About
The people behind Sauna Batam
We're a PT PMA-registered contractor building saunas, steam rooms and cold plunges, three years into learning exactly what this island's climate does to a cabin. Workshop and spares store both sit in Batam Kota, which is why a survey anywhere on the island books within one to three working days and a service call is measured in hours rather than days. Heaters are Harvia, Sawo and Tylo.

Why we kept the workshop here instead of in Java
Most custom sauna work in this country gets sold out of Jakarta or Surabaya, with a crew that flies in, books a hotel, and bills you for both. On an island, that arrangement costs the client twice over - once in the original quote, and again every time something needs a second look afterwards. We chose the opposite setup: workshop, crew and spares store, all based here in Batam Kota.
It shows up in small, practical ways. A survey out in Nongsa or Sekupang happens this week, not whenever a visiting team next has a slot free. Panels get cut, dry-assembled and corrected on our own floor, so what turns up at your house has effectively already been built once before. And if a controller fails in year two, a technician drives over rather than you waiting on the next sailing out of Jakarta.
The three things this island makes us plan around
Three constraints shape every job here, and we'd rather walk you through them before the deposit than after. Humidity sitting between 73 and 96 per cent means the vapour barrier and ventilation gap aren't optional extras. Sea air means stainless hardware on anything the spray can reach. And domestic supplies of 2,200-5,500 VA mean that, sometimes, the honest recommendation is an infrared cabin instead of the hot room you originally asked about.
Free trade zone status is the one constraint that actually works in your favour. Imported heaters and timber land on Batam without the duty and tax layer that applies across the water, which is how a locally built cabin can carry European hardware without an absurd price tag. What it costs instead is time - four to fourteen days at sea, plus paperwork that has to be correct - and both are already written into the schedule before you ever see a quote.
The people doing the work, and what the warranty actually covers
It's a small, permanent team rather than a rotating cast: a joinery crew based in Batam Kota, one electrician who handles every heater connection personally, a plumber for plunge and steam work, and a single manager who answers WhatsApp and attends every survey. That manager stays attached to your project from the first photo through to the test heat-up, which is exactly why the answers don't shift halfway through.
Warranty runs two years on structure and installation, and the heater carries its own separate factory cover of one to two years on top of that. Spares stay on the shelf here rather than on order elsewhere. Every price is indicative until the survey, then fixed in the itemised quote that follows; ranges are public on the pricing page, or you can skip straight to booking a survey.
Snap three photos and we will text back a ballpark figure
Doesn't matter if it is a Nongsa villa, a Nagoya health club or a bare room in a Sukajadi cluster house - three photos plus your VA rating gets you a first number.
