The saga continues -Bathroom #2 reno starting- what is the process to install a floating toilet and seal or remove the old plumbing ?

[Mini Me]

The main drain and the way other things are connected to it is shown here. I will have hire a plumber for this.
Before I do that I want to educate myself and to understand what would cost to do this and what is the correct order of the steps needed
The bathroom that is downstairs is now finished and I have had no problems with it.

Code compliant solution to relocate my drain&vent near the wall for their basement section?

I have this bathroom in the picture below and I would like the soil drain and the vent to follow the green line in the picture The drain is 19" away from the wall and the vent is 29" away from the wall There was a tiled wall there that I removed the drywall from in order to redo the tiles and I...

It was an extensive reno and I had no idea what I was getting myself into. Thanks again for all the help in the past.
Now I want to do the ground floor bathroom (bungallow with finished basement). While I would do minor plumbing and tiles cabinetry and so on by myself, I think that replacing the toilet in the picture should be given to a plunber. While I asked around here how the floating toilet is installed on the wall I am not clear on what happens with the plumbing for the old one that is in the floor. The main drain is copper pipe and it is 3" diameter. (the vertical purple pipe in the picture) It is also act as a vent for the plubing.
The horizontal purple piles off the main drain are the drains for a bathtub and for the sink on that floor.
Q1: what happens with the old drain for the existing toilet on the upper floor?
Q2: considering that the main drain is on the side of the now floating toilet how is the plumber going to connect it to the main drain? There will be studs to the left and to the right of it ?
Q3. Are they going to cut the main drain and then solder a new T there ?

note: the vertical grey pile you see there is gone, it was a vent for a sink that was there long time ago and removed to generations of owners ago, the pipe was left in the partition wall that I removed

If i am reading this correctly,
you want to replace a floor mounted toilet with a floating wall mount toilet correct??

If this is what you wish to do , you have to be nuts to attempt this.. because of
the difficulty involved in a finished home,,,,,

if this is your plan, may god have mercy on your soul

let me know if I read this correctly and if I did I can go into a
lengthly detail as to what problems you will get yourself into
later on in this thread

Yes you got that right please go ahead

you will literally have to tear up the floor ---either starting over in the crawl space
or breaking up the concrete floor and really go crazy to get that 3 inch drain up in the
wall and somehow cut the 3 inch line and then line it perfectly
up to center where you want the toilet..... this is a project that I will not even
attempt to tackle for anyone

Also, I have walked away from projects where the customer wanted to do the reverse
and get rid of the floating toilets in the walls and replace them with normal floor
mounted ones.... its just too much of a manhood contest to attempt

Another issue is the bracing that has
to be installed in a wall to hold up the toilet..... it sometimes is nearly impossible
to add enough support in a thin 2x4 wall to hold the toilet solid to the wall.....
Yes they make commercial supports that go into walls but they have to be secured to
something really stout

I have seen disasters where the 2x4 metal walls in a ladies restroom could not handle the
strain of the big lard ass ladies slamming down on those toilets month after month and eventually
the stress pulls them loose... The big heffers literally pulled the carriers out of the walls and actually
cracked the tile on the walls....
We had to improvise before where we had to use a white piece of 3 inch
PVC pipe and cut it to the exact length and wedge it under the bowls of the toilets down to the floor to
add support leg to the toilet....


you would be wise to just live with a normal floor mounted and use that energy and money to
spruce up the bathroom in some other way....

remember all this trouble just to sit down and take a crap. on something different.

Anything can be done if you want to spend the money to do it
You can install a toilet up on the roof if you really want to spend the money to do it
and then you can sit up there and read your Sunday morning paper and feel like the king of
your domain if you really want to---- but at what cost???....and why??


fools rush in where wise men fear to tread...

It will be a complete bathroom reno.
The floor is not concrete but wood framing as in any US or canadian bungallow. The foundation is cinder blocks, you have concrete floor in the basement bit the main level sits on wood beams and it is playwood sheets and linoleum currently. I am replacing that with tiles. The wall in question has nothing hung on it on the other side. I could open it and replace the studs with metal studs and add as much support there as needed. Having that said I need to understand what happens with that old toilet drain and if it is difficult and costly to connect in the wall to the 3" pipe. It should be possible as this is a 2x4 wall so it will be 3.5 in nominal inside the wall

Good luck with that is all I can say...... i have never attempted this myself
I only had to make repairs to a few.

the metal studs are really not as stout as 2x4s
you might want to be sure about how deep the wall needs to be to
fit the commercial carrier that goes in the wall....as I have never done one and it might
take more like a 2x6 or 2x 8 wall to get it all to fit ....

Also your biggest issue could be finding a plumber to do the job

abandoning the old 3 inch drain line is no big deal at all... that is the least of
your problems


you be the king of your domain... good luck

It's the vent.

Your old floor mount toilet isn't vented correctly. Your new wall hung toilet drain ties into the main drain under the concrete floor, but it'll need a vent that either ties into your current vent system or all the way out through the roof from the basement.

If he can figure a way to vent the whole bathroom from that vent, that would be optimal.

 

[Mini Me]

main floor (top of the picture) is all wood what concrete are you talking about
the purple 3" is acting as vent for the toilet. It goes up and out through the roof
that should be OK

No the purple isn't a vent it's a drain.

Your drawing lacks detail and isn't correct. The second floor toilet can't drain into the first floor vent. You need a vent that is dry from the first floor toilet up to the second floor.

I remember your posts from your first bathroom. You just argue with everyone instead of trying to make things clear and trying to find a path forward. You need to consult with a local plumber they will have more specific info about what's acceptable locally. Generally your drawing isn't legal.

That is not going to happen.....LOL... this fellow has a throbbing hard-on to do this his way.....LOL


Now... If the purple pipe is the drain and is in 3 inch copper that is ok and will work...
because the downstairs bathroom has a 2 inch re-vented line which is also is the downstairs toilet vent....
My own personal house is plumbed this way with the upstairs toilet passing through the same drain pipe as
the downstairs toilet ..... it just has a revent on it

If he is crazy enough to proceed with this project he will simply have to capp off the branch arm to the second floor toilet
and abandon it.... then he will have to find a plumber hungry enough to get into this project....

and then he might have to widen the back wall to 6 to 12 inches wide to accommodate the toilet carrier.
the odds are 50-50 on this... I dont know what is presently available


I would suggest you do your homework on what vertical wall space you
need for the toilet carrier before jumping head long into this......

oh I take my time to make decisions and to start the project.
the above drawing might or might not be totally correct.
It is representative for the first floor. I think since I posted this back then I have added a few more showing more and more details about the project. I am glad my project was not forgotten. Sorry to disappoint that 4Y later everything is OK.
