Residential / commercial
ARDNA 3 | Three person sauna cabin | From £34,500 exc. VAT01 | THE ORDINARY USE
A WET TUESDAY IN FEBRUARY
The first weekend is easy to picture. The ninety-third session is the one that decides whether a sauna was worth building.
It is dark by half four. You light the stove on the way past, go back inside, and come out forty five minutes later in a towel and boots. Two of you, sometimes three. Nobody has arranged anything. You sit, you throw water, you go out into the cold, you come back in. An hour later the house is quiet and you sleep properly.
That evening is the whole product. Everything below exists to make it repeatable in bad weather, at short notice, for years.
One Ardna owner puts it more plainly than we would: “It's getting used every other day. It's so uplifting.”
02 | IS THIS THE RIGHT ONE
THE ARDNA, 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.
It will usually be one, two or three of you, and often just you.
You want it lit on a weeknight, not saved for special occasions.
The plot is tight, overlooked, or awkward to reach.
You want the least groundworks and the smallest lift we build.
THE ARDNA MAY BE FOR YOU IF…
You want to lie flat. The internal width is 1,350m This is a sauna for sitting. Look at the Mara 4.
There will regularly be four of you. The Ardna is designed to seat two on the top bench, and one on the bottom. Look at the Mara 4
You want a different design. We have curated a distinct range of sauna designs, each inspired by their own unique philosophy. Explore the Mara or Cove range.

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.

07 | THE QUESTIONS THAT STALL PEOPLE
ASKED BEFORE EVERY ORDER
-
Seated, three. Two on the top bench, one on the bottom. The Ardna is 1350mm wide, so an adult will not lie flat. If lying down matters to you, explore the Mara 4.
-
Your groundworks, electrician, any planning application and the installation fee which will vary by location - we can advise this quickly once we have your enquiry
-
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.
-
Designed in Scotland. Manufactured in Europe with long-established specialist timber partners, chosen for expert craftsmanship, consistency, precision and material control. It arrives fully prefabricated.
-
Each Doon sauna comes with a five years structural warranty., and a two year year warranty on fixed components: glazing, doors and benches. The stove warranty is provided by the manufacturer
