 New Bathroom, Need Help!
Author: briarb19 (PA)

Hi All,

First, I apologize but I have very little knowledge when it comes to plumbing. I'm in the middle of attempting to convert a half bath to a full bath with a stand-up shower. We are having issues with the toilet, or really the whole layout. Originally, we wanted to just rotate the toilet to face the door, place the shower in corner adjacent to it, and then move the sink near the door to the right after you enter (see pics below). However, a plumber said the toilet can't be rotated without destroying the joist, and moving the toilet isn't possible without creating a significant drop in the finished basement. I'd really appreciate it if someone could take a look and offer any solutions or suggestions for a different layout. Maybe something outside the box, like a different kind of toilet or another way of plumbing?

If you fur out that wall behind where you want to move the toilet, that'll prevent any damage to the floor joist.

I need some education on this, the toilet flange is circular, why can't the toilet be rotated 90 degrees clockwise so its back is against the north wall in drawing, without affecting the floor joists?

It can be rotated but just as was suggested you need to fir out the wall behind the new toilet location and extend the closet bend so that it is not 12" from the wall but at least 16". You will fir the wall out so the closet ring will be 13" from the rough framed wall. Of course you will need to move the water so it is behind the new location for the toilet, normally 6" from the floor and 6" to the left of center of the new toilet location.

Thanks for the replies! Can you explain the process to "fur" out the wall behind the toilet? By the way, that is the side of the house, not another room, so there is likely bricks or concrete behind the 2x4 framing.

What you do is add more wood framing to the existing 2" x 4" wall. Depending on the distance from the wall to the joist now you might end up with a 2" X 6" wall or even a 2" X 8" wall. That will allow the toilet's tank to sit right up against the drywall, will give you a higher R-value insulation, and will prevent having to notch the joist. The only place furring would be needed is that 3' or 4' section behind the proposed toilet location. It wouldn't need to be the entire width of the bathroom.

 Awesome, thank you so much for the explanation :clap:

Awesome, thank you so much for the explanation. Could you explain why it is needed? And perhaps, why the other plumber said we would have to notch the joist? I was also told a minimum of 30" space is needed. Is that true?

I got the idea that if you left the wall as it is the toilet flange would have to be moved closer to the wall so the toilet would sit properly with its tank near the wall. Moving the toilet flange in that direction would mean cutting into the floor joist. Notching or cutting the floor joist to make room for the toilet drain would weaken the joist and you could get floor sagging or squeaks when walking in that area. There might be a way to notch the floor joist and then reinforce the bottom half of the joist by sistering on each side of the joist. If so you could leave the wall as it is and move the toilet flange to where it needs to be. Not sure that would work since the weight of the toilet plus a person would be bearing down on the joist.

If you sit the toilet on the flange where it is then the flange can be left as-is but the wall behind it would need to be built out so it would be closer to the back of the toilet. But your drawing didn't have any measurements so I'm not sure how much build-out would be needed. In one of your photos it kinda looks as if the toilet flange is the same distance from the west wall as it is to the north wall (directions oriented from the drawing)??

But, it would look "dumb" if it were just behind the toilet and not the entire wall. Extend the closet bend 15" from what will be the new side wall and install a 14" toilet without "furring' out the back wall.

the wall is less than 3 feet long.
