Serving Kota Bogor, Sentul City, Ciawi and the Puncak road
Sauna and cold plunge builder for homes and villas in Bogor Raya
Three years and more than 100 builds across Bogor Raya, from 1970s houses in Sempur to weekend villas above Megamendung. Every cabin gets a foil vapour barrier and a vented cavity, because in a city with 3,500–4,000 mm of rain a year that is what keeps timber clean.

Why a sauna actually makes sense in a rain capital
The nickname kota hujan is not poetic licence — 3,500–4,000 mm of rain lands here most years, humidity sits at 80–90 per cent for months on end, and a properly dry afternoon is the exception rather than the rule. Altitude adds its own layer: about 250 m in Kota Bogor itself, a climb toward 450 m once you reach Sentul City, and 650–800 m by the time you are up at Gadog or Vimala Hills — with Cisarua and Megamendung dropping to 14–21°C after sunset. Against that backdrop, a cabin running at 70–90°C stops being a luxury and becomes the one room in the house that is reliably warm and reliably dry.
Housing varies just as much as the weather. Older properties around Sempur, Taman Kencana and Empang often carry nothing bigger than a 2,200–4,400 VA meter, which usually steers those owners toward a 1.7–2.4 kW infrared unit — or we cost out the PLN upgrade honestly before anyone signs up for a 6 kW heater. Newer clusters, meanwhile, in Bogor Nirwana Residence, Rancamaya and Sentul City tend to carry 5,500–7,700 VA already, enough for a four-person dry cabin with no drama at all. And weekend houses that Jakarta families keep up along the Puncak road almost always want one specific thing: an outdoor cabin under a roof, with a cold plunge parked right next to it.
That humidity is exactly why we will not build the way a dry-climate workshop does. Skip the aluminium vapour barrier and the 20 mm ventilation gap behind the cedar, and Bogor timber grows mould within two or three years — we have personally stripped out cabins barely four wet seasons old. So every wall we build is a sandwich, every cabin gets both supply and exhaust ventilation, and anything sitting in a garden gets a roof over it. The full build-up is laid out on the dry sauna page, and in our article on keeping mould out of a home sauna.
Products
The six builds that cover Bogor Raya
Match the build to three things: the room you've actually got, what your PLN meter allows, and who is going to sit in it — family most weeknights, paying guests some weekends, or a spa's whole clientele.
Dry sauna
Cedar or thermowood, 70–90°C, a vapour-sealed wall built to survive Bogor's damp — sized for two up to eight.
IDR 60–120 million
Villa & glass sauna
A glazed cabin or a roofed outdoor unit that gives a Puncak weekend villa its best listing photo.
IDR 60–120 million
Portable sauna
Pinewood, one or two people, arrives built and is hot the same afternoon — zero renovation required.
IDR 15–35 million
Infrared sauna
45–60°C on an everyday 2,200–4,400 VA meter — the fix for an older house that cannot take a bigger heater.
IDR 30–70 million
Steam room
Mosaic walls, 40–45°C, near-total humidity, waterproofed from the slab to the sloped ceiling above.
IDR 50–100 million
Ice bath
Timber tub, chiller-held between 3 and 15°C — the comedown after a Sentul or Puncak climb.
IDR 45–90 millionSauna Bogor is who Bogor owners call for cold plunges, steam rooms, infrared rooms, portable units, glass villa cabins and dry saunas alike. We stay inside Bogor Raya only, from Rancamaya up to Kota Wisata — nowhere else. A 2×2 m dry cabin runs an indicative IDR 60–120 million and takes 2–4 weeks to fit once the free survey is done.
From your first WhatsApp to the first test heat
It plays out the same way whether you are in a 2,200 VA house in Tajur or an 11,000 VA villa up in Megamendung — the only thing that changes is the drive.
Tell us roughly where you are and what you're picturing — expect a reply inside 1–2 working hours, whether you write in English or Indonesian.
Our project manager gets in touch that day to talk through the room itself, what's printed on your meter, and whether this sauna serves family or paying guests.
