Indoor Traditional Saunas

Can you have a traditional sauna in your house?

A traditional sauna can go inside a house when it is a model built for indoor use, and every sauna in this collection is one: an electric heater warms a load of stones, and water poured on the stones adds steam. SunRay includes a water cask and spoon for that with cabins such as the Aston, and Dundalk LeisureCraft builds its Element indoor saunas, such as the Nook, for electric sauna heaters only. Indoor models that heat with infrared panels instead of stones are in indoor infrared saunas.

Indoor traditional sauna checklist: room size, power and assembly

• An indoor traditional sauna needs floor space and ceiling height for its cabin: SunRay's nine indoor traditional cabins run from 54 by 36 inches for the Aston 200TN to 71 by 63 inches for the Charleston 400TN and stand 75 to 80 inches tall, while Dundalk LeisureCraft lists its Element saunas at just over 88 inches tall.
• The power supply for an indoor traditional sauna's heater comes from its maker's documents: SunRay lists its indoor traditional cabins for 220 or 240 V, HUUM's US manual lists the DROP 6 kW heater, the Recommended package on the SaunaLife X2 and the Dundalk Loft and Studio, at 25 amps on 240 V, and Finnmark lists the FD-4 Trinity's 1.9 kW Harvia Vega Compact heater at 120 V. Your licensed electrician sizes the breaker and wire from the manual that ships with the heater and your local code.
• Indoor traditional saunas from SunRay, SaunaLife, Dundalk LeisureCraft and Kohler ship as kits, and Dundalk says its Element saunas arrive in ready-to-assemble panels. ThermaSol says its indoor cabins arrive as pre-assembled panels; its installation manuals call for 2 to 4 installers.

Indoor traditional saunas compared

Indoor traditional sauna heaters: included or chosen as a package

An indoor traditional sauna from SunRay, Kohler, Finnmark or ThermaSol comes with its heater, which suits a buyer who would rather not choose one: a 3.5 to 6 kW Harvia electric heater in each SunRay cabin, a FERO heater with stones in each Kohler C1 kit, a Harvia heater beside infrared panels in Finnmark's FD-4 and FD-5, and a 9 kW Harvia Virta in each ThermaSol indoor cabin.

The SaunaLife X2 and Dundalk LeisureCraft's Element saunas are sold with a choice of heater packages, a HUUM DROP marked Recommended on each, so start with them if you want to pick the heater yourself. Heaters bought on their own are in electric sauna heaters.
