Saunas and Ice Baths in Liverpool: Hot and Cold

What Liverpool does well: dock water and coastal cold

Liverpool's advantage is that cold water is close to the city. Princes Dock puts open dock water and ice baths directly beside the sauna benches, so you do not walk far between heat and cold. Crosby Beach, a short train ride north, gives you a coastal setting where the water stays cold year-round, whatever the air temperature does.

That is a different proposition from the freshwater plunges common in Finland and the Baltic. There is no lake or river dip here; the cold options are salt water, dock water and manufactured ice baths. If you want to understand the tradition the Liverpool venues are borrowing from, read our guide to the Finnish sauna before you go, because the round structure and the etiquette transfer directly.

Wyld Sauna at Princes Dock: floating saunas, ice baths and dock swimming

Wyld Sauna describes itself as the UK's first public floating sauna, moored at Princes Dock in Liverpool Waters. The setup is two floating saunas with room for up to 36 guests between them, kitted out with handcrafted Finnish heaters and vulcanite stones. One sauna is smaller and quieter, the other larger and more social, and you swim between the two through a designated dock swim area.

The cold side is unusually well supplied for a city venue: a set of ice baths, cold waterfall showers, heated outdoor showers and direct access to the dock for open water swimming. Changing rooms have lockers, hair dryers and swimsuit dryers. The trade-off is a strict swim zone: no jumping or diving, and you stay inside the marked area at all times.

Expect a properly Nordic building rather than a temporary pontoon: thermal alder, handcrafted benches and railings, and a layout that puts the water at the centre. Views back over the Liverpool waterfront come with the heat. That combination of floating saunas and a dock swim is what makes this the most distinctive hot-cold session in the city.

How a Wyld session runs: one hour, booking and what to bring

A Wyld session lasts one hour, and you use that hour as you like, alternating heat and cold. The venue suggests roughly 15 minutes in the sauna, one to two minutes in the ice, then repeat, and it recommends 8 to 15 minutes per round for beginners and up to 20 minutes for experienced sauna-goers. Shower before entering the sauna, and again after leaving it and before the ice baths.

Book online, and note the practical limits. The booking system opens slots up to 42 days ahead, and changes or cancellations within 24 hours of a session are not accepted; cancellations made earlier are issued as credit, with a card refund available on request by email. Every guest must be 18 or over, photo ID may be requested, and the venue is cashless.

Bring swimwear, a towel to sit on in the sauna and a towel to dry off after the plunge. Flip-flops, a water bottle, a bathrobe for the cafe and toilet trips, and a sauna hat are optional extras. No shower gels, shampoos or essential oils are allowed on site under council and safety rules; Himalayan salt scrub is provided by the showers instead.

Lockers come with combination or keyed locks, and a lost or unreturned key carries a charge of £12. Keep valuables to a minimum and secure everything before you head to the saunas, ice baths or dock.

Mersea Sauna at Crosby Beach: wood-fired heat and a cold plunge tub

Mersea Sauna sits by Crosby Beach at the Lakeside Adventure Centre on the Sefton Coastline, a wood-fired Scandinavian-style sauna rather than a floating one. It runs a traditional wood stove with hot coals and reaches 80–100°C. The cold option is a plunge tub on site, backed by access to the Crosby Lakeside facilities, with changing space inside the sauna building.

This is the better pick if you want a quiet, land-based sauna with a sea-air setting and a proper wood-fired heat rather than an electric one. The trade-off is that you are outside the city centre: the beach location means a coastal walk and a train back rather than a five-minute stroll to a dock. Check Mersea Sauna's own booking page for session times and availability before planning the trip out.

Crosby's coastal water stays cold year-round, so the plunge is a genuine shock even in summer, and the wind off the Sefton Coastline can make the walk between heat and water brisk. Pack a warm layer for afterwards and something to stand on.

Indoor alternatives: hotel and spa saunas with plunge pools

Several Liverpool hotels and spas list Finnish saunas alongside pools and cold features, which suits a short visit or a wet afternoon. The Municipal Spa on Dale Street, in an 1868 heritage building, lists a Himalayan salt sauna, steam room, laconicum, ice experience and plunge bucket among its thermal facilities. Maya Blue Wellness at the Titanic Hotel, set in the brick arches of Stanley Dock, lists a hydrotherapy pool, sauna and steam room.

