    Default Steps to flip up sink's drainage pvc pipe

    Hi,

    I am finishing retiling a small bathroom and starting to plan ahead for the new vanity installation.
    The p-trap overlaps the drawer which I would like to avoid cutting. I am thinking of using an s-trap instead a little higher to avoid having to cut the drawer.

    What would be the easiest way to flip the pvc drainage pipe in the pic below 180 degrees so that it faces up and so that I can connect the s-trap to it? Does it look like I have enough pipe there to simply cut it and connect another extender to it?

    Also, I haven't secured the baseboard with thinset yet. What is the most elegant way to make room for the toilet pipe "protector" (not sure what the actual term is). before hand it was simply resting against the old tile with space between it and the wall. Ideally the pipe would have been moved up more. Any other options? Does it make sense to make a round cut in the baseboard to make room for it?

    Thanks as always!

    If you install an S trap, you might as well not have one.
    The p-trap will siphon itself dry and smells from the sewer will be in your home.
    You will have defeated the purpose of having a trap.

    A better solution may be to cut the wall and move the tee in the wall higher.
    Or cut the drawer.

    On the shutoff near the floor. You can either cut the tile, or cut the escutheon.
    It's just a looks thing, no real reason to have one except for looks. We sometimes have to remove them anyway.

    I am a few inches short from the centerline of the sink's drain to the p-trap. I just saw that using a flexible hose is a no-no as well. Going back to the first pic, where should I cut to connect a new longer pipe to reach the drain?

    You may want to cut behind the fitting, remove the esctucheon at the wall and glue on a proper trap adapter.






    Hub goes over the pipe, Spigot goes inside hub fitting

    As usual, that makes so much sense, this way if I ever switch the vanity again, or another owner, can just connect a new p-trap.
    Are the measurements of the pipe odd? I got 1"-5/8 inside and an outside diameter of 1"-7/8. Is something like that suppose to just fit over it (plus the primer and pvc glue)?

    I would think that the pipe coming from the wall is a 1-1/2" PVC pipe. That would be the inside dimension.

    I was paranoid for no reason. it looks like everything will work just fine with a 1-1/2" pipes and adapters (I didn't weld yet). I used:
    - 1-1/2" PVC threaded adapter to the wall's pipe
    - Standard 1-1/2" p-trap
    - 12" tailpiece extension
    - The drain's metal pipe was 1-1/4" so i used a reducer washer in the tailpiece extension.

    Does PVC pipe connections have any tolerance to be bent at all? Assuming it doesn't leak, it looks like perhaps i can get away not cutting the drawer if the p-trap leans directly against the vanity. It is a 5 to 10 degrees bend? Can I get away with it or does everything have to be perfectly square?

    Thanks for all help!

    You could have used 1 1/4" tubing and the trap would not even have touched the floor of the cabinet, so not need for the "offset".

    what a great idea. Its amazing how sometimes such obvious solutions can allude you. I was fixated on using the biggest "pipes" I can. However, this is not a toilet or a shower... It is a sink an a powder room...
    I still luckily haven't "glued" anything in yet, so I will give the 1-1/4" a shot this weekend. Thanks!
