To operate correctly, most of the hot tubs and swim spas we offer require a hard-wired electrical hook up with 240 volts and 40 amps, 50 amps, or 60 amps. We do, however, have several tubs that can run on either 120 volts or 240 volts. These tubs are nice when the higher amperage service is not available or when you are not able to alter the electrical service. These are often referred to as “plug and play” hot tubs.
If you are installing your hot tub or swim spa outside in our region, it is recommended that you wire and run it at maximum voltage and amperage. The reason is simple: hot tubs and swim spas operate more efficiently when they are allowed to operate without restriction. In our New England climate, the median annual temperature is around 39 degrees. If you are running your hot tub outside year-round, having a 240-volt connection will save you 40-50% versus a tub that is running on 120 volts under the same conditions.
We also recommend that your required, outdoor disconnect be a GFCI disconnect. This will allow our Service and Maintenance Technicians to work on your hot tub or swim spa without needing to gain access to the main electrical service panel inside your house.
Below are links to each manufacturer’s owner’s manuals. There you can find the electrical specifications for their hot tubs and swim spas by model.

Electrical requirements for saunas can vary greatly depending on the type of sauna, the model and the size.
- Traditional sauna heaters can often be ordered in a few different electrical configurations, such as 240-volt/1-phase, 208-volt/1-phase, or 208-volt/3-phase.
- Infrared saunas often need less power than traditional saunas and can usually run on 120 volts. However, it is highly recommended that you have an electrician run a dedicated line directly to the sauna. Smaller infrared rooms require a 120-volt/15-amp circuit; larger rooms require a 120-volt/20-amp line. [Note: infrared saunas may not operate correctly on a circuit with a GFCI breaker.]
