Cool off in a floating hot tub on the Thames

Hot tub boats glide above the waters of the Thames in London, offering people a relaxing haven in the midst of the capital's stressful routine.

The boat is essentially a floating hot tub, but has an electric motor and a wood-fired stove to keep fresh water at a very pleasant 38 C. It is available for rent. Visitors float down a London canal as passersby watch in awe and they relax and wave.

The idea originated in the Netherlands and found its way to the United Kingdom. The founder of the hot tub boat aims to make it one of the most unique experiences visitors can have in the city.
