19. Heating and Ventilation Control in the Bathroom
Going to the toilet in the cold morning is never fun, and a low-temperature room even keeps us from going to use it. However, it seems like Japanese people have found the solution for everything. In every bathroom, they have installed a control panel. By using this, you can pick the temperature for your bathroom with a timer to make it warn ahead of your shower. Furthermore, it also comes with a ventilation system to let off the steam if it gets too hot.
