About

Maximum length, maximum light. Sauna 400 Deluxe matches the largest standard barrel length at 400cm but adds a tempered glass front, bringing genuine brightness into the curved interior. Solid Spruce construction keeps thermal performance intact behind the glazing. The most premium standard specification, suited to households who want both serious capacity and a more open, connected feel inside.

Combining maximum group capacity with the most elevated specification in the range gives households who want both genuine practical scale and premium finish a single, considered choice rather than a compromise between the two. The core physiological benefits of sauna bathing, improved circulation, reduced muscle tension, a cardiovascular effect comparable to light exercise, remain consistent regardless of finish, but the distinctive half-moon glazing brings substantial natural light into a sauna of this scale, which many users find enhances the overall relaxation experience considerably.

For households treating their sauna purchase as a serious long-term investment, choosing the most premium specification available within the standard barrel range often reflects a genuine commitment to making the sauna a centrepiece feature rather than a purely functional addition. That sense of pride in a well-specified, considered purchase tends to support more consistent, enthusiastic use over time.

The brighter, more open feel created by the substantial glazing also suits group sessions particularly well, since a connected, well-lit space tends to feel more sociable and inviting for a larger group than a fully enclosed cabin might. For households specifically planning regular, serious group entertaining around their sauna, this combination of maximum capacity and premium light makes for a genuinely standout garden feature.
Delivered flat-packed for self-assembly, with free UK mainland delivery on qualifying orders. The larger Cube format requires a little more assembly time than the smaller Icon models, so we recommend allowing a weekend and having a second person to help. A solid, level base and suitable delivery access are required.

For a complete setup, select Professional Installation and choose your preferred date, allowing for the stated production lead time. We’ll then arrange the installation around your requirements, including any additional preparation or works needed to accommodate your sauna where possible.

Electric sauna heaters require a suitable dedicated electrical supply and are not simply plug-and-play. The power requirements depend on the heater's output and the electrical supply available at the property.

Smaller heaters may be suitable for a 230V single-phase supply, while larger or more powerful heaters can require a 400V three-phase supply. Single-phase power uses one electrical phase, whereas three-phase power distributes the load across three phases and is better suited to higher-powered equipment.

The correct supply will depend on the specific heater you choose, so the heater's electrical requirements should always be checked before installation.

Sauna heaters will normally need to be hard-wired into a correctly rated dedicated circuit with the appropriate cable, isolation and electrical protection. They should not be connected using a standard household plug or extension lead.

The final electrical connection should be completed by a suitably qualified electrician in accordance with the heater manufacturer's instructions and applicable electrical regulations. This is important for both safety and reliable operation of the heater.

If you're based in the Leicestershire area, we can arrange the electrical installation of your sauna heater for an additional fee. Please speak to our team if you'd like this included with your sauna.

Wood-fired sauna heaters do not require an electrical supply for heating, but they do require the correct installation of the stove, chimney, flue and surrounding heat protection.

The stove must be positioned according to the manufacturer's required safety distances from timber walls, benches and other combustible materials. Depending on the stove and sauna design, suitable heat shields or other non-combustible protection may also be required.

The floor beneath and immediately around the stove may also require suitable non-combustible protection, particularly where there is a risk of embers or hot material falling from the stove.

A suitable chimney and flue system must be installed to safely carry smoke and combustion gases outside the sauna. Where the flue passes through the roof, the correct insulated chimney components, roof flashing and heat-resistant protection should be used.

Correct ventilation is also important. A wood-fired stove requires an adequate supply of combustion air, while the sauna itself needs sufficient airflow to provide fresh air, circulate heat and allow moisture to escape.

When choosing the position of an outdoor wood-fired sauna, you should also consider where the chimney will discharge in relation to your house, neighbouring properties, windows, boundaries and outdoor seating areas.

Any applicable local requirements should be checked before installation, particularly where chimney positioning, smoke control or other restrictions may apply.

The Sauna 400 Deluxe needs the same fundamental barrel sauna care as other models in the range, with particular attention to the distinctive half-moon glazed end wall given its larger size and premium specification. After every session, leave the door open for twenty to thirty minutes to let the heat room dry out fully, preventing mould and staining on timber surfaces. Wipe benches down once cooled, and sand the interior lightly once or twice a year wherever group use creates the most contact wear.

The half-moon glazing needs careful, regular cleaning with a standard glass cleaner and soft cloth, given its distinctive curved shape and prominent visual role; check for condensation build-up after sessions and wipe down before closing up.

Externally, treat the curved Spruce exterior with a wood treatment every two to three years, budgeting considerable time for this large, premium structure. Keep the full extended base clear of debris and standing water, checking drainage around the glazed end particularly carefully given its distinctive shape and the additional weight this premium model carries.
This sauna comes with a 5 year warranty for residential use and 2 years for commercial use, covering structural timber, glazing, and hardware. Valid claims are assessed case by case, and we'll supply replacement parts wherever possible rather than the whole sauna.
Production takes 10-12 weeks, plus 1-2 weeks dispatch time for pallet haulage. This sauna is delivered flat packed unless otherwise stated. Free UK mainland shipping applies to orders over £500 covering up to one double pallet (2.4m x 1.2m x 2.2m) or two single pallets (1.2m x 1.2m x 2.2m). Given this model's size and weight, additional pallet charges may apply and will be quoted separately based on your postcode, and forklift unloading may be required as it exceeds normal tail-lift limits (1000kg). Please have a solid base, clear access, and suitable unloading space ready before delivery, with help on site if needed. Pallet deliveries are kerbside only, and you're responsible for moving goods onto your property.

Barrel Sauna 400 Deluxe — Half-Moon Glass Spruce Sauna, 4m — spruce — side view 1

Maximum capacity, maximum specification

Sauna 400 Deluxe matches the 400 centimetre length of the standard largest model but adds tempered glass to the front of the structure, bringing natural light into the barrel format in a way the standard fully enclosed version does not offer. Solid spruce construction continues throughout the rest of the build, with the glazing positioned to maximise the view out while the curved barrel shape behind it keeps thermal performance properly intact.

The combination of maximum length and a glazed front makes this the most premium specification within the standard barrel sauna range, suited to households who want both the largest group capacity and a more open, connected feel from inside the sauna itself. Tempered glass is heat treated to withstand the repeated thermal stress a sauna front faces, heated air against cold air every time someone moves in or out during a session.

Sauna 400 Deluxe suits anyone who has decided that both scale and a brighter, more open interior matter to their overall sauna experience, delivering the largest standard capacity available alongside a finish that feels distinctly more considered than the fully enclosed barrel saunas elsewhere in the range. It represents the top of the standard barrel range in every sense that matters, length, finish, and overall presence in the garden.
