What is a kaplıca, and how is it different from a hammam?
A kaplıca is built around hot water that comes from underground; a hammam is built around water that is heated for bathing. The difference shows first in where the water comes from, and then in the floor plan.
The Ministry of Health's Kaplıcalar Yönetmeliği (first published in the Official Gazette on 24 July 2001; the current consolidated text is on mevzuat.gov.tr) sets out the definition in Article 4, as amended on 16 April 2010. A kaplıca is a facility where "natural thermal water or thermo-mineral water settings are offered to the public" (our translation). Article 5 lists the kaplıca facility separately, as one built around the nature of the water used and containing a thermal pool and individual bath cubicles. The weight of the definition is on the water source: the setting is tied to water that comes out of the ground warm or mineral-rich.
For hammams, the TDV Encyclopedia of Islam entry "Hamam" by Semavi Eyice gives the framework. The word comes from an Arabic root meaning "to heat; to be hot", its dictionary sense is "a place that heats", and the entry describes a hammam as "a facility made for people to wash by heating water" (our translation). The entry "Hamam" by Zafer Buzcu in the Online Turkey Tourism Encyclopedia (Türkiye Turizm Ansiklopedisi) says much the same: the general name for places of a particular design and layout where water is heated, cold water is also available, and people go to wash.
The same Eyice entry adds that buildings using naturally emerging water with dissolved minerals are sometimes also called hammams, but in Turkish they are known as kaplıca, or ılıca because the water is often naturally warm. So everyday speech blurs the two words, but at the level of the encyclopedia they are two separate concepts.
A short comparison:
| Kaplıca | Hammam | |
|---|---|---|
| Water | Comes out naturally hot or mineral-rich | Heated outside the bathing area |
| Centrepiece | A large pool | The göbek taşı (central platform) |
| Heating | No külhan (furnace room) needed | Külhan (the heating section) |
| Basis of the definition | Kaplıcalar Yönetmeliği | Encyclopedias and tourism literature |
Why is a kaplıca laid out differently from a hammam?
A kaplıca is planned on the assumption that water arrives from the spring already hot. It therefore needs no heating system like a hammam's, and a large pool takes the place of the central platform.
The TDV Encyclopedia of Islam entry "Kaplıca" by Enis Karakaya describes this difference in architectural terms. According to the entry, kaplıcas are buildings that differ from hammams in both function and architecture. Where hammams have a göbek taşı, kaplıcas have a large pool, reached down a few steps and roughly a person's height in depth. The entry also notes that these buildings need no külhan to heat the bathing water: water that generally arrives from the spring at 70-80 °C is cooled down in the basins and pools before use.
The hammam works differently. According to the Eyice entry, in Turkish baths without a pool (that is, those other than kaplıcas and ılıcas), bathers wash by pouring water from a basin (kurna). Instead of a separate closed room for sweating, a raised platform called the göbek taşı is placed in the middle of each heat section. The Turkey Tourism Encyclopedia describes the inner layout of a Turkish bath in five parts: the changing room, the aralık (passage), the soğukluk (cool room, also called ılıklık), the sıcaklık (hot room), and the külhan, the heating section. The introduction page of the Istanbul II. Bayezid Turkish Bath Culture Museum on the Ministry of Culture and Tourism's Turkish Museums portal gives an example: it lists the changing room, warm room and hot room of a double hammam, with the furnace room running along the back and shared water tanks.
What makes this interesting is that the two building types are separate yet have influenced each other. The Karakaya entry says that washing with water running from a spout into basins is also observed in kaplıcas, and that their changing and warm rooms follow the plan of Turkish bath architecture. Some old kaplıca buildings in Anatolia were turned into double hammams. In short, it is not always easy to tell from a domed building whether it is a kaplıca or a hammam; what decides it is the source of the water and what the building is for.
For the cultural side of the hammam, see our Turkish bath glossary; for the difference between a historic hammam and a hotel hammam, see our Turkish bath in Istanbul guide.
What does "thermal" mean, and is a thermal facility the same as a kaplıca?
In everyday speech "thermal" means anything to do with hot water. Legally, it depends on geothermal-resource legislation and on the permit the facility holds. So not every place that says "thermal hotel" offers the same thing.
Article 3 of Law No. 5686 on Geothermal Resources and Natural Mineral Waters defines two separate concepts. Geothermal resources are the waters, steam and gases that emerge or are brought up naturally, whose temperature, owing to the geological structure and the heat of the earth's crust, is continuously above the regional annual average atmospheric temperature, and which may contain more dissolved matter and gas than surrounding waters. Natural mineral waters are cold and hot natural waters formed at various depths of the earth's crust and defined by their mineral content and other components.
