What should you know before you choose?
The range in six numbers, then every answer on this page: pick a question to jump to it.
Which size fits your garden?
Three footprints, from 185 × 220 cm for the Three to 340 × 220 cm for the Six. Each comes as a cabin or a barrel on the same footprint.
Drawn to one scale: each outline is the sauna on the ground, seen from above. The cabin and the barrel of one size stand on the same footprint.
3 people · 185 × 220 cm · 4.1 m²
- Cabin hot room 206 × 155 cm, an L-shaped bench, 210 cm long
- Barrel hot room 175 cm long, two benches facing
- Crate 2.4 × 1.2 × 1 m
4 people · 240 × 220 cm · 5.3 m²
- Cabin hot room 206 × 175 cm, benches 174 × 55 cm facing, a porch
- Barrel hot room 175 cm long, benches 174 × 50 cm facing, porch seats
- Crate 2.4 × 1.2 × 1 m; wood-fired, the stove on a second pallet
6 people · 340 × 220 cm · 7.5 m²
- Cabin two tiers and a side bench, hot room 206 × 185 cm, an 85 cm changing room, a porch
- Barrel hot room 185 cm long, benches 184 × 50 cm facing, an 85 cm changing room, a canopy
- Crate 3.4 × 1.2 × 1 m
185 × 220 cm on the ground, 4.1 m². Hot room 206 × 155 cm. L-shaped alder bench, 55 cm deep. Up to three people.
240 × 220 cm on the ground, 5.3 m². Hot room 206 × 175 cm. Benches on both side walls, 55 cm deep, two a side.
340 × 220 cm on the ground, 7.5 m². Hot room 206 × 185 cm and a changing room 85 cm deep. Two tiers and a side bench, up to six people.
340 × 220 cm on the ground, 7.5 m². Hot room 185 cm long with two benches 184 × 50 cm facing, and an 85 cm changing room with two storage benches. Two glass doors.
Seated, as the number says: three in a Three, two on each bench facing in a Four, six in a Six on two tiers in the cabin or three a side in the barrel. The Slim Two is a narrow cabin for two. Size for the people who will use it every week; if you have never kept a sauna habit, try a month at a local gym first.
Cabin or barrel: what is the difference?
The same footprints, the same seats, the same heaters and stoves. The shape changes the room inside, the look in the garden and the price.
The cabin- Hot room 206 cm across: 155 cm deep in the Three, 175 cm in the Four, 185 cm in the Six.
- Alder benches 55 cm deep: an L-shape in the Three, two facing in the Four, two tiers and a side bench in the Six.
- A porch on the Four and the Six; the Six adds an 85 cm changing room. About 2.4 m tall.
- The stove and flue kit are in the price of every wood-fired cabin.
The barrel- Hot room 206 cm across: 175 cm long in the Three and the Four, 185 cm in the Six.
- Two alder benches facing, 50 cm deep, with backrests on the curved wall.
- Porch seats on the Four; a canopy and an 85 cm changing room on the Six. Under 2.5 m tall.
- Round walls of solid boards held by steel straps, shingles over the top. Every wood-fired barrel has its stove and flue kit in the price.
Same size, same stove: the wood-fired Barrel Four is £3,699 and the wood-fired Cabin Four £4,999, both with the stove, flue kit and mainland delivery in the price.
How is a wood-fired sauna heated?
A wood-burning stove with its flue kit, in the price of every wood-fired sauna. No heater circuit to arrange.
Wood-fired- The stove and its flue kit are in the price of every wood-fired cabin and barrel, with UK mainland delivery.
- No heater circuit needed. The stove is fed from outside the hot room, except in the Cabin Four, where you feed it from the room.
- The flue goes up through the roof. In England and Wales, fitting a stove and flue is building work under Part J: building control, or a registered installer.
- The stove is not on Defra’s exempt-appliance list: in a Smoke Control Area you cannot burn wood in it. Each wood-fired page has a postcode check.
Not with wood: the stove is not on Defra’s exempt-appliance list. Councils declare their own smoke control areas, street by street, so check your address with your council first, or use the postcode check on any wood-fired page. If your street is in one, the electric sauna of the same size is the one to choose.
In England and Wales, fitting a stove and flue is building work under Part J: tell building control, or use a registered installer. The flue kit, the stove stand, the stone guard and the heat shields come in the crate; a non-combustible plate under the stove is yours.
What exactly do I get?
The whole sauna, flat-packed, with every fixing bagged by size. The pages of the Threes, Fours and Sixes list every part, with photos.
Solid timber boards: straight walls on the cabins, round walls on the barrels, held by steel tension straps. No glued sandwich panels and no PIR boards anywhere.
1770 × 690 mm, in a timber frame with a timber handle. The Sixes have two: into the changing room, then into the hot room.
55 cm deep in the cabins, 50 cm in the barrels: an L-shape in the Cabin Three, two tiers in the Cabin Six, two facing in the others.
Bitumen shingles: sealed along the edges on the cabins, nailed in rows over the top of the barrels.
Tensioners keep the walls tight as the timber moves: tighten them evenly in a dry summer and ease them a little in autumn.
Bare timber on arrival. Treat the outside before the first session and the first winter, then at least every two years. We do not supply the finish in the UK: any DIY shop sells it.
The stove, its flue kit and UK mainland delivery, on every wood-fired sauna. Stones are extra.
Flat-packed in a timber crate, wrapped and banded: 2.4 m long for the Threes and Fours, 3.4 m for the Sixes. A wood-fired Four’s stove comes on a second pallet.
Yes. The pages of the Threes, Fours and Sixes list every part from the factory manual, down to the fixings, with photos, plus what stays your job on site. Before it leaves, we ask the works for a photograph of your packed crate with its packing list and pass it on to you.
