Tell me what to do with a tiny bathroom

[Ttbb]

It is literally the size of two ba tubs next to one another. No wondows.

Oh yes definitely avoid a door that opens into the room. My last flat had a small bathroom and the door opened out into the hall. It made such a difference. I plan on replacing my current bathroom door with a sliding/folding door

Forget tiles, glass panels are the way to go.

Look at shower baths, only 10com wider and makes the shower end a lot better
