Noob...transition from drywall to kerdi board

[wwsteel7]

Hi everybody...
So I've framed a new 6x8 bathroom with studs 16 oc...The shower area to be 32x72
The back wall will be full 1/2" kerdi board...but the 2 side walls only 32inches out from back wall...then regular drywall.
How exactly should I transition from the kerdi to the drywall? Im not sure if the seam between the 2 materials should be exactly at the 32inches mark...or if either material should go beyond that mark.
Should I run the kerdi to longer or shorter than the planned 32inches width of shower?
Finally...After all board is installed...do I use regular mud/tape at that seam between the two materials?

Typically I run my tile just past the seam where the 2 meet. Mark it out on the wall where your tile will end, then run your Kerdi or Kerdi band just short of or to your line so you cover that seam where the transition is.

I do it that way as well, here is a picture.

1/2 kerdi board, kerdi band, painted drywall.

If you are reframing, make sure to place a stud where your Kerdiboard ends and the drywall begins so you have an anchor point for both materials.....

Ok...so I leave a small gap between the kerdi and drywall...tape that joint with kerdi band - not regular tape- then run the tile about 1/2" onto painted drywall...With a stud for each material?

Nice picture Btw.
Thanks

[sycamorebob]

Thanks, no need for a gap....

One stud, both will attach to the same one.

If you're going to have a door hinged on wall, you'll want some meat where the hinges will land. I often frame an ell with one flat 2 x 4 or 6 attached to another at right angle to add bending stiffness.

Also, if you have door installed by glass company, let them know it's Kerdiboard. I've seen damage caused by impact-driver-happy installers assuming that the K-board tile assembly in un-crushable.

I flat framed that stud with another next to it forming the "L" Carbidetooth is describing above. Having a wide area to screw both your Schluter hardware and drywall screws not too close to the drywall edge is definitely a nice to have......

Based on feedback here, I also used alkali resistant mesh tape instead of kerdiband at the kerdiboard/drywall transition. I was far enough away from my wet zone not to use the banding. Used the tape to strengthen the area and prevent grout cracks.....

Not really a tile guy...doing my own bathroom job from framing
So...im planning a 32x72 walkin shower...and I've got a square 3 foot window on the side wall where the 32 inch mark off back wall is. ...just 2 inches away from window well.
So...how much room do you usually allow for a 32x72 shower?
I figure I'm using Kerdi board to come out from back wall 32inches. ...and 8 feet up.
Then just drywall ...green board or regular 1/2"?? ....drywall upto the kerdi edge...mesh kerdi tape that transition and bring tile past that joint ( which is just 2" from window well edge) by another inch....which leaves my tile pretty much right at edge of window..just 1 inch away from window well.

What would you do??

Welcome, Jimmy.

Please keep all your project questions on one thread so folks can see what you're working on and what's been previously asked and answered. We can give it a more generic title any time you'd like to suggest one.

A photo of your situation might be helpful here.

These 2 pics show where the 32 inch mark is off back wall to window.
Just not sure the right way how to finish .

So twice now I've tried to start new thread but somehow ending in here. Doing this off smartphone

And twice I've combined your new thread here, Jimmy. Please see post #11.

I, for one, don't understand the question. You either use your KerdiBoard or drywall in that area depending upon whether it's in the wet area of your shower, which thing I cannot tell.
