Hi Gary, I’ve been reading this thread and have found great relief knowing that I am not the only one perplexed with this situation. 2. Do you know anything about the Gerberit toilet bowls? It seems that you installed yours lower than his, although your Geberit tank is the standard 2×6 model. It is not lost on me that you have caulked around the toilet in your instructions, so I really appreciate your input. After the toilet bowl is securely mounted to the wall, caulk the interface between the bowl and wall with silicone or elastomeric sealant (Lexel). I tend to use the lower flush most of the time. I tried to keep my bathroom temperature normal, and make sure there is no sudden increase in temperature. I haven’t decided yet whether to go with 2×4 or 2×6 but your information will certainly help me make that decision. I’m kind of scare of family members cracking a wall-hung so i’m looking at something that will rest on the floor; I have pretty heavy family members that quite often visit my house. I haven’t received my Geberit carrier yet but I’d like to start my framing. First, install the actuator cam lever unit by snapping it into the access base edge lip and resting it on molded ridges on tank. Likewise a lower profile seat may help a bit. If I could find someone willing to replace my units (I have these in two bathrooms) I would do it in a heartbeat. When framing this cavity, I used double studs reinforced with Simpson Strong-Tie gusset plates to help meet the load bearing requirements of the unit. My setup is very similar to yours. With our cabin bathroom remodel, we were looking for ways to improve the usability of the small 8′ x 5′ bathroom and decided moving the toilet off the floor and on the wall would open the room and save valuable floor space. Thanks for the kind words. Another option, but likely expensive, would be to convert to an on-the-wall carrier/tank system that would cover the old actuator cutout and allow height adjustments like the Geberit Monolith system wall mount toilet system. Can the rear (discharge) elbow be turned to a slight angle, or does it have to go straight down? We have a wall mounted toilet with in-wall tank. Thank you, really, for taking the time to put this together. If using an elastomeric sealant (like Lexel), working very quickly to smooth, as this product sets up very quickly and has a very short working time before the surface becomes tacky and difficult to smooth. Begin by connecting the supplied 90-degree outlet pipe fitting (black in color) to the carrier frame using the supplied, two-piece clamp bracket.

From my reading and experience, it is a bad idea to run plumbing and mount fixtures in exterior walls. At first I was disappointed that I couldn’t have the Geberit, now we are thrilled. Almost any problem that you could have from not using the carrier would be a total mess and likely end up costing you much more in the long run. The carriers are support frames that install inside of a wall to provide reinforcement so that wall-hung toilets can bear the weight of users. If you have the option of using a 2 x 6 wall, its probably better – stronger and more room for plumbing. And, if you factor in the tank I strongly believe it is a no brainer to use a carrier. To check the depth of your wall cavity, I would either open a fixture cover or electrical box (turn off the power) if I thought it would allow me access to the wall cavity or drill a very small hole in a hidden spot and pass a wire to determine the depth.
