The peculiar thing about shower design is that showers are the location where your end user (the person taking the shower) is in the most vulnerable position.

On a physical level, well, the user will be naked (let’s forget about weirdos for a second) and might easily get burnt by hot water if your shower does not offer any protection against accidental changes in temperature. In the winter, you also need to take into account that users will often freeze their ass because of a draft coming from the bedroom, which means they stop being comfortable until they have reached that sweet temperature spot under your shower.

On a psychological level, the user is also in a very vulnerable state. Even in an intimate context, hanging around naked is rarely the most comfortable situation for most people, especially when they are in a place they don’t know that well (ex. a hotel room many miles away from home). Some showers are also designed in a way that they make it impossible to change the water temperature while remaining outside the shower to circumvent the issues mentioned above.