Two more appear in the same directory. Crowne Plaza Liverpool Harbour Health Club has an 18-metre pool with River Mersey views, a spa pool, Finnish sauna and steam room, and notes day access alongside hotel residents. Eforea Spa at the DoubleTree lists an aroma steam room, Finnish sauna, whirlpool and hydrotherapy pool, with thermal facilities available to spa guests and hotel guests for an hourly fee.

Treat these as pool-and-sauna sessions rather than cold-water plunges. Where a plunge bucket or ice experience exists it is a short cold hit, not a sustained immersion, and access rules vary, so check how each venue admits non-residents before you go. For a fuller comparison of hotel and public options, the wider saunas guide covers the rest of the city.

There is also a private infrared sauna and cold plunge offer in Liverpool aimed at solo, double and triple bookings. It is a warmer, more controlled format than a wood-fired sauna, and worth knowing about if you want a private room rather than a shared bench.

Which is better, a sauna or an ice bath, and how to pair them

Neither is better; they do different jobs in a session. Heat is where you spend the time, sitting through a round of 8 to 20 minutes depending on experience, while the cold is a short, sharp finish of one to two minutes. The point of pairing them is contrast, so structure your session around repeats rather than one long bake and one long soak in ice.

A simple pattern works at both Liverpool venues: heat until you are ready to leave, cold until your breathing settles, then a short rest before going back in. At Wyld the cold is the ice baths or the dock; at Mersea it is the plunge tub. Three rounds fits comfortably inside a one-hour floating session.

If you are weighing up a different city break, the same hot-cold logic applies elsewhere; our guide to saunas and ice baths in Cardiff covers another dockland setting with similar constraints on time and changing space.

Booking, prices and timing

Wyld Sauna takes bookings online through its own system, with slots open up to 42 days ahead; its site shows current session prices and any bulk-buy discounts on the Wyld Card. Mersea Sauna's rates and session times come direct from Mersea Sauna. For both, weekend and evening slots go first, so book a weekday daytime session if your dates are flexible.

Cold water in Liverpool does not warm up much in summer, and the docks and coast are exposed to wind, so a bright July day is not a warm swim. Build in time to dry off and warm up afterwards rather than sprinting for a train.

What to bring and how to behave in a shared sauna

Bring two towels: one to sit on, one to dry with. Add swimwear, flip-flops, a water bottle and a warm layer for the walk back. At Wyld, leave shampoo and shower gel at home because products are not permitted on site, and use the salt scrub provided by the showers.

Shower before you enter the sauna, sit on a towel, and keep the door closed so the heat holds. Sessions at Wyld are shared and the saunas are mixed, with swimwear worn throughout. Keep conversation low in the quiet sauna and save the chat for the larger one or the dock.

Cold-water safety: one plain set of rules

Stay hydrated, skip alcohol before bathing, and leave the sauna or the cold water immediately if you feel unwell. Ask a doctor first if you have a heart condition or are pregnant. Enter cold water deliberately rather than jumping, stay inside the marked swim zone at Princes Dock, and never swim alone in open water.

Getting to Princes Dock and Crosby Beach

Wyld Sauna is at 12A Princes Parade, Liverpool L3 1BG, on the waterfront and walkable from the city centre. The closest public parking is Princes Dock Multistorey Car Park at 4 William Jessop Way, L3 1DL. Liverpool's buses and trains serve the waterfront, but check the timetables for the day you travel.

For Crosby, the Lakeside Adventure Centre sits by Crosby Beach on the Sefton Coastline, reachable by train from central Liverpool and then a walk to the coast. It is a half-day trip rather than an add-on to a city-centre visit, so pair it with a beach walk rather than squeezing it between other plans.

Plan Your Visit

Choose Wyld Sauna for a city-centre session built around dock water, ice baths and a one-hour slot, and Mersea Sauna for wood-fired heat by the sea with a plunge tub beside it. Both reward booking ahead and bringing more than one towel; neither needs a car if you plan the train or the walk.
