    Have you confirmed that the drain pipe on the left side of the opening is going to work with this cabinet? It looks very close to being at the same height as the bottom of the doors. Will you be able to fit the trap in there? It would be a real bummer to have that pipe hit right where the shelf is.

  • Is 48" the width of the cabinet or the countertop?

  • Open up the drywall on the left side and see if you can move the drain around to the back. It looks like there is some electrical in the way but I am not sure. Then finish the area drywall and floor and install your cabinet centered. Commented Jun 24, 2022 at 14:10

    Side note, but is that - carpet? In a bathroom? There's a reason they don't usually do that. If it gets wet frequently, you'll have a serious mold problem on your hands. Hope you're planning on taking that out as part of this remodel. A small, moveable rug is fine to keep your feet warm/dry after a shower - you can clean those easily, or replace them when they get really nasty. But wall-to-wall carpet is very hard to keep clean in a wet environment. Commented Jun 24, 2022 at 18:32
  • Hey 48 inches is the width of the countertop, also the carpet will be replaced with tile. Commented Jun 24, 2022 at 22:57

This is a free standing vanity. It is not made to finish against a wall. The cabinet part does not lend itself to adding what we call "fillers" as a standard vanity cabinet would. The open shelf on the bottom is the main culprit for this.

Anything you do to try and add onto the countertop itself is going to look bad- it will look like what it is- an unnecessary add on.

You are better off to just do a good job on the drywall repair and mount your cabinet/ countertop as it was designed to be installed- centered between the walls with a space on each side.

I cannot see any way to make this look better than that.

Otherwise, get a 48" standard box cabinet and 2- base fillers which you cut down to 1 1/2" each to fit wall to wall. Then procure the correct size countertop (and matching backsplash).

    I think disguising the waste pipe coming out the side might be useful for aesthetics, but that should be focused on the pipe rather than the cabinet. That said, I'm not sure how the vanity will fit into the space without building it in place, or disassembling it, because of that pipe. Commented Jun 23, 2022 at 15:11
  • I had something similar with a 2" gap on one side of my vanity, and definitely understand the desire to fill it in. Cleaning inside the gap would be annoying, not to mention the aggravation of dropping an item and having to fish it out with a yardstick. I used the same filler for both the vertical and horizontal surfaces, with the horizontal piece sitting just below the bottom edge of the ceramic vanity top. I don't see a big issue with the open bottom shelf, just add a panel on both sides to prevent items falling off the shelf into the gap. Commented Jun 23, 2022 at 16:28
  • Yes, with a bunch of work you could make this built in looking. My point is why bother ? Either use it as intended (free standing) or get a proper cabinet/ countertop set up. Also, I totally agree that cleaning around this freestanding unit in such a tight space is a nightmare...

  • When gaps are this tight, take extra time to ensure that the vanity is properly centered. Being off by a smidge could make the gap on one side twice the size of the other, which will stick out as very obvious.

  • @NuclearHoagie Definitely seconded. We have one of those little gaps between a vanity and the tub--annoying. Commented Jun 24, 2022 at 0:22

I think I might try pushing the cabinet all the way to the left, leaving a gap of about 3" on the right.

Then mount a towel bar all the way across, maybe 12" above the countertop or so.

Then hang a bunch of long fluffy towels in there.

  • This is a good idea. If doing this, I might consider trimming the countertop flush with the cabinet body on the left edge.

  • I like this idea, actually i saw they make 3 inch spice cabinet fillers that pull out, maybe i could store haircare products and what not in the pull out amazon.com/Hardware-Resources-Dead-space-Technology-Eliminate/… Commented Jun 26, 2022 at 23:44
  • What would you put on top of the spice cabinet to finish the countertop?

Because of the layout of the drain, you are probably best returning the free standing vanity and going back to a built in. You are going to spend many days trying to fix walls and deal with the drain. In the end, if you stick with the ill fitting vanity you won't be satisfied. Sorry.

  • Are those walls perfectly square? Commented Jun 24, 2022 at 20:21
