The rear of that is the same as the rear of our Turin.
There are five of us using it and no problems at all, indeed for us it's proved to be better than our previous end washrooms. Just a case of drying the shower out each use.
Either use a microfibre cloth or a Karcher window vac. Our toilet is separated by a solid door, which this Eccles is too, you really don't want just a curtain.
