Hi,

I just remodeled my master bath it is upstairs, and the plumber/tile guy that did the shower pan never came back. I started thinking there was a problem, so I did research and came to your site.

First he did lay 2x12's between the studs and put down roofing felt. But what he didn't do was use a mesh/lathe over it, and used some kind of concrete mix under the water tight membrane? Also until doing research did not know about deflection and proper support. (I have 2x12 supports and they are about 16 inches apart and 16 feet long, I know this because about two month ago the sheetrock was just replace, textured, and painted.

He did use a 3 piece drain. When he didn't come back, I have decided to finish it. I layed a mesh/lathe above the presloped membrane and only nailed the mesh outside the curb. I used the 60 pound bag of sand topping mix and added about 30 pounds of playsand to get the 1 to 5 ratio (as found on this site). I am adding a cement block bench also. The dry mortar mix seems to have dried and hardened. Here is where my questions come in:

1) How much of a concern should I have about the preslope that the plumber/tile guy constructed?

2) The dry mortar bed I have just completed seems to release a lot of little bits of sand if I run my hand over it, is this normal?

3) And I've gone the the big home improvement stores to look for a thin set mortar to lay the tile over the shower floor, but when reading the labels all of them say NOT FOR SHOWER FLOORS. Which dry-set mortar can I use over the dry mortar bed that is for shower floors?

I am putting down traventine.

And another question (hope this is not to long) a built a shower nitch. All I did was between the studs a created a space put down horizontal 2x4 for the horizontal part of the nitch. I covered the nitch with roofing paper, then used easy board (screwed in) to the frame of the nitch. I was going to use silicone sealant to put around the joints, but am not sure that this is the best way to do it.

Well thanks for any responses you can provide.
