The UK's first 50-metre floating pool, Sea Lanes Canary Wharf, opened on June 19, 2026, in London's financial district. Built at a cost of £4.5 million, the lido offers a unique swimming experience with naturally filtered water from Eden Dock, separate from the River Thames. The facility includes two renewable-energy-powered saunas, a clubhouse, food stands, and a bar.
Ticket Prices and Activities
Swimming-only sessions cost £10 for one hour, while swim-and-sauna sessions are £18. The site also offers paddleboarding, freediving, aquathlons, triathlons, and open-water events. The water is unchlorinated and maintained at 16°C, with quality rated as "Excellent" under EU Bathing Water Standards.
First Impressions and the Cold Shock
Upon arrival, the reporter saw a stand with hanging wetsuits, which came as a shock. "Without doing much prior research, I didn't anticipate the water being so cold that wetsuits would be on offer," she said. Despite seeing many swimmers without wetsuits, she opted for one after observing a man struggling with the cold. The wetsuit proved insulating and high-quality, keeping the cold at bay.
Swimming Experience
The lanes were slightly narrow, but the reporter adapted by watching for fellow swimmers' hands. The water has a natural green tint to support aquatic life, with reduced visibility compared to chlorinated pools. The Olympic-length pool caused breathlessness, which the reporter attributed to the 16°C water. "The swim itself was truly refreshing," she noted.
Saunas and Post-Swim Relaxation
The saunas were spacious and initially at around 60°C, but heating up quickly when water was poured on the hot stones. After the sauna, the reporter and her friend enjoyed a pint at the bar, describing it as the best-tasting IPA.
Overall Impression and Suggestions
The reporter praised the "one-stop-shop" experience, as her friend noted: "You start with the swim, then you go to the sauna, then to the showers, and immediately outside, there are bars for your hydration needs. I think it's definitely very well thought out." However, they suggested adding water dispensers near the pool, swimming costume spin dryers, and a large display showing the current water temperature at the entrance. Despite the cold, the reporter said she would visit again, especially during the current heatwave.
