This layout is a very impractical use of the bathroom, however it does still contain the products that the bathroom requires, therefore surely it is still a 'functioning' bathroom. The shower swing-door faces out and replaces the existing timber swing-door into the bathroom. One can simply step from hallway into the shower.
The bath is angled at 45degrees off of the shower back. The drains of both the shower and bath are close together for plumbing purposes, however the user would have to sit facing the shower. The bath tub sits between the shower cubicle and the two walls - the wall between the bathroom and my sister's room and the outside wall.
The towel rail is located on the other side of the bath tub, making use of what would be wasted space. It would be rather inconvenient for the shower and sink though.
The shower faces out of the bathroom into the hallway, and the sink behind it. It would be difficult to access the sink apart from through the door to my sister's bedroom.
