KOVE Outdoor Barrel Sauna | 3–4 Person Garden Sauna with 6kW Harvia Electric Heater

Premium Outdoor Sauna with Genuine Harvia Heater

Create your own outdoor wellness space with the KOVE Barrel Sauna – 3–4 Person, a premium traditional outdoor sauna designed for authentic heat, comfortable shared sessions and year-round use in the UK.

Crafted from premium Canadian Spruce and supplied with a genuine Harvia 6kW electric sauna heater as standard, the KOVE Barrel combines timeless sauna design with a spacious interior and integrated front porch seating. Its rounded profile supports natural heat circulation, while the weather-protected shingle roof makes it a considered addition to gardens, patios and dedicated outdoor wellness spaces.

Traditional Barrel Design for Efficient Heating

The distinctive rounded barrel profile is more than an iconic sauna design. With less unused air space than a conventional square cabin, heat can build efficiently and circulate naturally throughout the interior.

This creates a comfortable sauna environment while making effective use of the 6kW heater.

• Comfortably accommodates three or four adults
• Rounded profile supports natural heat circulation
• Compact footprint for gardens, patios and outdoor wellness spaces
• Efficient internal volume
• Classic outdoor sauna appearance

Integrated Front Porch Seating

Designed with relaxation in mind, the KOVE Barrel features an integrated front porch with twin bench seating.

Enjoy a place to cool down between sessions, prepare before entering the sauna or simply take in your surroundings after a warm session outdoors.

• Integrated front porch
• Twin exterior bench seats
• Convenient cooling and resting area
• Distinctive traditional barrel design

Crafted from Premium Canadian Spruce

The KOVE Barrel Sauna is built from carefully selected Canadian Spruce, a timber widely used in traditional sauna construction for its strength, stability, natural insulating properties and attractive pale finish.

The spruce creates the bright, calming interior associated with Nordic-style saunas while providing the structural performance required for outdoor use throughout the changing British seasons.

• Solid Canadian Spruce construction
• 38mm timber thickness
• Natural insulation and heat retention
• Strong structural stability
• Smooth internal bench seating

Timber is a natural material. Variations in grain, knots and colour are normal and form part of the unique character of every sauna.

Powered by a Genuine Harvia Heater

The KOVE Barrel Sauna – 3–4 Person comes with a genuine Harvia 6kW electric sauna heater as standard.

Designed by Harvia, one of Finland's most respected sauna brands, the heater is matched to the internal volume of the cabin to provide dependable performance, even heat distribution and a traditional stone-heated sauna experience.

• Genuine Harvia 6kW electric sauna heater
• Heater output matched to the cabin volume
• Suitable for traditional dry sauna sessions and steam over the stones
• Harvia sauna stones included
• Designed to reach typical sauna temperatures in approximately 45 minutes under normal conditions

Actual heat-up times vary depending on ambient temperature, electrical supply, ventilation, initial cabin temperature and how frequently the door is opened.

Electrical Requirements

A fixed-wired single-phase electrical connection is required. No standard plug is supplied. Installation must be completed by a qualified electrician in accordance with current UK regulations, including Part P and BS 7671 where applicable.

Weather-Protected Shingle Roof

The KOVE Barrel Sauna features a black asphalt shingle roof designed to protect the timber cabin from rain and changing seasonal conditions.

The dark roof finish complements the natural Canadian Spruce, creating a timeless outdoor sauna that sits comfortably within a range of garden and patio settings.

• Black asphalt shingle roof
• Weather protection for year-round outdoor use
• Traditional appearance suited to gardens and patios
• Designed for permanent outdoor installation

8mm Tempered Glass Door

The entrance door is made from 8mm tempered safety glass, allowing natural light into the cabin while providing the strength and durability required for regular sauna use.

The clean glass finish complements the rounded timber structure and helps the interior feel brighter and more open.

The opposing internal benches provide seating for three to four adults while making efficient use of the cabin's width. The layout creates a welcoming, sociable environment without compromising access to the heater or entrance.

Assembly is typically completed by two to three capable people within a day, although timings vary depending on experience, access and site conditions. If you are not experienced in DIY, we recommend using a professional installer.

Delivery is kerbside only. Please ensure suitable access and adequate assistance are available to move the packaged components to the installation area. Please note that returns may not be accepted where an installation is faulty.

Outdoor Use, Timber Treatment & Maintenance

The KOVE Barrel Sauna is designed specifically for outdoor environments and is suitable for year-round UK use when installed and maintained correctly.

Like any premium timber outdoor structure, periodic inspection and appropriate exterior treatment will help preserve its appearance and maximise its service life.

• Inspect the external timber and roof periodically
• Keep the base area clear and well drained
• Avoid allowing standing water to collect beneath the sauna
• Reapply a suitable exterior timber treatment when required
• Clean the interior using products suitable for untreated sauna timber

Recommended Exterior Finish

We recommend applying a suitable exterior wood oil shortly after installation. Many owners choose Danish Oil to enhance the natural grain while adding protection from the elements.

Danish Oil will naturally deepen the colour of the timber over time. Alternative exterior oils, stains or paints may also be used depending on your preferred finish. The sauna is supplied untreated, allowing you to choose the finish that best suits your outdoor space.

Do not apply conventional paint, varnish or unsuitable chemical treatments to the internal benches or interior sauna surfaces.
