    I have paid for a three piece rough in an unfinished portion of my basement. I am unclear of the difrence between a two piece rough in and a three piece rough in. Can anyone educate me on this?

    Thanks
    Mike

    You mean for a tub/shower or shower unit.

    A 2 piece means 2 interconnecting wall, as 3 means 3 interconnecting wall.

    WE are not sure what you mean because the terms "two piece" and "three piece" are not usually used in that context. If you mean the number of items then two piece would be a toilet and sink. A three piece would add a shower or bathtub unit.

    You are correct, I should have been more clear. A two piece includes a toilet and sink and the three peice adds the toilet.

    When one says rough in what does that include? Particullarly for the sink. I cureently have a pipe extending out of the concrete for the toilet and the tub. There is no water lines run for the shower or the sink. How is rough in defined in the industry given the context?

    The three piece adds the tub, which is what I think you meant. Ruff-in means whatever the contract says. It could be just the piping under the floor, or all the drainage piping and vents, or all the drainage piping, vents, and water piping. It depends on what you paid for. Each level becomes more expensive, but there is no standard "starting" point.
