This is our answer to the question we hear most from Surabaya apartment owners: “my unit at Pakuwon City is only 45 sqm — will it still fit?” It will. The cabin uses light pinewood so a tight room still feels open, a single-tier aspen bench that never scorches skin, and a full 8 mm tempered-glass door so it does not read as a sealed box from inside.

Look closely at the gallery: the glass-door hinge and handle are fitted with real precision, and the aspen bench joints are sanded smooth with no rough grain. At this size, a 2 mm gap in the joinery would be obvious — which is why compact builds get more scrutiny from us, not less. It suits a second bathroom in Gubeng, an apartment unit in Pakuwon, or a small rented house near campus in Dharmahusada.

FAQ

Frequently asked questions

Is 5,500 VA really enough for an apartment sauna?

Yes — the 3.6 kW heater in this format is sized for 5,500 VA homes, wired with its own breaker and ELCB. In Surabaya apartments with per-unit metering this is usually enough without an upgrade. If your unit sits at 2,200–3,500 VA, we calculate peak load first during the free survey.

What is the smallest room this fits?

Allow 1.7 × 1.4 m and you are safe: the 1.5 × 1.2 m cabin plus service clearance. Minimum ceiling height is 2.3 m. A second bathroom, a laundry corner, or a small storeroom are the most common spots we use in Surabaya homes and apartments.

How much does a 2-person sauna cost installed in Surabaya?

Indicatively IDR 55–70 million installed: pinewood cabin, Harvia 3.6 kW heater, safe wiring, and a test heat-up. The final itemised quote follows the free survey — the cost breakdown is in our Surabaya sauna cost guide.
