@SpItal_Jeff My advice to you would be to swallow your losses and hire a professional that comes highly recommended through this forum or from word of mouth to get you the wet room you always wanted. You could chase this to the nth degree causing you undue stress, upset and possibly more costs! The chances of you getting anywhere with the tradesman are highly unlikely but that's not to say that you couldn't make a small claims case against him. Having said that, you would have to take steps to allow him to put right his wrongs.
If I were you I would cut my losses and move on. Most of us here have alot of experience in seeing bad jobs that we have to either put right or rip out and redo. I've had customers break down in tears when I visit them because of a bodged wet room because of the stress.
Move on, rip out, refit, get the wet room you envisaged and then hope the cowboy you had trips on one of his own lipped tiles and breaks his neck!!!!
