Heater and stones are your choice

01Your heater

The heater is your choice. Take the cabin on its own for a heater you already have, or add a Harvia. Harvia rates the PC70 for rooms of 6 to 10 m³ and the PC90 for 8 to 14 m³. Counting the glass door as Harvia advises, this room comes to about 8.5 m³, so both fit, and the PC90 heats it faster. With the panoramic back wall, take the PC90. The PC90 needs a 40 A supply instead of 35 A. The dedicated supply and final connection by a competent electrician are not included.

02Choose your door

The black door comes with Black Edition. No need to add it twice.

Wood-fired: smoke control

Councils declare their own smoke control areas, street by street. Electric has no flue, so this check matters only if you are weighing up the wood-fired cabin.

4Delivery and build

How is the 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 cabin 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.

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 cabin: check the gate first.
99 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 joists go down level; measure both diagonals and make them equal.
No water connection, free drainage: no mains water is needed; the floor drain empties under the cabin.
Concrete slab, paving slabs or compacted gravel: whichever you choose, the cabin brings its own floor and base frame.

6Care and upkeep

How do you care for a timber outdoor sauna?

Four jobs matter: treat the outside before the first session and then at least every two years, and leave the inside untreated, keep the roof sealed, adjust the straps with the seasons, tighter in a dry summer and a little looser in autumn, 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 Cabin Four Two-Tier from the back: the shingle roof, the back wall with its round vent, three steel straps and the base joists
What keeps water out

83 shingles, sealed along the edges.

What you do

Seal it during the build, then check it yearly.

Bitumen shingles in rows along the roof edge1 / 2
Will rain get in?
Bitumen shingles, nailed on and sealed along the edges.

You nail and seal them during the build; the manual shows where the sealant goes. Look the edges over once a year.

Solid timber swells in damp weather and shrinks when it is dry. Adjust the steel straps with it, and treat the outside at least every two years.

Spring

Look over the shingles and the sealant along the edges. Clear leaves away from the base so that it drains.

Dry summer weeks

The boards shrink and the straps slacken: tighten the nuts on each strap evenly, until the strap sits snug.

Autumn

As the damp sets in, the boards swell: ease the strap nuts a little, so that the timber has room to move.

Winter

After each session, leave the door and the vent open until the room is dry. Brush heavy snow off the roof. If it stands unused, air it on a dry day every few weeks.

Every two years

Treat the outside again with an exterior wood preservative or stain. We do not supply it in the UK: any DIY shop sells it. The warranty asks for it, so keep a dated photo.

Inside

Never paint or varnish it. Sit on bench towels, and wash the benches, walls and floor at least every six months with a scrubbing brush and a sauna detergent, as Harvia advises.

The heater

Rearrange the stones at least once a year and replace any that have crumbled, as Harvia’s manual sets out.

Replacement parts

A board, a fitting or a panel: email us your order number and a photo, and we source the part.

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, seal, adjust, dry.

?FAQ

Questions about this sauna kit

Pick a subject, or type it.

Is four people realistic?

⌄
Yes, seated. Three on the upper bench along the back wall and one on the lower side bench, with the heater by the door. The upper bench is 205 cm long and 55 cm deep, the step below it 36 cm deep, the side bench 85 × 50 cm. 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 cabin covers 5.3 m² and stands about 2.4 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 cabin 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 cabin: solid timber walls, no added insulation; treat the outside before its first winter. Where it drops below 0 °C, Harvia does not recommend these heaters without background heating: below −5 °C the PC70 and PC90 cut-out can trip, and it resets only once the room is back above +18 °C; the electronic PC70E and PC90E, less sensitive to the cold, warm a cold room slowly.

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?

⌄
Not in the starting price: you can take the cabin on its own for a heater you already have. Add the Harvia Cilindro PC70, 6.8 kW, for £449, 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 cabin, so the base needs free drainage.

What exactly is it made of?

⌄
Solid timber boards for the 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 cabin 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 cabin. 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.
