Towel Between the Lines: London’s Late-Night Saunas Are the Anti-Club With a Locker Key

It is 12:47am on a Saturday in 2026 and you are not in a queue. You are not shouting over a DJ. You are not paying £14 for a drink that tastes like a vape. You are, instead, sitting in a steam room in east London, sweating gently next to a stranger who is humming something that might be Radiohead. This is the new after-dark scene, and it comes with a locker key.

Late-night saunas and banyas are having a moment in London. Not in a wellness-brochure way, more in a “I finished work at 11 and I want to be somewhere warm that isn’t my flat” way. The crowd is mixed: post-shift nurses, night-bus drivers, couples on a low-stakes date, people who have simply realised that a 1am plunge beats a 1am argument about where to go next. Here at 10nd0n we are not here to tell you to swap the club for a hot room. We are here to tell you it is already happening, and that you should probably pack two towels.

The anti-club dress code

The first thing to know is that a late sauna is not a spa day. There is no robe ceremony. There is no whale music, unless someone’s phone goes off and it is, unfortunately, a whale sound. You turn up, you pay, you get a wristband and a locker key, and you join the quietest night out in London. The dress code is towel, flip-flops and the expression of someone who has made a good decision for once.

Most places will give you a towel, but bring your own anyway. Bring a second towel if you plan to sit on it, because sitting bare on the wood is frowned upon in the same way as bringing a pint into a library. Bring water. Bring a pound coin for the locker if the venue is old-school, and bring a plastic bag for the wet stuff. The bag is the difference between a charming after-hours adventure and a bus ride home that smells like a swimming pool changing room.

Etiquette, or how not to become a steam-room legend for the wrong reason

Sauna etiquette is not complicated, but it is specific. Shower before you go in. Take your shoes off before the changing room. Sit on your towel. Do not stare, do not chat loudly, and do not treat the steam room like a group chat with benches. A nod is fine. A quiet word is fine. A full monologue about your podcast is not fine.

If you are in a banya, expect a bit more ritual. Some have birch whisks, cold plunges and a strict “no phones” policy that is enforced by a look from a regular who has been coming since before you knew what a banya was. If you are in a more general late-night sauna, expect a calmer, quieter version of the same. Either way, the golden rule is simple: read the room. If everyone is silent, be silent. If everyone is in the plunge pool, do not stand at the edge describing the temperature like a weather presenter.

Where the late slots actually are

Late licences in London are a patchwork, so the useful thing is not a definitive list of every venue but a way of finding the right one. Hackney and Bethnal Green have banyas and spa basements that run late, especially from Thursday to Saturday. Vauxhall has late-licence saunas with their own house rules and their own regulars. Further out, you will find a handful of places near big transport hubs that stay open for shift workers and people who simply refuse to go home at a sensible hour.

Best slots? Thursday and Friday from 10pm are the sweet spot: busy enough to feel alive, quiet enough that you can actually get a seat. Saturday after 11pm is peak, so book ahead or expect to wait. Sunday late is for the recovery crowd, which is a polite way of saying people who have had a weekend and would like their body to forgive them. Some venues advertise 24-hour opening, but check before you travel; a “late” sauna can mean 1am on paper and 11:45pm in practice.

The regulars you’ll meet between towels

Every late sauna has its cast. There is the post-shift nurse who arrives with a meal deal and the calm of someone who has seen everything. There is the banya dad who brings his own birch whisk and will explain it to you whether you ask or not. There is the couple who treat it as a date and sit in comfortable silence. There is the bloke who has clearly come straight from the gym and is treating the steam room as a cool-down. And there is the first-timer, clutching a towel like a passport, wondering whether they are allowed to leave their flip-flops outside.

You will also meet the people who have swapped the club for this for a reason. It is cheaper than a night out. It is warmer than a bus stop. It is social without being loud. And it ends with you smelling of eucalyptus instead of other people’s perfume. That is not a small thing in 2026, when the price of a good night out in London can make you reconsider your entire personality.

First-timer checklist (read before you steam)

Book ahead if you can. Take flip-flops, two towels, water and a plastic bag. Leave your phone in the locker. Shower before and after. Start with ten minutes in the steam, then cool down, then repeat. Do not drink alcohol before you go in. Do not try to prove anything. If you feel dizzy, get out and sit down. If you are unsure about the rules, ask at reception; they have answered every question before and they will not be shocked by yours.

And if you are going with a friend, agree a meeting point. The steam room is not the place to lose someone. The plunge pool is not the place to find them. The changing room bench, near the hairdryer that sounds like a small aircraft, is the place.

The post-steam glow

The strangest thing about a late sauna is how early it feels when you leave. You come out at 2am with wet hair and a calm that usually takes a holiday to achieve. The kebab shops are still open. The night buses are still running. The city is still doing its thing, but you are no longer in the middle of it. You are warm, slightly smug and carrying a bag of damp towels.

That is the pitch, really. Not a replacement for every night out, but a very good alternative for the nights when you want to be somewhere that is not your flat and not a dancefloor. London’s late-night saunas are the anti-club with better lighting, quieter conversation and a locker key. In 2026, that might be the most London night out there is.
