SaunaBox Forge 1-Person: Traditional Finnish Sauna

Our most powerful sauna yet. The Forge delivers the raw, elemental power of traditional high-heat sauna -- refined into a modern architectural statement built for your backyard.

Designed for those who crave real heat, Forge reaches up to 220°F (104°C) with its powerful 3.5kW Harvia® heater, creating a deep, enveloping warmth that transforms every session into a full-body reset.

Every detail has been considered. From the rich grain and natural aroma of 100% Canadian Hemlock to the black-tinted tempered glass that adds privacy with a sleek edge, Forge balances performance with presence. Integrated ambient lighting softens the space, turning powerful heat into a calming ritual.

Built specifically for indoor or outdoor living, Forge is weather-resistant and engineered to endure the elements year-round. Rain, sun, cold evenings -- your recovery routine doesn't stop. Serious heat, built to last.
