Wall Mount Toilet

I am in the process of remodeling an attic and adding 2 bedrooms and a bathroom. I am interested in adding a wall mount toilet and specifically looking at a Toto model. I don't see many mentions about wall mount systems. What are your favorite and easy to install in the wall valves.

I know I will need to build a cavity with 6" studs and 19 3/4" wide, are there any other considerations??

Why so we not see more of these installed residentially??

Thanks

They are more expense, and more work then a standard floor mount toilet.
However, I grew up in a home with wall mount toilets, and it was nice.

The Toto dual flush bowl uses the Gerberit wall unit.
You can also use several othe brands of bowls with the Gerberit.

Thanks for replying so quick.

I was surprised that the prices I have gotten so far for the toto wall mount and Gerberit wall unit didn't seem out of line.

My plumber has never installed one before, should I be afraid?? I am an avid DIYer and have installed plenty of toilets, the instructions didn't seem very difficult. I figured I could make sure he is doing it right.

I have travelled extensively through Europe and almost never see a floor mount toilet being used.

They aren't that hard to install. It's just a matter of having the instructions ahead of time.

With the Duravit Stark3 bowl.

Terry,
TOTO's website implies they'll have their own in-wall tank system 3Q. Any news on that? I'd like to get the dimensions required.
thanks, KLM

Actually I am in the middle of deciding which bowl to choose as well. I am opting for the Gerberit carrier as they have been around for a while and proven to work just fine.
Choice now is between the very similar looking Duravit Stark3 and Toto Aquia. I have seen the Stark3 in a showroom but can't find one with an Aquia one (and according to the Toto sales rep there is none in BC, Canada or WA).
Really liked the Stark3 but cons are bowl is a little more expensive, seats are very expensive... Liked the concealed fastening for the Stark3 that's now available in Europe (unfortunately not yet in North America) but can't wait till it might get introduced here...

Anyone have any good/bad experiences with either one?

Terry, I know you are a big fan of Toto. Just wondering if the flushing on wall hung Aquia would be same quality as 2-piece Aquia II/III, any idea?

Installation really isn't my area of expertise, but I have seen wall mounted toilets installed with stainless steel studs for extra strength as opposed to traditional wooden ones. You definitely need to consider how much weight might be placed on that toilet, especially if you plan on selling your house within the next few years.

Steel studs, traditionally, are NOT as sturdy as wood studs, regardless of which steel they are. The key to any wall mounted toilet is that the "carrier" MUST be rigidly fastened to studs that cannot bend, sway, or twist.
