Delivery & installation
Delivery is included in the price, kerbside to mainland Britain: England, Wales and mainland Scotland. The Scottish Highlands, islands and any address a lorry cannot reach are quoted in writing before dispatch, and if the figure does not suit you, cancel for a full refund. Northern Ireland: write to us before ordering. Nothing is added at checkout.
The cabin arrives flat, as wall panels, roof and glass door, with the benches, heater and kit boxed separately. On an indoor cabin the question that matters is whether the largest panel turns your stairs, and we confirm that with the distributor for your address before anything is dispatched.
If you would rather not build it yourself, we can introduce you to an independent installer near you, typically from £650, paid to them directly. Once you place your order we confirm your delivery date, and if you want an installer we introduce you to an independent one near you.
Warranty
Ten years on the wood and two years on the electronics, which are the terms Holl's publish for the Hybrid Combi in its specification sheet.
The UK distributor administers the warranty and raises claims with the maker where needed. The cabin is sold for home use: commercial or very frequent use can affect cover.
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 Combi 2 is a two person indoor cabin that does both kinds of sauna. Four quartz and magnesium infrared emitters and a 100W carbon panel, 2,200W in all, warm you directly at up to 60°C. A Harvia Vega 3.5kW heater with 12kg of stones takes the room hotter and gives you steam when you throw water.
It is 1,400mm wide, 1,300mm deep and 1,900mm tall, in spruce with a red cedar finish, with a safety glass door, a bench with abachi headrests and a digital control panel with FM, MP3 and Bluetooth audio. Interior lighting and seven colour LED chromotherapy are included.
Both heating systems are in the price. Harvia specify a 16 amp fuse for the 3.5kW heater on single phase. The cabin is hard wired on its own circuit by an electrician, and Holl’s give ten years on the wood and two on the electronics.

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.
Infrared warms you directly at 40 to 60°C and is the easier session to sit in for longer. A traditional sauna heats the room to 80°C or more and gives you steam when water hits the stones. The Combi 2 has four quartz and magnesium emitters and a carbon panel for the first, and a 3.5kW Harvia heater with stones for the second, in a cabin 1.4 metres wide.
Worth confirmingyou already know which you want. A single system cabin of the same size costs less: the Apollon range is infrared only from £1,907, and the Zen 2 is a traditional two seater at £1,802.
At 1.4 by 1.3 metres the Combi 2 fits where a four seat cabin will not. Harvia specify a 16 amp fuse for the 3.5kW Vega on single phase, and the infrared side is rated at 2,200 watts. Both are in the £3,799, with the audio and the lighting.
Worth confirmingyou need it to run from a plug. It is hard wired on its own circuit, like every cabin with a traditional heater.
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 supply is the one to check. Harvia specify a 16 amp fuse and 3 × 2.5mm² cable for the 3.5kW Vega on single phase, and the infrared side draws up to 2,200 watts.
From order to first use.
Here is each stage, and who does what. Delivery is estimated at 10 to 14 working days from order. If you would rather have stock, the date or anything else settled first, email hello@tarnfell.com before you order and we will confirm it 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 dedicated circuit to the cabin and leaves it ready to terminate. A room containing a sauna heater is notifiable work.
- Delivery day
To the door, in panels
The cabin arrives flat as wall panels, roof and glass door, with the benches, emitters, heater and kit boxed. Check everything against the parts list the day it lands.
- Build day
Two people, working from the manual
Panels up, door in, roof on, bench, emitters, heater and control panel fitted. If you would rather hand it over, we introduce you to an independent installer near you 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.
Infrared sessions run at 40 to 60°C and are ready sooner. The Harvia heater takes the room hotter and gives you löyly when you throw water. Most owners of a hybrid use the infrared on weeknights and the stones at the weekend.
Temperature, timer, lighting and audio are set on the panel, with FM radio, MP3 and Bluetooth.
Throw water on the heater stones only. The infrared emitters are electrical panels and are not made to be splashed.
Oils and varnishes bake and smell at sauna temperatures. Warm water and a damp cloth are all the benches need.
An unheated timber room is where mould starts, and one cycle a month prevents it.
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 53p
15 minutes warm up and 40 minutes in use at the full 2,200W is about 2.0 kWh, or 53p at 26.32p. In practice the emitters cycle, so this is a ceiling.
about £1.05
Heat up: 3.5kW for 45 minutes is 2.6 kWh. Holding: 1 hour at roughly 40% duty is 1.4 kWh. Total 4.0 kWh is about £1.05.
about £55 to £109
104 sessions, infrared only at the low end and traditional only at the high end. Most owners will land between.
Assumptions: electricity at the Ofgem price cap unit rate of 26.32p per kWh, 1 October to 31 December 2026, with no VAT on household electricity in that period. Figures are calculated from the rated outputs, 2,200W infrared and 3.5kW for the heater, not measured on an installed cabin. Warm up times and the 40% holding duty are our working figures, not the maker's.
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 The 3.5kW Vega draws about 15A at 230V and Harvia specify a 16A fuse with 3 × 2.5mm² cable on single phase. The infrared side is rated at 2,200W, about 9.6A. Holl's do not state whether both run together, so the circuit is sized for both. 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, and restack loosely. | Yearly | You |
| Wipe the emitter faces A dry cloth with the cabin off and cool. No water on the emitters. | Monthly | You |
| Heat it even when you are not using it One cycle a month if the cabin is out of use. | Monthly when idle | You |
| Air it after use Leave the door open until the room is dry. | Every session | You |

Reasons to buy something else.
A single system cabin costs less. The Apollon range is infrared only from £1,907, and the Zen 2 is a traditional two seater at £1,802.
At 1.9 metres tall outside, this is a sit down cabin.
The bench seats two. For four, look at the Utopia 4 or the Canopée 3C.
A timber cabin wants a dry room with air moving through 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.
