What this means
- What the maker says it needs. A 120 V plug-in uses a household outlet; 240 V hardwired needs an electrician and its own circuit.
- The manual decides. Circuit size and GFCI protection are the maker's instructions; we do not give wiring advice.
- It is not scored on its own. A plug-in earns one features point; the supply is shown and counted here.
Related questions
- Does a cold plunge need a dedicated circuit? None of the 5 cold plunges we list ask for a dedicated 20 A circuit or a 240 V supply, as their makers state it.
