Thanks for that. It just occurred to me that the last homeowner left a binder with some info on the house. It turns out the whole slab blueprint was in it. Bad news is that I had attached some studs to my patio. I thought it was added on. It appears it is part of the main slab and there are cables running through it. I used ancors and they were pretty deep. I hope I didn't mess anything up.

Have you done your own shower before? I did my last one 3 times :0

Make sure that you use a liner with no breaks and that it goes up the wall at least 8". I also recommend that you use wonderboard and seal that with a tar based paint product before laying any tile.

Now for the 'real' advise, and what my wife would recommend; pay someone who knows what they are doing. It's not that it's really that hard, but if you miss any step, and I missed a few, you have to tear is all down and start again. Pros get it right the 1st time. So it basically costs about the same, unless you hit it perfect the 1st time.

I have not done a shower before. I bought some of these things called pre-pitch, quick-pitch, and kirb-perfect. I've also watched quite a few videos. The best lesson I have learned is that I should not do it the way the idiots did it before me. They nailed and screwed the liner on the inside of the shower pan as low as 1/2 inch up. They didn't put any slope under the liner. They used only 12 inches of backerboard behind the tiles with the rest being drywall. They had the weep holes filled with mortar.

I have hope that I will do better. Wish me luck.

I am sorry I do not have an answer for you. I would also like to know though. I would think there has to be a way to do it safely.

Good luck OP and sorry I am no help.

I wish they had stamped that notice before screened in my patio.
