Sauna Jatinangor: built for a commercial duty cycle
Jatinangor is the university belt, and that decides who buys: gyms, recovery studios and apartment operators rather than villa owners. It means the sauna Jatinangor actually needs is a commercial machine — a continuous-duty heater, a controller with a lockout, and ventilation sized on headcount.
A sauna Jatinangor buys is almost always B2B, not a villa job
Jatinangor is the university belt — ITB, Unpad and IPDN all have campuses here — and that decides who picks up the phone. In villa country the owner calls himself; here it is almost always a gym manager, a recovery studio owner or an apartment operator. The difference is not only who pays. A home sauna runs three hours a week; a gym sauna runs sixteen hours a day, seven days a week, used by people who do not maintain it and have not read the notice on the wall. That is a different machine, not the same one at a higher price.
Commercial duty cycle: what actually changes
Four things. The heater has to be rated for continuous duty, not a domestic unit that happens to be big enough. The controller is commercial: timer, temperature limit and a lockout, so the last session of the night cannot leave the cabin running until morning. The benches have to survive forty people a day, which means mechanical fixings and timber chosen for wear rather than for photographs. And ventilation is sized on occupancy, not room volume — the most expensive mistake we find in commercial installs, because the same cabin with six people in it is a different air problem.
Ice bath for athletes: here is the part nobody sells you
This is the live product in Jatinangor, and a gym owner deserves the full version. Research suggests that cooling straight after strength work can blunt part of the long-term adaptation — reduce it rather than erase it, by an amount still argued over. After endurance work the picture looks different and cold appears far less of a problem. The working rule most coaches use is four to six hours between a lifting session and a cold session. That changes how you schedule the tub, not whether you buy one.
Apartments: infrared, floor loading, lift access
Apartment work in Jatinangor comes with three fixed constraints. Power: infrared at 45–60°C with 1.8–3 kW emitters plugs into a 220V socket, so no PLN upgrade — the same constraint that makes infrared dominate in Cimahi. Floor loading: a tub full of water is a concentrated point load, so we ask about the slab before we quote rather than after. Access: panels have to fit a lift and a corridor turn. At least the access here is flat and predictable — unlike Dago, where narrow uphill roads regularly force a manual carry.
The climate, and how we price it here
Around 700–800 m, 19–21°C at night. For a gym that means the rest zone after a cold session runs on outside air most of the year, saving you an air-conditioned room. But do not expect an easy chiller: the water does not arrive cold the way it does higher up, so a 0.5–1 HP unit works for its living and shows up on the monthly bill. On commercial jobs that number goes in the proposal at the start, because it is what the owner asks about after year one.

Frequently asked questions
How is a gym sauna in Jatinangor different from a home sauna?
The duty cycle. A home sauna runs three hours a week, a gym sauna can run sixteen hours a day — so the heater is continuous-duty, the controller has a timer and a lockout, the benches are built for wear, and ventilation is sized on headcount rather than room volume. Fitting home spec into a commercial room is the most expensive way to save money.
When should gym members use the ice bath — before or after lifting?
Leave four to six hours after a strength session if the goal is building strength; research suggests cooling immediately can blunt part of the adaptation. After endurance work, straight afterwards is fine. Advise members with heart conditions, uncontrolled blood pressure, epilepsy or a pregnancy to talk to a doctor before starting cold exposure.
Can an ice bath go into an apartment in Jatinangor?
Usually, but two things get checked first: floor loading and access. A tub full of water is a concentrated point load, so we ask about the slab before quoting, and the panels have to fit a lift and a corridor turn. For the hot side, an infrared unit at 1.8–3 kW on a 220V socket is almost always the answer, because it demands no PLN upgrade.
Our ice bath will see dozens of people a day — what about the water?
That is the right commercial question. Our standard is 20µm cartridge filtration plus UV or ozone, but at gym volume the water checks and the drain-down schedule become part of daily operations rather than an occasional chore as at home. We hand the schedule over in writing at handover.
