Sea Lanes Canary Wharf to open year-round floating lido on the Thames
A 50-metre freshwater pool will float on the Thames with six lanes, year-round booking and two renewable-energy saunas, bringing cold-water swimming into Canary Wharf.
Sea Lanes Canary Wharf will turn the Thames into a permanent swim destination rather than a one-off summer spectacle. The 50-metre freshwater pool will float on the river but stay cut off from the Thames itself, giving swimmers naturally filtered water, six lanes and a depth of 1.3 metres in a format built for everything from family dips to serious laps and cold plunges.
That layout matters because it puts cold-water swimming into a dense urban setting where access is usually the barrier. The pool is being set up for year-round booking, not just seasonal use, which makes it look more like fixed city infrastructure than a temporary lido. With six lanes, it should suit regular training as well as people who want the recovery hit of a brisk plunge without leaving London’s commercial core.
The wider site is designed to push the same idea further. Sea Lanes will include two glass-fronted saunas powered entirely by renewable energy, along with a community clubhouse planned for wellness events and a wetsuit concierge service. Membership and pay-as-you-swim access will both be offered, giving the venue a split identity that can serve committed swimmers while still staying open to casual visitors looking for heat, cold and social space in one place.
The first swimmers are expected on June 19, 2026, and the project arrives as London keeps building out permanent outdoor swimming options rather than treating them as novelty installations. For ice bath fans and cold-water swimmers, the appeal is obvious: lane space, sauna recovery and a booking model meant to work all year, all wrapped into a floating lido on the Thames.
