A commercial sauna is judged on day 500, not day one. So everything here is specified one level up: smoked thermowood that takes intensive use, thick aspen benches on frames that dismantle for maintenance, two heaters sharing the load to hold temperature through peak hours, and double glass doors so guest flow doesn’t drain the heat.

We think about your operations too: LED under every bench tier for guest safety, twin temperature sensors wired to a staff-room control panel, and a scheduled maintenance programme from our team after handover. We deliver this class together with building management — from three-phase load calculations to technical permits.

FAQ

Frequently asked questions

How many hours a day can the 16-person sauna run?

We design this class for 12 operating hours a day. The keys are two load-sharing heaters, commercial-grade materials and scheduled maintenance. After handover our team offers a service contract — heater checks, bench re-tightening and replacement of wear parts.

Does our building need special power?

Two 10.5 kW heaters run on three-phase power — standard in commercial buildings. We start with an audit of your panel: if capacity is there, it only needs a dedicated run and protection; if not, the addition is priced into the quote from day one.

What is the investment for a 16-person sauna?

From IDR 300 million, indicative — the final figure depends heavily on the room and chosen finishes. A detailed quote follows the site survey. The general commercial picture is on the commercial sauna page.
