Badweather turns derelict canal boat into London's first off-grid bathhouse

architecture-design · 2026-09-07

The architectural group Badweather has converted a 17-meter canal boat into Soak, which is recognized as London's inaugural off-grid bathhouse, moving locations every two weeks. This 56-foot widebeam has been refurbished to include a wood-fired sauna, two cold plunge pools, showers, changing rooms, and a small bar accommodating up to 12 guests. Operating independently from the grid, Soak sources its water from the canal, utilizing a six-stage UV filtration system, while solar panels provide electricity. Co-founder Leo Sixsmith and chef Riccardo Codacci-Pisanelli spearheaded the extensive renovation of this nearly derelict 20-year-old boat. Founded in 2019 in London by Oli Brenner, Sophie Mei Birkin, and Sixsmith, Badweather is celebrated for its innovative architectural designs. Photography by Kaye Song.
