My name is Gary. I have read through a lot of the back threads and this seems like a really great forum.

I am building a 3'X4' tile shower on a frame floor with a crawl space. The floor system and decking are solid. I need a little help with the shower pan. I am using a pvc liner. How thick do the preslope and the deck mud need to be? If I use mortar mix with a latex admix for the preslope will 1 to be sound? I intend to use sand mix for the deck mud. Once again how thick will it need to be? Do I add wire reinforcement mid way?

Hi Gary, welcome. I like to set the bottom section of the drain about 1/2-3/4 above the plywood floor. Then I staple down felt paper and wire lath to the floor, make the cement flush with the top of the bottom drain flange. The top layer of mud that goes over the pan needs to be 1 1/4 thick at the drain with 1/4 inch pitch. :)

Check out the "shower construction info" thread in the liberry, good reading there. :)
