A typical bathroom remodel can cost anywhere from $16,000 up to $50,000, depending on the size of your room and the materials you choose. A minuscule fraction of that cost goes toward plumbing -- running water lines and connecting everything to the main sewer line. The average cost for plumbing a new bathroom runs about $250, which doesn't seem like much. However, getting the plumbing just right is vital for the success of your project. If you make any one of the following plumbing mistakes, you may end up having to pay more plumbing and/or permit fees. 

Plumbing Before Purchasing Fixtures

While fixtures don't go in until you have the entire bathroom plumbed and get the go ahead from the inspector, you can't wait until those things are done to go shopping. You must purchase your fixtures and measure them before your plumber can figure out where to place lines and drains. You see, fixtures have to be so many inches apart to meet the code regulations in your state. If you plumb first and get your fixtures later, you could end up having to remove the fixtures and start over when the inspector won't sign off on your project. 

Plumbing Before Deciding on a Layout

You must decide on a layout and measure all your fixtures before having a plumber run lines in your bathroom. A drain that is a couple of inches off in either direction may make it impossible to install your fixtures. You should also never let your plumber choose the layout for you. Instead, choose a layout that works for you and your family and tell your plumber what you want. That's the only way you will get exactly what you envision. Of course, if a layout is physically impossible, your plumber will let you know.

Saying No To Special Plumbing Features

Some plumbing features, such as a thermostatic mixing valve, may seem unnecessary, especially if you're trying to save money. Used to maintain a constant shower temperature even when someone flushes a toilet, a mixing valve can be easily installed while your plumber is running lines for your new bathroom. If you wait until later, you will have to open up the wall, which will cost you more money.

Plumbing is one of the least expensive costs associated with a bathroom remodel. However, you can end up spending more money than you should if you make any one of these mistakes.
