The Easiest Way to Remove a Kitchen Sink

Removing a kitchen sink might sound intimidating, but with the right approach, it’s easier than you think. Whether you’re planning to upgrade to a modern undermount, swap out a stained basin, or simply start fresh, knowing the proper steps can save time and frustration. By preparing your workspace and tackling the removal methodically, you’ll have the old sink out in no time.

The first and most important step is shutting off the water supply. Locate the shut-off valves under your sink and turn them clockwise until they’re fully closed. Then, turn on the faucet to release any remaining water in the lines. This prevents unwanted leaks while you’re working and keeps the space manageable.

Next, disconnect the plumbing connections. Start with the P-trap under the sink by loosening the slip nuts with pliers or a wrench. Be sure to have a bucket or towel handy, as water often remains in the trap. If you have a garbage disposal, disconnect the power supply and remove it according to the manufacturer’s instructions. This clears the way for safe sink removal.

Once the plumbing is disconnected, turn your attention to the mounting hardware. For drop-in sinks, this means loosening the clips located beneath the countertop rim. For undermount sinks, you’ll need to carefully release the brackets and cut through any adhesive or caulk securing the sink to the underside of the counter. A utility knife works best for slicing through old silicone or sealant.

Finally, it’s time to lift out the sink. For drop-ins, gently push upward from underneath to break the seal, then lift the sink out of the countertop cutout. For undermounts, carefully lower the sink out from beneath once it’s fully detached. Take your time here—sinks can be heavier than expected, especially if they’re cast iron or fireclay. Once removed, scrape away old caulk and clean the area to prep for your new installation.
