    Just like to thank everyone one in advance for all the help I've received over the years from this site, even though I'm just now registering to post.

    Here's my situation. I'm at the beginning stages of a small bathroom remodel. The house is a 1961 Southern California track home on a slab. I've decided that hot mopping my small 36" x 38" shower, then following with a floated wall will be the best way to tackle this out-of-square shower. Which leads me to the drain. I know the shower was originally hot mopped when built, by seeing evidence of tar around the frame. Unfortunately, a neighborhood handyman got to my shower and added a PVC liner pan and hardi board backer walls before I purchased the house about 4 years ago. When sealed the pvc liner to the drain, it appears that filled up the weep holes with silicone sealant. Of course, since he was probably learning on my house, it leaked through the curb, rear walls and under the liner.

    So, my plan is to keep the lower portion of the embedded Insta-set drain and add the Ebbe square drain with adapter to use with the hot mopped floor. I've included a few pics that show the pre-sloped floor which is actually formed into the slab. It also shows the condition of the drain. What do you guys think? I don't have draining issues between this shower and the main line. I also don't want to demo the floor if I don't have to.

    Yes... It comes with a new upper half of the clamping drain, which acts as the adapter for the Ebbe square drain assembly. I'm placing my order tonight, so I'll have a better idea of how it works once it gets here.

    Hot mop is really old school for a shower, but still will be approved by your inspector.....standard practice calls for THREE layers of felt. See the Tile Handbook from the American Tile Council. http://tileusa.com/

    If you need help on how to preslope your mud bed, good advice is available at the tile forum www.johnbridge.com

    I tried getting quotes for schluter type systems, but it seems like every tile man i called still does hot mop and floated walls type
    tile jobs. Just doing a search of the yellow pages comes up with no less than 10 hot mop only businesses in my area.

    Thanks for the tips on the current code for hot mopping. I' ll make sure the licensed company i choose uses the correct standards.

    I've been trying to ignore Whipple since we ran him off as a trouble-maker a couple years back. John is a DIY'er who over the past few years has proclaimed himself an expert in the building trades, and he has a chip on his shoulder. :)

    If you wanted to use Kerdi, and already had a clamping drain in place, they sell an adapter that screws into the base of the drain to accommodate the Kerdi to create the waterproof connection. Once the waterproof membrane is covered up with the wear surface (the tile), it's thickness is irrelevant, and thinner makes less obtrusive seams and folds. All of them can work well, if installed properly.

    re-using old drain for hot mop

    Hi Killer, We hot mop hundreds of showers every month. We get asked this question often. If this was on a second floor we would highly recommend you change out the drain. However, on first floor slab it is not as risky. You just want to make sure that the new top half of the drain you are buying fits perfectly over the old bottom flange. We have seen showers leak in between the halves because the two pieces don't sandwich together nicely. You can find more info on hot mopping and shower pan articles Here. Thanks! - West Coast Shower Pans

    Those three bolts on the clamping flange may NOT be in a generic pattern, meaning a flange from a different manufacturer may not fit it.
