Floating Saunas in Liverpool: WYLD vs Crosby Cold-Plunge

What floating saunas in Liverpool actually means

In Liverpool, the floating part refers to the structure, not the bathing. WYLD's pontoon sits in the water at Princes Dock, so you step off the quayside into the sauna and cool down using ice baths and waterfall showers on board rather than jumping into the dock itself.

The rest of the city's cold-water sauna scene is land-based. Mersea Sauna is a wood-fired unit beside Crosby Lakeside Adventure Centre, and its cooling option is a cold tub rather than open water. For a wider survey of the city's rooms, from dock-side pontoons to suburban swimming halls, our guide to the best saunas in Liverpool is the place to start.

WYLD Sauna at Princes Dock: the floating Nordic sauna

WYLD occupies a floating pontoon in Princes Dock, part of the Liverpool Waters district on the city's northern waterfront. The sauna room is built for 30 people, which makes it a social, communal space rather than a quiet one, and the outdoor seating lets you cool down in the dock air between rounds.

The cold side is unusually well equipped for a floating build: two ice baths, two cold waterfall showers and four heated outdoor showers, so you can alternate between plunging and warm rinsing without leaving the pontoon. Changing rooms come with lockers, hairdryers and swimsuit dryers, which matters when you are heading back out into Liverpool weather in wet swimwear.

Inside a WYLD session: heat, ice baths and cold showers

Treat WYLD as a multi-round visit rather than a single sit. A typical pattern is one round in the hot room, then a cold waterfall shower or a short dip in an ice bath, a warm outdoor shower, and a rest on the seating outside before going back in. With 30 seats the room absorbs groups well, so a first visit with friends is easy to organise as one booking.

Because the pontoon sits on dock water rather than a lake or the sea, the cold comes from plumbed ice baths and showers, not from a swim. That makes it a controlled choice for anyone who wants cold exposure without dealing with tides, currents or a walk across a beach to reach the water.

Mersea Sauna at Crosby: the wood-fired alternative by the sea

Mersea Sauna is a handcrafted wood-fired room at Crosby Lakeside Adventure Centre, next to the boating lake and a short walk from Crosby Beach. The stove heats the room to between 80 and 100 degrees Celsius, with a sand timer inside so you can track your rounds; the house recommendation is five to 15 minutes in the heat before cooling off.

Capacity is six seats, and you can either book a single seat alongside other bathers or reserve all six for a private session of up to eight people. The booking includes use of the changing rooms, lockers, showers and toilets inside the Lakeside Adventure Centre, plus heated outdoor showers near the sauna, and parking at the centre is free for sauna users with a permit from reception.

The setting is coastal rather than dock-side: you are on the Sefton Coast at Crosby, close to Waterloo station, so this is the better pick if you want sea air and a beach walk around your session. It is an outdoor sauna in feel and location, and the wider list of outdoor saunas in Liverpool covers what else is available beyond the city centre.

How a session works: booking, length and mixed company

Mersea runs 50-minute slots and takes bookings online, either as an individual seat or as a full private hire of the room. Expect to share with strangers if you book a single seat, since the sauna holds six seats, and reserving all six is the way to secure a private session.

The Crosby session structure is a useful model for pacing any first visit: several cycles of hot and cold, with five to 15 minutes per round in the heat and a cool-down in between. Because slots are fixed, plan your arrival a few minutes early to change and shower, and leave time for a slow finish rather than rushing out at the end of the hour.

Swimwear, towels and what to bring

At Mersea, swimwear is the rule, and the bring-list is short: a small towel to sit on, a larger towel to dry off with, and swimming trunks or a costume. Shoes come off and you shower before using the plunge tub, and a water bottle is worth packing, though glass is a bad idea in a hot room.

The seat towel is the habit worth adopting everywhere: lay it on the bench so sweat stays off the wood, then take it with you when you leave. WYLD's changing rooms provide lockers and dryers, so you need less kit than you might expect, but a towel of your own and a dry layer for the walk back are still sensible.

Prices and how to book

Mersea publishes its rates: one 50-minute session is £15, and there are discounted block bookings of 10 sessions for £120, 20 for £225 and 30 for £315. For groups larger than eight, or sessions outside normal opening hours, contact the sauna directly via Instagram or email info@merseasauna.com.

WYLD's session prices and booking arrangements are set by WYLD Sauna itself, so check the WYLD Sauna Liverpool page for the current offer before you plan a visit.

Cold water and the Finnish tradition

The rhythm at both Liverpool venues follows the Finnish sauna pattern: hot room, steam from water on the stones, then cold and a rest. Mersea describes its stove as a Scandinavian setup using Löyly, the burst of steam created by ladling water onto hot rocks, which is the same logic you meet across Finland and the Baltics.

If you have only used infrared cabins or steam rooms, the difference is worth knowing in advance. A wood-fired or traditional Finnish room runs hot and dry at roughly 80 to 100 degrees Celsius with steam on demand, while steam rooms sit much lower and wetter and infrared cabins heat the body directly.

Getting there: Princes Dock and Crosby

Both venues sit on the Merseyrail network. WYLD is at Princes Dock in the Liverpool Waters district, a walk from the waterfront stations at the northern end of the city centre, while Mersea is at the Lakeside Adventure Centre in Crosby, a short walk from Waterloo station towards Crosby Beach.

Driving is straightforward for Crosby: parking at Crosby Lakeside Adventure Centre is free for sauna users with a permit from reception, and there is free on-street parking around Crosby marina. For a city-centre floating session, arriving on foot or by train avoids paying for dock-side parking.

Season, weather and the honest trade-offs

Mersea's heat and cold tub work in any weather, but the Crosby site is open-air in character, with a short outdoor walk to the heated showers and sea air on the way in. Pack a dry robe or warm layer for afterwards; you will feel the difference between a summer session and a January one on the walk back to the centre.

WYLD's trade-off is scale. A 30-person room gives you space and a lively atmosphere, but it is not the place for silence, and the changing area serves the whole pontoon at once. Mersea's trade-off is capacity: six seats means sessions can fill, and the small in-sauna changing area is a squeeze for a full room, so arrive changed where you can.

Safety and etiquette in a shared sauna

Shared saunas run on a few simple courtesies: shower before you go in, sit on your towel, keep the door closed, and ask before adding water to the stones if others are in the room. Keep rounds short, five to 15 minutes is the usual range, and leave the heat as soon as you feel uncomfortable rather than pushing through.

Stay hydrated, skip alcohol before bathing, and step out if you feel unwell; anyone with a heart condition or who is pregnant should speak to a doctor before using a hot sauna or a cold plunge. The same applies to the ice baths at Princes Dock, where the cold hits hard and fast.

Which Liverpool Sauna to Choose

Choose WYLD at Princes Dock for the floating experience, a large communal room and proper ice baths and cold showers on the pontoon. Choose Mersea at Crosby for wood-fired heat, a cold tub, a beach-side setting and a simple per-session price that makes a first try easy to budget.

Either way, book ahead: Mersea's six seats go as private hires, and WYLD's sessions are run by WYLD Sauna, so check the venue's own site for current slots and what to bring before you travel across the city.
