Description

Fortis

Fortis, meaning strength in Latin, is a sleek, enclosed outdoor sauna designed for 3–4 people. Its modern eave-style roofline and glass front offer a private yet light-filled retreat built for year-round use.

Inside, thermally modified brushed wood walls and aspen benches create a warm, inviting space. LED color light therapy adds ambiance, while multi-layer insulation and a protective roof ensure energy-efficient performance in any season.

A powerful 9kW Harvia heater comes standard, with digital controls and optional WiFi integration for added convenience.
