Sizing & Installation Guide

How to Choose the Right 8-Person Sauna

Critical space, electrical, and weatherproofing factors to verify before ordering:

01

Bench Width & Ergonomics

For 8 adults to sit comfortably side-by-side, verify an interior bench width of at least 100″+.

02

Power Supply: 120V vs. 240V

120V plug-and-play works well for indoor infrared. Traditional rock stoves in outdoor climates require dedicated 240V (30A–40A) hardwiring.

03

Material Selection & Durability

Prioritize Western Red Cedar or ThermoWood for outdoor weather resistance. Indoor infrared performs best with hypoallergenic Canadian Hemlock.

04

Insulation & Climate Rating

For unheated garages or freezing winter locations, look for insulated double-wall panels or minimum 1-3/8″ thick solid staves.

Frequently Asked Questions

How much space do I need for a 8-person sauna?

A quality 8-person sauna requires an average footprint of 75 to 110 sq ft with an internal bench width of at least 100″+. This ensures occupants can sit side-by-side without touching shoulders, or allows one adult to lie down.

Do 8-person saunas need 120V or 240V power?

Commercial 240V (50A–60A) or commercial wood-fired stove. Infrared saunas up to 2-3 persons frequently run on 120V (15A or 20A). However, traditional stone-heated outdoor barrels and cabins always require a dedicated 240V line (30A–50A) to support 6kW–9kW heaters.

What is the difference between indoor and outdoor 8-person saunas?

Indoor saunas (typically infrared) feature untreated hemlock/basswood cabinetry, low-EMF emitters, and 120V plugs designed for climate-controlled rooms. Outdoor saunas (barrels and cabins) feature weather-resistant Western Red Cedar or ThermoWood staves, asphalt shingle roofing, and high-kW stone heaters engineered for freezing outdoor climates.

What is the best wood type for a 8-person sauna?

For outdoor barrel or cabin installations, Canadian Western Red Cedar and ThermoWood offer the highest resistance to rot, fungal decay, and weather warping. For indoor infrared units, Canadian Hemlock provides clean hypoallergenic performance with zero resin bleeding.
