5 Smart Laundry Room Litter Box Ideas: A senior interior designer’s real-world tricks to hide the box, cut odor, and keep your cat happy in the laundry zone

Years ago a client swore her cat would “love the spin cycle” and begged to put the litter box on top of the washer. I smiled, built a quick 3D mockup, and we both realized the first spin would catapult litter like confetti at a parade. Since then, I’ve turned many tight laundry rooms into cat-friendly, low-odor sanctuaries that actually function better for humans too.

Small spaces spark big creativity, especially when there’s a litter box involved. Drawing from dozens of real remodels (and a few whisker-worthy mistakes), I’m sharing 5 design ideas that balance odor control, privacy, and workflow—without making laundry day feel like a sandbox.

Idea 1: A vented cabinet with a side entry

Build a base cabinet with a side cut-out, line the interior with wipeable panels, add a tight-fitting door, and tuck a carbon filter plus a quiet PC or inline fan venting outside. The fan pulls odor away, while a deep, rimmed tray and a textured litter mat at the entry catch granules before they travel.

I like toe-kick slots for extra airflow and a magnetic hatch for scoop access. The upside is hotel-level discretion; the trade-off is a bit of carpentry and running power for the fan. Keep detergents up high, and use soft-close hinges so the cat isn’t spooked.

Idea 2: Folding bench on top, side-cubby for the box

Turn the laundry counter into a twofer: a sturdy folding surface above and a side-entry cubby below for the litter box. Use outdoor-rated paint or laminate inside the cubby, plus a silicone boot tray—when accidents happen, you’ll be grateful.

This layout keeps the action at human height while the cat enjoys privacy. If you’ve got kiddos, add a simple childproof latch. Noise is the only catch—add anti-vibration pads under the washer so the drum doesn’t scare your feline roommate.

Idea 3: Slide-out base drawer with a full-size tray

A heavy-duty drawer slide turns the litter box into a glide-out station for super easy scooping. I spec 100–150 lb soft-close slides, a high-rim tray, and a double mat “runway” right outside the drawer.

Mind plumbing and electrical clearances, and leave ventilation gaps so odors don’t stall inside. When I’m laying this out, I like to test the traffic flow to be sure the drawer clears doors, hampers, and human knees. Great access, minimal bending; just measure thrice so the box fits with the lid off.

Idea 4: Under-sink privacy niche with washable skirt or tilt front

If cabinetry is tight, carve a nook under the utility sink and hide it with a washable fabric skirt or a tilt-front panel. Add LED motion light inside—cats appreciate seeing where they step—and put a small louver or gap for fresh air.

Keep chemicals locked and elevated, and use GFCI outlets and splash protection. For clients needing visual direction, I mock up an AI-generated mood board to choose finishes that are wipeable and cohesive. Budget-friendly and fast to build, though you’ll trade some storage space beneath the sink.

Idea 5: Corner screen + raised platform to fight tracking

No cabinets? Set the box on a 3–4 inch platform and wrap the corner with a low, ventilated screen (think slatted wood or perforated metal). The platform lets litter shake off before exit, especially with a two-mat runway and a small rug beyond.

I add a wall-mounted scoop caddy and a sealed bin for dirty litter to cut smell. For odor hot spots, a mini carbon purifier helps, and a UV flashlight makes quick work of finding sneaky splashes. If you’re using a self-cleaning box, add vibration pads so laundry-day rumble doesn’t trigger feline vetoes.

FAQ

1) Where should I place a litter box in a laundry room?

Pick a low-traffic corner away from appliance doors and not directly beside the furnace or water heater. Ensure there’s ventilation, easy access, and no chemical splash risk.

2) How do I control odor in a small laundry room?

Combine ventilation (small fan or vented cabinet), clumping litter, daily scooping, and a sealed trash bin. Carbon filters and washable interior panels make weekly deep cleans painless.

3) Will washer and dryer noise bother my cat?

Some cats tolerate it; others don’t. Add anti-vibration pads, close doors gently, and give the box a partial barrier—observe your cat and adjust placement if you see avoidance.

4) What’s the ideal number of litter boxes if the laundry room holds one?

Most vets recommend one box per cat, plus one extra, spread across the home for choice. See the AAFP Feline House-Soiling Guidelines for details (https://catvets.com/guidelines/practice-guidelines/house-soiling).

5) Is a covered box better in a laundry room?

Covers contain scatter and help visually, but they can trap odor if ventilation is poor. If you use a cover, add airflow (vents, fan) and scoop daily to keep the interior inviting.

6) Which litter reduces tracking the most?

Heavier, larger-grain clumping litters track less than ultra-fine options. Pair with a textured mat and a short “runway” to catch clingy granules.

7) Can I build a DIY vented litter cabinet?

Yes—use a sealed box cabinet, cut a side entry, and add a quiet PC or inline fan with a carbon filter vented outside. Use wipeable surfaces and a removable tray for easy cleaning.

8) How do I keep cleaning supplies safe near the litter area?

Store detergents and bleach in upper cabinets with childproof latches. Choose a litter nook that won’t get splashed and add a small motion light so your cat can navigate safely.
