Getting a handle on the plumbing
The following sections show how to install the three major bathroom plumbing fixtures in a common configuration. You'll find quite a few variations on this basic arrangement. Your situation may call for pipe runs that differ from those shown, so you may need to develop a unique plan that suits your home.

You'll need a good understanding of the basic skills and techniques of plumbing. Pay special attention to the drain vents and make sure you use pipe types and sizes that conform to code. If possible hire a professional plumber to spend an hour or two giving you advice. This modest investment could save time and money later.

The entire project
Whether you are remodeling an existing bathroom or installing one in a new addition, you will need carpentry skills. Modifying the framing sometimes can make the plumbing work easier. Plan and install the plumbing so it damages joists and studs as little as possible; reinforce any framing members that have been compromised. It's usually best to run any electrical lines after the plumbing has been installed.
