What’s the cost of installing a wall mount sink? The contractor cost to install a wall mount sink is $422 vs. doing it yourself for $300 and saving 28 percent.

Today’s wall mount sinks are a far cry from the basic white basins we all see in public washrooms. Whether your taste goes for the simple lines of a serene bowl or a more shapely curved and sculptured design, you have the opportunity to transform a boring bathroom from blah to spa with the addition of a wall-hung sink. And for tight spaces you’ll find wall mount sinks that are designed to fit in the tiniest of corners or crannies.

A plumber will install a moderately priced, wall mount sink for $422, which includes labor and material; or you can buy one for $300 and install it, pocketing a 28 percent savings. That’s assuming there’s already a plumbing line in the wall so no new pipes are required. If that’s the case, it will cost considerably more to add new water lines.

The installation requires blocking behind the wall to support the weight of the sink so some carpentry work is needed. Manufacturers have different installation methods but most of them involve cutting a hole in the wallboard and notching the wall studs for blocking with a piece of 2-by-10 lumber that is cut and nailed or screwed in place. Then the wallboard is repaired and finished and a mounting bracket is secured to the blocked wall where the sink will be installed.
