We're building a new home and paid for the rough-in plumbing for a basement bathroom. In the model, (which I have been told is not customizable outside their allotted plans) the roughed-in lines were along the stairway in a good location for a future bathroom. When we were asked to do our pre-drywall walkthrough, we noticed that the drains were located more into the center of the basement which is totally different from the model and very inconvenient to add a bathroom without breaking up the concrete and moving 2 of the 3 drains.

When I asked the builder, they told me that "rough in" meant a rough location as well as no fixtures. Since this is my 1st built home, I was wondering if the location of the plumbing is subject to any location in the basement? Bottom line, I want the drains where they were in the model. Any insight would be greatly appreciated.

I did not receive any prints nor was I asked to approve the location or told the location for the rough in was different from what was in the model. I have been told that I cannot change anything from what is offered in their plans as the house is "not a custom built home". Typically, can I request a copy of the basement plans as drawn?

    Rough in means putting the plumbing exactly were is specified to be on the plans or otherwise instructed.

  • If you were offered to rough-in a bath in, say, an unfinished upstairs in a Cape Cod, they'd put sensibly the drain and hot and cold all in one place. In the basement it should be no different.

  • Typically you'd have signed off on plans before construction began. What happens now is up to your builder, apparently.

There are really no code requirements to be met with respect to location other than meeting clearances and that sort of thing. For example, a toilet must be so far from walls to the side. Anything else is a matter of prerogative and your contract.

It sounds like you have a contract dispute here, and that's off-topic on this network. If you approved a plan, and if the plumbing was installed according to plan, you'll have to fix it yourself. Otherwise, I'd expect the builder to do it.
