UK sauna boom turns ice baths into a social ritual

The Bath House in Belgravia captures the UK’s sauna boom in one vivid scene: step into a historic bank building, pass through a carefully built Russian banya, and finish in an icy plunge pool. What once looked like an odd wellness import now feels like a social format with its own codes, its own price points, and its own crowd.

Inside the ritual

The Bath House opened in December 2019, and the detail shows. City A.M. described the design as a serious piece of craft, from the authentic tiles and extravagantly detailed oven in the main sauna to the murals that give the room a Central European countryside feel. The venue describes itself as an oak-lined banya with an icy plunge pool, plus rituals, scrubs, massage, aromatic leaves, and home-cooked food and drink.

That mix matters because the cold plunge is no longer standing alone as a recovery tool. Here, it sits inside a larger experience: heat, scent, steam, food, and a tightly choreographed shift from one temperature to the next. Belgravia Village places the venue in a historic bank building directly across from Buckingham Palace, which only sharpens the contrast between the old-money setting outside and the earthy bathing ritual inside.

Why the cold dip is suddenly the draw

The bigger story is not just that more people are trying ice baths. It is that the hot-and-cold circuit has become the product. The UK’s Finnish-style public sauna count has grown from around 45 in 2023 to more than 700 today, with 100 opening in 2026 alone, a leap that shows how quickly a niche has turned into infrastructure.

That expansion has been pushed by the wellness sector, the post-Covid appetite for experiences, the well-publicized benefits of moving from hot to cold, and the simple appeal of spaces that can replace a pub visit without asking people to drink. In that market, The Bath House is a useful marker: it is not a pop-up novelty, but a permanent venue selling a recognizable ritual.

From athlete recovery to social life

Contrast therapy has moved well beyond the sports crowd. The Standard’s 2026 guide traces the practice back to Ancient Rome, with its frigidarium and tepidarium, and points to sauna cultures that remain deeply embedded in Scandinavia, eastern Europe, and Japan, where hot springs called onsens are part of everyday life. The current UK boom borrows that heritage but packages it for modern social use.

That shift is visible in the language around these venues. The Standard has described saunas as “the new pub,” and the phrase fits the way people are using them: for mood, ritual, conversation, and time together. At sites like Community Sauna in Walthamstow, the draw is not just a single hot room but a neighborhood scene with multiple saunas, plunge pools at varying temperatures, and events that range from aromatherapy to group sing-alongs.

How London built the scene

London’s sauna movement has been building for years. Community Sauna Baths opened its first east London site at the beginning of 2022 on a derelict site behind a 1930s public bathhouse, and by January 2024 its Hackney Wick site had already attracted more than 50,000 visitors since launch day. That same site had 10 saunas of varying sizes, including converted horse boxes and traditional Finnish styles, showing how broad the format had already become.

Pricing helped widen the audience. Stratford Community Sauna Baths offered off-peak entry at £8.50 and peak entry at £15, while also being free for NHS workers and available through NHS trusts in Hackney and Newham. Community Sauna Baths says on its website that it also offers free community sessions, free sessions for NHS social prescribing referrals, concession memberships, and events for underrepresented groups.

The events calendar tells you just as much as the price list. By April 2025, Community Sauna Baths’ programming included storytelling, sound baths, queer poetry, aromatherapy, breathwork, life-drawing, and singing. It is not hard to see why this format has caught on: people are not only paying to sweat, but to belong.

A market big enough for permanent destinations

The commercial end of the scene has grown alongside the community model. In January 2025, The Standard described ARC in Canary Wharf as the UK’s first communal contrast-therapy site, and in March 2025 Dezeen reported that its amphitheatre-style sauna fits 65 people, making it the largest sauna in the UK. That scale matters because it shows the market has moved past one-off bathing curiosities and into purpose-built venues that can handle volume.

The British Sauna Society has helped give the movement a cultural spine. Founded in 2014 by London-based expatriate Finn Mika Meskanen, it says its aim is to “put Britain back on the map of great bathing cultures.” That ambition now feels visible across London, from Walthamstow and Hackney Wick to Canary Wharf and Belgravia.

What The Bath House tells ice-bath readers

For anyone who follows ice baths, The Bath House shows where the scene is heading. The value is not just the plunge itself, but the complete hot-cold ritual, the setting, and the sense that you are doing something social without turning it into a night of drinks. That is why older spa formats can feel flat now: they offer treatment, while these new venues offer a routine with mood, movement, and company built in.

The Bath House works because it makes the ritual feel grounded and repeatable. In a city where sauna culture has exploded from a few dozen sites to hundreds, the Belgravia banya shows why the cold dip is no longer the finale. It is the hook that brings people through the door, and the reason they come back.
