View Full Version : Schluter Dilex-AHK and Rondec

04-11-2015, 08:46 AM
I am a DIY'er with some tiling experience, although I've never used Schluter products. I have a shower and a tub separated by a stub wall. Standing while facing the shower and tub, the back wall is an outside wall. There is a closet wall to the left (north) of the shower, and a garage wall to the right of the tub. Standard stuff, all 90 degree wall angles. I have a Schluter shower kit for the shower. I plan to tile floor to ceiling with 5/16" thick tiles from just before the shower to around past the tub (the pencil line on the painted sheetrock, a similar line exists on the shower side). My question concerns Schluter profiles. I don't want to use caulk for the inside 90 degree wall transitions or for wall to floor 90 degree transitions. I would like to use Dilex-AHK. I also think that I would like to use Rondec aluminum edge profile for the outside 90 degree turns around the end of the stub wall, since it would probably look strange to have profiles on inside corners and bullnoses on outside corners. So now I'm going down this path of having all transitions profiled. That leads me to the two horizontal 90 degree edges on top of the shower curb and the 90 degree edge at the top of the knee wall skirting the tub in the pic where I would use Rondec. The thing about this that I'm struggling with is on the vertical 90 degree inside corner Dilex-AHK edges of the shower curb and knee wall, how does that transition to the Rondec that runs horizontally at the top? While there are caps for stopping a Dilex-AHK profile, it just doesn't seem like it would look very elegant to have a Rondec profile sitting on top of it?

Welcome, Michael. :)

Some paragraph breaks would make that post a whole lot easier to read.

I don't have any of the end caps or corners on hand for the AHK profiles, but I don't see a good way to make that termination look good in your application. But I can't see it from here, and I've never tried what you're asking about, eh?

The only person who really needs to like the look, though, is Mrs. Michael. She's been consulted?

My opinion; worth price charged.

Sorry for being hard to read, what I wanted to say grew with details as I typed it.

So, for the inside corner vertical seams that don't extend to the top of the tile layout, ie; shower curb and knee wall, you would bite the bullet and caulk instead of using a profile? I am very open to doing this the way a pro would do it instead of my preconceived notion.

Hi Michael, :)

I'm having a little trouble with the question also. Wouldn't your vertical inside corners just stop under your horizontal Rondec trim?

I don't have the pieces in hand, but from images it appears that the cross section of a Dilex-AHK is more area than a Rondec profile in this case will cover. So I'm wondering how this looks. This is probably very simple, I'm just not seeing it.

Well, the Rondec is available with inside corner pieces. Don't know how much they'll cover, though. :)

What is the best selection of profiles for this job that includes a tile topped knee wall and a shower curb? I'm not dead set on anything, just looking for advice. I've looked at so much through Google searches I can't see the forest for the trees.

The only thing that I can think of would be to cope the Rondec into the Dilex and silicone that transition.

I'm not crazy about the tub that you have in there and it having no flange up behind the hardibacker. How are you planning on sealing up that corner?

Is this photo below what you are asking?

Jim, yes the area I am concerned with is included in your drawing, particularly the point where the vertical Dilex meets the horizontal Rondec.

For the tub, the backer board sticks out over it on three sides and I had planned on running the tile beginning ~1/8" above and caulking the seam. I would also caulk the seam on the fourth side between tub and the tile on top of the knee wall. Hadn't thought of using profiles on tile to tub transitions, interesting.

What I'm not crazy about is that you are relying on the caulking to waterproof that seam with no backup plan. It might be a good idea to put some Kerdi on those walls and glue the end down to the tub with Kerdi fix. I know it's just a tub but it concerns me a bit. :)

FYI from Schluter:


What is typically done with this type of connection is there is a small gap left between the DILEX connection and the RONDEC and some grout and placed in between the connection. This will allow the grout to be tapered to adjust between the two differently shaped profiles, covering both of their end cuts. I hope this helps. Please let us know if you have any other questions or concerns!
