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.

Description

The cleverly design Harvia Polaris Large is a 5 person angled-entry sauna cabin in spruce, with both domestic and commercial sauna applications. The diagonal doorway entry isn’t just a space-saving design flourish, it also allows people to step in and out without squeezing past benches or bumping shoulders.

Inside, the Harvia ‘Prestige’ lime-wood interior is all about comfort and durability. 3 wide benches across 2 levels give you plenty of room to sit upright or slide back when you total relaxation. Add in supportive backrests and headrests, and the cabin starts to feel like a place you’ll use and admire. The full-height safety-glass door keeps the space bright and open, even when the heat is doing its job.

For commercial environments, the solid spruce build and practical safety details (heater guard, floor grid, protected lamp, and ventilation slit) make day-to-day running feel straightforward. The the cabin can be mirrored with left or right door hinging to suit your space.

Features

  • Angled-entry design: Sauna tucks neatly into corners while keeping the doorway open and easy to approach.
  • Five-person capacity: Ideal for sociable sessions, family routines, or small-group commercial wellness use.
  • Tiered bench layout: Gives everyone their preferred heat level, lower for gentle warmth, upper for full intensity.
  • Relaxing sauna benches: Designed for care-free relaxation, with seating and lounging space that feels generous.
  • Lime-wood ‘Prestige’ interior: Looks premium, feels smooth to the touch, and keeps the atmosphere light.
  • Solid spruce exterior: Delivers the traditional Nordic cabin look with a reassuring, durable and sturdy feel.
  • Full-height glass door: Keeps the cabin bright, reduces that closed-in feeling, and adds a modern finish.
  • Left or right door hinging: Ensures the cabin fits the room layout instead of forcing the room to fit the cabin.
  • Supportive backrests: Designed for longer, more comfortable sessions, especially in commercial settings.
  • Heater burn guard: Helps protect users from accidental contact making it ideal for shared or guest settings.
  • Practical ventilation hatch: Designed to help the cabin air feel fresh and balanced throughout the session.
