Help with wall mounted toilet install question

9 years ago

I am considering a wall mounted toilet for my small powder room. I realize that we will have to tear open the wall, possibily build it out to get the space we need, reroute the drain, and repair the hold in the foor where the existing drain is.

My guestion has to do with the installation of flush plate, and neither the Toto or the Geberit tank install instructions seem to address this in much detail. I know I have seem pics on Houzz where the flush plate was mounted horizontally on top of a ledge behind the toilet, and not vertically on the wall above the toilet. Is this an option with all tank units - can it be done that way?

I'm trying to figure out how much flexibility I have to determine the location of the flush plate - I don't want iot horizontal but I want it on a different vertical plane from tje toilet. I want to bump out the bottom of the wall and have the plate on the original wall above the bump out.

If anyone here has experience with these things, can you please comment? Thanks.

Same comment as before and still no numerical reference nor existing plumbing layout.

snoonyb, not sure why my question depends on the existing plumbing layout. We have already determined that we can move the drain and water lines to accomodate the inwall tank. My question just has to do with the location of the flush control relative to the inwall tank unit. Am I missing something?

I looked again at the Houzz pics and it occured to me that some of the layouts I am seeing on Houzz where the control is not on the wall directly above the toilet may be from Europe, and they may have additional product options there that we do not have in the US.

It also occured to me that if the flush control panel is not right on the front of the tank unit, you would lose the ability to access the unit for repairs. So even if it might be possible to move the location of the control, its probably not a good idea. For that reason, I plan to stick with the normal configuration even though it requires me to tweak my design.

In all my research of toilets, I found no other such toilets. I purchased a neorest and a hatbox. I have heard nothing about the hatbox and have actually never used one. I purchased it mainly for aesthetics and size. I have friends with the neorest and they have had no problems. I am a little concerned about the kohler hatbox from my past negative experience with kohler's silent flush models, but I do understand I should not compare "apples to oranges" Since I am/was doing a major remodel with new walls, I thought of installing a tankless toilet. However, I decided that they would be too complicated for the typical plumber to repair and I also kept running into obstacles when I attempted to order the carriers. Also, I plan to rent out this house in the future and figured the carrier in the wall might cause problems that a tenant might not notice until it was too late. Kelley

I was hoping you wouldn't say that because I wanted to do this in stages: replace toilet (it leaks) and vanity (it's hideous) now, then deal with tile in shower and elsewhere on wall later (no one uses the shower right now). Grrrr. And I am going to replace the floor. I've already heard that the current floor tile must be removed before replacing toilet, so that will be my next DIY job.

I have a Toto Maris ready to install. But I bought the Geberit in wall tank rather than the Toto tank - reason being, the Toto tank requires an adapter for a 2 x 4 wall and I understand the adapter reduces the drain size, but Geberit accepts a 2 x 4 with no reduction in drain size. also, Geberit has been around forever, and the in wall tank from Toto is a new product. FYI, I got everything, including a very nice metal (not plastic) flush button unit, from Amazon. Can't wait to get mine installed - we bought ours because of space concerns in our powder room, but also planning to use one in our master bath remodel for ease of cleaning as you mentioned. Here is a link that might be useful: Toilet Actuator Rough-In and Trim Set - Amazon

" not sure why my question depends on the existing plumbing layout"

Because, unless you are contemplating a total reconfiguration of the waste and vent lines affected, which you have not stated, and think that any contributor has been to your house, unbeknownst to you, you are asking for our best imagination, on the unknown.

Again;"still no numerical reference nor existing plumbing layout."

And if there are any opinions from local plumbers, what were they?

Now that our installation is complete, i thought I'd answer my own question in case anyone else is interested. We used the Geberit Sigma tank designed for 2 x 4 installations. We wanted to go straight down, not the angled option it allows which they indicate does require more depth. But even the straight down option still did not quite work in a 2 x 4 framed wall and we had to shim out the wall a little bit. Not a big deal for us, but just a heads up.

In addition, Geberit has a Sigma tank for 2 x 6 walls and an Omega tank for 2 x 6 walls that is designed for half walls and so the frame is not as high. The Omega tank does allow for the flush plate to be mounted either on the front wall or on top of the wall - the Sigma models do not have that option. I am looking at the Omega option for my next bathroom remodel because I want a ledge behind the toilet and don't want the ledge too high. I do note however, that the access area (through the flush plate opening) is smaller than on the other tanks. Not sure if this will be a big deal or not and if anyone has any experience with the Omega model please comment.

By the way, we love our wall mounted toilet. Definitely more expensive and difficult to install, but worth it IMO.
