Infrared sauna electrician guide

When 120V kits may plug in vs when 240V or custom needs a dedicated circuit. All amps UNVERIFIED until your label agrees.

Short answer

Situation	Likely path	Do this
FD-1 / FD-2 on 120V-class listings	Often standard receptacle language	Read Topture page; prefer a dedicated circuit if the listing asks
FD-3	Often 240V on listings	FD-3 240V page before checkout
SaunaCloud Atlas / many customs	Dedicated 240V class common	Quote plans → licensed electrician
SaunaCloud compact / Atlas One	Per quote PDF	Do not assume any wall outlet
Sweaty Yeti outdoor	Often 240V / 50–60A class	Electrician + pad before deposit

Buy heat after the circuit plan exists — not before.

120V kits — plug in is not share with a space heater

Screenshot voltage, amps, and plug from Topture.
Ask whether the circuit must be dedicated.
Do not daisy-chain with compressors, shop tools, or space heaters.
If the panel is far or the garage/basement run is long, get a written estimate anyway.

FD-1/FD-2 size pick: Finnmark FD compare.

240V — FD-3 and most custom builds

FD-3: treat 240V as the default planning assumption until the live listing says otherwise (UNVERIFIED pattern) — full gate: FD-3 240V.

SaunaCloud: electrician works from their drawings. Atlas often needs 240V/30A-class service. Quote first: SaunaCloud. Models: Atlas vs Sierra.

Cost honesty: outlet/circuit work often lands from low hundreds to low thousands by distance and panel (UNVERIFIED local). Compare that to upsizing the cabin.

Who should skip

Skip checkout today if voltage is unclear or no electrician estimate exists for a 240V job.
Skip medically if heat stress is off-limits.
Skip mixing Plunge Chill compressors onto the same overloaded circuit as the sauna.

Bottom line

120V-class FD-1/FD-2 may plug in per listing — still respect dedicated-circuit language. FD-3 and most customs need a real 240V plan first. All amps UNVERIFIED. Kit vs custom: Finnmark vs SaunaCloud.
