oh, well then you should be ok. I was concerned with the wall tile being laid before the floor was laid, but I've seen it done both ways on the tile ready pans.
Which brand of tile ready pan did you use? I've only used them 2x's and that was several years ago, I suspect they've come a long way since then. I have a buddy who is an absolute magician with the dry pack....so I don't bother with pans any longer.
On a side note. If you truly are only 18 and did that nice of a job, you will have a VERY prosperous future ahead of you. You clearly have a knack for the details. Stick to the baths and kitchens and you will earn a very comfortable living doing something you enjoy!
