Come here before you decide.
Buying is the easy part. A dozen sites will take five thousand pounds from you this afternoon. Knowing which sauna, or which plunge, suits your ground, your access and the way you will actually use it in February is the part nobody helps with. That is the part we do.
The hardest part is not spending £5,000. It is knowing you have spent it on the right one.
The mistakes are quiet. A cabin too big to heat cheaply. A plunge that cannot hold temperature through August. A base that shifts in the second winter until the door stops closing. None of them show in a photograph, and all of them last as long as the equipment does. So the useful thing a retailer can do is compare properly, say what each choice costs you, and name the one that belongs in a garden like yours. Often it is not the most expensive.
Two categories, no factory, no favourites.
Saunas and cold plunges. Nothing else, and no plans to widen it. Everything we learn goes into two categories rather than thirty.
No factory behind this and no house brand to defend, so we can tell you a product is wrong for you without arguing against ourselves.
We buy from manufacturers and sell to you. No commission, no referral fees, no payment for placement.
Next to the reasons to. On the sauna there are four, including the smoke control rule that stops some people owning one at all.
Three gates before anything is listed.
A short range is not a limitation. It is the promise being kept.
Construction, materials, performance, and which component fails first.
Against a British winter and a British garden. A published figure is a starting point, not a promise.
Warranty, parts, lead times and aftercare settled with the maker before anyone can order.
Five things we will not trade away.
They govern what we list, what we write and who we work with. Public, so you can hold us to them.
- If we cannot explain the price, we will not ask for it. Five thousand pounds needs a reason you can check. Where a figure is not published, we say so.
- If something cheaper suits you better, we will say so. A smaller model, a different maker, or waiting a year. We would rather lose the sale than win the complaint.
- Judged by British conditions. Rain, frost, and ground that is wet nine months of the year. Nordic figures are a starting point.
- Compromises are published, not buried. Every product page carries what the thing will not do, what it costs to run, and what its maker has not answered.
- We stay after the sale. One email to us and we deal with the manufacturer. That is what a retailer is for.
Two old words for cold water and high ground.
A tarn is a small mountain lake, the kind that sits in a hollow high up and stays cold all year. A fell is the high ground above it. Together they mean cold water beneath high ground, which is more or less the range.
Both words came into English from Old Norse and stayed in the north, which is why the Cumbrian map is full of them: Scafell Pike, Red Tarn under Helvellyn. The words are Norse and so is the tradition. Heat, then cold, then sit down and feel better than you did.
We are not in Cumbria and we are not going to pretend to be. The name describes something worth having in a garden, not a postcode.
Places like that slow people down. Not by invitation, but because cold water and high ground leave very little room for anything else, and nobody has ever stood in a tarn thinking about their inbox. That hour is the thing we are actually selling. The sauna and the plunge are only how it reaches a back garden, on a Tuesday, in February.
I wanted the retailer I could not find.
I spent a long time trying to buy this kind of equipment well. Plenty of people wanted to sell me something. Almost nobody would tell me which one suited the space I actually had, or that the honest answer was to wait.
So Tarnfell is built the way I wanted to be sold to. Compare properly. Say what a thing will not do. Put the running costs and the reasons not to buy where they are easy to find rather than easy to miss.
If you are weighing up a decision like this, write to me. You will get an answer from me rather than a queue.

Before you compare prices, compare products.
Two cabins at the same price can be built to different standards, and the difference rarely shows in a photograph. One is clad in thermally modified timber that silvers evenly and asks for nothing. Another is treated softwood that wants recoating every second year. One maker publishes measured consumption across a week; another quotes a peak wattage and leaves you the arithmetic. One warranty starts at delivery, another at the invoice date. On one tub the pump unbolts. On another it is integrated, and replacing it means replacing the unit. Price tells you almost none of that. A specification tells you some of it, if you know which figures predict how something performs and which are there to fill a table. The rest has to be asked for, in writing, before you order. Making those differences legible is the work.
Read the buying guidesWe do not ask whether it is good.
We ask whether you will still be glad you bought it in five years. It is a harder question, and it changes every question that comes before it.
Not how cold the water gets, but what the thing costs to keep once the novelty has worn off. Not whether there is a warranty, but whether its promises still mean anything on a wet morning in year four. Not how it is put together, but whether it can be looked after or only replaced. Not what it looks like new, but whether the people who made it are likely to still be there.
Most of that can be established before you buy, if somebody asks. Some of it cannot, and where we cannot answer honestly we are not ready to recommend anything. That is usually the reason something is absent from the range rather than in it.
