I have a full bath and a half bath that is back to back. I want to add a shower to the half bath. I have a closet where the new shower will be.
this room sits directly behind the main bathroom . the toilet and sink are back to back, the bath tub in the main bath is back to back with the closet., I have access to the plumbing for the bath tub from the closet area,, I am
pretty clear on what will have to be done. my main question is where to work the floor drain and where I need to cut the slab to so I can attach to a suitable drain. the toilet sits next to the closet opening I can see the
main stack pipe from the access point in the closet.

If your shower is going to be directly behind the tub I can see a couple of maybe problems. First if you plan to use the tub drain for the shower it is too small. A tub drain is 1 1/2" and a shower drain needs to be 2".

The other problem I see is if that wall is tiled how will you get in to take care of the tub if it leaks?

 

[misterd0]

few possible problem are welcome big jim

The problem you mention is valid, but nothing I can't work around. My primary concern is to get the floor drain work around fixed. the rest I will be able to deal with.

Thanks

Ps. I hav'ent decided about the tub drain that's one of the reasons I'm looking for advice.

I wish I knew an easy fix for that but I don't. One of the fellows who is really up on this type thing will help you, I am sure.

You'll need to be sure were you are going to tap into is the system PVC or Cast iron? pvc much easier cast iron you may have a problem finding space between the hubs back to back combinations have multiple fitting usually with very little spaces of clean pipe to splice in to. you may have to go down stream of the toilets. you can not connect to a waste arm tub toilet etc. you may have to re vent it ????get a camera with a locator trace the pipe and combinations.

 

[joecaption]

Anyone notice those copper lines where not sleaved to keep them away from the slab?
How to you plan on busting out the concrete and redoing the drain with the tub in the way?
Another issue is if you did it that way you would have to bust out the wall in the tub area if someone wanted to replace the tub deverter.

Way off base major code violations and tons of problems in the future, will not work what you think is below the ground is not. i was called out to a job last year were they had a shower clog, they called roto rooter the guy went out and put a half inch cable through the shower drain it jumped over in to the next bathroom came up the over flow broke the plate and grabbed a bath towel that was in the shower on a towel bar. the idiot got stuck the homeowner told us he was there for 3 hours trying to get the cable back when he couldn't he cut the cable and left when the owner went in to the other bath they discovered their bath had been torn up by the slapping cable, to the point when we broke out the floor to repair the pipe we found something similar to what you just drew, turns out the lady had a shower installed exactly what you want to do the plumbers she called were to expensive so she called a local handyman that gave her a price she liked. well insurance didn't cover it because she used an unlicensed contractor, cost her double to correct the installation. i cant get my scanner to work if not i would draw you what you most probably have in the ground and how and were you need to connect. maybe someone one the site may draw it out for you so you can get a better idea.

I knew if I stayed away from this one- some one would put my thoughts to words.....

thanks for the reply, however, if you don't point out the violations and issues that's in the diagram there is no increase in knowledge on my part.

thanks again

i was called out to a job last year were they had a shower clog, they called roto rooter the guy went out and put a half inch cable through the shower drain it jumped over in to the next bathroom came up the over flow broke the plate and grabbed a bath towel that was in the shower on a towel bar. the idiot got stuck the homeowner told us he was there for 3 hours trying to get the cable back when he couldn't he cut the cable and left when the owner went in to the other bath they discovered their bath had been torn up by the slapping cable,

I would say this is too crazy if this didn't happen to me. When I was still an apartment dweller, the next apt was being snaked. The snake busted through the side of the toilet in our bathroom and came out and grabbed the shower curtain. It was dark back by the bathroom and all of a sudden there is major commotion going on in there. Scared the crap out of me.

Sorry, just a story to tell.

On the drawing you got a running trap on a tub. Then a trap 2"on the shower you can't double trap a fixture. The running trap will make it a double trap. You will need a vent on the shower. Should be one there for the tub now? Hard to believe there is a running trap on the tub now. I think you mite be over your head get a plumber to draw it and have him do the work and get a permits. May you could demo to save money.

Thanks for the reply, I'm always trying to learn something new, As for me being over my head I don't think you know enough about my abilities to say that. If I was trying to complete a project without the proper reseach then I would agree with you. I'm not a plumber that why I am doing the reseach. I was under the impression that this is DIY site.

Anyway thanks for you input.

adding a new fixture to an existing sanitary branch if you don't know codes or drain branching i think your just bit in over your head, i have inspected jobs for plumbers that sometimes still cant get it right, get some professional help on this one you'll be glade later research wont get you anywhere if you don't know what in the ground.

The main vent pipe is id in the third pic by a tape measure and a clothes
hanger stuck in the wall, so I assume what I think is a 4" cast iron connects to the main line somewhere below that. The tub drain directly
off the tub is 1.5 I think it drops into a 2".

Thanks
