Harvia Block Medium 3 Person Glass Front Sauna Kit ThermoAlder Aspen

The Harvia Block Medium is a premium 3 person indoor sauna cabin kit. It boasts a full glass front, clean architectural lines and a rich thermo alder finish. At 1.6 × 2m, it gives you the same flagship Block Large character in a more compact footprint. As a result, it is ideal for refined home wellness spaces where a larger sauna is not practical.

The interior combines warm brushed thermo alder surfaces with pale aspen bench seating. The result gives the cabin a strong contrast between darker wood panelling and lighter touch points. The L-shaped bench layout ensures the space is open and sociable, while the silk-printed glass front allows light into the cabin without losing the private, enclosed feel of a standard sauna room.

Behind the finish, the Harvia Block Medium is built with Harvia’s high-performance PIR insulation, 8mm safety glass and a sturdy bench structure. It can be ordered as a sauna cabin only, or as a complete set with a Virta heater and Fenix WiFi control unit. Left and right-hand sauna heater positions are available, allowing the sauna to suit the layout of your room. Bespoke layouts are available on request with alternative timber finishes, glass corner options and RGBW mood lighting for a made-to-order build.
