London now has a floating hot tub boat ride, known as The HotTug, which takes people along Regent's Canal.
The water in the hot tub is heated with a wood-burning stove and powered by an electric motor. Each ride lasts around 90 minutes and costs £220 per boat.
Each boat can seat up to 7 people.
Business Insider UK went along to the launch party at Islington boat club.
