The Tiburon 4-Person Indoor Traditional Sauna is designed for households that want real room to relax without dedicating an entire room to a sauna. Built from aged Canadian hemlock with two-tier seating and ergonomic backrests, it’s comfortable for solo resets, couples, or family sessions. A powerful Harvia® 6.0 kW heater delivers fast, even heat and classic Finnish-style steam (löyly) when you add small water pours to the stones.
