The Finns have a word for the moment a sauna truly comes to life: löyly
It is the gentle wave of warmth and steam that rises as water meets the hot stones, softening the heat, calming the mind and changing the entire atmosphere around you.
It cannot be measured in degrees or captured in specifications. It is a feeling. A sense of stillness. A deeper connection to warmth and wellbeing.
Powered by authentic Finnish-built heaters, every H2O sauna is designed to create beautiful löyly, delivering the rich, enveloping heat that has defined the Finnish sauna experience for generations.
Free delivery & build
Free delivery and build of this Cube Mini sauna is offered to customers in selected areas covering much of England & Wales.

Why? Because the build can take up to 6 hours, when driving time is factored in the teams may require an overnight stop. We make this pricing transparent to be fair to all customers.

FAQs
Everything you might want to know about our saunas.
Do you deliver the Cube Mini sauna in my area?
We deliver our saunas all over the UK mainland... so if you live in England, Scotland or Wales then yes, we do!
Can you deliver with a crane?
We don't have a crane ourselves, but we can help you to source a crane for delivery over the top of your property or to an upper level.
How much space do I need for a sauna?
We recommend you have a minimum of 1m clearance around each side of the sauna for the build.
What ground work do I need for the Cube Mini?
We recommend a hard, flat ground with a poured concrete base that has been levelled off.
You can then add gravel, bark or anything else around this to create a decorative effect.
We can also install on patios (as long as they're flat) and decking if it it reinforced.
Speak to our friendly specialists if you're not sure.
Do I have to treat my sauna?
Yes. As it's made from a natural product, you'll need to stain it every 6 months to ensure it holds its colour. Otherwise, the colour made fade over time.
Do you connect the sauna to power and test?
No, we just build the sauna for you. Our team are not qualified electricians.
Your electrician will need to complete the wiring and connect it to your supply.
About the Cube Mini sauna
The Cube Mini sauna is a compact, traditional electric outdoor sauna for one or two people. Its rounded corners and glass front give it a clean, contemporary shape that suits smaller gardens, patios and courtyards. The cabin measures approximately 134 cm wide × 153 cm deep × 222 cm high and comes in two colours, Black or Natural wood.
The cabin is built from thermo-spruce, a heat-treated timber chosen for its stability outdoors. Fixed glazed panels sit alongside an 8 mm grey tempered-glass door, bringing daylight into the cabin and giving you a view of the garden from the bench. Bitumen shingles cover the roof, and timber foundation bearers support the cabin.
Inside, the two-tier bench, backrest and floor are made from thermo-aspen. This heat-treated timber has a smooth, resin-free surface that feels comfortable against bare skin. Two dimmable warm LED strips sit above the backrest and beneath the upper bench. Use the supplied remote to adjust the lighting for daytime or evening sessions.
The Cube Mini sauna is designed for the Harvia The Wall electric sauna heater, with 6 kW recommended and a 9 kW option. The heater mounts to the wall to keep the floor beneath it clear. For a traditional sauna experience, use the ladle to pour a little water over the heated sauna stones. This releases a brief burst of steam known as löyly. Heater supply depends on the package selected.
The sauna cabin is supplied in a plywood crate for assembly on site. It includes the glazing, bench and backrest, LED lighting and remote, roof shingles and timber foundation bearers. The included accessory kit contains a water bucket, ladle, thermometer, hygrometer and sauna timer.
Choose a firm, level base with enough room for the door to open fully and for access during assembly and maintenance. A qualified electrician should install a dedicated electrical supply sized for the selected heater.
