Step-by-Step Instructions

1. Prepare the Vanity Top

• Place the vanity sink on top of the vanity top and center it.
• Trace the outline of the sink onto the top using a pencil.
• Remove the sink and cut out the traced area using a jigsaw or reciprocating saw.

2. Install Sink Mounting Brackets

• If your sink doesn’t come with mounting brackets, you’ll need to purchase and install them.
• Align the brackets with the holes in the sink and secure them with screws.

3. Apply Plumber’s Putty

• Roll out a bead of plumber’s putty around the rim of the sink.
• Smooth it out evenly to create a seal.

4. Place the Sink

• Lift the sink and carefully place it on the vanity top, aligning it with the cut-out and the mounting brackets.
• Press down firmly to ensure a good seal.

5. Tighten the Brackets

• Use an adjustable wrench to tighten the mounting brackets.
• Apply even pressure to prevent over-tightening and cracking the sink.

6. Install the Sink Strainer and Stopper

• Insert the sink strainer into the drain hole and secure it with the mounting nut.
• Install the stopper in the overflow hole, if applicable.

7. Connect the P-trap

• Assemble the P-trap and connect it to the drain pipe.
• Tighten the nuts by hand and then use an adjustable wrench to snug them up.

8. Connect the Supply Lines

• Connect the hot and cold water supply lines to the corresponding valves on the sink.
• Use a wrench to tighten the connections.

9. Apply Silicone Caulk

• Run a bead of silicone caulk around the perimeter of the sink, where it meets the vanity top.
• Smooth it out using your finger or a caulk tool.

Additional Tips

• Use a level to ensure the sink is level before tightening the brackets.
• Don’t over-tighten the supply lines or P-trap connections, as this can damage the fittings.
• Allow the silicone caulk to dry completely before using the sink.

Troubleshooting

• Sink is leaking: Check the connections and tighten if necessary. Replace the plumber’s putty if it’s damaged.
• Sink is not level: Adjust the mounting brackets or add shims under the sink.
• Water is draining slowly: Clean the P-trap or check for any blockages in the drain line.

Top Questions Asked

1. What type of sink mounting brackets should I use?

• Choose brackets that are compatible with the size and weight of your sink.

2. How much plumber’s putty should I use?

• Apply a thin, even bead around the rim of the sink. Too much putty can make it difficult to tighten the brackets.

3. Can I use regular caulk instead of silicone caulk?

• No, silicone caulk is specifically designed for bathroom applications and provides a watertight seal.
