Renu Therapy

Renu Therapy is a Southern California company, founded in 2020 and based in Costa Mesa, that designs and builds cold plunge tubs by hand in California.

In this category it sells five cold plunges with built-in chillers, from a compact upright tub to a large wood-body tub, some of which also heat, plus two lines of traditional cedar saunas with electric stoves: indoor cabins and outdoor barrels.

It sells through its own US store at renutherapy.com, with free curbside delivery to the contiguous US; the plunges ship assembled and the saunas ship unassembled.
