Shower drain

[frank19991999]

Hi All,

I am replacing a bathtub with a shower. The drain is 1 1/2 all the way to the main horizontal stack. Please take a look at the attaached picture and let me know if my plan is OK ? Is the toilet flange to close to the new wye ? The distance is about 11".

Thanks much

Code nearly everywhere requires 2" for a shower; 1.5" is fine for a tub.

Thanks for your reply and sorry for the confusion - I was in a hurry and didn't explain enough what I need -

I rented a demo hammer and dug all the way to the main stack. I need to replace the existing 1 1/2" drain with 2". I thought I will find a 2" pipe somewhere to attach the new shower drain but no luck. My plan is to cut that 3" pipe and insert a 3x3x2 wye and go from there.
Is any minimum required distance from the toilet flange to the wye ?

Thanks

you can put it as close to the toilet vent as you like. Make sure you vent the shower(11/2).

Thanks much for the answers.

Is using a 11/2 to 2" coupling to connect the new 2" pipe to the existing 3x3x11/2 wye an option ?

Thanks,
Frank
