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.
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
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.
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
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
For customers who prefer a premium brand upgrade, the sauna can also be specified with a Harvia electric sauna heater for £199. This option can be selected from the dropdown below the add to cart.

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.
