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?
Five footprints, from 160 × 120 cm for the Slim Two to 340 × 220 cm for the Six. The Three, Four and Six come 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.

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.
- Every electric cabin is sold on its own; you add the Harvia heater in the build.
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 electric barrel is sold on its own; you add the Harvia heater in the build.
Same size: the electric Barrel Four is £2,795 and the electric Cabin Four £4,346, both without a heater and with mainland delivery in the price.
How is an electric sauna heated?
A Harvia heater on a timer, on its own circuit from your consumer unit: 35 A for the PC70.
Electric- The Harvia Cilindro PC70, 6.8 kW, is in the price of every electric cabin and barrel except the Cabin Three, sold as the cabin only: add the PC70 or PC70E in the build.
- The Slim Two and Slim Two XL have the Harvia Vega BC60, 6 kW, in the price.
- The Cabin Six and the Barrel Four and Six can take the 9 kW PC90 instead: it needs a 40 A supply.
- Timer and thermostat on the heater. Stones are extra: 20 kg boxes at £69.
- Its own circuit from your consumer unit, 35 A for the PC70, by a qualified electrician: not in the price.
Yes. Every electric sauna needs its own circuit from your consumer unit: 35 A for the PC70 and the BC60, 40 A for the PC90. A qualified electrician installs and certifies it under Part P; it is not in our price. Ask for the quote before you order: each electric page has a sheet with what they need.
Only while the heater is on: 6.8 kW at full power for the PC70, 6 kW for the BC60, nothing on standby. What an evening costs depends on your tariff and how long you keep the room hot.
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 Harvia PC70 or BC60 and UK mainland delivery, on every electric sauna except the Cabin Three, sold as the cabin only. 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.
The Slim Two and Slim Two XL are a narrower build: solid timber walls, a full-height glass door, solid timber boards over the curved top; the Harvia Vega BC60 is a choice in the build.
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, your electrician 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.
Its own circuit from your consumer unit, 35 A for the PC70 (40 A for the PC90), installed and certified under Part P.
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.
Sold without a heater, for one you already have, or add the PC70 (£449) or PC70E (£519) in the build. Its delivery is £545 to the mainland.
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 the heater circuit.
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.
35 A for the PC70 and the BC60, 40 A for the PC90, from your consumer unit. Each electric page has a sheet with what your electrician needs; get the quote before you order.
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. UK mainland delivery is in the price of every sauna except the electric Cabin Three.
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; mainland delivery is in the price of every sauna except the electric Cabin Three (£545).
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 (the electric Cabin Three: £545); 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?
Waldenhaus Limited, a UK company: 14 days to report damage, a 2-year warranty, parts for 10 years.

|---|---|---|---|
| It arrives damaged or short | Note it on the delivery note, take photos and email us within 14 days of delivery. We replace damaged or missing parts free of charge, delivery included. | 14 days | We pay |
| A part fails | A 2-year warranty against manufacturing and material defects, from the day of delivery, on the sauna and everything supplied in the crate, as long as the outside is treated again at least every two years. Parts, not a new sauna: we send the board, fitting or panel that is needed. | 2 years | Part free |
| The heater fails | Harvia’s own warranty as well as ours: 2 years for home use, plus 1 year if you register it with Harvia within 30 days. Harvia requires the connection to be made by a qualified electrician. | 2 + 1 years | Harvia |
| You need a part later | We keep replacement parts for 10 years from your purchase date. | 10 years | You pay |
| You change your mind | 14 days from delivery to cancel and a further 14 days to send it back, unused and in its crate. Return is by pallet freight, which you arrange: typically £150 to £250 from a UK mainland address. | 14 days | Pallet yours |
The saunas follow the same Waldenhaus standard as our greenhouses: published dimensions taken from the factory drawings, a clear price for the build you choose, and a photo of the packed crate requested before it ships.

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.
It is built as an outdoor sauna: solid timber walls, no added insulation; treat the outside before its first winter. Plan for the heater. Where it drops below 0 °C, Harvia does not recommend the heaters we fit for an outdoor sauna without background heating. The PC70, PC90 and BC60 have a mechanical thermostat: Harvia says its overheat cut-out can trip when the air around the heater is below −5 °C, and it resets only once the room is back above +18 °C. The PC70E and PC90E have electronic control, which Harvia says is less sensitive to the cold, but as pillar heaters with a large stone load they warm a cold room slowly.
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.
