Description

The AV-1 Cold Plunge (formerly known as the Aquavoss Model 1) is a dedicated cold plunge system with a deep basin suited for one or two persons. It incorporates an integrated chilling, circulation, and filtration system within a self-contained unit, enabling precise temperature maintenance without external equipment.

Key components include a high-durability acrylic shell, weatherproof aluminum composite panels, insulation via closed-cell foam, and a marine-grade locking cover.

Water clarity is maintained through triple-filtration and ozone, supported by a Panasonic-powered chiller. It requires a standard electrical outlet and offers free curbside delivery in the continental USA, backed by a two-year parts and labor warranty plus five-year structural coverage.