Article 17 of the Law matters for tourism. In culture and tourism protection and development regions and in tourism centres, operating permits for thermal tourism purposes are based on the investment areas set by zoning plans and on the capacity of the businesses. No operating permit can be issued in areas used for thermal tourism without a zoning plan, and the authority must first obtain the Ministry of Culture and Tourism's approval for the activities. In other words, being a thermal facility is not a name a hotel gives itself; it is a status tied to a source, a plan and a permit.
The Ministry of Culture and Tourism's definition of thermal tourism is quoted in the Çermik Thermal Tourism Report (June 2012) by the Karacadağ Development Agency, citing a 2012 Ministry source. According to that report, the Ministry describes thermal tourism as a kind of tourism that arises, alongside "various methods such as thermo-mineral water baths, drinking, inhalation and mud baths", from "cure (treatment) applications as well as the use of thermal waters for entertainment and recreation" (our translation of the Turkish report; the quoted phrases are from the report). This sentence is only a definition. It does not show which of those practices any particular facility offers, nor does it promise any result. This guide makes no such claim for any facility.
The practical upshot is that "thermal" is a very broad search term. The page you land on may describe a kaplıca business, a hotel that uses kaplıca water, or simply a spa that has "thermal" in its name. The way to tell which is to ask the questions below.
Is a hotel spa a kaplıca? What does each type of facility offer?
No. A hotel spa does not have to be a kaplıca. A hotel spa is a business inside a hotel offering services such as a hammam, sauna, pool and massage, and it may make no separate claim about its water source.
The table below compares facility types in general. It does not point to any specific business or brand.
| Facility type | Water source | Typical areas | Documents |
|---|---|---|---|
| Kaplıca facility | Natural thermal or mineral water | Thermal pool, individual bath cubicles | Ministry of Health legislation, facility and operating permit |
| Thermal hotel | A hotel that uses kaplıca water | Accommodation, pool, kaplıca section | Tourism licence, thermal-use permit |
| Hotel spa | Heated water (no source claim needed) | Hammam, sauna, pool, massage rooms | Business licence, health requirements for the pool |
| Hammam | Water heated outside the bathing area | Hot room, göbek taşı, basins | Business licence |
The "documents" column is a general outline. The full list of documents for any facility varies with its type and location. For a kaplıca or thermal hotel, the real assurance is to ask the business for the document itself and check it on the relevant authority's website; this guide makes no claim about the licence status of any facility.
Article 14 of the Kaplıcalar Yönetmeliği (as amended on 14 November 2012) requires kaplıca and thalassotherapy facilities to employ a specialist physician and full-time health staff trained to at least high-school level in health, and Article 21 lists the analysis report on the natural element among the documents required for a facility permit. This provision is a good example of the operating difference between a facility certified as a kaplıca and a hotel spa. A hotel spa offers massage, hammam and pool services, and it would not be right to describe it as if it were certified as a kaplıca.
Knowing this lets you choose with your eyes open. If you want a kaplıca setting, look for a facility certified as a kaplıca. If you want a quiet evening of hammam, sauna and massage inside a hotel, look for a hotel spa.
Is there geothermal water in Sapanca?
There is a public municipal news item about geothermal exploration in Sapanca. Its current status was not known when this guide was written.
A news item dated 13 February 2017 on the website of Sakarya Metropolitan Municipality reports that, as part of SASKİ's geothermal exploration work, geothermal water was reached at a depth of 1,180 metres at Uzunkum in Sapanca. It mentions an expected temperature of a little over 40 degrees and an expected flow of more than 10 litres, and officials said the water's suitability for tourism would be assessed after the necessary tests. This is a news report. It does not show that a new facility has opened, that the water is in use, or that any business has been connected to this source. We do not know what has happened since the report, and we make no assumptions.
What this means for you: a news report about a geothermal source in Sapanca does not mean "every hotel in Sapanca is thermal". Use of a resource covered by Law No. 5686 enters a facility's service only after it has been through the licensing and permit process. A hotel saying it is thermal does not by itself show that this process has been completed; ask for the document and ask the business what kind of use it means.
The lake, shoreline and climate of Sapanca are a separate matter; see our guides to Sapanca in winter and the weekend getaway from Istanbul to Sapanca.
What should you ask when searching for a "thermal hotel in Sapanca"?
Eight simple questions are enough to tell what a facility in your search results actually is. It is best to get the answers from the facility itself, in writing or on WhatsApp.
