How to Fix a Gap Between Bathroom Sink and Wall

A gap between your bathroom sink and the wall can be an eyesore. It can also allow water to seep behind the sink, causing damage to your wall or cabinets. Fortunately, there are a few simple steps you can take to fix this problem.

Materials You'll Need

Caulk gun
Caulk
Utility knife
Sponge or cloth

Instructions

Clean the gap. Use a damp sponge or cloth to remove any dirt or debris from the gap between the sink and the wall. Make sure to get into all the corners.
Apply caulk to the gap. Load the caulk gun with a tube of caulk. Cut the tip of the tube at a 45-degree angle, and then insert the tip into the gap. Apply a thin bead of caulk to the gap, starting at one end and working your way to the other.
Smooth the caulk. Use your finger or a damp sponge to smooth the caulk. Be sure to get into all the corners and crevices.
Allow the caulk to dry. The caulk will need to dry completely before you can use the sink. The drying time will vary depending on the type of caulk you use, but most caulks will dry within 24 hours.

Tips

If the gap is large, you may need to use a backer rod before applying caulk. A backer rod is a piece of foam or rubber that fills the gap and prevents the caulk from sagging.
If the gap is caused by a loose sink, you will need to tighten the sink's mounting bolts before caulking the gap.
To prevent the gap from recurring, apply a bead of caulk to the gap every few years.

By following these simple steps, you can easily fix a gap between your bathroom sink and the wall. This will not only improve the appearance of your bathroom, but it will also help to prevent water damage.
