04 · Why us
Six things we do differently
2-year construction warranty
Plus a 1–2 year manufacturer warranty on the heater. We come back if something goes wrong — we don't vanish after handover.
Imported heaters with real warranties
Harvia (Finland), Sawo, Tylo — with spare parts available, not an unbranded heater that can't be serviced.
A registered PT PMA company
Clear contract, written cost breakdown, staged payment with a 50% deposit. Three years building saunas and cold plunges in Indonesia.
Free visualization from your photo
Send a photo of your room or garden on WhatsApp — we'll draw how the sauna or cold plunge will sit there, free, before you pay a rupiah. No guessing from a catalogue.
Serving all of Tangerang Raya
From BSD City to Bintaro. We plan and quote over photos and chat — then install on site at your place.
Electrical done right
Heat-resistant SiHF cable, a dedicated breaker and an ELCB. We help arrange a PLN power upgrade when it's needed.

05 · How it's built
A five-layer wall — why our saunas don't grow mould
Tangerang humidity averages 80%. A sauna built like a wooden wardrobe traps moisture in its walls — and grows mould within 2–3 years. We build a sandwich:
- Structural panel
- 50 mm rockwool
- Aluminium foil — vapour barrier
- 20 mm ventilation gap
- Cedar / thermowood boards
Imported interior wood: western red cedar, spruce, thermowood; aspen/abachi benches that stay cool on the skin. Dense local hardwoods — for outdoor decking only.

06 · Electrical
Our first question: what's your home's VA rating?
A 6–9 kW heater needs 7,700–11,000 VA — while older homes in Karawaci or Ciputat often still run 2,200 VA. We check your panel from a photo, help arrange a PLN upgrade, or offer an infrared unit at 1.7–2.4 kW when an upgrade isn't possible.
- Heat-resistant SiHF cable — not ordinary PVC
- A dedicated breaker + ELCB on every install
- Power upgrades: official PLN tariff, we handle the paperwork

Frequently asked questions
How much does a sauna cost in Tangerang?
A custom 2×2 m dry sauna for four runs Rp 60–120 million installed; a budget build starts at Rp 40 million, infrared Rp 30–70 million. These are indicative — the final costing comes after you send a photo of the spot. Full detail on the pricing page.
How much is a cold plunge with a chiller?
A timber tub with a stainless liner plus a ½–1 HP chiller runs Rp 45–90 million; the chiller alone is Rp 25–55 million. It holds 3–15°C in the Tangerang climate. Details on the cold plunge page.
Is my home's electricity enough for a sauna?
A 6–9 kW heater needs 7,700–11,000 VA, while many older Tangerang homes still run 2,200–5,500 VA. The fix is a PLN power upgrade (we help arrange it) or an infrared unit at 1.7–2.4 kW. The full maths is in sauna power requirements.
How long does a sauna take to install?
A custom home sauna is 2–4 weeks of work plus 1–2 weeks for material delivery. Infrared is 1–2 days, a steam room 3–5 weeks, a cold plunge 1–2 weeks, and commercial projects 4–8 weeks.
What's the difference between a sauna and a steam room?
A dry sauna runs 70–90°C at 10–20% humidity; a steam room is 40–45°C at nearly 100%. The feel, the upkeep and the cost all differ — full comparison in sauna vs steam room.
Can I build a sauna myself?
You can — some of the work is genuinely DIY-friendly. But there are critical points: the vapour barrier, ventilation and electrics. We wrote an honest guide, building a sauna yourself, including when to call a contractor.
Which areas do you cover in Tangerang?
All of Tangerang Raya: BSD City, Gading Serpong, Alam Sutera, Lippo Karawaci, Bintaro Jaya, Serpong, Ciputat, Pamulang, Cipondoh, Citra Raya, out to the West Jakarta border. Just send a photo — the visualization is still free. See the contact page.
Is there a warranty?
Yes. A 2-year construction warranty from us, plus a 1–2 year manufacturer warranty on the heater (Harvia, Sawo, Tylo). Handover always includes a heat-up test together.
