Living in a small apartment with a cat — or two — means making every square foot count. The litter box is one of those things that has to exist, but it doesn’t have to take over your space or assault your nose. The best litter boxes for small apartments balance compact dimensions with effective odor control, easy cleaning, and design that doesn’t scream “litter box” from across the room.
We’ve reviewed the top options specifically for apartment dwellers, focusing on footprint, odor containment, litter scatter prevention, and aesthetics. For placement tips and setup ideas, check out our litter box setup guide and our guide to litter box placement in a small home.
What to Look for in a Litter Box for Small Apartments
- Compact footprint: Dimensions that fit in bathrooms, closets, or tight corners
- Odor control: Hooded, top-entry, or filtered designs keep smell contained
- Low litter scatter: High walls, top entries, or mats minimize mess on your floors
- Easy cleaning: You’re in close quarters — cleaning needs to be quick
- Aesthetics: Designs that blend in or can be concealed in furniture
The 6 Best Litter Boxes for Small Apartments
1. IRIS USA Top Entry Cat Litter Box — Best Overall for Apartments
Top-entry litter boxes are a revelation for small-space living. The IRIS USA Top Entry design requires cats to jump up and in through the lid, which does two important things: dramatically reduces litter tracking (the grooved lid catches litter from paws on exit) and completely eliminates side-spray for male cats who aim high.
The IRIS comes in at roughly 20″ x 16″ — compact enough to fit in most apartment bathrooms — and stands about 15″ tall, with walls high enough to contain most digging cats. The removable lid snaps on and off for easy scooping access, and the entire unit is lightweight enough to move for cleaning. There’s no filter or mechanical parts to maintain.
At under $30, it’s also one of the best-value options in this roundup. The main caveat: very large cats or senior cats with mobility issues may struggle with the top-entry design. But for healthy adult cats in tight spaces, this is our top pick for apartment living.
Pros:
- Minimal litter scatter — grooved lid catches paw debris
- Eliminates side-spray completely
- Compact footprint for bathrooms and closets
- Affordable and easy to clean
- No filters or parts to replace
Cons:
- Not ideal for large, senior, or mobility-limited cats
- No built-in odor filter
- Some cats refuse to use top-entry designs initially
Best for: Healthy adult cats in apartments where litter scatter is a primary concern.
2. Modkat Flip Litter Box — Best Design for Style-Conscious Apartments
The Modkat Flip is for the apartment dweller who wants a litter box that doesn’t embarrass them when guests come over. With its clean, modern lines and matte finish available in multiple colors, it’s genuinely attractive — something very few litter boxes can claim.
The “Flip” refers to the lid, which can be configured in three positions: fully open for easy scooping, half-open as a hooded box with reduced odor escape, or fully closed as a top-entry box. This versatility means you can match the configuration to your cat’s preference and your current cleaning schedule. The interior tarp liner is reusable and makes full cleans a breeze — lift, dump, wipe, replace.
At roughly 16″ x 20″, it has a similar footprint to the IRIS but a distinctly more premium feel. The price reflects that — it’s one of the pricier options here. But if your litter box is in a visible area of a small apartment, that design premium may be worth every penny.
Pros:
- Genuinely attractive design that blends into home décor
- Three lid positions for flexible use
- Reusable tarp liner makes cleaning fast
- Good odor control in hooded or top-entry mode
- Built-in hooks for bags or scoops
Cons:
- Higher price point than basic options
- Liner needs replacing periodically (added cost)
- Smaller interior than some jumbo-sized options
Best for: Style-conscious cat owners in apartments where the litter box is in a visible area.
3. Catit Jumbo Hooded Cat Litter Pan — Best Hooded Box for Apartments
When you need a traditional hooded box that still fits in an apartment, the Catit Jumbo Hooded is the go-to. Despite the “jumbo” name, its footprint is manageable at about 22″ x 18″, and the full hood with door flap keeps odors contained far better than open-top boxes.
