Description

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

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)

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.

Electrical Requirements

Fixed-wired connection required. No standard plug supplied. Heater installation must be carried out by a qualified electrician in accordance with UK regulations (Part P / BS 7671).

Features

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

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.

Ideal For

Outdoor garden and patio sauna installations
Shared home wellness and recovery routines
Post-workout recovery and contrast therapy
Hotels, gyms, studios, and wellness centres
Year-round outdoor sauna use

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.
