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.
- 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.
The BlueCube Deep is an upright stand-in cold plunge with a contoured 33 by 33 by 43 inch welded 5052 aluminum tank deep enough to dip the head. Two ¼ HP Iwaki magnetic-drive pumps drive the current, and the chiller, pumps and filter sit in a separate entry staircase with a Balboa topside panel.
The brand rates it from 41°F to 104°F with a heater as well as a chiller, and its FAQ gives the D-line tubs 180 gallons. No chiller capacity is published for the Deep on the current pages; an older catalog page for the earlier D2 printed 13,600 BTU/hr.
It filters to 20 micron with automatic ozone, needs a dedicated 120 V 20 A circuit, and ships with a GFCI plug, an insulated spa cover, three months of filters and six months of cleaning supplies. Five colours cost the same; a custom colour costs $17,250.00 in total.
A remote component box install is quoted per project.
