   I prefer Kerdi membrane for large showers.

   Makes it easy to waterproof the entire floor.

   A vinyl pan is out of the question at this point as you've already put rock up.

    

   Kerdi it.

   Mike, Those are my pics, not the original poster's. Kerdi over cement board.And yes, for what it's worth, I did kerdi over the deck mud preslope and used a kerdi drain. Kerdi on the framed in wall niche and even did kerdi on the ceiling.Be orange, Mongo

   Thanks Mongo,

   First time ever to hear about Kerdi. Will see if I can get more info inline. Thanks for the lead.

   Mongo, why Kerdi over CBU? The spec (last time I read) is for Kerdi over sheetrock.

   Overkill.  He builds for the ages.

   I would trust Kerdi over Homasote, if it was rigid enough.

   As you and Herr Schluter know, Kerdi can go over gypsum board. You may need to "educate" your local inspector about using Kerdi over gypsum in wet area. Some allow it, some don't based upon the latest IRC.That said...I do trust the product, I think Kerdi is great. No hesitation on my part in using it whatsoever.Preparing for the worst case scenario? I'd rather use cement backer in a shower than gypsum board.However far fetched it may be, I know that for any moisture problem that may occur inside the wall that cement backer will hold up better than gypsum board.Kerdi is great for steam showers as well, I just would rather have cement board instead of drywall as the substrate for the Kerdi.I'm just using what I think is a better material for not just the known issues, but the unknown as well.Mongo

   It's just that John Bridge swears up and down you should use drywall... dunno why... never done it myself... CBU makes perfect sense for stickin' thinset to it.

   John does great work and his forum is the best thing for tiler setters that's come around in a long long time.That said, he's in TX. He may have different concerns regarding moisture than those in a heating climate (I'm in CT), and there I'm referring to shower walls that are also an exterior wall on the house. Moisture that may somehow get through the wall could condense inside the wall cavity, compromising the drywall from the non-Kerdied side.That shouldn't be a problem, but it's always a possibility, and when it comes to moisture issues, I'm not much of a gambling man.Again, you CAN use Kerdi over drywall.I, as well as a lot of others, simply prefer to use cement board.Mongo

   We have been using Ditra (the floor stuff) for about a year, and I've had to trim/remove tiles twice. I was really impressed with the stick of the stuff, as well as the lightweight ease of installation, so when the shower in my new (to me, c 1930) house started leaking into the kitchen last week, I replaced the entire enclosure with kerdi over drywall, with the kerdi drain. I love the stuff--it's quick and reliable, and unlike CBU actually waterproof. The adjustability of the drain to conform with tile layout and height is genius. I don't reckon' I'll ever build another out of anything else.

   On my job all the showers were done in "red guard"

   I couldn't find the product with a quick search but here is a tile web site talking about red guard.

   http://www.ceramic-tile.com/tileman.cfm/forum/tileman.cfm?start=31&sdate={ts+'2005-03-13+06:52:26'}&sid=0&ssearch=&stype=none

   Here is a pic of a tub I had to set ---- the red guard is on all surfaces.

   whats that fancy set up you have to lift and set the tubs?

   Tub alcove had about 6" clearence around the tub so multiple bodies on the 385lb tub was outta the question.

   That tub went in the 35th floor of a 42story bldg, so concrete decks is a plus to have.

   Put in a 1/2" quick bolt into the concrete & hooked up a standard come-along

   The orange straps are ratchet tie-downs with plastic coated hooks ---- didn't want to damage the tub finish.

   Went a lot smoother than any of us planned."Guns don't kill people----- Husbands that come home early do." Larry the cable guy

   btw .... I've built and worked around some goofy stuff over the years ...

    

   U can do much the same in std construction with a few temp tacked lumber supports ... as opposed to the concrete ceiling bolt deal.

   think outta the box or work a few jobs with my buddy Joe ...

   he's always got another way of making the heavy lifting easier ...

   Home Depot sells the Red Guard, fyi.

   Works great, smells chemically (if that's a word) and spreads with a trowel, taping knife, or even a paint brush, though that might leave it a little thin.
