How To Replace A Bathroom Sink: Steps to Get Ready for a New Sink

Step 1: Turn Off the Water

  • Find the water valves under the sink.
  • Turn both hot and cold valves clockwise until they stop.
  • Turn on the Faucet to drain the remaining water.

Step 2: Remove the P-trap

  • If your P-trap is plastic, loosen the nut by hand. If it’s metal, use pliers.
  • To clean the P-trap, unscrew it from the drain below.

Tip: Place a bucket or towel under the sink to catch any water.

Step 3: Disconnect the Water Lines

  • Use a wrench to unscrew the valves’ hot and cold water lines.
  • Some lines can be unscrewed by hand, but a wrench is often needed.

Tip: This is a good time to replace the old water lines if necessary.

Step 4: Measure the Old Sink

  • Use a tape measure to note the old sink’s length, depth, and width.
  • Measure the countertop space to make sure the new sink will fit.

Step 5: Buy a New Sink

  • Take your measurements to a home improvement store.
  • Make sure the new sink is the same type (top-mount or under-mount) as the old one.
  • Ask for help at the store if needed.

Tip: Check that the new sink’s drain lines up with the old drain to avoid extra plumbing work.

How to Replace a Top-Mount Sink

Step 1: Remove the Clips

  • Look under the sink for clips that hold it to the countertop.
  • Loosen these clips with your hands or a screwdriver.

Tip: Keep the clips in case you need them for the new sink.

Step 2: Cut the Sealant

  • Use a utility knife to cut through the sink and countertop sealant.
  • Carefully run the knife around the edge of the sink to break the seal.

Step 3: Lift Out the Old Sink

  • Grab the sink from above and lift it out of the countertop.
  • If it’s too heavy, ask someone to help by pushing it up from below.

Step 4: Clean the Area

  • Scrape off any leftover sealant from the countertop with a plastic putty knife.
  • Clean the area with a rag dipped in mineral spirits to remove any residue.

Step 5: Install the Faucet and Drain

  • Decide if you want to reuse the old Faucet and drain or get new ones.
  • Follow the instructions to install the Faucet and drain on the new sink.

Step 6: Put Caulk on the Sink

  • Apply a line of silicone caulk around the underside of the new Sink’s Sink’s rim. This will help keep the sink in place and stop water from leaking.

Tip: Use silicone caulk made for bathrooms. Don’t use other types of caulk.

Step 7: Place the Sink on the Countertop

  • Carefully lower the sink into the hole in the countertop.
  • Once it’s in place, press down on the sink and wipe off any extra caulk with paper towels.

Step 8: Secure the Sink

  • Attach the sink to the countertop using the clips that came with your new sink.
  • Follow the instructions to place and tighten the clips by hand or with a screwdriver. These clips will hold the sink in place.

Step 9: Seal the Sink Rim

  • Apply a silicone caulk line around the sink’s edge where it meets the countertop. This will create a waterproof seal.
  • Smooth the caulk with a wet finger and wipe away any extra with damp paper towels.

Replacing an Undermount Sink

Step 1: Cut the Caulk

  • Use a utility knife to cut the caulk that holds the sink to the countertop.
  • Be careful not to scratch the countertop as you work around the sink’s edge.

Step 2: Remove the Clips

  • Have someone hold the sink from below.
  • Remove the clips under the sink that secure it to the countertop. Use a screwdriver for screws or a putty knife for glued clips.

Tip: Make sure the sink is supported to prevent it from falling.

Step 3: Lower the Sink

  • Once the cask and clips are removed, lower the sink and remove it from the cabinet.

Tip: If you’re reusing the Faucet and drain, take them off now. Otherwise, you can install new ones later.

Step 4: Install the Faucet

  • Attach the Faucet to the new sink before you install the sink under the countertop.

Step 5: Apply Silicone Caulk

  • Put a continuous silicone caulk line around the new sink’s top edge. This will help secure it and prevent leaks.

Step 6: Position the Sink with Clamps

  • Cut a piece of 2×4 wood to be a bit longer than the sink opening.
  • Place the wood across the opening and use a bar clamp through the sink’s drain hole to hold it up from below. Tighten the clamp until some caulk squeezes out, then wipe away the excess.

Step 7: Attach the Clips

  • Secure the sink with the clips that came with it. Use screws or epoxy as instructed by the manufacturer.

Step 8: Wait and Install the Drain

  • Wait 24 hours for the caulk to fully cure before removing the clamp and wood.
  • After the caulk sets, install the drain and finish the setup.

Finishing Up and Testing Your New Sink

Step 1: Let the Caulk Dry

  • After putting in the top-mount sink, let the silicone caulk dry for 24 hours. This keeps the sink steady and the seal strong.
  • For undermount sinks, you should have already waited 24 hours before adding the drain. Now you can move on.

Step 2: Reconnect Water Lines and P-Trap

  • Reattach the hot and cold water lines to the valves. If necessary, tighten them by hand or with a wrench.
  • Reconnect the P-trap under the Sink. Use your hands for a PVC P-trap or pliers for a metal one.

Tip: If the new drain is shorter, get a P-trap extension and cut it to size. If it’s too long, trim the pipe with a hacksaw.

Step 3: Turn on the Water and Check for Leaks

  • Open the hot and cold water valves by turning them counterclockwise.
  • Turn on both faucet taps and let the water run for 2-3 minutes.
  • Look under the sink for any leaks in the water lines or pipes. Tighten any loose parts.

Tip: Keep a bucket or towel under the sink while checking for leaks.

Bonus: If you find a leak, turn off the water, take apart the connection, wrap the plumber’s tape around the threads, and reconnect. If the leaks continue, you might need to call a plumber.
