New Schluter Shower Pans (Thinner): Any feedback?

Curious if anyone has any experience with the new Schluter shower pans that are thinner and supposed to make curbless construction easier...

Any issues? Having the ability to use smaller tiles is a plus. Are they stiffer and stronger, less prone to flex?

The fact that these aren't available with the linear drain may eliminate them as an option for me, although I am not 100% certain yet, but interested in the wisdom found here!

It appears the biggest advantage is that the membrane is pre-applied/laminated to the pan. And I'm pretty sure I saw that they are available with a line drain. I didn't look all that closely but didn't read any details about minimum tile size.

Looking through the size table there are only two sizes than come with a perimeter thickness of less than 1". All others are at, or well over, 1". I think it's a little misleading when they say it doesn't need to be set in a mortar bed, it does, just a very thin mortar bed.

Still, the only real advantage I can see over, say, USG's foam pans is the pre bonded membrane which will speed installation time. They still don't offer any custom sized pans like USG does.

I just bought the 76" x 38" (long side drain) size for a barrier free shower I'm putting in an old bathtub alcove. The substrate is a little over 3/4" thick on the drain end and 1 5/8" on the thick end. I purchased a 140mm drain and it all looks straight forward to install.

I lowered the floor in the alcove by 3/4 " by recessing the subfloor flush into the joists. I do not want to cut the joists because they already have a long span for their size.

I do have a question.

I was going down the path of placing the drain on the entrance side of the alcove and pitching up towards the back of the shower. Ditra heat on the floor and going a little heavy on the thinset under the pan gets me pretty much lined up at the drain and at the hardwood transition in the hall.

A tile guy mentioned that I'd be better off with the drain towards the wall but that means another 5/8 layer of plywood in the room and a 5/8 transition at the hallway door so it kind of defeats the curbless idea a bit.

Do you think the placement of the drain matters that much? The drain will span the entire opening except for maybe 1-2" on each end depending on wall tile thickness.

Interesting...it's taken nearly 4-years for them to integrate the waterproofing on all of their trays...they'd talked about it nearly 4-years ago in a class. The linear drain pans have had it for awhile, though. One can say this about Schluter...they are very conservative and really won't introduce a product until they're positive it will work in the market without issues (assuming you follow instructions!).

My research continues and I have another question regarding the linear drain installation. The FAQs state that the drain should be 2 ⅛ on center from the wall. Obviously this measurement needs to include the thickness of the wall, but is this enough room for the linear drain to fit against the wall? Do you allow for any "wiggle" room? I guess it makes sense to have the shower pan and drain here to confirm location?

The room is for the flange of the drain and to help ensure you get the proper overlap to make the seal. I think you'll find that is unfinished wall to unfinished wall, so once tile was installed, it would end up smaller. Double-check to be sure.

@Howarda- you seem to be heading down a similar path as me. I was ready to scrap the barrier free idea, but thought this new tray may make it easier. I too was planning on filling in between joists and bolstering that. It sounds like the thicker side would still require a "shaving" of the joists to have a true barrier free setup and maintain floor level for transitioning to room adjacent to bathroom. Am I understanding that correctly? I was hoping to be at the same level with Ditra or Ditra XL on the floor outside of the shower. The 9/32 of Ditra XL doesn't cut it I may be back to a smaller curb, which is not optimal design-wise, but certainly manageable. Now thinking out loud, is a smaller curb more of "toe stubbing" hazard than a more substantial one?

You could also try a speedbump instead of a toe-stubber. Got this photo off a former JB forumís image.

So maybe I'm just spreading internet rumors but...

I had heard that Schluter came out with new more rigid shower pans that would accept smaller the 2x2 tiles. Maybe these are it? I didn't see anything about minimum tile size.

But I think they are made out of XPS foam as opposed to the others that were EPS which would explain a pan with more density.

But, as I said, maybe these are just rumors.

I think I would need to see the "speed bump" with glass and finished to know if I would like that. I did see the "ramp" from Schluter a couple of years ago...

I may be sorry (we'll see) but I turned the pan around so it's in an entrance drain configuration. My shower is in a three walled alcove and the drain stretches all the way across the opening minus 1 1/2 inches on each side. That only required me to drop the subfloor in the shower alcove into the joists. I was dead set against notching them because they are 2x10s at a 14 feet span.

The line drain lines up perfectly with the ditra heat in the rest of the room.

Big bucks all in though.

One observation is that it takes about three days for the mortar under the Kerdi band to set up. Don't even look at it for 3 days after you waterproof or you'll swear it's all going to fall apart.. I used Kerabond T.

I am waiting for delivery of the new line of pans by schluter. I ordered a few weeks ago and there is a delay until like november 6...
They claim the foam is denser and approved for all sized tiles (mosaics on floor). The membrane is also pre-applied.

I know they did not forbid mosaics on the "old" trays, but recommended 2x2 or larger.
