Delivery & installation
Delivery is available across the UK and the charge is confirmed for your postcode in writing before anything is dispatched. Offshore and some remote postcodes cost more, and we tell you the figure before you commit rather than after.
The cabin arrives flat, as wall, roof and glass panels with the bench, heater and kit boxed separately, 120kg in total on the maker's figure. The number of packages and the size of the largest one are being confirmed with the distributor and are not published here until they are, because on an indoor cabin the question that matters is whether the largest panel turns your stairs.
Installation can be arranged where you would rather not build it yourself. Once you place your order we confirm the delivery and installation options for your address, and nothing is dispatched until you are happy with both.
Warranty
Seven years on the wood structure and two years on the electrical components, which are the terms France Sauna publish for the Zen range in its specification sheet.
The UK administration of that warranty runs through the distributor, and we are confirming the claims process in writing before this sauna becomes buyable. Until then the figures above are the maker's published terms rather than a promise we have tested.
Claims come to us. One email, and we deal with the distributor and the maker on your behalf rather than handing you a phone number.
Returns
Until the order is placed with the supplier you can cancel and be refunded in full, with no reason needed.
After that the cabin is on its way from the distributor, and our returns policy sets out exactly where that leaves you. Check the packages against the parts list on the day they arrive and tell us about anything damaged or missing within 48 hours; anything that arrives damaged or faulty is ours to put right either way.
About this product
The Zen 2 is a 1,200mm by 1,100mm cabin, 1,900mm tall, built in Canadian spruce with an 8mm toughened glass door and a matching glass panel beside it. One bench with a headrest on the wall, seating two. Soft lighting sits in the top corner and under the bench.
It is a traditional electric sauna rather than an infrared one: a 3.5kW Harvia Vega heater with its stones is in the price, along with the wooden bucket and ladle, the thermometer and hygrometer and the sand timer. Water on the stones gives the burst of steam a Finnish sauna is known for.
The heater needs its own circuit, fitted by an electrician. Harvia rate the 3.5kW Vega at 16A on a 230V single phase supply in 2.5mm² cable. Everything else about it is fixed, so there is nothing to configure.
Who this is actually for.
Every product here is described with the honest opposite beside it: who it suits, and who should be looking at something else. If none of the descriptions below fits you, the right answer is elsewhere in the range, or elsewhere entirely, and we would rather say so.
Stones, steam and a ladle, in 1.2 by 1.1 metres. The 3.5kW Harvia heater draws about 15 amps at 230 volts, so it needs a 16 amp circuit of its own, which is an afternoon for an electrician rather than a conversation with the network operator. A spare bedroom, a large bathroom or a utility room will take it.
Worth confirmingyou want more than two people in it, or room to lie down. One bench, two seats, and the bench is 1.2 metres long. The Zen 3 and Zen 4 in the same range seat more, and we would rather point you at one of them.
Most cabins at this size are sold bare and the heater is added at the checkout. Here the Harvia Vega, its stones, the bucket, the ladle, the thermometer and the sand timer are all in the £1,802, so the figure on this page is the figure you pay for a working sauna, before delivery and the electrician.
Worth confirmingyou want WiFi, a schedule or an app. The Vega is controlled by two switches on the heater itself, a timer and a thermostat, and that is all. It is simple, which is a virtue, but it will not warm up while you drive home.
The product that gets used is the one worth recommending, and it is not always the largest one.
The measurements that decide it.
Read this before anything else. An indoor cabin is almost never sent back because it was the wrong product; it is sent back because it would not go up the stairs or stand up in the room.
The ceiling is the one to respect. The finished cabin is 1.9 metres tall, but the wall panels are tipped upright during assembly and there has to be room above them to do it. Measure where the cabin will actually stand, not at the door.
From order to first use.
Here is each stage, and who does what. Before you order, email hello@tarnfell.com and we will confirm the current lead time and the delivery cost for your postcode in writing.
- Week 0
Order and room check
Ceiling height, floor, access and your consumer unit are agreed before the order is placed with the distributor. There is nothing to configure on the cabin itself.
- Before it arrives
The circuit
An electrician runs a 16A single phase circuit to the corner where the heater will hang and leaves it ready to terminate. A room containing a sauna heater is notifiable work, so this is not a job for a competent friend.
- Delivery day
To the door, in panels
The cabin arrives flat as wall, roof and glass panels with the bench, heater and kit boxed. Check everything against the parts list the day it lands, which is the easy time to find out.
- Build day
Two people, working from the manual
Wall panels up, glass in, roof on, bench and heater guard fitted. If you would rather hand it over, installation is arranged for your address once you have ordered.
- Before first use
The electrician returns
The heater is hung, connected and the circuit tested and certified. You should be handed a certificate. Then the stones go in, loosely, and the first heat cycle burns off the factory smell with the door open.
What owning one actually involves.
The handful of things that decide whether this is still in use in year three.
The Harvia Vega is controlled by a timer and a thermostat on the heater itself. Set both, wait for the stones to come up, and throw water when you want steam. There is no app and nothing to pair, which is either the point or the problem, depending on who you are.
