To utilise this difficult space to it's full potential, it has been turned into a wet room, with a floating toilet to encourage an airy feeling. The cistern and basin placed on top have been boxed in to create a clutter free zone and there is room to keep day to day essentials to hand. The over-all effect is one of perfect, streamlined calm.
If you have a tight bathroom it's still possible to create a larger shower space. This project used a wet room system. Learn how to design a larger shower in this article http://blog.innovatebuildingsolutions.com/2015/05/09/large-shower-making-bathroom-bigger/
