Geberit 111.335.00.5 DuoFix In-Wall System with Sigma Concealed Tank for 2x6 Wall Construction, Plastic, White

We recently remodeled our beach house, adding a bedroom and bathroom where there was originally a family room. We were tight on space and not thrilled with the bathroom layout that our architect had initially proposed, specifically the toilet location. I suggested a different layout with an in-wall tank and pocket door, moving the toilet to the side wall just inside the door. This transformed the bathroom and allowed for a much bigger vanity. The traditional toilet now seems archaic to me. The europeans have been using these for a long long time. We are as usual late to the game.My plumber was not familiar with these wall mounted tanks so I installed it myself and he plumbed it. If you are a decent DIY it’s not that difficult, just make sure you frame the wall accordingly to fit the assembly. You can download the specs.I did use a Duravit 2227090092 toilet which I have mixed feelings about. I seems to get black growth under the rim, especially during warmer months. My other conventional toilets don’t have this problem.I am getting ready to do another petite bathroom. I am going to try the version for 2x4 frame construction. The price has increased about 25%, but it’s still cheaper than the other options. The toilet has fallen slightly in price. Don’t forget the trim kit. All in with toilet and trim budget about $700-$750, again comparatively affordable to other wall mount systems. It’s space saving benefits do come at a cost. For me it was well worth it.

I bought the Geberit tank carrier to pair with a Toto bowl. The tank is a a 1.6 gallon and the bowl is rated for 1.28 gallon but they work fine together. I wish the water level in the bowl was higher though.

I was doing a bathroom remodel for a small powder room and started looking at wall-hung toilets because I wanted as much free floor space as possible.I was trying to figure out the difference between all the toilet tanks systems --Toto, Geberit, Duravit Kohler etc. I'd seen this specific tank recommended by Amazon with the Toto toilet I was looking at, and at first I was worried about compatibility issues. In the end, it looks to be cross-compatible with many of the systems I looked at. The main thing you need to figure out is whether your framing uses 2x6 or 2x4 and pick the right tank frame. Go to the Geberit web site and see their list of compatible toilets to be sure.2x6 wall studs: Geberit 111.335.00.5 Concealed Toilet Carrier Frame with UP320 Dual-Flush Tank2x4 wall studs: Geberit 111.728.00.1 Concealed Toilet Carrier Frame with UP720 Dual-Flush TankA lot of people worry about having a toilet tank system in the wall. Given that most of the parts are injection molded, the chances of leaking in these tank systems is low. The parts that you need to access are concealed behind the flush plates, meaning you can access it at any time.This toilet tank does not come with extra parts you need / may want.1) The actual flushing plate. I guess that's to let you pick what style / colour you want. They are quite pricey!2) The acoustic insulation bowl connection set (Geberit 156.050.00.1 Acoustic Insulation Bowl Connection Sets and Accessories). For the fact that it's just some sound-deadening foam, I thought it should have just come with the toilet wall carrier. Since I was in a hurry to install and I didn't have this kit, I just made-do by cutting some packing foam sheets and stuffing that behind the toilet for acoustic insulation. So far it seems to work fine, isn't noisy3) Connecting pipes, etc.I highly recommend watching the Youtube installation videos. They were a great help.If you are looking at these types of toilets you know that they are expensive systems, but within that price range this brand seems to be the best value of the bunch.

I spent hours looking at options for our lake house half bath and am very happy with this toilet. We paired it with a Toto toilet Bowl: Toto® Ep Wall-Hung Elongated Toilet Bowl With Skirted Design And Cefiontect, Cotton White - Ct428fg#01The flushing works great and is powerful and the toilet doesn’t give us any issues with stuff on bowl. We are very happy with the purchase.

So many parts are missing!

The biggest advantage of this type of toilet/tank installation is the saving of space, and that made a nice difference in our small inner bathroom. Our experienced plumber has installed many wall-hung toilets but had never used a Geberit wall tank before. He thought this tank was the "Bugatti" of wall tanks - he really liked the construction and the mechanics.We had an outside wall 2x8 cavity to work with, so there was plenty of space to insulate behind the tank and frame as well as in front of it (frontal insulation not shown in the attached picture). We doubled up the 2x8 studs on the sides to stiffen the install and we couldn't get the frame to deflect an iota. The plumbing was very easy for the plumber to connect.The only caution I can share is that when you are finishing the wall surface, the threaded rods for hanging the toilet extend out from the face of the wall quite a bit and it's easy to catch your leg, arm or head if you aren't careful. Maybe stick a tennis ball on those or have some band-aids ready to go.

Having a lot of problems with the actuator and stuck valve. About 1 flush out of 3 does not reset the pins and toilet runs continuously so water supply has to be shut off. Now, after latest incident, can't reset pins at all. To be honest, I don't think our installer was very proficient at installation and he said that he couldn't ask for replacement parts or assistance because "after all, you bought it on Amazon rather than one of my retailers." I'll provide an update with my experience trying to resolve the problem with Geberit.
