Cold water works hard. So do we.

Bought a cold plunge and need it set up right? We install cold plunges at home, from siting the tub and the GFCI protected electrical to the water line, the chiller hookup and a full startup. Whether it is a portable plunge, an in ground cold plunge or a built in setup, we get the temperature holding and the water balanced before we leave.

We also repair cold plunge chillers, pumps and controls when a plunge stops holding temperature, service swim spa jets and heaters, and winterize swim spas that shut down for the season. Cold plunges and swim spas hold a small volume of water that gets heavy use, so we test and balance the water and clean filters to keep every plunge crisp and sanitary. Serving the Seattle wellness community from Ballard to Bellevue and everywhere in between.

Questions, answered

Cold plunge and swim spa FAQs.

How often should a cold plunge be cleaned?

Because the water volume is small and use is frequent, most cold plunges need weekly water care and a full drain and clean every few weeks depending on use. We set a schedule that keeps the water crisp and sanitary.

Do cold plunges need chemicals?

Yes. Cold water slows bacteria but does not stop it. A plunge still needs sanitizer and balanced water, just in smaller, carefully measured doses. We handle the chemistry so it is safe every day.

Is a swim spa harder to maintain than a hot tub?

A swim spa holds more water and works harder, but the routine is similar: testing, balancing, filter care and equipment checks. We service both on the same plan.

Should a swim spa be winterized in Seattle?

If you use it year round, no, it can run all winter. If you shut it down for the season it must be properly drained and blown out to prevent freeze damage. We handle both.

What is a swim spa?

A swim spa is a compact pool with a powerful current you swim against, part lap pool and part hot tub. It fits on a patio or backyard pad, runs year round in our climate and doubles as a warm soak. We maintain, repair and winterize swim spas of every major brand.

How cold should a cold plunge be?

Most people plunge between 45 and 55 degrees, with experienced users going colder. Holding that temperature reliably depends on a healthy chiller and clean, balanced water, which is exactly what our cold plunge maintenance keeps in shape.

Can you install a cold plunge?

Yes. We set up cold plunges at home, including siting the tub, the GFCI protected electrical, the water line and the chiller hookup, then start it up and balance the water so it is ready to use. We install portable, in ground and built in cold plunges across the Seattle area.

Do you repair cold plunge chillers?

Yes. A cold plunge that will not hold temperature usually points to the chiller, the pump or low flow from a dirty filter. We diagnose and repair cold plunge chillers, pumps and controls, and replace the water chiller for a cold plunge when it is past saving.

Recovery ready

Keep the plunge cold and the current strong.
