Wall Hungs - Do they all Sag

[Chefwong]

The plan for the next renovation is a wall hung toilet. Been paying attention whenever I see one - as someone old me they all sag over time. Any pros or joes on board that can confirm ?

If it sags, it is because the carrier is NOT secured/braced properly.

Have not dialed in all the specs, but I was leaning on the Geberit carrier.

The comment on sagging, I dunno if it's more the carrier or the sagging from the mount rods off the carrier where the wall hungs mount on.
I have zero experience on wall hungs . Aka, do the rods fatigue over time

Wall hung toilets shouldn't sag. If they do its because they aren't installed correctly or there is not the proper backing behind the wall.

We just replaced 2 on a project where the toilet was just a schoche shorter than the back of the carrier and it crushed through the tile. We replaced both with a slightly bigger toilet where the bottom of the toilet rests against the tile which rests against the carrier.

Its important that the carrier be 100% flush with the rough wall so that the drywall/tile backer makes full contact so that the toilet has no room to move inwards. Selecting the correct carrier with the legs that infill that space near the drain is key.

The two main reasons a wall hung toilet sags is because the wall behind the toilet is a plumbing chase and the bolts have to extend a long way to attach to the toilet causing them to bend and obese people.

That is referring to the old style 4 bolt carrier style wall hung? I'm pretty certain the OP is talking about the in wall tank style wall hung toilet which are rated to 600 or 800 pounds capacity with the carrier bolts have about an inch or two of length from the carrier to the finish nut.

Are you sure?

Sure about what? that the OP is asking about 2 bolt carriers?

Yes.

Sure about the bolts only protruding 1-2 inches from the frame through the bowl.. well maybe about 3 inches. But nothing like the 24" long bolts I've seen 4 bolt toilets attached to without moving for 50yrs.

Ok, then it's just fat people.

Heres a pic I made that shows some examples of different style wall carriers. The ones with more steel bars directly behind the drain will prevent that toilets leverage from sagging. When we first started using these we used to install brackets in that area to prevent the sagging.

improperly built . otherwise sagging not a problem

A very heavy person that falls onto the toilet will put a huge stress on things...the weight limits are for a static load (I think), not one that maybe fell from a couple of feet up because they have no leg strength. Under those circumstances, a floor mounted toilet is probably more reliable.

Sag is an imprecise word.
I see movement on ALL two bolt WCs if I sit on one to inspect, facing the wall. And I only weigh 135 lbs, and I have checked over sixty I would guess.

This may be a completely uninformed question but does it need to be installed against tile or is drywall fine? We weren't planning on tiling all the walls.

Either is fine So long as the finished wall has something solid behind it.. Most carriers have metal framing behind the area that the toilet rests to prevent the finished wall from being damaged. But there can be certain toilet / carrier combinations that miss and the toilet will crush thru the drywall.

We would install wood blocking at the base of the carrier to prevent wall crushing before they redesigned the carriers.
