You must have another spot for the litter box…bedroom, laundry room? Anywhere is better than that I think. I have an enclosed box in my laundry room, the actual litter box is hidden.

I would look for alternative spot. Do you have a closet that you could open side wall and create litter box spot? Much better to get out of “people” space. I did this in a very tight condo in New York. Worked out very well. Here is rough sketch. Do you have spot like this?

Custom sized litter boxes, I should pitch it on Shark Tank.

Seriously, what I've done is measure the available space, go to the store (Bed, Bath & Beyond or Walmart or Home Depot or Lowes, etc.), and buy largest plastic box that fits the space. If it's tall, may have to trim one side to make it more accessible if kitty is not a jumper.

Good luck and thank you for providing kitty a home.

I have a litter box upstairs, but with two cats in a two-story townhome, I introduced a second litter box downstairs after the cats had accidents before getting to the litter box upstairs.  My downstairs is all an open Floorplan, but I could possibly use the closet under the stairwell with some organization as a location for their litterbox. Will need to hire a closer organizer to help with it. Been meaning to, anyway. ὠ0

What about a wall hung sink, no storage underneath.

As a feline rescue/shelter volunteer I see too many kitties who lose their homes for inappropriate urination.

A contributing factor to this condition is litter boxes not kept scrupulously clean. (Would you want to use a bathroom with the odor of urine/feces that is also visible?) Cats sense of smell is much stronger than humans.

Litterboxes out of sight, can become out of mind - when it comes to minimum twice daily scooping and weekly deep clean with litter change.

I have a wall mount sink in a tiny powder room. I have a trash can knocking around under there and I know a litter box would work. Mine's about 65 years old so it's probably discontinued but some are quite nice. I'd try to find a wide one for even more discretion.

And yes of course the litter box goes in the powder room. It's where one poops, cat or man. It's the most sanitary option. :)

Depending on what your options are, I think a sink in a built-in vanity should provide enough space for a litter box. I realize it’s not ideal but if you want it here in the bathroom a vanity with sink from someplace like Lowe’s is not very expensive.

Wall mounted sink is your way to go. They come in many different sizes.

***Probably best option.

An alternative.

They also make vanities with sliding doors that might work so you dont have a door hanging open.

I like the vanity idea because it will contain the litter from the cat box a bit better. I don’t know about your cat but my cat is constantly tracking little bits of litter not to mention looking at the cat box… Not exactly attractive. You can put a small rug in by the entranceway and it will help to clean the litter off the cats feet as it exits the box.

My last cat was pretty sloppy...the idea of crawling into a cabinet to ugg never mind i can't even...

:P

Sounds like you need two locations. So perhaps two boxes are needed. Along with brush off pads outside boxes. Maybe you could decorate in fun way with craft paints.

Can we see pictures of the kitties?

Wall mounted sink will always give you more space. And the kitty.

🤣🤣 Fori you have a point… I had to build up the walls of my cat box because cat missed the top of the box on a regular basis.

Maybe the wall-mounted sink with a tension rod holding a curtain in front of the cat box? With a little space at side for the cat to go in and out and then the tension rod is easily removed for cleanups.

Here’s ours. Our plumber used PVC (ugh) and we hang a curtain with a rod to hide the box and ugly plumbing. It works to have the litter box with the lid.

I would have the box in a place with a water source to wash your hands after scooping. I have two boxes in my utility/laundry room.

Gorgeous kitties! They look like sweet little lovies.

Annie and Jack are beautiful kitties!

Tell the plumber the under sink will be exposed and you want it as aesthetically pleasing as possible. My undersink is exposed and plumber initially put in PVC, fortunately village building inspector told him to change it.

How’d it turn out?

If you decide to have the underside of a wall-hung sink visually exposed and want it looking neat, check out Duravit.com. Duravit sells matching pedestals that do get in the way, but also ”siphon covers” that hang on the wall and hide the plumbing behind a porcelain cover that only goes halfway to the floor. They also sell countersinks, in which there is a sink in the middle or one side or the other of a large porcelain countertop, all one piece. A larger, deeper one of these can give the litterbox more cover. You can also get a cheap vanity and cut a cat door in the side of it and use a tray with higher sides to try and capture litter that escapes the box. With two doors on a frameless front, you should be able to pull out the tray to brush it off and wash it. You could also look into furniture pieces that are made to hide the litter box and could look nicer. An activated charcoal filter hung in there and changed regularly could make a cabinet cat box smell better without adding perfume that the cats probably would not like. That works pretty darn well in the Toto deodorizing toilet seats.

Are they Magic treehouse cats?
