Hi, I'm converting my tub shower to a walkin shower. I have my pipe laid out and was just wondering if this is an ok setup or if something needs to change. I would really appreciate feed back because I would like to fix any mistake that I may have. I tried to take good picture of each side but if you need more information I'd be happy to provide it

You’ve created an STrap. That’s wrong, needs to be corrected.
It wasn’t like that before......what did you do ? Did they cheat and put the vent pipe under the tub then 45 back into the wall ?
A shower doesn’t offer this dead space to hide a pipe and now for a shower it’s in the way ?

Take a pic of what it looks like now standing back a little so it includes the whole area.
Delete the piping in red.
Cut in a wye fitting where the yellow is and let it point toward where you want the p trap located.

Like this. You can use whatever fittings you need out of the wye so you can position the trap properly.
If you cut in the wye in the proper location you may not need any fittings to align the trap in the proper location. Otherwise you may need. 22.5 or a 45 to put the trap in the proper location. The goal is to cut the wye in so the p trap can swing to it’s proper location.

All you’re doing is relocating this basic piping that you already had, minus the portion that connected to the tub(waste and overflow)
See how the trap connects to the wye fitting and the wye fitting continues and turns up into the wall for the vent.
It must connect to the vent before you make the turn to go down into the wall with the drain.

Alright cool thank you so much! I'll get some more material tomorrow and put it together and send another picture so you can see if it is all good to go. Does the wye have to be up a certain amount on the pipe shaded yellow? Then lastly if my drain is 2 inch pipe and the shaded yellow vent pipe is 1.5 inch is that still fine also?
The wye needs to be 2”. You can reduce the vent portion to 1.5” but the trap, wye and the drain going down the wall needs to be 2”.Ok so I know that the pipe for walkin showers needs to be 2 inch all the way to the next larger pipe meet up. I'm still needing to switch out the existing 1.5 inch line that runs down to the base with a 2 inch line. But this is where the existing line meets up with the 3 inch pipe in the basement. So I'm just trying to figure out the best way to connect a new 2 inch line to the 3 inch line. Do you have any ideas

I got the new lay out in place I haven't connected the vent tube yet but you can still get an idea of what it would look like. So if this is looking better then the next thing would be the best way to connect a 2 inch pipe to the 3 inch pipe in the basement, I left a picture in the previous message if you haven't seen it yet.

Sadly you have to cut a 3x3x2 wye into the 3"pipe. Cap the 1.5"pipe.

I'm pretty sure that fitting isn't legal to drain like that either.
If that's the vent for the toilet then his vent piping should be 2"the whole way also, but who knows if that's possible at this point.

Ok so couple things now.
1. I'm guess the new layout that I have for the drain is good since you didn't say anything about it?
2. The 3 inch pipe is pretty stiff since its connected to more pipe shortly after that 1.5inch connects to the elbow. So is the best way to add a wye joint to be to remove the toilet so that one side has some wiggle room.
3. Where the 1.5 meets the 3 inch if I try to remove the elbow will the whole piece actually come out so that I can put a cap in it, or is there a possiblity that it will break and the glued piece will stay inside the 3 inch elbow. Or what's your advice for removing the 1.5 elbow?

1. The shower piping looks good.
2. Can you cut in the wye downstream of my red mark ???? If there’s more room downstream it would be fine.
3. It would probably break. Just cut it off and cap it.
I don’t believe they were using the 1.5 connected under the toilet as a vent now that I see all of the piping. It was acting as a wet vent but I doubt that was their intention.
Ok couple more far away picture the first one I was just identifying where each pipe was going so the blue pipe does go to the first level toilet, the green goes to the upstairs toilet, and the orange should be going to my laundry room for my washer. The other two pictures I just circle where I was thinking about putting the wye joint and am curious if this position for it would be acceptable?

That’s exactly what I’d do.
Perfect, when I get all of that laid out I'll send a couple pictures and see if I need to change anything.
