Hello All,
I currently restore tiled bath & shower surrounds ie regrouting, recaulking, tearouts etc.

Some are in such bad shape because of water damage that its more cost effective for my customers to go with inserts from sterling, american , etc..

I have not installed one of these surrounds as yet. What is the learning curve on installation and what do you consider the toughest part of the install.
I would like to add this capability to my business as an option to my customers.
