KERDI Shower Pan Mistakes and How You Can AVOID Them

I’ve seen many videos say the thin set isn’t water proof allowing water to Penetrate under the KERDI Membrane or penetrate into the subfloor.

I wish all YouTube videos were this well done. Straightforward and to the point without unnecessary talking yet detailed enough to answer all my questions.

I did this at my home 9years ago. Had never used it before and it was great. Zero leaks and its a complex shower with multiple body sprays, rain heads, steam, speakers and lights.

So far one of the best tutorials. Thanks

Great video, thanks Jeff!

Good stuff ! Thank you 🙏🏿

Schluter sponsored my workshop which was awesome. Hotel , meals and happy hour paid in full. I still float traditional fat mud...deck mud showers but info and prep key.

here's another tip mostly for homeowners but contractors sometimes think they don't need to. Read the instructions slowly, carefully and follow them especially if you think you know what they entail. What a simple mistake that would be if a manufacture comes out with a revised product.

Thanks again for all these great and informative videos! Before I install my Schluter shower tray, I'd need to replace a 40"x36' rotten subfloor. Does it matter if the grain of the plywood is parallel to the joists as opposed to perpendicular? I thought since plywood is cross laminated and each layer is of different direction and this is just a small area, it should not matter much. Please advise, Thx!

Another great video! Something I have wondered about before is while installing kerdi fabric or kerdi band, how much of the thinset do you squeeze out with the drywall knife? Obviously you want it embedded nicely. But do tou think it's best apply a lot of pressure or go over it multiple times to get everything you can out, or to go a little more lightly?

Hey Jeff, THANK YOU so much for the detailed info and excellence your videos are about!! I'm 2 inches short on one side of the pan and I have 2 extra inches on the other side. Can I "extend" the shorter side with my 2 extra inches of shower pan and then water proof it to avoid using the dry pack mortar?

I personally like using redgard or hydra ban. With a drypack bed. It's never failed me.

Thanks for all the great videos. I have started a complete gut and remodel of my master bath (my daughters room). Im using kerdi for the first time and have worked hard to make my studs plum. im now ready to set the kerdi board and pan. my shower is 4.5' x 38" including curb. would one 50 lb bag of all set be what id need to mix to set the pan and curb? Also i plan to wall tile to the far edge of the curb so should i meet my kerdi board and sheetrock in the center of the curb and then use kerdi band on that seam? that would allow me to cover that seam with tile and cover the kerdi band also. is this how you would do it? i plan to joing your website.

Great video! I have seen you rip off the 3/4 inch off the perimeter in previous videos, as you mentioned its flat. Im still confused though..... by ripping off the perimeter 3/4 first and then removing say 5 inches off each side and then reinstalling the 3/4 inch is it not at a higher elevation being that the pan is sloped, meaning that butting into the now more narrow and thinner pan this 3/4 inch strip is now abruptly taller leaving almost a step as opposed to a smooth gentle slope?

Thank you for your great videos. I am in the process of my first shower renovation and have followed much of your advice. I have a question regarding my Kerdi pan. While dry fitting it, I stepped on it and cracked the Styrofoam. The membrane itself is fine and the foam backing is still smooth. Would it be OK to still use this or should I replace it? Also, I used GoBoard for the walls and painted over the GoBoard sealant with Red Guard. Can I use Schluter thin set (which is modified) over Red Guard when laying the tile?

When you tile your floor and walls, which do you do 1st? Opinions seem evenly split on this. I would like to do my floor 1st because i need that extra little bit of height for my full tiles to work out to the ceiling. Your videos are great! Thank you!

can i install a shower schluter pan on a shower that has already a shower curb installed? instead of doing a mud bed the pan looks easier since the floor is leveled. but since there is a shower curb installed i was wondering if the thin-set has to squish out of the schluter pan ? or do i have to leave a 1/8 gap on the pan so the excess thin-set can come out?

If I set my Kerdi Shower tray with the Kerdi Trowel, do you foresee any issues with adhesion later on?

Hello Jeff, Can I put another 1/2" plywood over the 3/4 subfloor then install the pan. It give more support I thinks.

Would it work out ok to install the kerdi pan first, then the wall board? This would basically use up the 3/4 flat on the pan perimeter.
