I've got 2 issues with the new shower floor and bench I did myself.
I did tons of research before attempting it and found the advice to be sparse if much at all.
1- the corner edges are impossible.
2- I have sealed the River Rock 2x with the experts recommended product, but the rock still sucks in the grout. I am literally wiping each rock with a cloth on my finger, quick as I can before it dries. Help!!
