Support

Getting your new sauna up and running

Harvia and Tylö sauna kits are well made and typically straightforward to assemble, with clear, model-specific instructions. If you’re comfortable with flat-pack furniture, you’ll be fine.

Pre-installation: Plan the location, and a solid, level base. For traditional saunas, book a qualified electrician for the heater connection.

  • Home: Check your clearances and ventilation, and have a level base ready. If you’re genuinely stuck, call us for expert advice.
  • Commercial: Same basics as home. Have your electrician verify the building supply early. Some larger heaters may need 3-phase power. Speak to us about your installation if you need advice.
  • Infrared: Cabins with a UK 3-pin plug are plug-and-play into a standard wall socket. Avoid extension leads. Hybrid models with separate sauna heater will need a qualified electrician for the connection.

Calculate the heater kW needed for your sauna

Rule of thumb: Allow around 1kW per 1m³ of effective sauna volume. Extra glass, tile, stone, and log construction can push the requirement higher.

Description

The Harvia Block Large is a flagship 5 person indoor sauna cabin. It boasts a full glass front, clean architectural lines and a rich thermo alder finish. At 2 × 2m, it gives you a more spacious sauna experience than a compact home cabin. There’s more than enough room to sit comfortably, stretch out or enjoy a more social sauna session.

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

Behind the finish, the Harvia Block Large is built with Harvia’s high-performance PIR insulation, 8mm safety glass and a sturdy bench structure designed for daily use. It can be ordered as a sauna cabin only, or as a complete set with a Harvia 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 available on request. Choose alternative timber finishes, glass corner options and RGBW mood lighting for a made-to-order build.
