How do I make a bathroom vanity fit better?


We are installing a new bathroom vanity in our half bath. The walls are not square so it doesn't fit snug. I am worried about water and the gap. Any ideas?

There is a full baseboard. Notch it? Or add tile trim to sink?

    Notch the baseboard for sure. Plus you can add decorative tiles for backsplash.

    Hi Pam: You can put backer rod (it's foam that looks like a pipe and is flexible and comes in different thicknesses) in the gap and then caulk around it. Have a cup of water handy so you can wet your finger and smooth the caulk out. It's easier to do with a wet finger. Good luck

    I would use silicone caulk to seal the gap, and notching the overlapping edge could help with a smoother transition, as Kelli indicated.

  • Caulk is your friend here, it’ll keep water and such out of the gap.

    Unless you're a real pro at caulking, it could end up looking pretty bad with that much of a gap. I'd think about painted wood perimeter trim, with minimal caulking to seal the edges. Notch the baseboards, too.

    Quarter round trimming to cover the gap. W/ waterproof caulking top and bottom.

    You can carefully remove that baseboard and cut it to fit tight against the side of the vanity. I don't think you'd really need it under/behind the vanity.

    I agree with Kelli and Gk. Remove the baseboard behind and side so the vanity sits more flush against the wall then you can caulk the small gap. I also suggest a backsplash. Anything else would look off and sloppy.
