A towel bar should be hung as close as possible to the bath or the shower. If there is a bath and a shower in a bathroom, the possibility of two towel bars should be considered. If space is a limited commodity in your bathroom, a good option is to have the towel bar installed on the door of the shower. Another option for small spaces that are used quite regularly is to rather install towel hooks on the back of the bathroom door. If you have too much space and a very large shower, some towel bars are also installed inside of the shower, furthest away from the shower head.
