Why BlueCube

Why a BlueCube cold plunge tub

Handbuilt, one at a time

Every tub is welded, finished and tested in Redmond, Oregon — 316L stainless on the C-series, double-wall 5052 aluminum on the D-series. No rotomolded plastic, no inflatables.

What a BlueCube costs, model by model

RiverMode™ hydro-agitation

Still water lets a warm layer form on your skin. RiverMode™ keeps the water moving across your body, so the same tub keeps challenging you for years.

Water that stays ready

20-micron filtration and automatic ozone sanitation with 24/7 temperature hold. No ice runs, no draining every few days.

FAQ

Residential to commercial

The Drop through the Limitless covers a home garage to a gym floor. C2X / C3X commercial packages add tub-material upgrades and chlorine-drip or AOP sanitation.
