Ninety degrees.
Then three.

Indicative starting prices are IDR 52,000,000 (≈ USD 3,200) for an infrared cabin, IDR 78,000,000 (≈ USD 4,800) for a barrel sauna, and IDR 125,000,000 (≈ USD 7,700) for an outdoor cabin sauna. Those cover the room and heater. The full installed cost also depends on foundations, drainage, glass and whether your electrical supply needs upgrading, which is why every quote follows a site survey.

Three to six weeks from signed drawing to first use for a standard barrel or cabin sauna, and eight to twelve weeks for a custom built-in room. An ice bath is faster — usually two to three weeks, unless it needs a new deck or a power run. Lead time is driven mostly by freight to the island and by any electrical supply upgrade, both of which we confirm before you commit.

The full process, stage by stage, is on how we work.

Often, but not always. Many Lombok villas are on a single-phase PLN supply that comfortably runs a small infrared cabin but not a 6 kW-plus stone heater. We check the supply at your board during the survey and tell you plainly whether you need an upgrade or three-phase, and what that costs, before you order anything.

Yes, and we would rather build both together. The hot room and the cold plunge are one system — the distance between them, the drainage, and where you rest afterwards all matter. We build cedar ice baths and fully chilled cold plunges, with the refrigeration sized against Lombok's ambient temperature rather than a European rating.

Our working range is 8–12 °C, with 15 °C a sensible entry point for beginners. Below 5 °C is specialist territory that should be supervised. Colder is not automatically better — time at temperature matters more than chasing a low number. Never use an ice bath alone or after drinking alcohol, and check with a doctor first if you have a cardiovascular condition, blood-pressure issues, or are pregnant.

You can build the box. What people get wrong is the parts you cannot see: the vapour barrier, the ventilation path, and the timber choice. Ventilation designed for a cold dry climate barely moves air at 85% humidity, so the room feels stale rather than hot and rot starts inside the wall. Resinous pine on a bench weeps sap and gets hot enough at the knots to burn. Electrical work must be done by a qualified electrician regardless.

If you want to try, we would rather you did it well — start with tropical sauna ventilation and choosing timber for a tropical sauna. Message us and we will tell you honestly whether your plan works.

Yes. We build across Lombok including Kuta, Senggigi, Mataram, Selong Belanak and Sire and Tanjung, and we install on Gili Trawangan, Gili Air and Gili Meno. Island delivery adds a boat transfer and constrains panel sizes, so we design around it from the start rather than discovering it on delivery day.

What that means in practice is on the Gili Islands page — there are no cars, so everything moves by cart.

Yes. Salt air and humidity mean a coastal sauna needs real maintenance, so every handover includes a written schedule. We offer servicing across the island — stone replacement, bench refinishing, seal and fixing checks, chiller service and water treatment. We also service systems we did not build, once we have inspected them.
