Plumbing in the Home/Rough-in Bathroom Plumbing

Question
Dear Dana,

We are buying a new home from a builder. The home has a 3-piece plumbing rough-in (for full bathroom). What we see in that room are two drain pipes. Should the incoming water piping be included in the rough-in? Should the electrical wiring for the vent fan included?

Thanks in advance.

Sincerely,

Cindy

Answer
Hi Cindy,
I assume this is a basement bathroom set up. That is the most common "future rough-in" I see.

The waste lines are a bit more flexible in their location however water lines need to be pretty precisely located and if they were pre-plumbed and stubbed out they might not match what you ultimately choose to install.

As an example,the water lines are stubbed out differently for a pedestal lavatory then they would be for a sink mounted in a vanity.
Also, the control valves for a stall shower would be mounted at a different height then those supplying a tub / shower.

I would think there should be at least a hot and cold water supply stubbed in somewhere with shut off valves that could then be extended to the locations as needed for your fixtures. A bathroom vent fan is optional depending on the building code in your area. While nice to have, it may not be mandatory.

It is not that difficult for a plumber and electrician to bring these services to the area of your bathroom as needed since I assume it has not been built out yet.
Good luck,
Dana

Pretty much any residential plumbing questions. For "item specific" details such as a specific model of fixture, I will need to research and there may not be any useful information available. Note: I live and work in Southern California. We do not, as a rule, use hot water or steam heating systems, oil fired boilers or private water wells so my knowledge in those areas is pretty limited. There are others here on AllExerts that can probably answer those questions better.
