How much to install a sink dispenser? A plumber charges $311 to install a sink dispenser vs. doing it yourself for $158.

Ask anyone who has a hot water dispenser at their sink, and they’ll probably tell you it’s a convenience they can’t live without. These devices heat water to near-boiling (190 degrees) so they can be used for a lot more than instant cocoa. Use them with dry mixes to make hot soup, gravies, packaged stuffing or to blanche vegetables and parboil rice and pastas for casseroles. The hot water tank sits below the sink in the base cabinet, so you have to give up some space to make room for the unit. Its spout is mounted in a precut hole on the top of the sink counter.

If there’s a garbage disposer or dishwasher, they are connected to an electrical receptacle under the sink. You can use it for the dispenser.

A plumbing contractor will charge $311 to install a new dispenser, assuming there’s a receptacle to tap into. That includes labor and material. If you have some plumbing experience and tools, you can do the job; the only challenge is working on your back to reach all the connections. You can buy a unit for $158 and install it, saving 49 percent. You’ll need an electric drill and bits, basin wrench, saw, tubing cutter, screwdriver, pliers, adjustable wrench and a carpenter’s level. A saddle valve or three-way valve angle stop comes in handy to tap into the pipe without having to cut it first.
