A “plumbing rough in” for a bathroom is simply a process of laying down the main lines, drains and intake pipes, without making the final connections. This is a process that will require you to lay pipes that will lead water into your main drain. You will also have to lay pipes that will lead water into the bathroom. The process will require buying materials that will be laid such as pipes, connectors, etc. For your bathroom to have a hot water system you have to lay lines where electric cables will pass through. For this reason the plumber and electrician usually work together on this project.
The job of a plumbing rough in for your bathroom will require digging trenches where the pipes will be laid. In order to ensure wastewater from your bathroom will be able to flow out, he should dig trenches that will be sloping outwards towards the main drain. If the main drain is located far away from where you will locate the bathroom you will have to pay more. In average the cost of digging the channels will cost about $1500. This of course depends on the hourly rate charged by the plumber. Depending on the type of materials you need and the length from the main drains to the house, the materials can cost $250 or more.
Hiring a Professional Plumber
After you hire a professional plumber they will employ sophisticated equipment to locate the main water lines and main drain precisely. This is necessary for them to dig trenches, which will connect the water from the bathroom to the main drain and those that will let in water. This will cost will vary depending on where you live, how long the lines will be and how involved digging the trenches becomes. Again, you will also need to involve an electrician, who will have his own fees for labor.
