The average price to Install a Three Light Bath Bar noted above is cost data to compare a contractor’s estimate with doing it yourself.
How much does it cost to install a bath light bar? The contractor cost to install a three-light bath bar is $135 vs. doing it yourself for $78 and saving 42 percent.
Who knew replacing an ordinary bathroom light fixture could involve so many choices? If you take a walk through the lighting section of any home or bath center, you’ll see an array of bath light bars for over a vanity, all designed to enhance and improve your bathroom and its lighting.
We found styles that complement any décor, from sleek contemporary chrome to textured rust and iron scrollwork finishes with clear glass, frosted, alabaster, and Tuscan-like shades. Three-light bars, ranging from 22 to 36 inches wide, are a popular choice because they fit nicely over a typical single sink vanity cabinet.
To remove an old bar fixture and replace it with a new, quality 28-inch wide 3-light bath bar, an electrician will charge $135, which includes labor and material. You can buy the new fixture for $78 and make the swap yourself, pocketing a 42 percent saving.
If the base of the old bar is larger than the new one, the new fixture won’t be covered. In that case you’ll probably have to fill in around the hole and repair the wall. That translates to repainting or wallpapering before the new fixture is installed. To avoid that extra work, choose a new light bar that is the same height and width of the old one.