Yes, with every step drawn. Read it before you order: The Cabin Three · The Cabin Four · The Cabin Six · The Slim Two · The Barrel Four · The Barrel Six (PDF).
What else will I pay for?
Stones, a base, the flue fitting and the exterior finish. A surcharge outside the mainland shows by postcode before checkout. Nothing is added after you pay.
In 20 kg boxes, added in the build before checkout: the PC70 basket takes up to 80 kg, the BC60 20 kg.
A pad the size of the footprint, level and square, with free drainage under the floor drain: slab, paving or compacted gravel.
Building work under Part J in England and Wales, by building control or a registered installer.
Any exterior preservative or stain, outside only: before the first session and the first winter, then at least every two years. Any DIY shop sells it; leave the inside untreated.
Isle of Wight +£49, Scottish Highlands +£79, Northern Ireland +£99, Scottish islands +£149, shown before checkout. The Isle of Man: contact us before ordering.
We do not offer assembly; a local joiner can quote from the manual. UK sellers charge £900–£1,000 to assemble a garden sauna like this.
No. Everything you pay us is priced in the build before the basket: the sauna, the heater if you add one, stones, extras and delivery to your postcode. Nothing is added at checkout, and not a penny more after you pay. What sits outside our price is listed here: a base, your electrician or the flue fitting, the exterior finish.
Yes, before delivery. Ask your insurer whether your policy covers the sauna and its heater or stove, and which installation documents they need. A garden building of this value can sit above the outbuildings limit on a standard policy.
Will it suit your plot?
Four checks before you pay: the footprint and base, the route in from the kerb, planning and, for a wood-fired sauna, smoke control.
A level pad the size of the footprint, 160 × 120 to 340 × 220 cm, no bigger: a slab that sticks out past the wall holds rain against it. No water connection; the floor drain empties under the sauna, so the base needs free drainage.
The crate stops at the kerb. Plan for two people and a sack truck: the wall boards are about 2.35 m long and the end panels nearly as wide as the sauna. Check the side gate, the corners and any steps.
Usually permitted development in England and Wales: these saunas cover 1.9 to 7.5 m² and stand under 2.5 m tall. Height, distance to a boundary, conservation areas, listed settings, flats, Scotland and Northern Ireland change it.
Councils declare their own smoke control areas, street by street, and the stove is not on Defra’s exempt-appliance list. Electric has no flue, so this matters only for a wood-fired sauna.
Close to the house: you walk back from it in a towel. Face the glass door to the fence or the house, not the street, and leave room to walk round it and to reach the straps.
No. There is no water connection: you bring a pail of water in for the stones. Water that reaches the floor drains through it beneath the sauna, so the base needs free drainage.
It is designed to be built once. Taking it down and rebuilding it is not provided for, so plan the site as permanent.
How does it get to your kerb?
Made to order, one crate to your kerb in 2 to 4 weeks, with UK mainland delivery in the price.
Each sauna is made to order in about ten days. Before it leaves, we ask for a photograph of your packed crate with its packing list and pass it on to you.
Our carrier calls to book the day, so that you can be there to check the crate. Order to kerb is typically 2 to 4 weeks on the UK mainland, with mainland delivery in the price.
The crate comes by lorry and is set down at the kerb, on the nearest hard, level standing: driveway or road, not grass, gravel or a slope. The lorry needs room to stop there. The driver does not carry it into the garden.
Note any damage on the delivery note and take photos, then count the parts against the packing list. Email us within 14 days and we replace damaged or missing parts free of charge, delivery included.
Delivery by area: UK mainland in the price; on top of it, Isle of Wight +£49 · Scottish Highlands +£79 · Northern Ireland +£99 · Scottish islands +£149 · Isle of Man: contact us before ordering · Channel Islands, Isles of Scilly and BFPO not served. The figure for your postcode is the one checkout uses.
Can we build it ourselves?
Yes: two people, ordinary tools and the factory manual, which draws every step.
by building it yourselves: that is what UK sellers charge to assemble a garden sauna like this. Published fitting prices for garden saunas, September 2026. We do not offer assembly, for any sauna; a local joiner can quote from the manual.
Read the manual before you order- Every wall board is pre-cut and numbered: the walls go up board by board, in order.
- Steel straps pull the shell tight; the fixings come bagged by size.
- The manual draws every step, with ordinary tools.
- Cabins: two people typically build one in a weekend. Barrels: the factory allows 8 to 12 hours for two people, with some cutting: the last wall boards are trimmed to fit.
What if something goes wrong?

Will it leak, rot or go mouldy?
Not if four jobs are done: treat the outside at least every two years, look the roof over each spring, adjust the straps with the seasons and air it after every session.
Any exterior preservative or stain, outside only: before the first session and the first winter, then at least every two years. The warranty asks for it; leave the inside untreated.
Each spring, look the shingles over: the sealed edges on a cabin, the rows over the top of a barrel. Fix down any that have lifted.
Timber swells in damp weather and shrinks when it is dry: tighten the straps evenly in a dry summer and ease them a little in autumn.
Leave the door ajar and the vent open until the room is dry. If it is rarely used, air it on a dry day every few weeks.
Yes. It is built as an outdoor sauna: solid timber walls, no added insulation. Treat the outside before its first winter, keep the logs dry and have the flue swept at least twice a year.
We do not put a number of years on it. The written warranty is 2 years and we keep parts for 10; the rest is the four jobs above: treat, check the roof, adjust the straps, dry.
We sell the sauna and do not give medical advice. If anyone in the household is pregnant or has a heart or blood-pressure condition, ask a GP before using any sauna. Keep children away from the heater or stove, and do not leave them alone in the hot room.