This list is not for judging any business. It is meant to firm up your own decision.
- Where does the water come from? Does the facility take its water from a natural source, or does it heat its water? The answer largely settles whether it is a kaplıca or a hotel spa.
- Which documents does it hold? A facility and operating permit may be asked for from a kaplıca, a tourism licence from a hotel. Showing a document is an easy thing for a facility to do.
- What kind of pool is it? The Ministry of Health's Regulation on Health Requirements for Swimming Pools applies to swimming pools. The Ministry's Pool Waters page says pool water temperature, pH and free chlorine values must be posted on a board that users can see. You can ask for these values or read them on the board.
- What are the entry conditions? Do only hotel guests come in, or are outside visitors accepted too? For Beatus Spa Sapanca, this is something to get from the location; this guide makes no claim about entry conditions.
- Are women and men separated? Are the hammam and the pool separate for women and men, shared, or divided by time slot?
- What are the hours and the last appointment? Spa hours and the last appointment time can vary by location; write to the location for current information.
- What is provided? Items such as a peştemal (wrap), towel, slippers and cap vary from one facility to another.
- How do you book? A booking engine, the phone or WhatsApp? At Beatus Spa locations, reservations are made by WhatsApp and phone.
One thing to add to the eighth point: if you have a health question, settle it by talking to your doctor, not in a booking message. Share with the facility only as much as you think necessary, in person with the specialist.
What is a hotel hammam and sauna experience like?
A hotel hammam is the traditional ritual of washing at a basin in a hot domed space, with a scrub and foam, adapted to hotel comfort. A sauna is a dry, hot room.
The details of that distinction are in our guide to sauna, steam room and hammam differences. Here we stress only the point a reader expecting a kaplıca needs: looking for a "pool" in a hotel hammam would be a misreading of what a hammam is. As the Eyice entry says, having no pool is the Turkish bath's own layout: you wash by pouring water at the basin, and the göbek taşı is the place for sweating.
For the scrub and foam steps of the hammam ritual, see our scrub and foam massage guide. A hotel hammam is an area inside the hotel property; this fact sets your expectations, but it does not answer the question "which hammam should I go to?"
In what order do you use the pool, sauna and hammam?
There is no fixed rule. Many people warm up in the hammam first, then rest and move on to the pool. What matters is giving your body time between each step.
When a hotel spa has all three areas side by side, a general framework helps. After a hot area, it is sensible, for both comfort and safety, to cool down, drink plenty of water and rest before moving on to the next step. For an example of how the order of hammam, outdoor pool and massage can be thought through in Sapanca, see our Sapanca hammam guide; for pool use, we also have a hotel pool etiquette guide.
What should you know about safety with hot water and saunas?
The general safety rules are simple: stay short, rest, drink water, and leave if you do not feel well. If you have a question about your health, ask your doctor first.
Common-sense rules for hot areas: do not enter a hot area if you have had alcohol; keep your time in the heat short; cool down gradually afterwards; drink water in between; do not use a hot area on a day when you feel unwell; and leave straight away if you feel unwell. This is a general checklist, not medical advice. Talk to your doctor about how long to stay and whether a hot area is suitable for you given your health. The same common sense applies to a sauna, a hammam and a kaplıca: stay short, drink water and listen to your body.
A kaplıca or thermal facility may have additional rules. Those facilities ask you to follow the guidance of their own specialists; for what to do and what not to do, ask the facility's staff and your doctor. This guide gives no recommendations on that.
What is and is not at Beatus Spa Sapanca?
Beatus Spa Sapanca is a hotel spa on the ground floor of a separate building in the garden of the Wellwood Sapanca hotel. It is not a kaplıca or a thermal facility.
Giving you this information is part of setting the right expectations. According to the information the company has confirmed, the location offers:
- Separate Turkish baths for women and men, with steam, foam and scrub steps in the hammam.
- A sauna.
- An outdoor pool, usable from June to the end of September.
- A VIP room for two people, usable by a family of up to five, with a shower, toilet, sauna, steam room, jacuzzi and hammam in the room.
- One couples' massage room.
- A peştemal and towel are provided; a cap is not required.
- The location opened in January 2026.
For anything not on this list we make no assumptions: for matters such as an indoor pool, a separate steam room, entry conditions and age policy, get current information from the location. We also make no claim about the water source of the hammam; in the sense of the TDV Encyclopedia of Islam's definition, a hammam is a building where you wash with heated water.
For the location's details, see the page for our Wellwood location in Sapanca. Reservations are made by WhatsApp and phone; the numbers are on the contact card on that page.
