No, I've not used it. The 4" wall space unit trades width for depth. ie - the distance between studs needs to be ~ 23".

I personally prefer closer stud spacing.

You should check the depth of the wall behind your existing toilet. There probably will be a 3" vent stack inside. If that is the case, you could actually have enough space for a 6" depth wall carrier system.

Thank you for the reply. The toilet is being relocated to a 4inch wall. The 23" width can be accommodated much more easily than rebuilding to a 6inch depth. This a very tight fitting bathroom and the wall hung toilet will help it look a little bigger than it is by saving about 7 inches in depth. (floor toilet 29inch vs wall hung 22inch). Needless to say I'm going for it - someone has to be first.

I have yet to use this new Geberit wall carrier (to fit in 2" x 4" wall),however,I have been hearing good things about these. It sure helps open the doors for using wall-hung toilets in more remodels and installations where wall dimensions have normally not allowed.

From what I understand, Geberit has been receiving good feedback with this new design and I also noticed that these carriers work with more toilet models than previous designs.

It is nice to see that someone finally listened for the needs of a wall carrier that utilizes the normal framing of a 2"x 4"wall. This clearly will open the designs of many bathrooms.

I have been checking pricing with sellers such as irawoods.com,hometodreamhome.com, Amazon, eBay, Faucetdepot.com and others. I have found that hometodreamhome.com is the best buy and appear to keep good stock. Irawoods usually has some in stock, but tends to be a little more pricey.

I will keep digging for information on how the new Geberit 2" x 4" wall carriers are performing. If anyone hears anything, please report back as I would like to know myself.

If in doubt, hang it on the wall!

I just wanted to see how it went so far with your 2 x 4 wall carrier. I have been curious to how these take to the market and if they are the best thing since Dorito's chips.

Construction my little project starts next week. I'll let you know. My parents have had a Geberit 6 inch carrier and duravit toilet for 2 years now and think all new construction should have this. I'm being independent and am trying the Toto Aquia bowl. Will post the results in a couple of weeks and let you know if Dorito's take a back seat.

Final Assessment: Great
Have been using this system for a couple of months now & have had no issues. There were no hang ups during installation and we didn't have to build out the wall. We actually chose an inexpensive wall hung Duravit toilet (square d) instead of the toto model since it was more comfortable. A tie with Doritos.

Catherine;

Can you comment on flushing noise level on the other side of the wall? I'm wondering if the vibration of the flush transmits through the framing and drywall to the room next door.

Thanks,

Bill

In my walls you can hear water running, but it doesn't make that toilet "whoosh" or "ker -floop" sound. Not loud at all. Wouldn't wake me up.

Catherine, I am not familiar with these wall hung units. If you have a problem with inner workings, how do you gain access to the wall unit?

You gain access behind the wall plate to any moving parts etc. For installation, I showed my contractor a very good you tube video & I'm sure that there are others for repair. I posted finished bathroom photos and the last message I did gave a link to our construction photos website. So far haven't had a failure, so I can't tell you if it was a problem to fix.

It is unlikely for the inside parts to fail quickly.

Geberit has a larger access panel opening than Grohe.

Even so, I had no issues setting up the flushing mechanism of the Grohe so I went with Grohe.

The only minor downsides are
1. You cannot buy spare parts at the local home center
2. Reasonable care has to be taken when driving nails/ screws to avoid puncturing the tank.

If you replace a regular toilet with a wall-hung, what do you do about the hole in the floor?

When you install a wall hung toilet you are remodeling in a bigger way than if you just replace a floor-mount toilet bowl.

What to Do about The hole:
- you can remove it. This is work.
- you can use the same drain for the new toilet, if this improves your layout. This is also work. Doing so works well with new venting from above, but it also works unvented, because toilets are designed to be generally unvented. Wallmount toilets and rear mount toilets have the advantage of being able to have their drains be vented before going down under the floor. The Geberit drain can be oriented left or right (sideways) to pick up a vented drain. Or they can be oriented to go straight downhill.
