Plan your outdoor sauna project
Most buyers who end up disappointed got the sauna right and the project wrong — a pad that was not level, a panel with no spare capacity, a freight truck that could not reach the yard. These three guides cover that ground in sequence.
- 1. Plan the purchase Outdoor Sauna Buying Guide Settle five things before shortlisting a model: heat type, honest capacity, site and foundation, electrical or chimney needs, and all-in first-year cost. Covers permits, shapes and wood species.
- 2. Price the project How Much Does an Outdoor Sauna Cost? Three worked project totals from current prices — kit, heater, electrical, foundation and freight — and why the cheaper sticker is often the dearer sauna.
- 3. Prepare the site Foundation, Drainage and Site Prep Slab, pavers or an existing deck — with deck loads computed from real sauna weights — plus drainage, frost movement, delivery access and the electrical route.
- 4. Size the heater Sauna Heater Size Calculator What kW your room actually needs, matched against manufacturer-published volume ratings rather than a generic formula — plus the corrections for glass and cold climates.
- 5. Check the power Outdoor Sauna Electrical Requirements What circuit your heater needs — 240V amperage by wattage, wire gauge, conduit, permits and installed cost — plus why your heater's own manual overrides any general rule, GFCI included.
Compare before choosing
Three comparisons settle most of what separates one outdoor sauna from another. All three are collected on the comparisons hub.
- Shape Barrel Sauna vs Cabin Sauna The two most common formats on price, usable interior, heat-up time, snow load, foundation and assembly — with median prices computed across every model we track.
- Heat source Infrared vs Traditional Sauna How the two compare on temperature, energy consumption, installation cost, health evidence and session experience — including the 120V-versus-240V difference that decides your install bill.
- Fuel Electric Heater vs Wood-Burning Stove A dedicated 240V circuit against a chimney and its clearances, thermostatic control against independence from the grid, and why the kW ratings are not comparable across fuels.
- Builder SaunaLife vs Dundalk Leisurecraft Thermally modified spruce against solid eastern white cedar, a lifetime warranty against five years, and which one builds the format your site needs.
