Buy once. Choose well.
Saunas and cold plunges, chosen for UK homes and gardens. We help you compare, understand and choose with confidence.
Heat, cold and a habit worth keeping.
The point was never another gadget. It is a habit you keep: a few minutes of heat or cold, most days, through a British year.
Tarnfell exists to help you choose the right sauna or cold plunge with confidence. We choose every product ourselves, explain what it will and won't do, and support you long after it's delivered.
No hype. No exaggerated claims. Just honest advice and equipment that has earned its place.
Four ways into the range.
From a two person indoor cabin that plugs into a socket to a six person barrel with a covered terrace, and a plunge bath that also plugs in. These four mark out the ground; the rest of the range sits between them.
Heat. Cold. Ideally both.
What buying from us is actually like.
Big purchases deserve straight answers. Here's the whole experience, before you spend a pound.
Ask us anything: sizing, running costs, what the neighbours will think. A person replies, honestly, within one working day.
Delivery and installation are quoted separately and shown on every product page before you order, never added at the checkout. Both depend on your postcode, your access and your site, so we confirm the real figures in writing rather than averaging them into the price. Lead times are stated up front, and the practical details of access, weight and siting are talked through before you order.
Warranties honoured properly, spares sourced, questions answered. The relationship starts at delivery; it doesn't end there.
Every one of them arrived the same way.
Through the same three gates. Nothing is listed until we have understood it properly, judged it against a British winter, and agreed warranty and parts terms in writing. There is real choice here; the filtering just happened before anything reached the page.

Five principles govern what we stock, what we write and who we partner with. Fail one and it does not get listed. They are public, so you can hold us to them.
- No inflatables. Ever. If it cannot live outside for a decade, it is not equipment, it is a toy.
- We don't chase trends. Cold water has worked for a thousand years. We stock the equipment, not the hype cycle.
- Judged by British conditions. Rain, frost, and a garden that is wet nine months a year. Scandinavian performance figures are a starting point, not a promise.
- Honest about what it won't do. The guides tell you when the cheaper option is the right one. No product here will fix your sleep, your mood and your marriage.
- One email to us. We handle the manufacturer. Warranty claims, spares and questions come to us, and we deal with the maker on your behalf. That is the whole point of buying from a retailer.
Read before you buy.
How is a garden sauna delivered?
A garden sauna arrives flat, as parts on one pallet, set down at the kerb. What it take...

Three gates, no commission, and the filtering that happens before anything reaches the ...
Access, ground, and the day the lorry arrives
Gate widths, turning space, soft ground and the pinch point three metres past the gate....
The hour before the day starts.
Three minutes of cold. Fifteen of heat. The kettle on before anyone else is up. Not a trend in the north, just what mornings are for.