The door flap keeps odors inside between scoopings and gives cats the privacy they often prefer in busy households. The hood lifts off completely for easy access during cleaning, and the base has a built-in rim to help keep litter inside. A carbon filter in the roof passively reduces odor — no electricity needed.
For apartments where the litter box is in a bathroom, this classic hooded design is familiar, reliable, and effective. If you have two cats, you’ll want to look at litter boxes specifically for multiple cats, but for a single cat in a small apartment, the Catit Jumbo hits the sweet spot of size and odor control.
Pros:
- Full hood dramatically reduces odor escape
- Carbon filter for passive odor absorption
- Privacy flap keeps cats comfortable
- Easy to clean — hood lifts fully off
- Affordable price point
Cons:
- Larger footprint than top-entry options
- Some cats dislike enclosed spaces
- Door flap can deter box-shy cats
- Not the most attractive design
Best for: Single-cat apartments where odor control is the top priority and the litter box is kept in a bathroom or closet.
4. Nature’s Miracle High-Sided Corner Litter Box — Best for Tight Corners
The Nature’s Miracle Corner Litter Box is one of the few litter boxes specifically designed to fit in a corner — which is exactly where most apartment dwellers want to put one. Its triangular footprint takes a corner that would otherwise be wasted space and turns it into a usable litter box area.
The high sides (about 10″ on the tall walls) contain spray and reduce litter scatter while keeping the unit open-top for easy scooping without removing a lid. The antimicrobial plastic inhibits odor-causing bacteria between cleanings, and the non-stick coating makes wiping out clumps faster than standard plastic.
The open-top design means odor isn’t fully contained between scoopings, so this works best if you scoop daily. For corner-placement in a bathroom or laundry area, the shape is genuinely space-efficient. A corner box that normally would require a larger dedicated footprint fits neatly here.
Pros:
- Corner-fit triangular shape maximizes space efficiency
- High sides reduce spray and scatter
- Antimicrobial plastic reduces bacterial odor
- Non-stick coating for easier cleaning
- Easy scooping with open top
Cons:
- Open top doesn’t fully contain odors
- Requires daily scooping for odor management
- Some cats feel exposed without a hood
- Smaller interior than hooded boxes of similar price
Best for: Apartments with tight corner spaces in bathrooms or laundry areas where a traditional rectangular box won’t fit.
5. Merry Pet Cat Washroom Bench — Best Hidden/Furniture-Style Option
For apartments where the litter box needs to be truly invisible, furniture-style enclosures are the answer. The Merry Pet Washroom Bench looks exactly like a storage bench — something you’d happily put in an entryway, bathroom, or bedroom — with a door on the side that opens to reveal a litter box interior.
The cabinet dimensions typically accommodate a standard-sized litter box inside, with a hole in the back or side for cat entry and exit. Litter stays inside the cabinet, odors are significantly muted by the enclosed wood design, and guests literally cannot tell there’s a litter box in the room. A small louvered vent panel allows airflow without releasing smell directly.
Setup requires assembling the furniture piece and placing your existing litter box inside. You’re essentially buying a furniture cover for a standard box. Cleaning is less convenient than open-access designs since you’re working inside the cabinet, but the visual benefit is significant for apartments where the litter box would otherwise be visible.
Pros:
- Looks like regular furniture — completely hides litter box
- Significant odor muting from enclosed wood cabinet
- Doubles as storage surface
- Works with your existing litter box
- Great for visible apartment areas
Cons:
- More expensive than standalone litter boxes
- Less convenient to scoop and clean
- Requires assembly
- Cat must learn to use the entry opening
- Not suitable as the sole box in a multi-cat home
Best for: Apartments where the litter box must be in a visible living area and aesthetics are paramount.
6. PetSafe ScoopFree Self-Cleaning Litter Box — Best Self-Cleaning for Small Spaces
If apartment living means limited time and limited desire to scoop, the PetSafe ScoopFree offers an automated alternative in a reasonably compact footprint. The unit uses disposable crystal litter trays that absorb urine and dehydrate waste, reducing odor dramatically compared to clay litter. The automatic rake sweeps waste into a covered trap 5, 10, or 20 minutes after use.
