Best Litter Box for Small Spaces: Three Compact Picks
As an Amazon Associate we earn from qualifying purchases. Details
The best litter box for small spaces is the one whose outside footprint fits your floor and leaves room for the door or lid to open. Floor area is only part of the choice. Wall height, entry style and whether the box has a cover all change how much room it takes up and how much litter reaches the floor. This guide compares three compact listings, says what each listing states, and shows what it leaves out. Specs come from Amazon listing data checked on 2026-10-20.
Quick answer
- Measure the spot first. Compare the listing dimensions with the floor, cabinet or corner you have.
- The three picks below have outside lengths between about 16.9 and 17.5 inches.
- Choose an open pan for easy access and a covered box if litter spray is your main problem.
- Check the current price on Amazon before you buy. This post does not list prices.
What a small-space litter box has to do
Three things decide whether a box fits a small space: the footprint on the floor, the inside length the cat needs to turn and dig, and the height of the walls. A narrow box can still feel cramped if the walls are tall. A low box uses less height but can let more litter escape. Use the listing dimensions as your starting point and then check them against the real space.
Outside size versus usable room
The dimensions in each listing are outside measurements. The listings do not state interior dimensions for every product, so the usable room inside a box is not fully known from the listing. Tape the footprint on the floor with painter’s tape and compare it with the outside size. Leave a few inches at the back and the front for the scoop and for your hand to reach the corners.
Height, sides and entry
An open pan with a low front makes entry easy for kittens and older cats. A covered box contains more litter spray and can hide the box from view, but it adds height and needs room for the lid to open. The right wall height depends on the cat. If your cat has joint, mobility or urinary concerns, ask a veterinarian which entry height suits that cat. This guide does not give health advice.
Where the litter goes
Small spaces tend to have less room for a mat and less room to step around the box. A litter mat under the box catches scattered litter, and the listings for two of the picks below do not include one. Our litter mat guide covers mat sizes and how to pick one for a tight floor.
Three compact picks
Each pick below is listed with an outside length of about 17 inches or less. The specs are copied from the listing data and are not measured by us.
1. Idymere Stainless Steel High Sided Cat Litter Box — the compact open pan
Specs (from the listing, checked 2026-10-20): Stainless steel; open top with high sides; outside dimensions 16.93 in L x 12.99 in W x 5.12 in H; item weight 1.8 pounds; target species listed as cat, medium cat and multiple small cats. The listing does not state a warranty or interior dimensions.
Pros (listing features): The listing says the smooth surface lets waste slide off instead of sticking, and that stainless steel does not trap dirt or odors the way plastic can. Raised sides are described as containing litter scatter. Cons and limits: The listing does not state a lid or a litter mat. It also lists rabbits, ferrets and snakes as suitable uses, which is a seller claim and not a fit guide for those animals.
Best for: A small floor where an open pan fits and the cat is a kitten, an older cat or a medium adult. Skip if: you want a covered box or a box that comes with a mat.

2. Camvivid Stainless Steel Covered Litter Box — the compact box with a lid
Specs (from the listing, checked 2026-10-20): Stainless steel; covered with a lid; listing includes a litter scoop and anti-skid stickers. The title gives 17.3 x 13.4 x 7.9 inches, while the product dimension field gives 17.5 in L x 13.5 in W x 7.9 in H. The listing does not state an item weight or a warranty.
Pros (listing features): High walls are described as a splash and leak barrier. The listing says the lid and main body are tool-free to detach for cleaning. The stainless steel is described as scratch resistant and free of artificial coating. Cons and limits: The two dimension figures in the listing differ by a fraction of an inch, so measure your space with care. A lid adds height, and the listing does not give the lid height.
Best for: A small space where a cover helps keep litter and spray in the box. Skip if: you need a low profile, or your spot leaves no room for the lid to lift.

3. Kirecoo Large High Sided Stainless Steel Cat Litter Box — the low-entry open pan
Specs (from the listing, checked 2026-10-20): Stainless steel; open top; 17.52 in L x 13.58 in W x 5.9 in H; the listing describes the sides as 6 inches tall; target species listed as cat. Item weight and warranty are both absent from the listing.
Pros (listing features): Open top with no lid to open, rounded edges and a smooth rim are described in the listing. The listing says the non-stick surface keeps litter from sticking to the bottom. Cons and limits: No cover is included, so litter spray is not contained beyond the walls. The category field lists reptile and small animal uses, which is outside the cat-only scope of this guide.
Best for: A compact open pan in a corner or under a shelf where a lid would be in the way. Skip if: you need a cover, or your cat is a large, high-spraying adult who needs more wall height.

How we chose
We chose from the listing data we had on file for this keyword. The first filter was footprint: each pick has an outside length of about 17 inches or less. The second filter was whether the listing states a cover, a wall height and a material. We did not rank by star ratings, review counts or sales rank, and we did not handle any of these boxes. Read the listing before you buy, and check the dimensions against your own space.
If you have a larger cat or a multi-cat home, a bigger box may suit better. Our guide to litter boxes for small apartments covers the trade-off between footprint and interior room in more depth.
What we could not verify
- Interior dimensions. The listings give outside measurements, so the usable inside room is not known for certain.
- Warranty for any of the three picks. The listings do not state a warranty.
- Item weight for the Camvivid and Kirecoo listings. The listings do not state a weight.
- The lid height on the Camvivid box. The listing does not state it.
- Whether a given cat will use a given box. Listing claims about odor, leaks and cleaning are seller claims and have not been checked against any cat.
A quick fit check before you buy
- Tape the outside footprint on the floor and mark the door swing or lid swing.
- Confirm the wall height works for the cat, and ask a veterinarian if you have a mobility question.
- Plan a mat if the floor is hard to clean. Our litter mat guide lists mats by size.
- Check the current price on Amazon and the seller’s return terms before ordering.
FAQ
What size litter box fits a small apartment?
Measure the floor first. The three picks in this guide have outside lengths of about 16.9 to 17.5 inches, which suits many compact corners. Leave room for the lid or door to open and for your hand to reach the back of the box.
Is a covered box better for a small space?
A cover can contain litter and spray, but it adds height and can reduce visibility for the cat. The right choice depends on the cat and the space. The Camvivid listing is the covered pick here, and the Idymere and Kirecoo listings are open-top pans.
Does any of these listings state a warranty?
No. For the three picks in this guide, the listings do not state a warranty. Check the seller’s page for return and warranty terms before you buy.
Do I need a litter mat with a compact box?
A mat helps catch scattered litter, and two of the three listings do not include one. A mat can also take up floor space, so measure it together with the box.
Should I ask a vet about box height?
Yes, if your cat has joint, mobility or urinary concerns. A veterinarian can tell you which entry height suits that cat, and can judge any health question that comes up.
Bottom line
For a small floor, pick the open pan if you want easy entry and a low footprint, and pick the covered box if you need the cover to contain litter. Use the listing dimensions to check the fit, then confirm the details the listing leaves out before you buy. For more size options, see our high-sided stainless steel guide.
