Cold Tubs & Cold Plunge FAQ

Portable or hard-shell — which should I choose?

Portable tubs are the lowest-cost way to start and store easily. Hard-shell tubs are more stable, more comfortable, and better for frequent long-term use.

Do I need a chiller?

If you want consistent temperatures year-round, a chiller-ready setup is the best solution. Without a chiller, water temperature will depend on ambient conditions.

How do I keep the water clean?

Clean water is about routine: filtration (where available), sanitation method, and keeping the tub covered. Showering before use helps dramatically.

Indoor or outdoor cold plunge?

Indoor is easier to keep clean and use year-round. Outdoor is great for space and atmosphere but needs covering and sensible drainage planning.
