Studio Octopi launched new visualisations of their Thames Baths project at the Royal Academy of Arts today, revealing proposals for two fresh Central London locations on the river.

Designs for sites beside the London Eye and City Hall integrate changing rooms and kiosks within the floating pontoons, which operate as self-contained, floating lidos that can be transplanted onto any UK urban waterway.

As with initial proposals for the project at Victoria Embankment, two pools will be filled with filtered water from the Thames. The long-term aim is to create baths filled with the moving tidal waters of the river following the introduction of the ‘Super Sewer’ in 2023. The new sewage tunnel should make it clean enough to bathe in while a heat exchanger will remove the chill, making it usable all year round.

‘For years I have been saying there is no reason why London can’t make more of the river,’ says the project’s ambassador and artist, Tracey Emin, ‘and what better way to use it than create Thames Baths for the people of London to swim in’.

Access to the decked areas will be free, while use of the baths will cost the same as community pools.

A Kickstarter campaign is currently underway to fund a planning application and launch the baths by spring 2017. It has already raised £70k of a £125k goal, with nine days left to go.
