What is a home sauna?

A home sauna is a small, enclosed room designed to produce elevated temperatures and often increased humidity for short sessions. Traditional saunas use heated rocks or a wood stove to warm the air, while infrared units heat the body directly with radiant energy. Residential saunas vary in size from single-person cabins to multi-person rooms and can be custom-built or prefabricated modules. Materials typically include softwoods like cedar or hemlock that tolerate heat and moisture while resisting warping.

Planning a sauna in your home

Location and planning affect comfort, ventilation, and safety. Popular placements include basements, bathrooms, garages, and dedicated hobby rooms; proximity to a shower or changing area is practical. Ensure the chosen space can handle heat, humidity, and electrical or chimney requirements. Consider floor support for heavier installations, moisture-resistant flooring, and adequate room for insulation and vapor barriers. Local building codes and permits may apply, and consulting a licensed contractor or local services in your area is recommended to confirm compliance.

How do saunas generate heat?

Saunas generate heat in two main ways: by heating air inside the room (convection) or by using infrared radiation to warm skin and objects (radiant heat). Traditional electric heaters or wood stoves heat stones that release warmth into the surrounding air; pouring water on the stones raises humidity and produces the characteristic “steam” known as löyly in Finnish practice. Infrared panels emit specific wavelengths that penetrate the skin more directly, producing warmth without the same level of ambient heat. Each approach creates different sensations and requires different ventilation and control strategies.

Wood saunas: features and considerations

Wood-burning saunas are valued for their aesthetic and the tactile quality of heat produced by heated stones and a stove. They often require a non-combustible hearth, safe clearances, and a properly installed chimney to vent smoke and combustion gases. Wood models can operate without electricity, which may be useful in remote locations, but they need routine maintenance: chimney inspection, ash removal, and secure wood storage. Choose proper lumber and hardware designed for sauna use, and follow safety protocols for stove operation and ember containment. Local regulations may control wood-burning appliances in residential settings.

Infrared saunas: how they differ

Infrared saunas use electric panels that emit near- or mid-infrared wavelengths to warm the body directly. They typically reach target sensations at lower air temperatures than traditional saunas, which some users find more tolerable. Installation is often simpler for infrared cabins—lighter ventilation and no chimney—but they require safe electrical supply and correctly rated circuit breakers. Materials should resist prolonged radiant heat exposure, and panel placement matters for even heating. Infrared systems are electric-only and do not produce steam unless combined with external humidity sources.

Safety, maintenance, and choosing local services

Safety and maintenance are central to long-term enjoyment. Ensure smoke and CO detectors are installed where applicable, provide adequate ventilation to refresh air between sessions, and follow recommended temperature and time limits for users. Routine upkeep includes cleaning benches, inspecting wood for mold or splintering, checking heater elements or stove components, and verifying seals and insulation. For installation or repairs, seek licensed electricians, HVAC professionals, or licensed contractors through local services in your area; verify credentials and ask for references or prior project photos to confirm experience with residential saunas.

Conclusion

A house sauna can be a durable and enjoyable feature when selected and installed with attention to heat type, materials, ventilation, and safety. Wood-burning and infrared saunas each have distinct installation, maintenance, and user-experience profiles; matching those characteristics to your space, lifestyle, and local regulations will produce the best outcome. Consult qualified professionals for installation and a healthcare provider about any health questions related to sauna use.
