Find filters, water treatment, covers and everyday accessories for your exact cold plunge. Start with the tub model and engine label, then use the matching list below.
Icetubs · Finnmark SoulCold · SaunaLife S1 / FDC-1A · SaunaLife S2 / AP-1 · Kohler
Match the replacement part to the engine as well as the tub. These lists use the verified product and manual compatibility; they do not apply one brand’s water treatment to every plunge.
Icetubs IceBarrel and IceBath

The manual specifies monthly filter replacement for private use and weekly replacement for light professional use. Follow its cleaning schedule and weekly AquaFinesse dose.

Optional insulated cover sized for the S2 tub.
Kohler x Remedy Place
Use the K-35848 manual and exact replacement part number. We can help identify the filter and water-care supplies; cartridges from the other systems on this page are not established substitutes.
A reliable care routine
Shower before entering, keep the cover on between uses, and follow the exact manual’s water-change and cleaning schedule. Give the engine its required ventilation space. Before freezing shutdowns, drain the tub, engine, hoses and filters as directed by the manufacturer. Heating capability does not replace winterization.
These are separately priced products. Buying them together does not create a discount or change their individual warranty. Checkout calculates the full order’s shipping.
