A lido sauna gives you the full Nordic cycle in one place: swim a length of cold open-air water, then warm through in a sauna a few steps away. A lido (a public outdoor swimming pool, usually Art Deco-era in Britain) is the natural home for contrast therapy (alternating hot sauna heat with a cold plunge or cold-pool dip), and a wave of UK pools added saunas through 2025 and into 2026.

LONDON · HERNE HILL

Brockwell Lido Editor's pick

Iconic 1937 Art Deco lido with both an outdoor and an indoor sauna

  • Year-round saunas
  • Architecture lovers
  • Serious cold swims
4.5 / 5
  • Pool 50m unheated
  • Sauna Outdoor + indoor
  • Outdoor sauna Cooler months
  • Listed Grade II Art Deco
Brockwell is the lido 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: a cylindrical outdoor sauna runs in the cooler months, and there is a mixed indoor sauna and jacuzzi open year-round. Operations moved to Active Lambeth in 2026 after the previous operator entered administration, but the lido's future is now secured.

What we liked

  • Both an outdoor and a year-round indoor sauna
  • Genuine 50m cold-water pool for contrast swims
  • Easy to reach in south London

Watch out for

  • Very busy on warm weekends
  • Outdoor sauna is seasonal, not year-round

The closest thing London has to a one-stop Nordic cycle: swim cold, warm up, repeat - all within the same Art Deco walls.

LONDON · HAMPSTEAD HEATH

Parliament Hill Lido

A 61-metre Heath-side pool with a winter-only sauna

  • Winter swimmers
  • Long-pool training
  • Heath walkers
4.0 / 5
  • Pool 61m unheated
  • Sauna Winter season
  • Tickets 30 per session
  • Age 18+ only
On the edge of Hampstead Heath, Parliament Hill's stainless-steel 61-metre pool is a favourite of cold-water regulars. The sauna runs through the winter season and closes for summer, so it is the opposite of a year-round venue. Sessions are sold by the hour to adults only, with 30 tickets per session on a first-come, first-served basis - arrive early on cold mornings.

What we liked

  • Long pool ideal for cold-water lengths
  • Right on Hampstead Heath
  • Run by the City of London Corporation

Watch out for

  • Sauna is winter-only
  • Limited tickets sell out fast
  • Adults 18+ only for the sauna

LONDON · CANARY WHARF

Sea Lanes Canary Wharf Opening 2026

A new floating 50m lido with two renewable-powered saunas

  • Early adopters
  • City-centre swims
  • Sauna-with-a-view
4.5 / 5
  • Pool 50m, 6 lanes
  • Saunas Two, glass-fronted
  • Opens Summer 2026
  • Power Renewable
Due to open in summer 2026 at Eden Dock, Sea Lanes Canary Wharf is a six-lane, 50-metre freshwater pool that floats on the dock rather than drawing from the Thames, with two glass-fronted saunas overlooking the water and powered entirely by renewable energy. The water is naturally filtered to EU Bathing Standards, and the site adds a clubhouse, wellness events and a wetsuit concierge. It comes from the National Open Water Coaching Association, the team behind Sea Lanes Brighton.

What we liked

  • Two dedicated saunas with dock views
  • Brand-new, purpose-built wellness facilities
  • Central, step-free access

Watch out for

  • Not open until summer 2026
  • Opening date subject to schedule

A purpose-built lido where the saunas are part of the plan, not a later add-on.

EAST SUSSEX · SALTDEAN

Saltdean Lido Editor's pick

Heated coastal pool with a sauna and cold plunge

  • Contrast-therapy fans
  • Walk-in sessions
  • Seaside swims
4.5 / 5
  • Pool 40m heated
  • Sauna Wed–Sun
  • Cold plunge Yes
  • Booking Walk-ins ok
Just east of Brighton, Saltdean pairs a restored 40-metre heated outdoor pool with a dedicated sauna and cold-water plunge run by The Wandering Wild Spa. Sessions run Wednesday to Sunday, with shorter 30-minute slots first thing and longer 55-minute sessions later in the day, and walk-ins are welcome. The on-site cold plunge means you get a proper hot-cold cycle without relying on the main pool being open.

What we liked

  • Sauna and a dedicated cold plunge on site
  • Walk-ins accepted alongside bookings
  • Heated pool extends the swimming season

Watch out for

  • Sauna closed Monday and Tuesday
  • Popular - early slots go quickly

GLOUCESTERSHIRE · CHELTENHAM

Cheltenham (Sandford Parks) Lido

A winter Nordic Spa with three saunas and an ice room

  • Winter wellness trips
  • Group sessions
  • Ice-bath curious
4.0 / 5
  • Saunas Three
  • Cold plunge Two (weekdays)
  • Ice room From Jan 2026
  • Season Winter run
Sandford Parks Lido in Cheltenham runs a Scandi-inspired Nordic Spa over the winter in partnership with Black Box Saunas. The setup is unusually generous: three saunas to choose from, two cold-plunge tanks on weekdays, the main pool open for cold dips at weekends, and an ice room added in January 2026. It is a seasonal experience rather than a year-round fixture, so check the current run before planning a trip.

