Cold water works hard. So do we.

Cold plunges and swim spas hold a small volume of water that gets heavy use, which means water quality matters even more than in a pool. We test and balance the water, clean filters and service chillers, pumps and heaters so every plunge is crisp and sanitary.

We also repair swim spa jets, controls and equipment, and winterize swim spas that shut down for the season. 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.
