Shower pan to wall transition (How?)
Comments (4)dave, a couple of things: "There is a former Kerdi seller who now carrys ProVa-Mat who whines on every forum about how they took his bread and butter, but he made one good point- Kerdi doesn't want you to use modified thinset because it isn't faced to accept it well. " Kerdi doesn't want you to use modified not because "it isn't faced to accept it", they don't recommend using modified because the latex modifiers need exposure to free air to dry. The portland cement portion of the thinset cures via a chemical reaction...no drying or exposure to air is needed. But the latex modifiers found in modified thinset need exposure to free air to dry. When thinset is sandwiched between a sheet of Kerdi and a porcelain tile, the only air exposure is through the grout lines. Small tiles that would result in a lot of closely spaced grout lines, you might be okay. Large format tiles with few grout lines and little exposure to air, not so good. If you were to just smear modified thinset on Kerdi and let it cure, you'd find it will adhere quite well. The Kerdi thread you like with no photos and the Kerdi thread you dislike with photos are essentially the same thread showing the exact same steps. You wrote: "I also found this kerdi thread that has pictures...but he doesn't go up the walls from the floor with the membrane, instead he seals thinsets at the floor/wall transition- not recommended. " The method in that thread is correct. With Kerdi, any membrane overlap or at least 2" is correct and watertight. Remember you can have a 2" seam on the floor slope itself...there is also an overlap seam where every Kerdi floor membrane seals to every Kerdi Drain. Any Kerdi seam is fine as long as it's at least 2" of overlap. Kerdi doesn't have to be "lapped for drainage" like other membranes. "I am putting my mortar bed on a concrete slab. Do I need anything between concrete/mortar to prevent the slab from sucking the moisture out of the mortar before it cures properly? " You still want a slip sheet between the concrete slab and the slope. A sheet of 6-mil poly or tar paper will work fine. I've never used ProVa-Mat. Whichever membrane you use, just follow the manufacturer's installation instructions. I understand you're using cultured marble on the walls. Are you using it on the sloped shower floor too? Or will the sloped floor be tiled? If the floor slope will be covered with CM, how are you planning on sealing the seams between the sheets of CM?...See MoreShower pan help
Comments (8)I don't have experience with that specific base, but we are using the Kohler Acrylic Ballast base for our new shower. We have not installed it yet, but have it unpacked already, so I have an idea of how the bases work. Are you talking about having pony walls on the two short 20-9/16" sections of the base? If so, then no, I would not think you would want to install a wall on top of the base. You are supposed to add your drywall inside the base on the two long (42") walls in the corner. I think the simplest solution would be to use glass on the other 3 "walls". Dreamline has some larger corner shower bases. I don't think you would want to install a pony wall on top of that base either. I think the installation would be the same as the Kohler. We actually bought a Dreamline base also because we were hoping it would solve a joist in the way problem we were having. It did not, so we solved the problem a more painful way and are using the Kohler base which is a little nicer. However, the Dreamline would have been acceptable if it had worked. They get good reviews (and are cheaper than Kohler)....See MoreMud Pan/curb height in tile shower
Comments (52)So you found another video doing things incorrectly. Just proving my point about youtube. "his incorrect statement that you MUST bring the backer board over the lip. " That is a factual statement. It is the only approved detail, TCNA (Tile Council of North America) #B413-19, B411-19,B440-19. B412-19, B419-19, B425-19,B430-19, What do you have to back up your point? The tub manufacturers diagram is not approved by TCNA. I'm using facts that are verified in writing. You are believing misinformation on youtube. Meh. I saw a video where he just plunks the CBU down on top of the tub deck and installs it instead of leaving a small gap as you're supposed to. You provided above the link to the video you had issues with. First there is not a CBU in the video. CBU stands for cement backer unit. He is working with a foam board. He talks about CBU's and states to leave a gap for sealant and also states sealant with the foam board. Don't care who calls him out. I'll stick to facts. I'm trying to show you the bad information that's out there. Yet you insist on believing it. For one moment did you consider Sal, myself and TCNA are correct? The only point you have proven to me is you would prefer a high quality video with bad information over a poor quality video with correct details....See MoreShould plywood underlayment for linoleum continue under shower pan?
Comments (28)When we had the shower/tub one piece thing removed in order for a cast iron tub and then tiled shower surround walls put in, the guy who did the demo of the old stuff was the one who had the qualifications to also correctly install the cast iron tub - the difficult part came when the guy doing the tile got involved in the project. If the cat hadn't managed to find her way inside the walls around/underneath the lip of the tub while he was out at lunch, and was too scared to move when he came back and got started up again making all the noise and whatnot - I probably would have never known that the water-resistant drywall he was putting up wasn't actually attached to any of the wall studs (he used random pieces to attach it to instead, but none of that was secured to wall studs either...yeah, I know...makes no sense but that's how it was!) ...so in a way I'm thankful to that cat for getting into a situation that required me to carefully take down each and every piece of drywall that he'd finished by the end of that first day, he'd only left a space around 10" wide by 18" tall with only some kind of paper stuff there which is how I'd figured out where the cat had gotten to in the first place (the paper wasn't as muffling as the drywall was so while I knew it sounded like she was somewhere in between the lower and upper floors, I had to go in and listen by the papered section to really figure it out). If the cat hadn't gotten trapped I'd have gone in to take a shower one day not long after the job had been completed and had an avalanche of tile fall down on me because the drywall wasn't secured and was installed with all that tile weight in a 'wet area'. Just because someone does installation of a given thing for the house for a living doesn't mean that they're necessarily going to know all the things there are to know about a particular thing that happens to be the thing you want them to install for you. It's also possible for someone who has been in the business for decades to get into certain habits when they do a job and become extreeeeeeeeeeeeeemely resistant to any newfangled ideas about how things should be done - ideally this is where the instructions from a manufacturer would help out, but considering how...unclear...those things can be, and how strongly manufacturers feel about having to shell out to customers when something goes wrong (why else would they provide hazy-at-best details on how to install things, along with a bunch of fine print that trust me, IS ALL THE EXCLUSIONS that will mean they don't have to pay anything for the failure of their product...and homeowners must sift through an assortment of professionals, put those professionals through an obstacle course designed to weed out all but the best for their particular job, pray that they can afford that best option, etc etc)... :P...See MoreUser
