Cold Plunge Tubs & Chillers

Yukon Cold Plunge Tub

This will depend on whether you are using the tub with a chiller or as a standalone and whether or not you are treating the water with sanitizer.

If the tub is used without a chiller (i.e. ice cooling) and without a sanitizer like bromine, then we recommend changing the water after each session.

If you are not using a chiller, but you are using bromine and oxidizer, then your water may last 7 days or so. Although this varies depending on how often you use the tub.

If the tub is used with a chiller, the chiller’s pump and filter will circulate and clean the water, so you can change the water less frequently. If you are using a chiller and bromine/oxidizer we recommend changing the water every 2 weeks depending on how frequently you use the tub. The more frequently you use the tub, the more often you should change the water.

The tub is made of double walled PVC. PVC is both durable and easily repairable in case of a tear during use. A PVC patch kit is included with every tub just in case.

Yes! A PVC cover is included with the tub. The cover pulls tight around the edges of the tub and keeps out any leaves or debris.

The plunge tub’s dry weight is 30 lbs. Filling with water will add an additional ~1,000 lbs. Your foundation must be strong enough to support the full weight of the tub (.1,000 lbs).

We recommend placing the tub on a concrete pad or wooden deck that is engineered to support the weight of the filled tub.

We do not recommend placing the tub directly on dirt as it can sink into the ground due to the weight.

The tub walls have a ~3" air buffer, which insulates the water. This is an effective method and is the same principle as how a thermos is insulated.

How fast the tub loses or gains heat largely depends on the external temperature. If there is a big temperature difference between your tub and the outdoor air, it will heat up faster.

The bromine kit and water balancing kit serve different purposes, and both are required to keep your water clean if you plan on changing your water infrequently.

The bromine kit is used to keep the water sanitary. This is required to keep your water free of bacteria that can cause itchiness, pink eye, and other conditions associated with pool use.

The water balancing kit is used to keep your water with an acceptable pH, alkaline, and hardness level. If your water’s levels get out of balance, it will damage your chiller equipment.

Any damage to the chiller or plunge tub due to improper water maintenance is not covered under Redwood Outdoor’s product warranty or 3rd party equipment warranties.

When testing your water, the water should be tested at room temperature. The best way to test cold plunge water is to take a small sample in a cup. Allow the cup to sit indoors for a couple of hours and then test it as normal.

If you change your water frequently (e.g. after each use), your water will be naturally clean and the use of chemicals is likely not required.

The hoses screw onto the inlet/outlet connections on the long side of the tub.

The y-shaped hose should connect to the chiller's inlet and then to the two bottom connection points on the tub.

The straight hose should connect to the chiller's outlet and then to the top connection point on the tub.

An example of how the tub is connected is below.
