Buying guide
Compare gentle infrared warmth with the higher temperatures and hot-stone steam of traditional electric saunas to find your preferred sauna experience.
An indoor infrared sauna uses light to create heat and warms your body directly instead of heating the air around you. They aid relaxation by relieving muscle soreness and improving circulation. Home infrared saunas are available in two main types
Far infrared saunas use carbon or ceramic panels to warm your body directly at 45-60°C. Most compact models plug into a 13-amp socket, heat in 10-20 minutes and cost around 20 to 30p per session for a 1.5 kW cabin used for 30 to 45 minutes at 26.32p/kWh. They make a popular choice for everyday relaxation with simpler heating systems.
Full spectrum infrared saunas offer the layered therapy by combining near, mid and far infrared heaters. Most modern full-spectrum cabins feature digital touch-screens to adjust specific wave intensities that match your exact health goals. They cost approximately 26 to 40p per session for a 2-kW cabin used for 30 to 45 minutes at 26.32p/kWh. They are suitable for individuals seeking skin rejuvenation, deep muscle recovery, and intense detoxification
Traditional saunas use an electric heater and hot stones to heat air to 70 to 90°C. Pouring water over stones creates steam for an intense, classic sauna experience. They need dedicated hardwired circuit, fitted by a qualified electrician. Heater size depends on cabin. Roughly 3kW for a compact two-person cabin and up to 9kW for larger ones. They take around 30 to 45 minutes to heat up, and cost about £1.75 to £2 per session. You need good ventilation with protected base. Traditional saunas work best in basements, garages and utility rooms. Electric home saunas come in two main types:
Freestanding cabins made from pre-built panels that fit together to shape the sauna. Quick assembly using pre-made panels that are usually secured with screws or fasteners.
Indoor home sauna kits built inside an existing room using separate wooden panels and pieces. Installation involves building the frame, adding insulation and fitting the wood lining.
Hybrid indoor saunas combine infrared panels with traditional electric stove, giving you the option to prefer gentler warmth or high heat with steam. Hybrid models in the UK start from around £2,549, with options for 2 to 4 people, digital controls, glass fronts and Bluetooth audio. You need to check dimensions and electrical requirements before making the purchase decision.
Explore where your sauna will be placed
Compact cabins fit most spare rooms. Plug-in infrared needs no building work. Allow 1.2m x 1.2m for one person, 1.2-1.6m wide for two, and ceiling ideally 2.1m minimum with 10cm wall gap for airflow. Infrared suits most spare rooms with limited ventilation. Most spare room models seat 1 to 4 people.
Infrared saunas and modular indoor cabins suit basements and garages better with simpler moisture management and power requirements than traditional steam saunas. Basement saunas take longer to heat-up due to colder temperature. Allow a level floor with 2.1m ceiling, 10cm wall clearance and good ventilation. Heaters above 3kW typically need a dedicated RCD-protected circuit installed by a Part P electrician.
Infrared home saunas are best for most bathroom spaces as they fit 1 to 2 people, create low moisture, and require standard set-up. Traditional saunas require large bathrooms and need heavy ventilation with tiled floors and pro-wiring. It is important to keep saunas away from water and always use a certified Part P electrician for safe IP-rated wiring.
You can put your sauna on the roof or terrace. But they require complex installations with careful planning. Before purchasing, request a structural engineer to check the roof’s weight capacity and take planning permission. A leveled base and Part P electrician is needed to safely install weatherproof, RCD protected wiring.
Compact indoor infrared cabins start from around £1,199 to £1,399, and fit a 0.9m x 0.9m footprint. Ideal for spare rooms or smaller spaces. Most run on a standard 13-amp plug with no electrician needed.
Indoor infrared or traditional electric models start from about £2,245 to £2,495. Traditional versions use 6kW heaters and need dedicated circuit fitted by an electrician.
Larger indoor cabins start from £3,640 to £3,875, and are typically 2m wide. Traditional electric heaters are often 6kW and require hardwired installation by a qualified electrician.
Bespoke indoor builds for large families or commercial settings. They need custom sizing with 8kW+ heaters, professional installation and a design consultation.

FAQ
Usually not, if it's treated as an outbuilding under permitted development: typically under 2.5 m tall near a boundary and not in front of the house. Rules vary, so check with your local council.
A level, well-drained base is essential: typically paving slabs, a concrete pad or a ground-screw frame. Allow around 60 cm of clearance on each side for airflow and maintenance.
Neither is better — they suit different habits. Electric heaters are simple and controllable, with most models reaching temperature in around 30–45 minutes. Wood-fired stoves give a softer heat and work off-grid.
A typical session costs around £1–£2 to run, depending on heater size, session length and your energy tariff.
Typically 2–6 weeks for delivery and installation, depending on the model and the options you choose.
Yes. Outdoor saunas are built to live outside all year, so you can use yours in every season.
Think about how many people will use it most weeks, not the occasional party, then check the footprint against your space with clearance on each side.
Keep vents clear, let the cabin dry out after use, and re-treat the exterior timber as recommended for your model.
