A handyman or plumber installs kitchen and bathroom sinks. Undermount sinks may require a countertop installer to position and secure the sink and a plumber or handyman to connect the plumbing.

Plumbers charge $230 to $650 for labor to remove the existing sink and install a new sink. The cost to hook up a sink depends on the type and whether the installation includes a faucet or disposal. Installing a pedestal or undermount sink costs $230 to $800 in labor.

Sink installation takes 1 to 8 hours, depending on if it's a new install or replacement. Sink type, shape, weight, and faucet differences also affect the installation time. Replacing a sink with an exact duplicate takes the least amount of time.

Many farmhouse sinks install on an existing countertop by removing the countertop front and upper cabinet face. Most cabinets need reinforcement due to the sink's weight.

Start by searching our list of sink installers, then compare reviews and costs. Next:

• Get at least three estimates to compare.
• Look for licensed contractors or plumbers with sink replacement experience.
• Browse their reviews on HomeGuide and Google.
• Select companies that are insured, bonded, and have been in business for more than five years.
• Avoid selecting the lowest quote as quality may suffer.
• Get a detailed estimate, contract, and warranty in writing before the work begins.
• Never pay in full before the installation starts. Use a payment plan instead for work completed.
