That is 5.3 m² on the ground, under 2.5 m tall. A firm, level base is all it needs: slab, paving or compacted gravel; the three cradles sit on it.

The PC70 is in the price. Harvia rates it for rooms of 6 to 10 m³ and the PC90 for 8 to 14 m³. The PC90 heats the barrel faster. The PC90 needs a 40 A supply instead of 35 A. The dedicated supply and final connection by a competent electrician are not included.

What does your garden need for an electric barrel sauna?

Four checks, all before you pay. For the electric barrel the one that decides it is the circuit from your house.

4Delivery and build

How is the barrel sauna kit delivered and built?

Made to order, one crate to your kerb in 2 to 4 weeks, then two people, ordinary tools and a manual that draws every step.

1Made to order

Your barrel 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.

2The day is booked

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. A few postcodes carry a surcharge: chapter 3 shows yours.

3Set down at the kerb

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 the crate into the garden.

4Check before you sign

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.

£900–£1,000

by building it yourselves: that is what UK sellers charge to assemble a garden sauna like this. The factory allows 8 to 12 hours for two people to build The Barrel Four, with some cutting: the last wall boards are trimmed to fit.

Published fitting prices for garden saunas, September 2026. We do not offer assembly, for any sauna; a local joiner can quote from the manual.

The crate stops at the kerb. Plan for two people and a sack truck, and walk the route to the plot first: a side gate, a corner, a step.

The wall boards are 2.35 m long: a corner or a step needs a look.
The end-wall panels are nearly as wide as the barrel: check the gate first.
87 wall boards, pre-cut and numbered: carried a few at a time.
Before the crate arrives: the base
Pad the size of the footprint: 240 × 220 cm, no larger. A slab that sticks out past the wall holds rain against it.
Level and square: the three base cradles go down level, 810 mm apart; measure both diagonals and make them equal.
No water connection, free drainage: no mains water is needed; the floor drain empties under the barrel.
Concrete slab, paving slabs or compacted gravel: whichever you choose, the barrel brings its own floor and base cradles.

6Care and upkeep

How do you care for a timber barrel sauna?

Four jobs matter: treat the outside before the first session and leave the inside untreated, look the shingles over once a year, tighten the straps a month after the build and then once a year, and after each session 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.

The Barrel Four from the side: the shingle roof, the steel straps and the base cradles
What keeps water out

71 shingles over the top of the barrel.

What you do

Nail them on during the build, then check them yearly.

Bitumen shingles in rows along the roof edge1 / 2
Will rain get in?
Bitumen shingles, nailed on in rows over the top of the barrel.

You nail them on during the build; the manual shows the rows and the nails. Look them over once a year and fix down any shingle that has lifted. Damp inside after a session is condensation from the steam: leave the door and the vent open until the room is dry.

Parts for ten years

We keep replacement parts for 10 years from your purchase date: a board, a fitting, a panel.

How long will it last?

We do not put a number of years on it. The written warranty is 2 years; the rest is the four jobs above: treat, tighten, check the roof, dry. The boards swell in wet weather and shrink in dry, which is why the straps are checked every year; if a board or a fitting fails, we send the part.

?FAQ

Questions about this barrel sauna

Pick a subject, or type it.

Is four people realistic?

⌄
Yes, seated. Two on each bench, facing each other across the aisle, with the heater on the back wall between them. Each bench is 174 cm long and 50 cm deep, at one height, with a backrest on the curved wall. The porch seats outside are for cooling off between rounds.

Do I need planning permission?

⌄
Garden buildings are usually permitted development in England and Wales; this barrel covers 5.3 m² and stands under 2.5 m tall. Height, distance to a boundary, conservation areas, listed settings, flats, Scotland and Northern Ireland all change the answer. Check the Planning Portal and your council before you order.

Should I tell my home insurer?

⌄
Yes, before delivery. Ask your insurer whether your policy covers the sauna and its heater, and which installation documents they need. A garden building of this value can sit above the outbuildings limit on a standard policy.

Where in the garden should it go?

⌄
Close to the house: you walk back from it in a towel. Face the glass door and the porch to the fence or the house, not the street; the matt-glass door option shows less of the room. Leave room to walk round it and to reach the straps.

Can I use it through a British winter?

⌄
Yes, it is built as an outdoor sauna. The walls are solid timber without added insulation, and we have not yet measured how it heats up in winter. The two jobs that matter first are the exterior treatment before the first season and the strap check after the first month.

Does it use a lot of electricity?

⌄
Only while the heater is on: 6.8 kW at full power for the PC70, nothing on standby. What an evening costs depends on your tariff and how long you keep the room hot.

Is the heater included?

⌄
Yes. The Harvia Cilindro PC70, 6.8 kW, is in the price, with its timer and thermostat on the heater; Harvia rates it for rooms of 6 to 10 m³. Stones are not: the basket takes up to 80 kg, added in boxes of 20 kg. The heater circuit is your electrician’s job: ask for the quote before you order.

What does delivery cost?

⌄
Kerbside delivery to the UK mainland is in the price. The Isle of Wight is +£49, the Scottish Highlands +£79, Northern Ireland +£99 and the Scottish islands +£149, shown by postcode before checkout. For the Isle of Man, contact us before ordering; the Channel Islands, the Isles of Scilly and BFPO addresses are not served.

Does it need a water supply?

⌄
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 barrel, so the base needs free drainage.

What exactly is it made of?

⌄
Solid timber boards for the round walls and the end walls, alder benches, an 8 mm toughened glass door. No glued sandwich panels and no PIR boards anywhere in the build. It ships untreated: the exterior finish is yours to choose.

What about children and the heater?

⌄
Keep children away from the heater, and do not leave them alone in the hot room.

Is a sauna safe for everyone?

⌄
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.

Can I take it with me if I move house?

⌄
It is designed to be built once. Taking it down and rebuilding it is not provided for, so plan the site as permanent.

Electric or wood-fired?

⌄
Same barrel. Electric heats on a timer and needs its own circuit: 35 A for the Harvia PC70. Wood-fired needs no heater circuit, but does need a flue through the roof and cannot burn wood in a Smoke Control Area: the stove is not on Defra’s exempt-appliance list, so check your address with your council first. If your electrician’s quote is the sticking point, look at the wood-fired build.

What if it arrives damaged or short?

⌄
Check the delivery before the driver leaves. Note any damage on the delivery note and take photos, then email us within 14 days of delivery with the photos and your order number. We replace damaged or missing parts free of charge, delivery included.

Can I send it back?

⌄
Yes. You have 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 and pay for: typically £150 to £250 from a UK mainland address. Faulty or damaged goods are a different case: tell us and we arrange and pay for everything.

Will we actually use it?

⌄
The honest risk with any sauna is the habit, not the build. Size for the people who will use it every week: a four-person room suits a family, or friends who come round. If you have never kept a sauna habit, try a month at a local gym first.

Who am I buying from?

⌄
Waldenhaus Limited, 71-75 Shelton Street, London WC2H 9JQ, Company No. 16877766. We sell garden structures for British weather: greenhouses first, and now saunas made to our specification.

What are my legal rights?

⌄
The Consumer Rights Act 2015 applies: goods must be as described, of satisfactory quality and fit for purpose. Distance orders carry a 14-day cancellation right under the Consumer Contracts Regulations 2013. These come from the law, whoever you buy from.
