    Default Installing a new shower in a concrete floor, high-rise

    I just purchased a condo in a high-rise and am hoping to make some master bathroom/closet renovations. The condo layout is such that there is one large bathroom with a full shower/sink/toilet directly parallel to the master bedroom walk in closet which only has a small bathroom with a sink and toilet. My question is... Is it necessary to drill new drain holes in order to put in a second shower in the master closet or can I plum the drain to link to the next door shower drain? This would make things much much easier... If not, generally home much does installing a new drain in a high-rise condo with concrete floors generally run... ballpark? Thanks

    You will need to provide the shower it's own trap which means going through the floor (and in youir downstairs neighbor's ceiling). Code requires each plumbing fixture to have it's own trap (with a few minor exceptions).

    I don't think anyone here can give you a quote as cost can vary widely from area to area.

    If you are coring a prestressed concrete floor, you will need to x-ray the floor first.

    It's going to be a bunch.

    Depending on where you live, state and local laws, and the condo by-laws, any changes like this may need the association's approval. You may not get it. Local laws usually require this to be done only by a licensed plumber with permits. Depending on how the ceiling is done, and how friendly your downstairs neighbor is, you may not get permission to enter their unit unless it is something like to fix a leak. Tearing out the ceiling and restoring it could get ugly. Now, if it is a dropped ceiling, it may not be a big deal. You may need to not only move a drain, but install a new vent as well, so it is likely at least a couple of holes through the floor.

    Default shower

    As stated, there is NO WAY to tell what is involved until someone checks your existing piping to see what would have to be modified. BUT, all homeowner associations require that alterations be performed by licensed contractors, if for no other reason than liability and insurance coverage. For those reasons, you need a local plumber to check as much as he can, without disturbing your downstairs neighbor, until work starts. At that point, you would have to get permission from the downstairs person so you could access the pipes in his ceiling. Not always easy, or possible, with some people.

    Check out www.saniflo.com

    Sanishower is a small gray water pump that may be used to pump waste water away from a shower, sink, bar sink, or other fixture. The Sanishower is small enough to fit inside a wet bar cabinet, or even beside or underneath a raised shower base. It also can be used in a variety of small gray water pumping jobs, such as a condensate pump. The Sanishower will pump up to 12 feet in height.
