I can't say that a steam room is the last thing I'd expect to see being towed by a two-wheeler; however, the H3T Bike Sauna is far from the baby seat or the back rack one might be more accustomed to toting.
The eccentric architectural firm has developed this project as one of a couple of experiments with unconventional sauna appearances. The H3T Bike Sauna specifically is a six-seater chamber equipped with two long wooden benches and a wood-burning fireplace. Hot air is kept within the cylindrical cabin thanks to a small slit in the back for entry and exit. Smoke escapes from a tiny chimney, and the entire toasty trailer is being driven around Prague on the back of a bicycle.
