Scotland and cold water have a long history. The Loony Dook — the mass New Year's Day sea swim in South Queensferry, at the foot of the Forth Rail Bridge — has taken place annually since 1987 and now attracts thousands. Wild swimming communities are active year-round across Scottish lochs, rivers, and coastlines. The Portobello Beach swimmers, the Broughty Ferry regulars, the morning dippers at countless Highland lochs — Scots have always embraced cold water, often in conditions that would send most other nationalities indoors.
The sauna was the inevitable next step. And in 2026, Edinburgh and Glasgow both have sauna scenes that are genuinely worth making a trip for.
Edinburgh
Portobello Beach Sauna
If you want to understand why saunas and Scotland belong together, Portobello Beach Sauna is the argument. Portobello is Edinburgh's beach — a proper sand beach five kilometres from the city centre, facing the Firth of Forth, with the famous Portobello open-air pool nearby and a year-round wild swimming community that treats the Forth's waters as a perfectly reasonable place to be at any time of year.
The beach sauna here makes the combination complete. You warm up properly, then you walk across the sand and into the Firth. The water is cold — the North Sea cold, not Atlantic cold, but cold enough — and the contrast is exactly as good as it sounds. This is Edinburgh's most honest sauna experience: unpretentious, genuinely effective, and connected to the landscape in a way that hotel spa saunas never are.
It's also the most straightforwardly Scottish sauna experience available. Portobello is Edinburgh without the festival crowds, and the beach sauna fits perfectly into the neighbourhood's personality.
One Spa Edinburgh
At the opposite end of the spectrum, One Spa Edinburgh — in the Sheraton Grand Hotel — is one of Scotland's most celebrated luxury spa experiences. The facilities are extensive: thermal pool, vitality pool, hydrotherapy suite, and a sauna and steam room complex that is properly maintained and properly hot.
One Spa is Edinburgh's most glamorous sauna option. If you're visiting for a special occasion — a birthday, an anniversary, or simply a treat-yourself trip — this is the obvious choice. The hotel's spa package options mean you can spend an entire afternoon here without it feeling indulgent.
Balmoral Spa
Balmoral Spa at The Balmoral Hotel is Edinburgh luxury at its most iconic. The Balmoral's clock tower is one of Edinburgh's defining landmarks — the hotel deliberately runs its clock three minutes fast so guests don't miss their train from the adjacent Waverley station, a small piece of Edinburgh eccentricity that tells you everything about the place. The spa is appropriately grand: beautifully maintained, impeccably staffed, and situated in a hotel where the standards in every department are exceptionally high.
This is not a budget option, but the experience of using a spa within one of Britain's great Victorian railway hotels — all dressed stone, deep carpets, and the weight of history — is genuinely special.
Thermae Scotland
Thermae Scotland takes a different approach — the name intentionally echoes Thermae Bath Spa in Bath, and the ambition is similarly focused on thermal water and comprehensive contrast therapy. As Edinburgh's dedicated contrast therapy venue, Thermae Scotland offers a full programme of sauna, cold plunge and rest cycles in a purpose-built environment.
For those who want the full sauna and cold plunge experience in Edinburgh — rather than a luxury spa treatment with a sauna room attached — Thermae Scotland is the destination.
Glasgow
Blythswood Square Spa
Glasgow's finest hotel spa is at Blythswood Square — a five-star hotel in a converted Georgian townhouse in the heart of the city. The spa is celebrated for its pool and thermal facilities, and the sauna and steam rooms here are among the best in the city.
Blythswood Square has the kind of atmosphere that makes you feel like you're in a proper European spa hotel — the combination of grand architecture, attentive service, and excellent facilities creates an experience that genuinely rivals the best spa hotels on the continent. Glasgow visitors who want luxury in a Scottish context should look no further.
Bòthan Sauna Glasgow
Bòthan Sauna Glasgow is the community-focused alternative — bòthan is a Gaelic word for a small hut or bothie, and the name captures the ethos. This is not a luxury spa. It is an honest, well-run sauna experience built for the Glasgow community, with prices and accessibility that reflect that.
Bòthan has built a loyal following in Glasgow for exactly the same reasons that community saunas have taken off in London: people want access to genuine sauna culture without the spa price tag, without the towelling robes and cucumber water, without the feeling that you're paying for aesthetics as much as experience. The Gaelic name also signals something about the venue's values — connection to a Scottish and Celtic tradition of communal gathering around warmth.
The Baths Glasgow
The Baths Glasgow is a historic venue — a Victorian-era public baths building that has been repurposed and renovated to bring contemporary wellness facilities to a building that has served Glasgow's citizens for well over a century. There is something profoundly satisfying about experiencing a sauna in a space that was built specifically for public bathing, even if the facilities have been modernised significantly.
Glasgow has a rich tradition of public baths — the Victorian city was progressive in understanding that access to bathing facilities was a public health matter, not a luxury — and The Baths Glasgow continues that tradition in a contemporary form.
Day Trips from Edinburgh and Glasgow
Both cities are well-positioned for sauna day trips into the wider Scottish landscape. From Edinburgh, the Fife coast offers coastal wild swimming and several outdoor wellness venues. From Glasgow, Loch Lomond is an hour by car — and Loch Lomond's cold, clear water offers one of Scotland's most spectacular cold plunge experiences, particularly combined with any nearby sauna.
The broader Scotland sauna scene — covering Aberdeen, Inverness, Dundee, and beyond — is expanding rapidly. Check thermae.app for venues across Scotland.
