Home Sauna Advice & Installation Support

Home saunas are a meaningful wellness investment and the right setup depends on how it will be used. EvoHome Improvements helps homeowners across Hampshire and the South think through traditional (stove-heated) vs infrared saunas, indoor vs garden cabin, size and seating, timber choice, controls, electrical supply, ventilation, fire/insurance considerations and how a sauna pairs with a shower, ice bath or garden room.

Outdoor cabins also need a base, levels and weatherproofing thought through. EvoHome Improvements advises and coordinates — independent vetted specialists carry out the physical installation, electrical work and certification. We do not quote fixed prices, exact timescales or guaranteed health/wellness outcomes without a proper site assessment, and always recommend appropriate medical advice for sauna use.

Home saunas have moved from luxury to mainstream as health benefits become increasingly well-documented. Regular sauna use is associated with improved cardiovascular health, reduced stress, better sleep, and enhanced recovery from exercise.\n\n## Traditional vs Infrared\n\nTraditional Finnish saunas heat the air to 70–100°C using electric or wood-fired heaters, with optional steam (löyly) from water thrown on hot stones.

Infrared saunas use panels that heat the body directly at lower air temperatures (45–65°C), making them more energy-efficient and faster to heat. Both offer genuine health benefits, but the experience differs significantly.\n\n## Indoor vs Outdoor\n\nIndoor saunas integrate into spare rooms, garages, or purpose-built spaces.

Outdoor saunas — particularly barrel designs — have become popular garden features. Outdoor units benefit from the contrast of cold air or cold water plunge post-sauna, enhancing the health benefits.\n\n## Electrical Requirements\n\nSauna heaters typically range from 3kW (small 2-person) to 9kW+ (large family sauna). Units over 3.

5kW require hardwired installation by a qualified electrician. A dedicated circuit with appropriate MCB protection is essential.\n\n## Ventilation Design\n\nProper ventilation is critical for safety and performance. Fresh air should enter near the heater (low level) and exit at the opposite end (high level). This creates natural convection that distributes heat evenly while maintaining air quality.
