Something has happened to London and heat. Five years ago a proper sauna meant a leisure-centre box or a hotel spa day. In 2026 the city has aufguss amphitheatres, not-for-profit community saunas, Russian banyas, floating saunas and rooftop cabins — and the hardest part is choosing. This guide ranks the saunas we would actually send friends to, category by category, with honest notes on price, heat and atmosphere. We run a sauna house of our own in Shoreditch, so where we appear, we say so and let you judge. What separates a great sauna from a good one is consistent: heat quality, ritual, proper cold, and the people in the room.
Best for aufguss and social heat: The Sanctuary AndSoul, Shoreditch
Full disclosure: this is us. The Sanctuary &Soul is built around a 40-person amphitheatre aufguss sauna — London's second-largest — with towel-led aufguss rituals, 4°C cold plunges, sauna raves after dark, an alcohol-free bar and the Palm Greens café. It is heat as a social event rather than a solo endurance test, which is exactly what East London wanted. First visit is £29, memberships from £99 a month, and you can book a single session online. If you want silent, meditative heat, one of the venues below may suit you better; if you want ritual and a room with energy, start here.
Best low-cost sauna: Community Sauna Baths, Hackney Wick
The not-for-profit that arguably started London's sauna boom. Wood-fired barrel and cabin saunas, cold dunks in converted tubs, sessions from £9.50, and a genuinely mixed crowd. No frills, occasional queues, all charm. If price has kept you from sauna culture, start here.
Best authentic banya: Banya No.1, Hoxton
The real Russian article: dense steam, parenie birch-twig treatments and ice buckets, run by people who take it seriously. A parenie session is one of the great heat experiences in London. Expect to pay more per visit than anywhere else on this list, and expect it to be worth it once in a while.
Best floating sauna: Skuna, Canary Wharf
A wood-fired sauna on a boat in the dock, with a ladder straight into open water. Small, quirky and completely memorable.
Best budget authentic: Finnish Church, Rotherhithe
London's longest-running proper Finnish sauna, tucked inside the Finnish Church, from £12. Unchanged for decades, completely unpretentious, and the benchmark for what plain good heat feels like.
How to choose your sauna
Want ritual and a social room: The Sanctuary AndSoul. On a budget: Community Sauna Baths or the Finnish Church. Chasing an experience: Banya No.1, Skuna or a rooftop at sunset. Whatever you pick, go twice before judging: sauna rooms change completely with the crowd in them.
Sauna etiquette FAQ
How hot is a London sauna?
Most Finnish-style rooms run 80–95°C. Infrared cabins are gentler at 45–60°C. Aufguss rounds feel hotter than the thermometer suggests because moving air transfers more heat.
Do I need to shower first?
Yes, always — a soap shower before your first round. It keeps the room clean and actually helps you sweat. Every good sauna in this list expects it.
What is aufguss?
A guided ritual where a sauna master pours essential-oil-infused water onto the stones and moves the hot air with towel work, usually to music. It turns a sauna round into a 10–15 minute performance. The British Sauna Society keeps a calendar of aufguss events across the UK.
How long should a first-timer stay in?
Start with 8–10 minutes, cool down properly, rest, and repeat up to three rounds. Leave the room the moment you feel dizzy — there is no prize for staying longest. Drink water between rounds.
Sauna vs steam room — what is the difference?
Saunas are dry heat (10–20% humidity) at high temperature; steam rooms are 100% humidity at around 45°C. Dry heat suits contrast bathing with cold plunges; steam feels gentler on airways.
