I have just had plumbing done to add a new 1/2 bath (on a slab). I never thought about where the drain for the toilet was located. I just told the plumber where I wanted the toilet and vanity located against the existing wall . Today they installed the toilet and the tank sits 7" from the wall! The room is small enough as is, not to have the toilet almost in the middle of the floor! HELP! Should the slab be torn up and plumbing redone or is there a better fix?

Hi Elesig...

What is the distance from the finished wall to the center of the toilet pipe?

It is about 20"

I think you need to call the plumber back and ask what the heck he was thinking. The floor now needs to come up again.

I don't want to sound slow.
But in other words tear up the slab-redo the plumbing-repour the slab-reinstall the toilet.
"VIOLA" it's Done? :))

Like Ballenger said, you'll need to rip this up and at a minimum extend the toilet pipe so it ens up at 13.5" to 14" off the finish wall. 12" rough in would be best for space!

Basically, as you asked, tear it up, EXTEND the pipe, patch with a quick patch concrete and then retile/grout... YUP!

MARK

My suggestion would be to look into the drain pipe the commode sits on and see if the pipe goes straight back towards the wall that you want the commode to fit against. If it does I would break out the concrete from the pipe in the floor towards the wall. I would only break it about six inches wide. That way when you repair the concrete all of the repair will be under the commode and should never be noticed if the floor covering is installed right.

After you get the concrete broken out use a new three or four inch elbow, which ever matches the pipe you are using. Hold it in a position that is twelve inches from the finished wall, now mark the pipe that is coming out from the wall at a point where the new ell would slip up on. Now that you have it marked double check everything, even holding the ell on the pipe in the ground and see if it will end up twelve inches to the center of the ell.

Now you can cut the underground pipe, clean it real well, use a sand cloth and a primer on the pipe and the ell and slip the ell in place making sure it will be vertical with a pipe coming up out of it. Now measure the pipe needed to come up to floor level with the flange on the top of it. Put everything together to double check and if it is right then you can glue it in place, making sure the flange is turned so that the bolt holes will be in the right place.

Replace the concrete with some sackcrete and smooth making sure that non is about floor level. After it is completely set and dry you can always make the floor smooth with a floor patch.

Good luck, I told you all of this in case you can not get the plumber to remedy his mistake.

This 1/2 bath is an extension from my original home (slab), directly located on the opposite (exterior)wall of my master bath. So the wall of the bath was the focal point for placement of any kind. I wanted it there so the plumbing would be easy. The drain for the toilet drops straight down 1'1/2 - 2' then off to the right to connect into the original drain for the master toilet. Where you say "extend" the pipe-do you really mean shorten the extension from the original exterior wall?
I am far from any kind of plumber (other than drain cleaner and plunger) so termalogy on my end is confused.

They installed that toilet today so you should not have to do anything other than tell the plumber to correct the problem. I do not know one plumber who would rough in a pipe 20" from the wall, 11-12 is the norm. he made a bug mistake and he needs to bite this bullet.

Thanks for your assistance. I kind of figured what the solution would be, but I needed to hear it from a plumber for support. Thanks Again

elesig,
This repair should be done at the plumbers expense. You shouldn't be out a dime. His mistake--his expense! Good luck, Tom

20" - that's a major mistake. I have stupid question - but have to ask it : Are you sure it is not 20" from the side wall ?

Not a stupid question Milo. That's what we call, "thinking outside the box."
Good catch! Tom

No, there was no way they could have put it 20" from side wall. because there was only one wall and that was the exterior wall of the house that wall was the focal point of all new additions.
\\\\ I added a "sun room and powder room" all new construction. The rest of the walls were built around the existing house!

Should the slab be torn up and plumbing redone

You betcha!
And it should be done at the contractors expense. Good luck, Tom

Thanks Guys for all of yor help. The problem is being corrected (not my dime). The plumber blames the contractor said that is where he was told to put it. The contractor blames the plumber says he should know better. No one is ever at fault but things still go wrong! Go figure

Plumber is at fault. Even when GC tells him to put in in wrong location - he should have caught it and correct him on his call. Plumber is the one responsible for his owen installation, not GC. That's why He is redoing it - not the GC.
