Will it fit
- Footprint
- 86 x 65 in sourceWidth by depth only. Leil's own page gives this model two heights that disagree, H 2200 mm (86.6 in) and H 90 in, so the height is left blank.
- Placement
- Outdoor
- Plug-in or 240 V
- 240 V: needs a dedicated 240 V circuit, typically installed by an electrician.
- Circuit
- 240V / 30A, as Select Saunas' listing states it.Select Saunas' listing states a 30 amp circuit. Sized from the 6 kW heater by the 125 percent continuous load rule, the minimum is 35 amps on 8 AWG copper. NEC 422 gives the rating marked on a listed appliance authority over that calculation, so both figures can be right; your electrician decides which applies to your run.Check it on the calculator.
Key facts
- Running cost
- About $1.09 per one-hour session: a 6 kW heater at the US average residential rate of 18.16 cents per kWh (EIA, August 2026).
