Steam rooms, saunas & spas in Nepal
built so your building
never pays for them

A steam room is a vapor-proof envelope with dedicated ventilation. Built to spec, no moisture leaves the room. The seepage horror stories all come from steam rooms built like bathrooms — tile on brick, no vapor barrier — where the steam finds the structure and stays there. We’ve built the steam rooms at Kathmandu Marriott, Dusit Princess Kathmandu, and Hilton Kathmandu. This is the single most specialist build in a wellness area, which is exactly why five-star properties don’t hand it to a general contractor.

A sauna is timber, heat, and airflow working together. The wood has to be the right species and grade, the heater sized to the room’s volume — not guessed — and the ventilation designed so the heat is even and the timber lasts. We built the sauna at The Pavilions Himalayas that’s still in service after a decade, and the saunas at Marriott, Dusit Princess, and Hilton in Kathmandu. Get the heater and ventilation wrong and you get a sauna that’s too hot at the ceiling, cold at the bench, and hard on the wood.

Some clients want infrared specifically: the lower, deeper heat people choose for recovery and daily use. We specify Tylö infrared panels — the Swedish maker that’s been building saunas in Halmstad for 75 years. We’ve built both kinds in private homes around Kathmandu: a standalone infrared cabin, and a full timber sauna with Tylö panels fitted inside it, for an owner who wanted the traditional sauna and the infrared benefits in one room. Infrared warms the body directly through the panels rather than heating the air, so it runs cooler, draws less power, and is ready when you are.

A jacuzzi runs hot, aerated, and heavily used, so the water chemistry moves far faster than a pool’s. It needs its own dedicated treatment and filtration, not a scaled-down pool setup. Treat it like a small pool and it goes cloudy and scaled within weeks. Built with its own plant, as we did at Kathmandu Marriott, it stays clear and safe through constant use.

A cold plunge holds water at a low set temperature with a dedicated chiller, plus its own filtration and sanitation to stay clean between users. There are two routes: a ready-made unit with chiller, filtration, and sanitation built in, which suits a retrofit or a tight timeline; or a poured RCC plunge — a small deep pool with a chiller on it — which lets you set the size, depth, and finish to match the rest of the wellness area. We’ll tell you which one your space and budget actually call for.

For a hotel, the wellness area is a bookable amenity, not a cost line: a steam-sauna-plunge circuit that keeps working is something guests photograph and pay for. For a home, it’s the difference between a spa you use daily and one that’s always half-broken. Either way, we plan the whole area at design stage so the plant, ventilation, and drainage are right before the walls go up.
