Kove 5-6 Person Spruce Cube Sauna with Front Porch & 8kW Harvia Electric Heater | KOVE-CUBE6

Premium Outdoor Sauna with Genuine Harvia Heater

Create your own outdoor wellness space with the KOVE Cube Sauna – 5–6 Person, a premium traditional outdoor sauna designed for spacious shared sessions, authentic heat and year-round UK use.

Crafted from premium Canadian Spruce and supplied with a genuine Harvia 8kW electric sauna heater as standard, the KOVE Cube combines authentic sauna performance with contemporary architectural design. Its generous interior, panoramic glazed frontage and concealed waterproof roof system make it equally suited to private gardens, luxury homes and professional wellness environments.

Contemporary Cube Design, Maximum Interior Space

The cube-style construction maximises usable interior volume, providing generous bench seating and excellent headroom without increasing the overall footprint. Straight walls create a spacious, comfortable environment for larger groups, while the large glazed frontage allows natural light into the cabin for a bright, relaxing sauna experience.

Its clean, self-supporting structure avoids unnecessary external banding and bulky trims, creating a refined architectural appearance that complements both traditional and contemporary outdoor spaces.

• Comfortably accommodates 5–6 adults
• Excellent headroom and generous bench seating
• Panoramic glazed frontage for a bright interior
• Clean architectural styling with no visible exterior banding

Crafted from Premium Canadian Spruce

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

Canadian Spruce helps create the bright, calming interior associated with Nordic-style saunas while providing excellent durability for long-term outdoor use throughout the changing British seasons.

• Solid Canadian Spruce construction
• Excellent natural insulation and heat retention
• Strong structural stability
• Smooth internal bench seating
• Premium timber finish for residential and professional settings

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 Cube Sauna – 5–6 Person is supplied with a genuine Harvia 8kW electric sauna heater as standard.

Designed by Harvia, one of Finland's most respected sauna brands, the heater delivers reliable performance, excellent heat distribution and the authentic stone-heated sauna experience that has made Harvia trusted worldwide for more than 70 years.

• Genuine Harvia 8kW electric sauna heater
• Powerful, even heat distribution for larger sauna cabins
• Suitable for traditional dry sauna sessions and steam over the stones
• Designed to reach typical sauna temperatures in approximately 45–60 minutes under normal conditions

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

Outdoor Use, Timber Treatment & Maintenance

The KOVE Cube 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 exterior treatment will help preserve its appearance and maximise its service life.

• Inspect external timber and roof periodically
• Keep the base area well drained
• 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 customers choose Danish Oil, which enhances the natural grain while adding protection from the elements.

Please note that 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. Because appearance is a personal choice, the sauna is supplied untreated.

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