- I noticed in the shower there are 3 big slaps of some metallic looking material on the walls and floor. What is that? What's it called? And for the one on the floor, does the add more friction so the shower becomes less slippery? I think it looks awesome and I'm considering adding that but I want to know what it is.
Domingo this is how we want the shower to look. Including the 2x niches you can adjust as needed but need to hold big...