What we liked

  • Three saunas plus cold plunges and an ice room
  • A genuine destination wellness day
  • Beautiful Cotswolds setting

Watch out for

  • Winter-season experience, not year-round
  • Cold plunges are weekday-only

HAMPSHIRE · PORTSMOUTH

Hilsea Lido Reopening 2026

Reopening in 2026 with a revamped pool and new sauna

  • South-coast locals
  • Heritage-lido fans
  • New-facility seekers
3.5 / 5
  • Status Reopening May 2026
  • Sauna New
  • Investment £7.75m upgrade
  • Pool Revamped
Closed since 2022, the historic Hilsea Lido in Portsmouth is set to reopen in May 2026 after a four-year, £7.75 million renovation that adds a new sauna to the revamped pool. It is one to watch for south-coast swimmers who want a sauna closer to home than Saltdean. As with any reopening, confirm the opening date and sauna availability directly before you go.

What we liked

  • Brand-new sauna as part of a major refurbishment
  • Restores a much-loved heritage lido
  • Convenient for Portsmouth and Hampshire

Watch out for

  • Not open until May 2026
  • Facilities unproven until it reopens

CAMBRIDGE

Jesus Green Lido

One of the UK's longest pools, with a sauna

  • Distance swimmers
  • Cambridge visitors
  • River-side relaxing
4.0 / 5
  • Pool ~91m, very long
  • Sauna Yes
  • Setting Riverside park
  • Operator Better (GLL)
Jesus Green is one of the longest pools in the country at roughly 91 metres, set in a riverside park near the centre of Cambridge and run by Better (GLL). It now offers a sauna, which turns a long open-air swim into a proper contrast session. The sheer length makes it a draw for distance swimmers who want room to stretch out before warming up.

What we liked

  • Exceptionally long pool for real swimming
  • Sauna on site
  • Central Cambridge, riverside setting

Watch out for

  • Seasonal opening for the main pool
  • Busy in peak summer

HAMPSHIRE · PETERSFIELD

Petersfield Lido

A community open-air pool with a sauna

  • Family swims
  • Community-run venues
  • Quieter sessions
3.5 / 5
  • Pool Open-air
  • Sauna Yes
  • Run by Community
  • Area East Hampshire
Petersfield Lido is a community-run open-air pool in East Hampshire that lists a sauna among its facilities. It is a smaller, friendlier option than the big-name London lidos, and worth a look if you are in the area and want a quiet swim-and-sauna without the crowds. Check the seasonal opening dates, as community lidos often run a shorter season.

What we liked

  • Community feel, fewer crowds
  • Sauna on site
  • Good for families

Watch out for

  • Shorter seasonal opening
  • Fewer facilities than the major lidos

How do lido sauna sessions work?

Most lido saunas run on timed sessions you book in advance, though some - like Saltdean - also take walk-ins. A typical cycle is 10 to 15 minutes in the sauna, a short cold dip in the pool or a plunge tank, then a few minutes to cool down before repeating two or three times. Bring a swimming costume, a towel for the sauna bench, flip-flops, and water to rehydrate. For more on doing this safely, see our guide to sauna and cold plunge.

Are lido saunas open all year?

It varies by venue. Some saunas are winter-only because demand peaks when the open-air water is coldest - Parliament Hill closes its sauna for summer, and Cheltenham runs a seasonal Nordic Spa. Others, like Brockwell's indoor sauna and Saltdean, operate across more of the year. Because the City of London Corporation and other operators change session times by season, always confirm on the official page - for example the City of London's Parliament Hill Lido page - before you travel.

Frequently asked questions

Q01Which UK lidos have a sauna?
In 2026 the best-known lido saunas are Brockwell and Parliament Hill in London, Saltdean near Brighton, Cheltenham's Sandford Parks Lido (winter Nordic Spa), Jesus Green in Cambridge, and Petersfield in Hampshire. Sea Lanes at Canary Wharf is due to open in summer 2026, and Hilsea Lido in Portsmouth reopens with a new sauna in May 2026.
Q02Is the sauna included in the swim price?
Usually not. Most lidos sell sauna sessions separately from pool entry, often as timed one-hour slots. A few combine them, but assume you will pay for the sauna on top of swimming and book it ahead, as popular sessions sell out.
Q03Do lido saunas have a cold plunge?
Some do. Saltdean has a dedicated cold-water plunge and Cheltenham runs cold-plunge tanks on weekdays. At others, the cold side of the cycle is the lido pool itself - which is often unheated and genuinely cold, especially in winter.
Q04Can children use a lido sauna?
Often not. Parliament Hill's sauna is restricted to adults 18 and over, and many venues set a minimum age for heat sessions even where children can swim. Check each operator's age policy before booking.
