the manufacturer's data sheet | Commercial and large steam rooms |
| Condair Sigma | Electrode | 4–65 kg/h · 7 power steps | Steam rooms and hammams of every size |
| Nordmann AT4D | Electrode | 5–65 kg/h · integrated self-cleaning | Hotels, clubs and spa facilities |
