Designer Ethan Lai has put a radical new spin on the bathing with his 90 Degree bathtub design. The 90 Degree bathtub is a stand-up bathtub that also functions as a shower and a steamer.
The 90 Degree bathtub can fit one and releases its water from a shower head. The design has touch controls that let users choose between the three different bathing styles offered. Small vent holes at the top of the chamber release steam to ensure that you can still see yourself through the steam. The 90 Degree bathtub was designed for the Roca Competition and is meant to be used in the near future when cramped conditions force humans to do everything while standing upright.
