Padel courts are opening across Surabaya at a pace few other sports have matched, boutique gyms are multiplying through the towers of Pakuwon, and hotels along the Juanda–Sidoarjo corridor are competing on amenities their neighbours cannot match. Across all three segments we see the same pattern: a heat-based recovery space is what keeps a member coming back and a guest booking again.
A sauna built for business is a different category of construction from a sauna built for a family bathroom. It runs from opening to closing, serves dozens of different bodies a day, gets wiped down with disinfectant every evening, and has to stay safe for a first-time visitor who has never sat in a hot room before. That is why our specification — from the density of the timber to the way the controls are wired — follows public-building standards rather than residential ones.
We operate as a commercial sauna contractor in Surabaya under a PT PMA legal entity, with three years spent building heat rooms in Indonesia’s tropical climate. Design, construction, electrical work and after-sales support sit with one team under one contract, so you are not left coordinating three separate vendors on your own site.
Why are Surabaya gyms, spas and padel clubs adding a sauna?
Because a recovery zone earns money rather than just decorating a brochure. A hot session after training loosens muscle, so padel players and gym members show up more often and hold onto memberships longer. A sauna also opens a new revenue line on its own — paid single sessions, monthly add-ons, bundling with personal training, or a post-tournament rate for a club that just hosted a competition. We go through the full arithmetic behind that for gyms and padel clubs in our article on commercial saunas for Surabaya gyms, including how to price a session and structure membership add-ons.
For hotels and spas, a thermal zone works hardest in the low season: a facility that does not depend on the weather and sells easily as part of a staycation package. There is a last factor rarely admitted but very real in Indonesia: the photograph. A glass-walled sauna with hidden LED lighting gets photographed by guests unprompted, and every post becomes free advertising for your facility.
What separates a commercial specification from a home sauna?
- Industrial heaters with reinforced elements and a larger stone load, rated to run up to 16 hours a day without a cooling break.
- High-density wood with no resin pockets and a hygienic finish, so benches do not darken even under nightly disinfection.
- Three-tier benching and a planned guest flow so peak capacity is reached without anyone queuing at the door.
- 8 mm tempered glass, a heater guard rail and intake-exhaust ventilation built to public-space safety rules.
- A centralised control panel with remote monitoring, so reception sets temperature and schedule without leaving the front desk.
- Multi-layer insulation that brings the room to working temperature in 40 minutes and holds heat for hours, keeping the power bill sane.
For licensing and inspection, we hand over material documentation and the installation schematic — fire and sanitation inspections go through without drama, and your business does not stall over a missing certificate.
What formats can we build?
Most projects are a dry Finnish sauna at 70–90°C with 10–20% humidity, the version athletes prefer. On top of that base we vary the concept: an aromatic herbal sauna for a spa, panoramic glass walls for a club chasing a design statement, or an interior built to a hotel’s brand book, down to the timber tone and the lighting sequence. If your concept includes cooling, we integrate a chiller-cooled cold plunge into the same guest-flow design rather than bolting it on afterwards.
How much does a commercial sauna contractor in Surabaya charge?
The figures below are a starting point for your budget. Every project is recalculated against floor area, materials and the condition of the building:
| Type | Indicative price |
|---|---|
| Commercial sauna for gym / spa / hotel | from IDR 150 million |
| 10-person sauna (3.5×2.6 m, 10.5 kW heater) | IDR 190–240 million |
| 12-person sauna (4×3 m, 12 kW heater) | IDR 230–290 million |
| 20-person club sauna (5×3.5 m, 2×10.5 kW) | from IDR 300 million |
| Full contrast therapy zone (sauna + cold plunge + jacuzzi) | from IDR 250 million |
| Spa equipment package (heater, generator, controls) | from IDR 100 million |
All prices above are indicative; we issue the final itemised quote once we have surveyed your site free of charge. The components that move the number most: capacity, interior wood grade, glass area, and how ready the building’s electrical infrastructure already is.
Three-phase power and building readiness
Heaters from 10.5 kW upward need a three-phase connection; an 8 kW unit can still run on an 11,000 VA single-phase supply. At design stage we audit the building’s available capacity, calculate the combined load alongside air conditioning and other equipment, and then support the application to raise supply with PLN where needed — the official PLN fee is the owner’s cost, and we manage the paperwork through to completion. Wiring uses heat-resistant SiHF cable, a dedicated circuit breaker and ELCB protection. Ventilation and drainage routes are planned into the working drawings from the start, not retrofitted once the walls are already up.
Aftercare that keeps your business open
A machine that stops means revenue that stops, and our after-sales support is built around that exact fear. Our original spare-parts warehouse sits inside Indonesia, so a heating element or sensor is replaced without waiting on a shipment from overseas. For an emergency, our technician arrives within hours, not weeks. Before handover, we train your staff on the daily routine — morning heat-up, cleaning, and simple checks. Construction carries a 2-year warranty, the heater carries a 1–2 year factory warranty, and a scheduled service contract is available for facilities running at full capacity. Ongoing needs — from sauna stones to control panels — are covered by our spa equipment supply line.
Where across Greater Surabaya do we build?
Our commercial projects cluster around the city’s fitness and hospitality pockets: gym and club fit-outs in Pakuwon and West Surabaya, boutique hotels and spas in Gubeng and Darmo, staff-wellness facilities inside the SIER industrial estate in Rungkut, hotels along the Juanda airport corridor in Sidoarjo, and corporate facilities inside the JIIPE industrial zone in Gresik. Distance is not an obstacle — material logistics are already accounted for in the quote.
How ordering works
- Send us a WhatsApp brief: business type, location, and your opening timeline.
- Our manager calls you that same day to scope the requirement.
- You share photos or a floor plan of the intended space.
- We carry out a free technical survey anywhere across Greater Surabaya.
- We return a placement visual showing the sauna inside your actual room.
- You sign off on the itemised quote and the build schedule.
- A 50% deposit releases material ordering, and the build begins on schedule.
- We hand over after a joint test heating, and the 2-year construction warranty starts that day.
