Macerating toilet info


your plumber should be able to relocated the pipe above the slab and tie it into the main drain. take some measurements and do some sketching on where you want the fixtures. moving things on paper is a lot easier than in real life.

after you break up the concrete go over your sketch with your plumber when they come back over to check out the main drain and get their thoughts on what you want to do.

Try and locate you door so that it does not open directly into your Family Room/Game Room/Man Cave area. Imagine the comments from your buddies every time someone comes out of the bath ...... plus if someone forgets to lock the door, not everyone gets a free peak if someone else opens the door

as I said before and Alan brought up also, you will need a vent for the plumbing fixturers. make sure to ask your plumber on that one

You have two options to deal with the exposed pipe.

#1 Cut the concrete all the way over to the wall and put the whole thing under the slab, and come up in the wall.

#2 Since you say the pipe is 2" away from the concrete wall, you could easily build a wall next to the concrete, and have the piping hidden inside of it.


A floor plan would help.


I should also mention that the toilet flange should be centered at 12" from the FINISHED wall. If the drain pipe that is currently exposed were to be below the slab, I doubt it would cause any kind of obstruction whatsoever.

you'd want to build a wall (at least 1/2" away) next to the foundation wall so that you could have a nicer finish. check this forum, some excellent posts on how to build out a wall next to your foundation wall.

The pipe that runs above the slab runs the length of the whole house. It's about 100 feet long. The basement has no plumbing under the slab other than the old toilet pipe, and where the waste pipe goes into the ground. For my plumber to relocate that pipe into the ground, I'd have to jackhammer the whole 100 feet,

good info on the door. I'll keep that in mind for the vent as well. Thanks for all the help!

If I put the whole thing under the slab then I would just use a floor outlet toilet. As I mentioned in the post above, that horizontal pipe runs about 100 feet long. With it being so close to the foundation I'm hesitant to jackhammer the slab to make enough room to put the pipe underground.

if the toilet has been removed why would you hear water flowing if nothing is connected to it? If this is correct I'd remove it as it sounds like you have ground water infiltration, an opening in the pipe somewhere that allows ground water to enter.

is that your water service in the photo next to the main drain?

its hard to tell from the photo but does the above slab pipe run through the wood wall in the photo? can you drop it under the slab on the other side of the wall (don't know what's on that side)? if that can't be done drop it under the slab as close to corner as you can, don't have to do the whole run if not needed.

just some thoughts ....

From what I can tell, the waste pipe from the old toilet is still connected to the house's main waste pipe. The water I hear is the sewer line I think.

That is the water service in the picture. This is why I think that once the pipe goes into the ground, it goes to the right. If it went straight it would run into the water service.

Here is a picture of the same pipe as it runs along the wall of the basement. I could drop it under the slab on the other side of the wall. I'm hesitant to do this as it would involve jackhammer right next to the foundation wall. I don't want to disturb the footing of the foundation by doing this.

Ok, now we're getting somewhere. The initial picture led me to believe that the pipe disappeared into a plumbing chase for an upper floor or something.

(again, a floor plan on what you intend to do with locations of current piping drawn in would help)


Looks like the only other option you have is to build a wall in front of the pipe in the toilet room.


As for making a connection to the pipe in the slab, you can dig it up and see what's in there, or you can call for a price for someone to run a camera and estimate depth so you know what exactly is below the slab there, and how deep it is.


I still would not go the mascerating toilet route.

I'm ok with building a wall in front of that pipe. Can I go back outlet at that point or do you still not recommend this?

I can get started on a floor plan, my plan is to have the toilet installed next to the wood framed wall in the picture (15 inches of the centre of the toilet) then a 24 inch vanity next to and inline with a toilet.

The sink drain will go down into the waste pipe somewhere as well.

I then planned on having my vent just past the wooden wall. It will go up and left and tie into the stack which is approximately 50 or so feet away.

I hope I'm making sense...

Firstly I'd really like to thank Alan and GBrackins for all the helpful advice and for leading me away from my original idea. I broke up the slab this morning. This is obviously the better way to go and I'm glad I decided to go this way. I'll be plumbing for a normal toilet.

ps, the code minimum is 15" from the wall to the center of the toilet, go at least 18" you'll be happy you did

Macerating toilet info


18 is what I'm planning for. I will definitely post some pictures once done. What's the usual dimension to leave for a toilet? I think I read it's 18 inches from the front of the bowl but I'd like to confirm this. The vanity will now go in front of the toilet and I want to make sure I'm leaving enough room for this to be comfortable. Also. What the standard toilet depth?

This is where I'm at so far. The plumber told me if I can dig a trench under where the pipe is now he can put the rest of it underground. What would be the best tool to use to do this? I need to trench right next to the foundation wall, and also I need to somehow do this while the above ground pipe is still there. I don't want to damage the existing pipe and be without plumbing until Monday!

myself I would leave 36" in front of the toilet if you're installing the vanity there.

here's a link that may be of assistance in sketching up your bath http://starcraftcustombuilders.com/b...sign.rules.htm

toilets are typically made with either 10", 12" or 14" distance from the wall behind the toilet to the toilet flange. You could pick out your toilet that way you'll know how far from the wall to place it.

as far as your trench do it like you did this morning coming as close to the foundation wall as your are comfortable. then I'd use a small sledge hammer and chisel. hard to say since I'm not there. if you dig out under the slab that's not broken it would make it easier to break it (hope that makes sense). you have to do what you are comfortable with.

Hope this helps.
