Home Sauna Buying Guide: Infrared vs Traditional, Sizing and Electrical

Home saunas have moved from luxury to mainstream wellness equipment, and prices now span from under $3,000 to well past $15,000. The right choice depends on one core decision, infrared versus traditional, and a handful of practical constraints. Here is the honest breakdown.

Infrared vs traditional: the real difference

Traditional (Finnish) saunas heat the air to 150 to 195 F with an electric or wood fired heater, and you ladle water over stones for steam. The experience is intense heat, deep sweating and loyly humidity bursts.

Infrared saunas use emitter panels that warm your body directly at a much lower air temperature of 115 to 135 F. Sessions are gentler, easier to tolerate for 30 to 45 minutes, and the cabin plugs into ordinary household power in many cases. Full spectrum models such as the Enlighten InfraNature series combine near, mid and far infrared wavelengths.

Choose traditional if you grew up with steam saunas or want the classic high heat ritual. Choose infrared if you want longer, milder sessions, faster warm up, and simpler electrical work.

Indoor or outdoor

Indoor cabins install in a basement, gym or large bathroom, need a nearby circuit and a level floor, and stay out of the weather. Outdoor saunas, including barrel saunas, become a backyard feature but need a foundation (pavers or a concrete pad), weather rated construction, and a plan for running power. Cedar and thermally treated woods handle the elements best.

Electrical: check before you buy

• Small infrared cabins (1 to 2 person): often plug into a standard 120V 15 or 20 amp outlet.
• Larger infrared and most traditional heaters: require a dedicated 240V circuit, commonly 30 to 60 amps, installed by an electrician.
• Wood fired stoves: no electrical, but check local codes for clearances and chimney requirements.

Sizing

A 2 person sauna is genuinely comfortable for one person lying down or two sitting. If two of you will use it together regularly, buy a 3 to 4 person cabin. Ceiling height matters in traditional saunas: heat stratifies, so benches at two levels let you choose your temperature.

What should you spend?

Quality 2 person infrared cabins start around $3,000 to $5,000. Premium full spectrum and low EMF models run $5,000 to $9,000. Traditional indoor rooms with heater typically land $4,000 to $10,000, and outdoor barrel setups $5,000 to $12,000 depending on wood and stove. Delivery is curbside freight; plan two people for assembly, which is typically a half day of panel bolting.

FAQ

How much does a sauna cost to run?

An infrared session draws roughly 1.5 to 3 kWh, about 25 to 50 cents at average US rates. Traditional heaters draw more, 6 to 9 kW while running, but sessions are shorter.

Is low EMF marketing or real?

Emitter EMF varies by build quality. Reputable brands publish tested milligauss numbers at bench distance. If EMF matters to you, buy from a brand that publishes figures rather than adjectives.

How long from order to first sweat?

Freight delivery typically runs 1 to 3 weeks, assembly a weekend afternoon, plus an electrician visit if you need a 240V circuit.
