A sauna for a Jakarta business club or executive lounge is a 4–8 person unit at commercial spec — a 9–10.5 kW heater on a full duty cycle, mechanical ventilation into the building shaft, full tempered glass for the visual, and benches that can take two hundred guests a week — costing from IDR 150 million with 4–8 weeks of work. What separates it from a gym sauna isn't the size but the context: it stands inside a multi-storey building with management, central air handling, shared three-phase power, and guests who arrive in suits.
Requests like this come from three directions: members' clubs around SCBD and Mega Kuningan adding a "recovery room" beside the cigar bar, family offices and firms building executive lounges for their partners, and boutique hotels renting their club out to city members. As the builder behind compact high-rise units through our Jakarta sauna construction service, here's what we check before drawing anything.
Building approval first, design second
In an office building, four parties have to agree before a sauna goes in: building management, the building's MEP consultant for electrical loads and air handling, the HSE/fire safety team for the smoke sensors that must become heat sensors in the sauna zone, and — if the space is leased — the unit's owner. The documents we prepare for them: placement drawings, electrical loads, ventilation and discharge routes, glass and fire-rated material specs, and a work plan with hours that don't disturb other tenants. This takes 2–4 weeks and runs parallel to the design; skip it and your finished sauna isn't allowed to switch on.
Commercial spec: what changes from a home sauna
| Component | Home sauna | Business club sauna |
|---|---|---|
| Capacity | 2–4 people | 4–8 people, often two bench tiers |
| Heater | 6–9 kW, 2–3 sessions/week | 9–10.5 kW commercial, 8–12 hours/day, 60–100 kg of stone |
| Electrics | 7,700–11,000 VA single-phase | Three-phase from the floor panel, its own run, an ELCB, a separate meter |
| Ventilation | Natural inlet and outlet | Mechanical exhaust into the building shaft, calculated with MEP |
| Materials | Cedar, aspen | High-density thermowood, thick aspen, full 8–10 mm tempered glass |
| Controls | A user panel | A locked staff panel, schedules, temperature logs, building-system integration |
| Indicative cost | IDR 60–120 million | From IDR 150 million; 6–8 people with full glass IDR 220–350 million |
Indicative figures before a survey; the building's electrics and ventilation are often the biggest line after the cabin. Price ranges for every format are in the pricing page.
Layouts that work in a lounge
The most successful pattern: a full-glass sauna along one side of the room as a warm "shop window" visible from the bar or lounge, changing rooms and showers behind it (not in front — guests don't cross the lounge in a towel), and a cool-down seating area between the two. If the club wants contrast therapy, the sauna and ice bath package puts one or two chilled tubs in the same wet room, draining into the nearest plumbing shaft. From the 30th floor up, the weight of a filled tub (±1 tonne) needs the building structure's sign-off.
Daily operations: who handles what
A club sauna comes on before the first member arrives and goes off after the last one leaves — usually 06:00–22:00. A locked panel with schedules removes the dependence on staff to switch it on; temperature logs help when a guest complaint raises questions. Daily bench cleaning with neutral soap, a monthly stone check and a heater service every six months are the routine we write into the operations manual and can run as a service contract. Running costs: a 10 kW heater working 8 hours a day on a thermostat uses roughly 40–50 kWh daily at business rates, plus water and cleaning supplies.
Silence and privacy: the two things members pay for
An executive club sells two things a gym doesn't: silence and privacy. For silence, a fanless electric heater, an exhaust mounted far off and connected through insulated ducting, and a glass door with a magnetic seal that never clangs. For privacy, glass with a frosted gradient to bench height, warm dimmable LED lighting, and private session booking through the club's app. These details separate a sauna that gets used from one photographed once for the brochure.
The project timeline and the first step
The survey and building management meetings in week one, drawings and the quote in week two, building approval running parallel for 2–4 weeks, materials 2–3 weeks after the deposit, 3–5 weeks of installation with noisy work at night or on weekends per the building's rules, then a 24-hour heat test and staff training. 8–12 weeks in total from the first chat. For a per-type budget picture in this city, our what a sauna costs in Jakarta gives you an early calibration before the quote.
The business model: member facility or paid private sessions
The clubs we meet run their saunas on two models. The member facility: the sauna is included in the dues, open through operating hours, and its value is measured in member retention — the sauna becomes the reason to come three times a week instead of one. This model demands 6–8 person capacity and strict cleaning SOPs, because the usage runs high. Paid private sessions: a 4-person cabin booked in 60–90 minute slots for small meetings or couples, at the IDR 400–900K per slot that's standard in South Jakarta. This model suits office lounges and smaller clubs, and a boutique glass sauna with adjustable lighting becomes a product in its own right.
A combination of the two is most common: private sessions morning and evening, open facility in between. A control panel with schedules and logs lets reception staff run it without touching the heater — and the usage numbers from the log are the data you'll want when deciding whether an ice bath earns its place next year.
If you run a club, lounge or office weighing up a sauna, send the floor plan, the building storey and the management contact via WhatsApp. We start with the question that decides everything — what the building allows — before talking timber.
