Steam & Oak Koda 220 Compact Garden Sauna, 2.0 x 2.2m (Spruce or Thermowood)

The Koda 220 is a compact garden sauna with a rounded roof and a 2.0 m² hot room. It comes in natural Nordic spruce or thermowood, with a solid timber front or a full glass front, so a small sauna can still feel open.

Choose your heater at checkout

• Shell only. The complete sauna, you source your own heater.
• Harvia Cilindro PC90 9kW. The classic Cilindro pillar with its tall stone column, 90kg of stones, controls built into the heater. Harvia rate it for rooms of 8 to 14m³.
• Harvia Cilindro PC90XW 9kW WiFi. The same heater with MyHarvia app control, so you can start it from the house. Supplied with the Harvia door sensor, which the electrical sauna standard requires before any heater can be started remotely. Most sellers leave that part off the quote.
• Harvia M3 wood fired. The classic Finnish log burning stove, rated by Harvia for rooms of 6 to 13m³. No electrics at all, no standing charge, and the ritual of building the fire. Supplied with a stainless steel chimney, and we confirm the chimney route with you before you order.

Sizing the heater. Harvia size heaters on the room volume, then add 50% for solid log walls and about 1.2m³ for every square metre of glass, because both soak up heat that an insulated panel would not. The Koda 220 glass front adds a lot of glass, so both versions take the 9kW Cilindro or the Harvia M3 wood stove. The hot room is also within the FinSteam gas rating.

We would rather sell you the right heater than the cheapest one. Tell us where the sauna is going and how you plan to use it, and we will confirm the choice with you before you order.

Also available with gas

Pick a gas option at checkout and we fit the sauna for gas: ventilation built for gas, plus a FinSteam gas heater package that runs on a standard UK propane bottle. No electrician, no chimney and no fire to tend. It heats in around 15 minutes from a dial.

• Botnia 81. Our standard 8.1kW gas heater. Everything you need to run the sauna.
• Aurora 81. The premium version of the same 8.1kW heater, with a better finish and detailing, oxygen depletion auto shut off and flame monitoring.
• With the safety pack. Adds the Njord heat shield and the Halo guard rail. The heat shield lets the heater sit closer to the timber wall, and the rail stops anyone brushing the hot stones. If you have children, guests, or you rent the sauna out, choose this one.
• Without the safety pack. Heater and stone cage only. Talk to us first, because under the rounded roof the timber curves in above the heater and we will usually recommend the heat shield.

FinSteam rate the 8.1kW heaters for barrels and other uninsulated rooms of up to about 8m³ of air, which is why gas is offered only where the hot room fits that range.

Every gas option includes the heater, the Orbis stone cage, 40kg of pre washed sauna stones, a UK propane regulator and CE marked gas hose, and our fitting and commissioning. Our installer fits wooden louvre vents at the sizes FinSteam specify: a low intake beside the heater drawing air from outside, and a high exhaust in the opposite corner. You source a standard 13kg propane bottle locally, and a fixed gas connection needs a Gas Safe registered engineer. See the full gas heater range.

Before you order: your electricity supply

The electric heaters are not plug in appliances. For the 9kW Harvia specify a 3 x 16A supply on three phase, or a single 50A supply on 10mm² cable if your property is single phase, which most UK homes are. Over a buried run to a garden building that cable size usually needs to go up again for voltage drop. Budget for a qualified electrician and a Part P sign off. The wood stove and the FinSteam gas variants need no electrical supply.

Tell us your supply type and main fuse rating when you enquire and we will tell you honestly what will and will not work before you commit.
