    Can bathroom pipes from the floor be moved closer together to install a pedestal sink
    Hi. My husband and I are remodeling our half bath. The pipes for the sink are coming up from the floor. They are about 7.5 inches apart, but the pedestal we bought only allows for about 5.5 inches from pipe to pipe. We got a great deal on the sink and really love it. Is it possible to move the pipes closer?

    We need more info.

    What type of floor is it? Concrete slab or wood framed? If framed, is area under floor finished? Crawl space? Finish on existing bathroom floor?

    The pipes can be moved. It just depends on how much u want that sink and how much work u are willing to do to install it.

    Get back to us with more info and we can guide u through the job.

    Good luck

    Are you on a slab? The back of the pedestal base has a opening. Is it just 5 1/2" or is it bigger then that? A lot of our advice will depend on the type of floor we're dealing with. Even if you're on a concrete slab it's possible to chip a depression in the slab and offset the pipes. So, that makes your pedestal sink doable. Regards. Tom

    Water pipes and waste pipe will not usually be set into the 5.5" space in the pedestal, so the water pipes are either exposed up the sides of the pedestal base (can be made to look like chrome), or the water pipes get relocated into the wall and stubbed out on the left and right side of the pedestal base at about 20-22" off the floor. Here, the water lines have chrome shutoffs installed and you want them to be accessible to shut off when needed... make sense?

    Anyway, answer the questions these guys asked, but I don't really see an issue here... just a need to chrome the water pipes and add shutoffs... maybe?

    Back to you...

    The bathroom floor has wood underlayment and we've already applied backerboard for the tile we're using. We haven't laid all the tile yet. Behind the wall is a garage wall that is drywalled. Under the bathroom is the basement. The water pipes come up from above the washer and dryer in the unfinished portion of our basement. Is it possible to move the pipes so they come out of the wall? How difficult is that to do? My husband has done a few plumbing projects before, but hasn't had to reroute pipes before.

    Thanks!

    What material are the water pipes. Galvanized. Copper or plastic? It should be easy to reposition the pipes in the basement, cut out the drywall in the garage and bring the pipes up. The drain should already be coming out of the wall. If the drain lines coming from the floor then your sink is unvented and has a "S" trap. Is this the case>? Back to you, Tom

    They're copper. Drain line is out of the wall. We have to cut into the wall to make the cross support for the pedestal basin, so can we reposition the pipes from that side of the wall?

    YEs! My suggestion was to remove the garage drywall and work from that side with the water pipes. Good luck, Tom
