Arc (Canary Wharf)
Urban London, Greater London · cold dip: Brass Monkey ice baths kept between 1C and 5C · from £20
Arc opened in Canary Wharf on 31 January 2025 as the UK's first dedicated contrast-therapy club, built around a 65-person electric sauna that was the largest in the UK at opening, constructed by Finnmark and designed by Cake Architects. Heat runs to 88C, paired with a bank of custom Brass Monkey ice baths at 1 to 5C, and the offer is programmed sessions rather than drop-in, from Aufguss towel-waving and breathwork to Arc After Dark social evenings with DJs.
Blocfit
Urban London, Greater London · cold dip: check current cold-water options with the operator · from £10
Blocfit is a Brixton fitness space selling sauna-only passes from around £10, so you can use the heat without committing to a class or membership. It is a straightforward, affordable option for a quick sweat in south London, though it is a studio sauna rather than a dedicated wood-fired cabin.
Brockwell Lido
Lido & pool London, Greater London · cold dip: 50-metre unheated lido pool
Brockwell Lido is the pool most people picture when they imagine a London open-air swim: an Olympic-length unheated pool framed by a Grade II-listed 1937 Art Deco building in Brockwell Park. For sauna users it is one of the best-equipped lidos in the country, with a cylindrical outdoor sauna in the cooler months and a mixed indoor sauna and jacuzzi open year-round, and the 50-metre cold pool makes an unmatched plunge. Operations moved to Active Lambeth in 2026 after the previous operator entered administration.
DRIP Saunas
Riverside London, Greater London · cold dip: Thames-side setting
DRIP Saunas runs a pop-up, mobile-format sauna on the Coaling Jetty opposite Battersea Power Station's north entrance. It operates a limited season, so check the operator's site for current availability before travelling.
Parliament Hill Lido
Lido & pool London, Greater London · cold dip: 61-metre unheated pool
Parliament Hill Lido's stainless-steel 61-metre pool on the edge of Hampstead Heath is a favourite of cold-water regulars, and its sauna runs through the winter season only, closing for summer. Sessions are sold by the hour to adults only, with 30 tickets per session on a first-come, first-served basis, so arrive early on cold mornings. It is run by the City of London Corporation.
Sauna Social Club
Urban London, Greater London · cold dip: cold plunge · from £24.99
Sauna Social Club leans into the sociable side of the practice in Peckham, one of south London's densest sauna neighbourhoods. Its Social Sauna session runs close to two hours for about £24.99, turning a quick sweat into a proper unwind, and it contrasts nicely with the cheaper Community Sauna Baths site in the same area.
Sea Lanes Canary Wharf
Lido & pool London, Greater London · cold dip: the open-air lido pool itself
Sea Lanes Canary Wharf is a six-lane, 50-metre freshwater pool that floats on Eden Dock rather than drawing from the Thames, with two glass-fronted saunas overlooking the water and the whole site powered by renewable energy. Due to open in summer 2026, it comes from the National Open Water Coaching Association team behind Sea Lanes Brighton, and its cold-water side is real outdoor open water rather than a curated ice bath.
Slomo (King's Cross)
Urban London, Greater London · cold dip: three cold plunge pools plus a dedicated ice tank · from £12
Slomo brings serious contrast therapy to central London with two wood-fired saunas, three cold plunge pools and a dedicated ice tank near King's Cross. Sessions from around £12 for 50 minutes are remarkable value for zone 1, making it the easiest after-work option for anyone near King's Cross or St Pancras.
The Cabin
Urban London, Greater London · cold dip: three plunge pools · from £7
The Cabin on the edge of Clapham Common runs two wood-fired saunas and three plunge pools at around £7 an hour, which makes it among the cheapest proper saunas anywhere in London. The common-side location suits a sweat after a run or cold dip, and the low price makes a weekly routine realistic.
The Finnish Church Sauna
Urban London, Greater London · cold dip: cold showers · from £12
The sauna inside the Finnish Church in Rotherhithe is the most authentic Finnish sauna in London, maintained for decades by the city's Finnish community and used by Finns as much as curious Londoners. Ninety-minute sessions cost around £12 with private hire from about £25, and the atmosphere is calmer and more traditional than the newer venues, with cold showers rather than a plunge pool.
Wild Riverside Sauna
Riverside London, Greater London · cold dip: riverside setting
Wild Riverside Sauna is a seasonal pop-up at Barking Riverside in east London, listed on the British Sauna Society events calendar. Like most Thames pop-ups it moves and pauses between seasons, so verify current status before planning a visit.
TEMZ Floating Saunas
Riverside Teddington, Greater London · cold dip: ice baths · from £20
TEMZ Floating Saunas is described as London's first floating sauna, a Scandinavian-style cabin operating on the Thames at The Lensbury in Teddington with sauna-and-ice-bath sessions and private hire. It offers the genuine on-the-water experience the land-based east London venues cannot, and sessions start from around £20.
