Hi, does anyone have a shower ledge like the one pictured? If so how do you find it? How was it built? What are the pitfalls? I have a narrow bath in a beach house.Shower is cramped but if we want to retain bath. Don’t want separate shower. I am thinking of moving bath forward and putting a std wall stopped by a 15cm ledge at just under an arms length from edge of bath. Possibly buying new 800 wide bath.This would give a place to put shampoo, glass of wine plus elbow room when standing. Particularly concerned about potential for leaks. Was thinking wood effect architrave floor tile for shelf with white subway/ grey grout on walls and bath panel
