Cold plunges and saunas

Buy once. Choose well.

Saunas and cold plunges, chosen for UK homes and gardens. We help you compare, understand and choose with confidence.

Why Tarnfell exists

Cold water, warm timber and time outdoors.

The point was never another gadget. It is a habit you keep: a few minutes of heat or cold, outdoors, 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, a short range and equipment built to last.

Our promise

What buying from us is actually like.

Big purchases deserve straight answers. Here's the whole experience, before you spend a pound.

01 · BEFORE YOU BUY Real answers, no pressure

Ask us anything: sizing, running costs, what the neighbours will think. A person replies, honestly, within one working day.

02 · DELIVERY DAY Clear from the start

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.

03 · THE YEARS AFTER We stay reachable

Warranties honoured properly, spares sourced, questions answered. The relationship starts at delivery; it doesn't end there.

The opening range

Our range is short on purpose.

Nothing is listed until we understand it properly, have judged it against a British winter, and can stand behind it with warranty and parts for years. That takes longer than filling a catalogue.

The Tarnfell Principles

Cheap kit gets abandoned by February.

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.

  1. No inflatables. Ever. If it cannot live outside for a decade, it is not equipment, it is a toy.
  2. We don't chase trends. Cold water has worked for a thousand years. We stock the equipment, not the hype cycle.
  3. 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.
  4. 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.
  5. 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.
The hour before the day starts.
Cold, then heat

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.
