TUNDRA's sauna range covers three distinct heat technologies — infrared, steam, and traditional Finnish — each suited to different spaces, rituals, and recovery goals. All delivered and set up in Singapore.
Traditional Finnish sauna — Haven (from S$21,490): Canadian red cedar, Harvia 6 kW electric heater, 8 mm tempered glass front. Reaches 80–100°C with the option to add steam via löyly. The most extensively researched sauna type, with the strongest long-term cardiovascular and longevity evidence. Outdoor installation, delivered and commissioned. Pair with a cold plunge for full contrast therapy.
Full-spectrum infrared — Equinox (from S$5,590) & Equinox SOL (from S$5,890): Infrared panels heat the body directly at lower ambient temperatures (40–60°C) — fast to heat (10–15 minutes), compact enough for most indoor rooms, with colour light therapy and low-EMF panels. The Equinox is the indoor model; the Equinox SOL is the outdoor-rated version in a weatherproof build.
Portable steam — Vapora (from S$490) & Caldera (from S$1,388): Enveloping humid heat, spa-grade experience, no plumbing or permanent installation. The Vapora is a single-person unit that folds flat for storage — the simplest entry point into heat therapy. The Caldera is a reinforced drop-stitch fabric steam sauna available in 1-person and 4-person formats, built for more intensive use and group settings.
