Fill Gap Between Vanity and Wall?

The builder of our home put a builder grade bathroom vanity against two walls in our downstairs bathroom. He caulked the small gap between the side of the vanity and the wall. I’ve re caulked it several times - it’s always drying up and looks terrible. What fix would you recommend? Is there something that would last better? What’s the best way to get the old caulk off the vanity and the wall?

Where side of vanity meets the wall.

  • I would be tempted to put a pretty thin piece of moulding there to cover the gap.

    Use a widget (a gadget that holds a single edge razor blade) and CAREFULLY remove the excess caulk. Next, have a look at the gap and measure how wide it is. Now, take a look at the molding along the floor of the room. Find something similar that matches the decor and paint it the color of the molding. Cut to fit and you can attach it with nails, glue or whatever you like. That should fix the problem and you won't have to worry about matching colors with either the wall or the cabinet.

    It shouldn’t be moving all the time and cracking. Check out why this is happening and stop the movement.

    I like the molding idea and since it’s going to be tiny, it will split if nail holes aren’t pre-drilled.

    I would consider double stick taping it or mastic’ing to whatever is not moving, the wall or the cabinet.

    Molding would be the easiest permanent fix. Buy some quarter round and nail it on.

    I think piece of decorative molding or quarter round strip will for sure fix that and add a beautiful detail


  • I agree, a piece of trim will work well. Attach it to one or the other, not both as you seem to have a movement issue.

    Caulking won't work here, not without filling that crack with shims to make a really tight wedge to stop any movement. Pound them in to just so slightly below the edges, fill with spackle, sand smooth when really good and dry and paint. The widget is a good idea to remove caulk and get a smooth surface first. The building supply store will help you with all of these supplies if you aren't sure what they are. Good luck, you've got this. :)
