Yes, it is often possible to replace an undermount sink without removing the countertop, but success can depend on the countertop material. For materials like granite, the process is relatively straightforward. However, laminate or uniquely shaped countertops might need to be removed or modified.

The process typically involves shutting off the water supply, disconnecting the drain and plumbing pipes, cutting through the old silicone seal, and carefully lowering the sink from below. This requires a good understanding of plumbing and the right tools. If you are not confident in performing the replacement yourself, it is recommended to hire a countertop specialist or a plumber to handle the task.

Undermount sinks have clips that attach to the countertop, but they have pros and cons. They are heavier than drop-in sinks, so they only work with sturdy countertops like natural stone and are a more expensive option. You might need someone to help you install the sink, depending on its weight.

Depending on the issue and materials, costs range from $150 to $500.

Deteriorated seals, O-rings, or gaskets are common culprits behind a leaky sink after you’ve turned off the water—especially if your sink is older than 15 years. Inspect each of these mechanisms in your sink for signs of corrosion or looseness, then replace the worn-out part to fix it. Older sinks may be worth replacing if several of the parts are worn-out.
