Ferry-close to Singapore - built and fitted from Batam Kota
Sauna and ice bath builder in Batam, with our own island workshop
Dry saunas, infrared rooms, steam rooms and chilled plunges, built in Batam Kota by a crew with three years on this island and more than 100 finished projects behind it. The survey is free and the quote already carries sea freight and FTZ paperwork, so the price you sign is the price you pay.
Free survey anywhere on the island · quotes include sea freight and FTZ paperwork · 2-year structural warranty · Price tables
Households on the island, resort operators and expatriate managers run their whole project with us in English, start to finish. We design, build and fit dry cabins, infrared rooms, steam rooms and cold plunges for villas along the Nongsa coast, hotel health clubs in Nagoya and cluster houses in Batam Centre. Indicative IDR 15-300 million, anywhere from a single day to eight weeks.
Products
Six formats, one workshop in Batam Kota
Start at IDR 15 million for a prefab box, or go all the way to a commercial installation for a hotel or gym with a cold plunge standing next to it.

Dry sauna
Timber-lined room running 70-90 degrees off a 3.6-9 kW heater, sized to fit the space you have instead of a fixed factory template.
IDR 60-120 million
Villa luxury sauna
Thermowood-and-glass cabin built for a pool deck, framed so the outlook stays open while the sea air stays outside.
IDR 80-150 million
Prefab sauna cabin
Ready-built two-person unit from the workshop - carried in, wired and heating within the day, and just as easy to relocate later.
IDR 15-35 million
Infrared sauna
Carbon-panel room for one or two at 45-60 degrees, drawing only 2,200-5,500 VA and finished inside a single day.
IDR 30-70 million
Steam room
Fully tanked and tiled room near full humidity at 40-45 degrees, a 6-9 kW generator paired with a sloped ceiling to manage the condensation.
IDR 50-100 million
Ice bath
Timber tub and chiller pulling 30-degree tap water down to single digits, holding it there without another bag of ice ever again.
IDR 45-90 millionHere, cold sells the room before heat does
The thermometer on Batam barely moves - 24 to 35 degrees whatever the month, humidity parked between 73 and 96 per cent, and tap water arriving already close to body temperature at around 30. Nobody on this island is short of warmth, so the thing that actually sells itself is eight to twelve degrees of cold: after a lap along Coastarina, after the gym in Batam Centre, or before the queue for the last ferry back. The hot room keeps its place too, just later in the evening - a short sit at 80 degrees, straight into cold water, then bed.
No other Indonesian market sits this close to a first-world ferry terminal. Boats from Singapore land at Batam Centre, Sekupang and Harbour Bay in 45 to 70 minutes, and the Tanah Merah run into Nongsapura is over almost as soon as it starts. Weekend guests step off that boat with a health club back home in mind - hot room, steam, something cold to finish in - and villas on the Nongsa coast or resorts out past Barelang that can offer all three simply charge more for the weekend, because guests notice when it is missing.
The housing stock sorts into a handful of types, and each one sets the brief. Pool villas in Nongsa carry 11,000 VA or three-phase power and rarely need a workaround. Two-storey cluster houses in Batam Centre, Sukajadi and Orchard Park sit lower, at 2,200-5,500 VA. Towers in Nagoya and Jodoh add a lift booking and loading-hours rule to every delivery. Older Tiban and Sekupang houses usually have the room but not the amperage. What evens the odds is free trade zone status: a Harvia heater or a stack of red cedar lands here without the duty that applies across the water in Java, so on Batam the hardware is rarely the constraint - the electrics and the access usually are.
Four things that decide whether a cabin lasts on this island
Lining board first, then 50 mm of rockwool, a taped foil vapour barrier over every seam, a 20 mm air gap, and cedar cladding last. Leave out the foil or close up that gap and the island's humidity finds its way in - mould shows up within two or three years, not ten.
Standard screws corrode fast this close to the strait. Anything built near the coast gets stainless hinges, brackets and fixings, an outdoor cabin gets a roof against sun and driving rain, and a plunge chiller is sited in shade where its condenser can actually breathe.
A 6-9 kW heater calls for 7,700-11,000 VA, which means most 2,200-5,500 VA houses need a tier upgrade first. Our part is the heat-resistant SiHF cable, a dedicated breaker and an ELCB; the upgrade itself is billed by PLN Batam directly to the owner.
Harvia, Sawo and Tylo, each carrying one to two years of factory cover. Elements, stones and controller boards sit on our own shelves in Batam Kota, so a repair is a same-week visit rather than a wait for the next cargo sailing.
Areas
Five zones, five different jobs
Nongsa's coastal villas, hotel work in Nagoya and Jodoh, cluster houses across Batam Centre and Sukajadi, older housing stock in Sekupang and Tiban, and resorts strung along the Barelang bridges - five very different briefs under one roof.

From the first WhatsApp message to the first heat-up
Eight steps cover every job on the island, a villa deck in Nongsa or a spare room in Batu Aji alike, and nothing is charged until you have approved the quote.
Tell us the district or estate and roughly what you want built. Expect a callback the same day, in English if that suits you better.
Three to five images of the space plus a shot of the consumer unit. That is usually all we need for a first indicative range.
One to three working days out, wherever you are on the island - Nongsa, Nagoya, Batam Centre, Sekupang or Batu Aji.
You see the finished cabin rendered into your own space, and a quote broken down item by item with the sea-freight wait already factored in.
Signing off the quote is what triggers the heater and timber order and reserves your build slot in the workshop.
Panels, aspen or abachi benches, frames and any plunge tub are assembled once in the workshop before a single piece leaves for site.
A single day on site for an infrared cabin, up to eight weeks for a commercial job, wiring, ventilation and tanking all included.
We bring the cabin up to temperature with you present, check the humidity and the ELCB, and hand over paperwork covering two years on the structure.
Frequently asked questions
We split time between Singapore and the villa in Nongsa - does the sauna need attention while it sits empty?
Mostly it looks after itself. Vents stay open front and back so the cabin cavity keeps drying between visits, and we leave the door slightly ajar on handover rather than sealed shut. A caretaker only needs to glance at it; full attention starts again when you do.
Is the finish actually close to what we've used in a Singapore condo gym?
That is the benchmark most villa clients name, and it is achievable: tempered glass, thermowood, stainless fixings and a proper heater brand rather than a generic one. What differs is the supply chain behind it, which is why we build to order in our Batam Kota workshop instead of shipping a finished box in.
Our unit in a new Sukajadi cluster is wired for 5,500 VA only - what actually fits?
A two-person prefab cabin at 3.6 kW sits comfortably inside that, and so does an infrared cabin at a fraction of the draw. A four-person room with a 6 kW heater is where most cluster meters need PLN Batam to step them up, and we confirm that at survey rather than guessing from a spec sheet.
A resort we manage on Barelang wants a wellness corner ready before the next season - how fast is that realistically?
Four to eight weeks once the deposit clears, because panels and benches are built off site in our workshop rather than fabricated in your car park. Phasing around bookings is normal for resort work; tell us the blackout dates at survey stage.
The plot is right on the water in Sekupang - does that change how you build?
It changes the hardware and the ventilation, not the layout. Hinges, brackets and fixings go stainless rather than standard, an outdoor cabin gets a roof against driving rain, and the plunge chiller sits in shade with air moving around it.
If the resort runs on a backup generator during an outage, will the heater or chiller keep working?
Generally yes, provided the genset covers the connected load and the supply is stable rather than surging. We ask for the generator's rated output at survey stage for any commercial job, since a heater cycling on a rough handover between mains and backup is the more common complaint.
