Oooh! Look at me! I've gone and been productive today. In the midst of a tidy blitz, I've taken down the irritating shower curtain before it did the job itself. I'm surprised it stayed up as long as it did - it must have been such a rush job to help sell the place. Both top screws were put in so badly, I have to wonder if they used a hammer rather than a screwdriver. One of them was bent - the other was partially in the wall rather than the funny red plastic doodah you put into walls to screw screws into.
Now I need to get a replacement and a proper shower. Maybe a new sink with built in cupboard beneath to make it fit better with the bath. Oh and mirror tiles above the bath to give the room more width. I have many plans, oh yes.