The crystal litter system means you’re replacing the whole tray every 2–4 weeks for a single cat rather than scooping daily. The trays are self-contained and relatively low-odor, which suits apartments well. The hood add-on (sold separately) further reduces odor and gives cats more privacy.
The main operating cost is the disposable trays. For apartment dwellers who value convenience over ongoing tray costs, it’s a worthwhile trade. For multi-cat setups, see our full review in our litter boxes for multiple cats guide.
Pros:
- Automatic raking — minimal scooping required
- Crystal litter dramatically reduces odor
- Compact tray design fits in small spaces
- Disposable trays make full cleaning easy
- Covered trap keeps waste out of sight
Cons:
- Ongoing cost of disposable trays
- Not all cats accept crystal litter
- Hood sold separately
- Not recommended for multi-cat homes without additional units
Best for: Single-cat apartment owners who prioritize convenience and low-maintenance odor control.
Apartment Litter Box Tips That Actually Help
Scoop Daily — It’s Non-Negotiable in Small Spaces
In a house, a dirty litter box might just smell in one corner. In a 600 sq ft apartment, it smells everywhere. Daily scooping is the single most effective odor-control strategy, regardless of which box you choose.
Use High-Quality Clumping Litter
Cheap litter crumbles when scooped and leaves residue that smells. Premium clumping litters (World’s Best, Dr. Elsey’s) form tight clumps that remove cleanly and reduce overall odor. The extra cost is worth it in a small space.
Consider Placement Carefully
Bathrooms and laundry areas are natural choices. Closets work well if ventilated. Avoid placing the box near food or in tight corners without ventilation — the smell will concentrate. Read our detailed guide on litter box placement in small homes for room-by-room recommendations.
Add an Air Purifier Nearby
A small HEPA air purifier near the litter box area makes a noticeable difference in air quality in small apartments. It addresses the ambient smell that even the best litter boxes can’t fully contain.
Frequently Asked Questions
What size litter box is best for a small apartment?
Look for boxes with a footprint under 22″ x 18″ — this fits in most apartment bathrooms without crowding. Top-entry boxes are often more space-efficient than hooded boxes of comparable interior size.
How do I control litter box odor in a small apartment?
Scoop daily, use clumping litter, choose an enclosed or hooded box, and consider an air purifier near the box. The combination of these four things will handle 95% of litter box odor in a small space.
Can I use a litter box in a studio apartment?
Yes. A furniture-style enclosure (like the Merry Pet Washroom Bench) or a stylish top-entry box like the Modkat Flip can integrate into a studio without dominating the space. Placement matters — corners and under-sink areas work well.
How many litter boxes do I need in a small apartment?
The standard rule is one box per cat, plus one extra. In a very small apartment, this can be challenging. If space allows only one box, scoop twice daily and clean weekly to minimize odor. For two cats, check our apartment cat setup guide for layout ideas.
Are self-cleaning litter boxes worth it for apartments?
If daily scooping feels unrealistic in your lifestyle, yes. Self-cleaning boxes significantly reduce the frequency of direct cleaning and keep odors lower between maintenance. The upfront cost and ongoing supply costs are the trade-offs.
Our Top Pick
For most apartment cats, the IRIS USA Top Entry Litter Box is the best starting point — compact, effective at containing scatter, and affordable. If aesthetics matter and your litter box is visible, upgrade to the Modkat Flip. If you have a corner to fill, the Nature’s Miracle Corner Box is clever use of space. And if you want it completely hidden, the Merry Pet Washroom Bench is the most seamless solution.
Whatever you choose, remember that placement and maintenance habits matter as much as the box itself. A great litter box, scooped daily, in a well-ventilated spot, beats a premium self-cleaning box that’s poorly placed and rarely cleaned.
