01 · The Setting

Built for the pool. Part of the landscape.

Designed to complement an existing backyard pool, this custom outdoor sauna and cold plunge were carefully integrated into the landscape, creating a seamless extension of the outdoor living space.

02 · The Sauna

Glass, cedar, and open sky.

The sauna features a striking contemporary design with angled architectural framing, expansive insulated glass walls, and a glass roof offering panoramic views of the surrounding greenery. Both the interior and exterior are finished in natural knotted cedar, with custom tiered benches, Himalayan salt accents, and a HUUM stone heater. A decorative metal tree installation adds a unique artistic touch to the warm wood interior.

03 · The Cold

Cold, steps from the pool.

The accompanying cold plunge features a fully insulated stainless steel vessel with wood cladding and an external chiller for precise temperature control. Designed to perfectly match the existing poolside setting, the sauna and cold plunge create a cohesive outdoor wellness retreat that combines modern architecture, natural materials, and year-round relaxation.
