Can I install an indoor sauna in any room of my home?

In most cases, the sauna can be installed in any room, but there are some situations where this may not be suitable without proper consideration. The key factors to think about are ventilation, space, flooring, and electrical access. Good ventilation is essential to prevent excess humidity and moisture buildup.

In terms of space, your chosen room should accommodate the sauna’s size with extra clearance for access and safety. Flooring should be waterproof and heat-resistant; tiles or sealed concrete work best, while carpet or laminate should be avoided. You’ll also need appropriate electrical access, electric heaters typically require dedicated power supplies, which will need to be installed by a qualified electrician. 

Popular locations include basements, large bathrooms, utility rooms, or converted wellness spaces. With the right preparation, a prefab sauna can be a seamless addition to your home, bringing all the wellness benefits of heat therapy into your everyday routine.

How do I maintain or clean my luxury home sauna?

Maintaining and cleaning your prefab sauna is key to preserving its appearance, performance, and hygiene. After each sauna session, allow the space to cool and air out by opening the glass door or venting the room. Wipe down benches and walls with a damp cloth to remove sweat and residue. Avoid harsh chemicals, use mild, non-abrasive cleaner products like our sauna wood cleaner suited for all sauna timber types. 

To help with maintaining your sauna, all sessions should use a towel to sit and/or lie down on, which helps with hygiene and minimises the need for cleaning. Also, the use of sauna seat covers does the same job. For optical upkeep, on a weekly basis, remove any portable steam accessories like steam sauna diffusers or buckets to clean them thoroughly with warm water. Vacuum or sweep the floor regularly to avoid dirt buildup. Keeping your home sauna clean ensures better relaxation, heat therapy, and a longer lifespan for your investment.

For expert support and advice, Finnmark offers professional maintenance services tailored to all indoor sauna models and has a complete sauna cleaning guide to help with all your cleaning needs.