Spruce carries pitch pockets that cannot be seen when the boards are sorted. If one is near the surface, heat softens it and it weeps. Acetone on a rag takes it off, or let it harden and scrape it. Worth knowing before it happens rather than after.
An unheated timber room in a house that breathes is where mould starts, and one cycle a month prevents it. This is Harvia's standing advice for any cabin left idle.
Nothing else inside. Bare timber in a sauna is meant to stay bare, and detergents leave a film that bakes.
The running costs, with the working shown.
The purchase price is public; the running cost rarely is. Ours are published with the assumptions stated, so you can check the arithmetic and change it for your own tariff.
about 90p
Heat up: 3.5kW for 35 minutes is 2.0 kWh, because 2.5 cubic metres does not take long. Holding: 1 hour at roughly 40% duty is 1.4 kWh. Total 3.4 kWh at 26.11p is about 90p.
about £94
104 sessions at 90p. For comparison, the same arithmetic on an 8kW outdoor barrel comes to about £380, and that is before the weather gets involved.
a few pounds, every few years
Sauna stones crack and crumble with use and are restacked yearly and replaced when they do. Harvia's 3.5kW Vega takes 12kg. They are the only consumable part.
Assumptions: electricity at the Ofgem price cap unit rate of 26.11p per kWh, 1 July to 30 September 2026, including VAT. Figures are calculated from the heater's rated output of 3.5kW, not measured on an installed cabin. Neither France Sauna nor Harvia publish a heat up time for this cabin; 35 minutes is our working figure for a room of about 2.5 cubic metres indoors, and it says so here rather than being presented as theirs. An indoor cabin in a heated house loses far less than an outdoor one, so these sums are closer to the truth than the same sums on a garden sauna.
What you have to do, and what the rules require.
Everything you have to do, and how often.
| Job | How often | Who |
|---|---|---|
| Install and certify the circuit 3.5kW draws about 15A at 230V. Harvia publish the 3.5kW Vega as 230V single phase on a 16A fuse with 3 x 2.5mm2 cable, or 400V two phase at 2 x 10A with 4 x 1.5mm2. A room containing a sauna heater is notifiable electrical work in England and Wales. | Once, before first use | A qualified electrician |
| Restack and inspect the stones Lift them out, discard any that are cracked or crumbling, and restack loosely so air moves between them. Tightly packed or broken stones make the elements work harder. | Yearly | You |
| Heat it even when you are not using it One heating cycle a month if the cabin is out of use for a while, to keep mould from forming in the timber. | Monthly when idle | You |
| Air it after use Leave the door open until the room is dry. Trapped damp is what marks benches, not heat. | Every session | You |
| Wipe the bench down A damp cloth and warm water only. Nothing film forming. | Monthly, or after heavy use | You |
| Deal with resin if it appears Pitch pockets occur in spruce and cannot be seen during sorting. Leaking pitch comes off with acetone on a rag, or leave droplets to harden and scrape them carefully. | As it happens | You |

Reasons to buy something else.
One bench, 1.2 metres long, two seats. The Zen 3 and Zen 4 in the same range are the answer for a family, and we would rather sell you one of those than watch three people share this.
The heater will not run from a socket. If a dedicated circuit is not possible where the cabin would stand, an infrared cabin on an ordinary supply is the honest alternative, and the Moon 2 is one.
Two switches on the heater, a timer and a thermostat, and nothing beyond them. It is simple by design. If you want the sauna warm when you walk in from the car, this is not the cabin that does it.
A timber cabin wants a dry room with air moving through it. A sauna does not fix a cellar; it makes the problem worse and puts spruce in the middle of it.
If any of these apply, say so and we will point you at what does suit you, including when that is a cheaper product or one we do not sell.
What we know, and how we know it.
Not a rating. A record of where every figure on this page comes from: what we have checked against a published document, what a maker states and we have not yet checked, and what is still open.
- Dimensions, construction, weight and contents
-
Verified
Size, timber, glass, weight, the bench and headrest, the lighting and the contents of the kit are taken from France Sauna's own specification sheet for the Zen range, March 2023 edition, and match the UK distributor's listing.
- Heater and electrical supply
-
Verified
Output, fuse rating, cable size, stone quantity and room rating are Harvia's published data for the 3.5kW Vega, the only 3.5kW heater in the Vega range. The 15A current is our own arithmetic from the rated output.
- Heater height rating
-
Information not yet published
Harvia's data for the 3.5kW Vega lists a minimum room height of 2 metres. The Zen 2 stands 1.9 metres tall outside. The maker supplies the two together, and we are asking the distributor to confirm the pairing in writing before this page becomes buyable rather than assume it.
- Packages and lead time
-
Information not yet published
The maker publishes a total weight but not the package count or the size of the largest panel. Both, and the lead time from the distributor, are being confirmed.
- Warranty administration
-
Information not yet published
Seven years on the wood and two on the electronics are the maker's published terms. How a claim is handled in the United Kingdom is being confirmed with the distributor before this sauna becomes buyable.
These states move as the evidence does. When a figure is measured on an installed cabin, by us or by an owner who will let us, it moves from stated to verified and this section says so.
