Company

BlueCube Wellness LLC of Redmond, Oregon, founded in 2019, builds cold plunge tubs from a 33-inch upright aluminum tub to a 72-inch stainless sit-in tub.

Where it sells

It sells them in the US through its own store at bluecubebaths.com and ships each tub curbside in the lower 48 states.
No BlueCube store or listing was found on Amazon US in November 2026.

Description

The BlueCube C1 is a lay-down cold plunge with a 14-gauge 316-L stainless tub, 60 by 24 by 22 inches inside, set in a Line-X coated plywood cabinet with spray-foam insulation. Its footprint is 92.5 by 37.5 by 28.5 inches, and the brand FAQ puts the C-line tubs at 80 to 100 gallons.

The current page rates it from 41°F to 104°F with a heater and a 13,600 BTU/hr (1.5 HP+) chiller that runs down to 20°F ambient; an older brand page lists 37°F to 70°F and a 1 HP chiller. One ¼ HP Iwaki pump circulates the water through a 20 micron filter with automatic ozone, and an app and lights come standard.

It needs a dedicated 120 V 20 A circuit or can be hardwired, and ships with a GFCI cord, an insulated cover with child locks and a maintenance kit.

Colours and an uncladded finish cost the same; a custom colour adds $2,500.00, a hardwood deck $4,000.00, a tub material upgrade $3,000.00, reverse plumbing $2,000.00 and powder-coated screens $1,000.00.
