Mara 4
Our three person sauna. Wood fired or electric. Made for gardens, coastal plots and small ground.
Residential / commercial
MARA 4 | Four person sauna cabin | From £37,000 exc. VAT01 | THE ORDINARY USE
FOUR SITTING, OR TWO FULL LENGTH
Two benches, one above the other, each 1800 millimetres long. Four people sit. Two people lie down, one to a tier.
1800 millimetres is five foot eleven. Most adults lie flat on it. If you are over six foot you will lie with your knees bent.
A large panoramic window runs the wall opposite the benches and frames the view.
02 | IS THIS THE RIGHT ONE
THE MARA, AND WHO SHOULD BUY SOMETHING ELSE
We would rather you bought the right model than the expensive one - not all of our sauna models will be right for you.
THE MARA MAY BE FOR YOU IF…
You want to lie down. The Ardna's bench is 1350 mm and is for sitting only. The Mara's is 1800 mm.
You want extra space for family and friends
SOMETHING ELSE MAY BE MORE SUITED IF…
It is usually one or two of you. You would be heating a four-person room for one person most times you use it, and that is the fastest route to an unused sauna. The ARDNA 3 is £3,000 less and smaller to heat.
The site takes serious wind. The Mara's roof oversails on all four sides, and an overhang that size catches wind rather than shrugging it off. On an exposed coastal or upland plot you want a low profile and a tight silhouette instead.

04 | THE STANDARD
THE DETAILS THAT MAKE A DOON SAUNA
01
NOTHING THAT OFF-GASSES
Inside the sauna envelope we use no glues, resins, silicones or synthetic sealants. Insulation is sheep's wool without polymer binders, so the wall handles moisture rather than being sealed against it.
02
OPENINGS THAT STAY TRUE
Doors and windows are handmade from Accoya, one of the few timbers that performs reliably through repeated heat cycles. Accoya carries a fifty-year warranty on the timber. Frames stay true. Seals remain tight.
03
SURFACES THAT TAKE THE HEAT
Interiors are lined in thermo-treated aspen: low resin, stable, calm to touch at full heat. Floors are porcelain tile with stainless drainage. Fixings are marine stainless.
04
VENTILATION AS ONE SYSTEM
Fresh air enters low, passes the heat source, and leaves cleanly. Bench heights are set to put you in the band where temperature is consistent and circulation is balanced.
05
LIGHT YOU DON'T LOOK AT
Downlighting is concealed beneath the benches and uplighting behind the backrests. No overhead fitting, no glare, nothing to adjust
06
DESIGNED IN SCOTLAND, BUILT IN EUROPE
We develop the form, proportions and performance details in Scotland. Manufacture is with long-established specialist timber partners in Europe, chosen for expert craftsmanship, consistency and material control.
05 | YOUR SIDE OF THE BUILD
four THINGS ARE YOURS TO ARRANGE
The base
WE DO NOT OFFER GROUNDWORKS
We provide foundation and setting-out drawings covering footprint, levels, load points and tolerances, and your groundworker builds to them. Most people use a compacted stone base with concrete pads, ground screws or a poured concrete base. It must be complete, cured and level at least one week before installation.
AN ELECTRICIAN
SUPPLY AND ISOLATION ARE SEPARATE
The sauna arrives fully pre-wired internally. A qualified electrician provides the supply and, where regulations require it, a local isolation switch. Final connection happens once the structure is positioned.
ACCESS
IT ARRIVES FINISHED, ON A LORRY
These are delivered as complete prefabricated structures and typically placed by HIAB. We assess the route in advance. Some sites need a crane. The Ardna is the smallest lift in the range, which is often what makes a difficult plot possible.
Outdoor saunas often fall under permitted development. Often is not always. Size, proximity to boundaries, listed status, conservation areas and commercial use all change the answer, and we will not tell you that consent is unnecessary. At 2600 mm the Ardna is the lowest structure we build, which helps. Check with your local authority before you commit to a date.

06 | ORDER TO FIRST SESSION
WHAT HAPPENS, AND WHEN
01
SITE CHECK
A short call about access, base and power. We look at these before anything else, because a sauna sold into a site that cannot take it is a bad sale for both of us.
02
SPECIFICATION AND SLOT
Finish, stove type and details are confirmed within the core design. Price and build slot are fixed.
03
FABRICATION
Typically eighteen weeks from the start of fabrication. Your base is built during this period, to our drawings.
04
DELIVERY AND HANDOVER
The date is confirmed three weeks ahead. We place the structure, your electrician makes the final connection, and we hand over with guidance on use and care.
WARRANTY
Five years structural warranty. Two years on fixed components: glazing, doors and benches. Stove comes under manufacturers warranty.

Often not. Outdoor saunas frequently fall under permitted development, but it is not guaranteed. Size, proximity to boundaries, listed status, conservation area status and commercial use all change the answer. Check with your local authority before you order. We will not tell you that consent is unnecessary.