A few pictures of the corner, terrace or garden let us catch the obvious deal-breakers before anyone makes the drive out to see it.
We measure on site at no cost, anywhere in Bogor Raya. Visits up the Puncak road are always booked on weekdays, clear of the one-way system.
You get a proper look at the cabin sitting in your actual room — where the benches land, how the glass reads, which way the door swings, and where each vent grille ends up.
You get an RAB itemised line by line, plus a schedule we agree together — nothing gets cut in the workshop before you've signed off.
The tempered glass door, the benches and every sandwich panel take shape in our Bogor Selatan workshop first; what's left is due only once installation starts.
We fit the cabin, then heat it together — temperature, airflow, the heater guard, day-to-day care — and hand over with the two-year structural warranty.
Areas
Bogor Raya, south to north: where we actually work
We cover the whole span from Kota Bogor and Sentul City, up through Cisarua and Megamendung on the Puncak road, across to Ciawi, Gadog and Vimala Hills, with Gunung Putri and Kota Wisata marking the outer edge of our territory. Each area's own page spells out what your PLN meter will need, how the road access works, and which product tends to make the most sense there.
Building for 90 per cent humidity, not against it
Panel, 50 mm rockwool, an aluminium foil vapour barrier, a 20 mm air gap, then cedar. Vapour never gets near the insulation, and the cladding still gets to dry out between sessions.
Cool air comes in low, right beside the heater; the moisture that builds up escapes through an extract fan on the far wall. The cabin dries out in minutes rather than hours afterward — which, in this climate, is really the whole game.
Harvia, Sawo or Tylö — a guard rail comes standard, alongside heat-resistant SiHF cable, an ELCB on the circuit, its own breaker, and 1–2 years of maker’s cover before spares even become a question.
Western red cedar, Scandinavian spruce or thermowood on the inside, aspen or abachi for benches, and ulin or bengkirai reserved for outdoor decking that actually has to take the rain.

Frequently asked questions
What does a home sauna in Bogor actually cost?
In round numbers: IDR 60–120 million gets you a 2×2 m dry cabin, custom-built for four, IDR 40 million upward covers an economy build in mixed materials, a delivered-and-fitted portable unit sits at IDR 15–35 million, and an infrared unit for one or two comes to IDR 30–70 million. Every model’s exact range is broken down on the sauna price page.
How do you keep an outdoor cabin standing up to Bogor's rain?
With a deep roof overhang, a raised deck, and stainless fixings as standard — Bogor rain arrives sideways as often as it falls straight down. Every outdoor build gets the same five-layer wall as an indoor cabin, plus a larger extract fan above 650 m where cloud can sit on the ridge for days.
My meter in Kota Bogor only gives me 2,200 VA — can I still get a sauna?
Two honest options here. Go infrared and you draw just 1.7–2.4 kW, which any 2,200–4,400 VA meter handles with zero changes. Want the full 6–9 kW dry-sauna heater instead? Then a PLN capacity upgrade has to happen first, taking your supply to 7,700–11,000 VA — a cost the homeowner covers, worked out for you up front rather than sprung on you afterward.
Will timber actually survive this climate without going mouldy?
Skip proper waterproofing and yes — a cabin here can smell of damp within two or three wet seasons. We build against that from day one: cedar or thermowood cladding sits over its own air gap, backed by rockwool and an aluminium vapour barrier, with a fan pulling air through before and after every session. Cracking the door open afterward, and running that fan for 10–15 minutes, does the rest.
What's an ice bath, and who buys one around here?
A chilled timber tub, held anywhere between 3 and 15°C. Around here it is mostly Sentul and Puncak climbers cooling down after a ride, plus Gunung Putri families and villa owners chasing that full hot-then-cold combination for their guests. More detail on the cold plunge page.
Does a sauna genuinely help a weekend villa rent out better?
It has become one of the few things guests search listings for by name, right alongside pool and view. A lit cabin on the terrace photographs well after dark, and pairing it with a cold plunge gives a rental an edge over identical villas further down the same road.
