Choosing the right sauna size

Sauna capacity is generally stated as a maximum seating guide, not a maximum comfort guide. Use the points below to specify what will work best for your needs.

Practical sizing rules

Factor Allowance
Seated adult bench space Around 600mm width per person
More comfortable seating 700mm+ width per person
Bucket and ladle space Allow 200–300mm width
Lying down Around 1800–2000mm bench length
Heater, door and access space Don’t count this as usable seating space
L-shaped or opposing benches Better for families, guests and more social use
Commercial use Size for comfort, flow and turnover, not just headcount

Typical sizing scenarios

Use case What to allow for
Single regular user A compact sauna can work well, but choose enough bench length if you want to stretch out.
Couple A 2 person sauna may be enough, but a 3 person layout usually feels more comfortable.
Family use Prioritise movement, access and a layout that lets people sit without crowding the door or heater.
Occasional guests Size around normal use first. A 4 person sauna may feel better for 2–3 regular users.
Social use Consider L-shaped or opposing benches so users can face each other rather than sit in a single row.
Relaxed home sauna Allow more width per person, space for towels, accessories and easier movement.
Commercial sauna Consider peak demand, session turnover, safe movement, cleaning access and customer comfort.

Not sure what size is right for you? Send us your room dimensions and intended use, and we’ll help you narrow it down.

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 Harvia Alaska Corner Infra+ is a 4–5 person hybrid home sauna cabin designed for daily sessions. The corner footprint saves space, while the full-height safety-glass door and panels keep the room bright and open. Step inside and you’ll feel the difference a Harvia sauna delivers. Solid spruce construction, refined ‘Prestige’ lime-wood interior and spacious seating all combine to make this a premium experience,

Use classic sauna heat when you want that traditional hot-room ritual, or switch to full-spectrum infrared for a more direct, lower-air-temperature warmth many people find easier to stay with. There’s also the option to combine the two, so heat can build steadily without turning the session into a sprint. Simple controls make it easy to settle in and relax.

Comfort comes from the details. Enjoy supportive backrests, adjustable head support, sensible ventilation, and a floor grid that feels secure underfoot. Add the optional RGBW LED lighting set and the cabin takes on a soft, calming glow that makes evenings match your mood. If you want a spacious home sauna that feels bigger than its footprint, the Harvia Alaska Corner Infra+ won’t disappoint.

Features

  • Corner-first cabin: Design that makes smart use of floor space without compromise.
  • 4–5 person layout: Seating and lounging that feels genuinely usable, not just marketing.
  • Two-level benching: Sit upright for conversation, or stretch out and let the heat do its thing.
  • Harvia Prestige: Lime-wood interior for a smooth feel against warm skin and a premium look.
  • Solid spruce build: Sturdy, reassuring cabin and helps heat feel steady once you’re in.
  • Open glass frontage: Door and panel that keeps the experience open and modern not boxed-in.
  • Hybrid Infra+ experience: Choose classic sauna heat, full-spectrum infrared warmth, or both.
  • Seating and support: Backrests and adjustable  headrests support longer, more relaxed sessions.
  • Heater protection guard: Practical safety buffer for peace of mind without spoiling the look.

  • Solid spruce cabin (40mm walls), solid roof elements and rim.
  • Full-height safety glass door (reversible hinge: left/right).
