Cold Plunge Tub & Ice Bath Tub
A cold plunge is a tub used for cold water therapy to reduce muscle soreness, inflammation, and speed up recovery. It’s often combined with a sauna to relieve stress and improve mental health.

Stainless Steel
Stainless steel liner is the most common liner for cold plunges. Of course, from the manufacturer’s perspective, we recommend using stainless steel liner because it has a longer service life. It is no exaggeration to say that a stainless steel liner can last a lifetime, but its price falls into the mid-to-high-end range. Stainless steel liners are usually matched with a wooden or metal exterior.
PVC Liner
Pool Membrane Liner
Alphasauna also offers pool membrane liners—an economical solution commonly used with wooden hot tubs. These liners are typically
installed manually and An affordable alternative to traditional stainless steel or PVC linings However, like all soft liner materials, they have a limited service life and need to be replaced periodically to maintain optimal performance and user experience.
