Questions

The practical stuff.

How many people does the Cube 250 seat?

Five to six, on two thermo-aspen benches. It is the larger cube, built for the garden with a 40mm thermo-spruce frame, a full double-glazed glass front, a half double-glazed panoramic window and a shingle roof.

Electric or wood-fired?

Either. The cube is supplied without a heater so you choose in the configurator above: a Harvia Cilindro 9kW (PC90 manual or PC90XW digital with Wi-Fi), or the wood-fired Harvia Linear 18.

What is the floor and lighting like?

Thermo-aspen duckboard flooring, a sauna ventilation valve and two LED lights on a switch. It sits on three foundation beams.

What comes with it?

The accessories kit: water bucket, ladle, hygrometer and thermometer, and a sauna timer.

Is it safety certified?

Yes. The sauna is independently tested and certified to the electrical-safety standards of both Europe and North America.

Do you deliver and set it up?

Yes. Our own team delivers, positions and commissions every unit, anywhere in Ireland, so you never need to arrange installers separately. Installation is not included in the price shown; we quote and agree it with you after purchase.

Wood-burning

Harvia Linear 18

The Harvia Linear 18 is a wood-burning stove for an authentic, off-grid sauna ritual. The crackle of the fire and the deep, enveloping heat of a real burn create an experience no electric heater can match — ideal for outdoor cabins beyond a power supply.

Output options

14.3 kW (Recommended)

Electric vs wood-fired

This cabin can be heated two ways. Pick the ritual that suits you:

  • Electric (Harvia Cilindro). One-touch convenience with precise temperature control and optional Wi-Fi scheduling. Ready to bathe in 30 to 45 minutes, with no fuel or flue to manage.
  • Wood-fired (Harvia Linear 18). The traditional experience, with the crackle and aroma of a real fire and a deep, enveloping heat. Needs no power supply, so it’s ideal for off-grid gardens.

Both reach full löyly temperature. The choice comes down to convenience versus authenticity.

Electric

Harvia The Wall

Harvia The Wall is a slim, wall-mounted electric heater designed to free up bench space in compact cabins. Despite its low profile it carries a deep stone bed for a full, steamy löyly, and its minimalist black face sits flush against the cabin wall.

Available in 6 kW and 9 kW outputs to match smaller and larger rooms.

Output options

6 kW Digital controls

  • Mini Cube, Mini Cabin and Traditional 160

9 kW Digital controls

  • Cabin, Traditional 160, 210, 210x and 220

About your heater

The Harvia The Wall is a wall-mounted electric heater designed to sit quietly in the cabin. A slim glass-and-steel front hides a generous bed of sauna stones behind it.

  • Fast to temperature. Reaches full bathing heat in around 30 to 45 minutes.
  • Effortless control. Set and hold your temperature precisely, with optional Wi-Fi scheduling from the control panel.
  • Soft, even löyly. A large stone capacity gives a gentle, enveloping steam when you ladle water over the rocks.

A floor-standing heater can also be supplied with this sauna. Ask us about the options available.

Electric

Full-spectrum infrared

Output options

1.5 kW App control by Wi-Fi (Included)

  • Infrared 100

2.4 kW App control by Wi-Fi (Included)

  • Infrared 130 and Infrared 160

How infrared works

Full-spectrum infrared warms your body directly with radiant heat. It does not heat the air like a traditional sauna. The result is a gentler, more breathable experience at a lower air temperature.

  • Ready in minutes. No long pre-heat. The emitters warm you from the moment you step in.
  • Lower temperature, deep warmth. Comfortable at around 45 to 60°C. It suits longer, relaxed sessions.
  • Simple to run. Works from a standard supply. No stones, water or steam to manage.

A great choice if you find traditional sauna heat too intense.

Electric

Harvia Cilindro

The Harvia Cilindro is a sculptural, free-standing electric heater with a cylindrical stainless-steel basket that holds a generous bed of stones for soft, even löyly. Its wraparound stone surface radiates heat from every side, warming the cabin quickly and holding a stable temperature throughout your session.

Controlled by a wall panel or the optional Wi-Fi app, it suits regular home use and pairs beautifully with the glass-fronted Cube and Barrel cabins.

Output options

9 kW PC90 manual controls

  • Reaches 60 to 70°C (mild heat)

9 kW PC90XW digital + Wi-Fi (Recommended)

  • Heats up to 110°C
  • Includes Harvia Fenix Wi-Fi control panel
