Premium Outdoor Sauna for Home & Professional Wellness
Create a refined outdoor wellness space with the KOVE Cube Sauna – 5–6 Person, a premium outdoor sauna engineered for powerful performance, clean architectural design, and long-term outdoor use.
Designed as a true step up from entry-level cube saunas, the KOVE Cube focuses on build quality, internal space, and weather protection — delivering a consistent, authentic sauna experience for shared sessions in gardens, wellness spaces, and professional environments.
Modern Cube Design for Maximum Interior Space
The cube-style construction maximises usable internal volume, offering generous bench space and excellent headroom for comfortable group sauna sessions.
Unlike cheaper cube saunas that rely on visible banding, bolt-on trims, or external framing, the KOVE Cube features a clean, self-supporting structure with no exterior banding. The result is a more refined appearance and a sturdier, longer-lasting build.
Spacious seating layout for 5–6 people
Excellent headroom and bench depth
Clean-lined exterior with no visible banding
Solid Spruce Wood Construction
Crafted from high-quality spruce wood, the KOVE Cube Sauna delivers excellent insulation, structural stability, and long-term outdoor durability. Spruce is widely used in traditional sauna construction thanks to its heat retention, resistance to temperature change, and natural finish.
Smooth internal bench seating designed for longer sessions
Large 8mm tempered safety glass front for strength, insulation, and visibility
Premium timber finish suited to residential and professional settings
Natural variations in wood grain and colour are normal and part of the sauna’s character.
Weather-Protected Roof Built for UK Outdoors
Unlike lower-cost cube saunas that rely on exposed asphalt shingles or felt roofing, the KOVE Cube features a concealed waterproof membrane beneath the roof slats. This provides dependable protection from rain and moisture while keeping the roofline clean and architectural.
Waterproof membrane hidden beneath roof slats
No exposed felt or asphalt shingles
Designed for year-round UK outdoor use
Powerful 8kW Electric Sauna Heating
The KOVE Cube Sauna – 5–6 Person is supplied with a 8kW KOVE professional-grade electric sauna heater as standard, delivering strong, stable heat output suitable for shared sessions and frequent use.
8kW heat output ideal for 5–6 person cube cabins
Even temperature distribution throughout the cabin
Typical heat-up time of approximately 45–60 minutes, depending on ambient conditions
Harvia Heater Upgrade (+£199)

Recommended Finish on Installation (Exterior Only)
We recommend applying a suitable exterior wood oil on installation (exterior only). Many customers choose Danish oil, which deepens the wood tone over time.
Other oils, stains, or finishes can be used depending on your preferred aesthetic — and some customers even choose to paint their sauna. Because finish preference is personal, the sauna is supplied untreated.
Is a Cube Sauna Right for You?
A cube sauna is an excellent choice if you’re looking for:
A modern, architectural sauna design
Maximum internal space without external features
A premium alternative to asphalt-roof cube saunas
A high-capacity sauna for shared or professional use
Reliable performance in all seasons
If you prefer a more traditional look with curved airflow and a porch area, a barrel sauna may suit you better. If clean aesthetics, internal space, and build quality are the priority, the Cube is the ideal choice.

The Fonteyn Barrel Sauna Rustic Red Cedar is one of the most naturally beautiful and practically built outdoor barrel sauna UK options available today. Crafted from genuine western red cedar outdoor sauna-grade timber, this is a wood that is naturally resistant to moisture, warping, and decay, making it genuinely well-suited to year-round outdoor use in the UK climate without constant maintenance or treatment. The distinctive garden sauna barrel shape is not just for looks, either. The curved structure allows heat to rise and circulate evenly throughout the cabin, meaning it reaches temperature faster and holds it more consistently than a standard box-shaped unit of the same size.
Available in sizes from 4ft through to 8ft, the Fonteyn barrel sauna with heater included gives you a complete Finnish barrel sauna for home use straight out of the box without needing to source heating separately. Whether you are setting it up as a standalone indoor or outdoor sauna barrel in a garden, on a patio, or in a sheltered outbuilding, this red cedar barrel sauna is built to deliver the real traditional sauna experience that more basic flatpack units simply cannot match. From the rich natural scent of the cedar wood to the efficient, even heat, every session feels exactly how a proper sauna should.
