Quick answer: To make an IKEA litter enclosure in a rental, choose a cabinet at least 20 inches deep with an inside space that fits your box plus 3 inches of headroom, cut a side entry and high vents, seal every cut edge, line the floor with a waterproof tray, and keep it freestanding with a furniture-to-furniture strap. Nothing touches the rental itself.
An IKEA cabinet is the classic litter box hack because it's cheap, sized right and easy to cut. In a rental, the challenge is doing it without drilling walls, staining floors or leaving smells behind when you move.
This step-by-step covers the conversion for renters. For ventilation in depth, see the litter enclosure DIY with real ventilation, and for style ideas, litter box furniture that hides it in plain sight.
Choosing the cabinet
Measure your litter box first: length, width and height with the rim. The cabinet's inside space needs to be bigger in every direction, with at least 3 inches above the rim so your cat can stand and dig. For many large boxes, that means a sideboard or TV bench at least 20 inches deep and 18 inches tall inside.
Pick a cabinet with a solid back and sides; open-backed units leak litter and smell. A removable shelf helps, because you'll take the middle shelf out. Doors that open fully make scooping easy.
Planning the layout
- Entry on a side panel, not the front door, so litter drops off paws on the turn.
- Box on the opposite side from the entry, with a landing space between.
- Two vents high on the back or sides.
- Door opening toward you for scooping.
Sketch it on paper with measurements before cutting. Mark where the internal frame or cam locks are, so you don't cut through them.
Why renters need a different approach
Most IKEA litter hacks assume you can fix the cabinet to the wall, run a duct outside or replace the flooring if something goes wrong. A renter can do none of those. The plan has to protect walls and floors, keep smells inside the cabinet rather than in the carpet, and come apart cleanly when the lease ends.
The good news is that a well-sealed freestanding cabinet does all of this. The key decisions are the cabinet size, sealing every cut, and a floor protection layer under the whole unit.
Cutting the entry
An entry hole of about 7 to 8 inches across suits most cats; large cats may need 9 inches. Draw the circle or rounded rectangle, drill a starter hole in a corner, and cut with a jigsaw. No jigsaw? A hand keyhole saw works on particleboard, just slower. Keep the bottom of the hole at least 4 inches above the cabinet floor so litter stays in.
Tools you need
| Tool | Use | Renter-friendly alternative |
|---|---|---|
| Jigsaw | Entry and vents | Keyhole saw |
| Drill | Starter holes | Bradawl and hand drill |
| Sandpaper, 120 grit | Smooth edges | Sanding block |
| Brush | Sealer | Foam brush |
| Tape measure and pencil | Marking | - |
| Dust mask | Cutting particleboard | - |
Cut outdoors or on a balcony if you can, and vacuum dust straight away. Particleboard dust is fine and spreads.
Front entry or side entry?
A side entry hides the hole from view and gives your cat a turn before it exits, which drops more litter inside. A front entry is easier if the cabinet sits in a corner with one side against a wall. If you choose the front, cut it in a door panel rather than the fixed frame, so you can swap the door back to an uncut one when you sell or reuse the cabinet.
That door-swap trick is useful for renters: buy a spare door, cut that one, and keep the original in storage.
Sealing every cut
IKEA cabinets are mostly particleboard with a thin surface layer. Cut edges absorb moisture and swell, which ruins the cabinet and holds smells. Sand edges smooth, then seal them with two coats of water-based polyurethane or edge tape. Seal the inside floor and lower sides the same way.
An unsealed edge near the box can swell within weeks if urine reaches it.
Protecting your floor
Litter and urine reaching the floor under a cabinet is how renters lose deposits. Put a waterproof mat under the whole cabinet, slightly larger than its footprint. On carpet, use a hard chair mat. Lift the cabinet every few months to check the floor and clean underneath.
Felt pads on the cabinet feet prevent scratches on wooden floors when you pull it out to clean.
Choosing the right litter box for the cabinet
An open, high-sided box suits most enclosures; a lidded box inside a cabinet doubles the enclosure and traps more smell. If your cat sprays or digs hard, a box with high sides and a lower entry lip works well. Measure the box with its rim and any scoop clearance before buying the cabinet.
Litter type matters too. Low-dust, unscented clumping litter keeps the enclosure cleaner and is easier on your cat's nose in a closed space.
Waterproofing the floor
Put a plastic tray, a boot tray or a cut piece of vinyl flooring with turned-up edges under the box. It catches overspray and spilled litter. Seal the seam where the floor meets the sides with clear silicone for extra protection. Clean the tray weekly.
Ventilation without wall fixings
Cut two vents high on the back or sides and cover them with mesh. Leave a 2-inch gap between the cabinet back and the wall. If smell builds up, add a small USB fan behind one vent, powered from an adapter. The carbon filter DIY for litter furniture explains adding a filter over the exhaust.
Signs something isn't working
- Your cat hesitates at the entry or goes elsewhere: the space may be too tight or smell too strong.
- A smell when you open the door: scoop more often or add a fan.
- Swelling or soft spots on edges: a seal has failed; re-sand and re-seal.
- Litter on the floor outside: add mats or raise the entry.
Fix problems quickly. A cat that starts avoiding the box can develop a habit that's hard to reverse.
Anti-tip without drilling
Tall IKEA units come with wall anchors, but low sideboards are much less tip-prone. Keep the enclosure low and wide. If it's taller or sits on carpet, strap it to a heavier piece of furniture beside it rather than the wall, or use a weighted shelf inside. The CPSC Anchor It campaign explains tip-over risks.
Never stack anything heavy on top of a converted cabinet.
Tracking control at the entry
Put a litter mat outside the entry, and a smaller textured mat inside, between the entry and the box. Your cat steps over both on the way out. Litter tracking solutions compares mat types.
Introducing your cat
Leave the door open for the first week so your cat sees the box inside. Keep the same litter and box. Add a few treats near the entry. ASPCA guidance on litter box problems covers why cats might avoid a new setup.
Moving out with it
Empty the box and tray, wipe and air the cabinet, and lift it off the waterproof mat. Clean and dry the floor, take photos, and you're done. The cabinet goes with you, ready for the next home. Turning an IKEA cabinet into a litter enclosure has more design variations.
Cleaning and odour
Scoop daily and wipe inside weekly. The cleaning routine for DIY enclosures and apartment litter odour fixes go deeper.
IKEA cabinet litter enclosure for renters: FAQs
Which IKEA cabinets fit a litter box?
Look for low sideboards or TV benches at least 20 inches deep. Measure your litter box and check that the interior is longer and wider than it, with about 3 inches of headroom above your cat when it squats. Models with a thin, removable back panel are easiest to vent without touching the rented walls.
How big should the entry hole be?
An opening around 7 to 8 inches across suits most cats; large breeds such as Maine Coons usually need about 9 inches. Keep the bottom edge a few inches above the cabinet floor to hold litter in, round off the corners, and sand the cut smooth so fur does not snag on rough particleboard.
How do I stop particleboard swelling?
Raw particleboard edges soak up moisture and puff up. After cutting, sand each edge, then brush water-based polyurethane over the cut edges and the whole interior floor, letting every coat dry fully before the next. Set the litter box in a waterproof tray as a second barrier, and wipe up spills as soon as you see them.
Do I need to anchor it to the wall?
A low, wide sideboard is far less likely to tip than a tall unit, especially with a heavy litter box sitting inside. If you have climbing cats or small children, link it to a neighbouring piece of furniture with anti-tip straps instead of drilling into the wall, so the lease stays intact and the cabinet stays put.
Will I lose my deposit?
The enclosure itself should not cost you anything, since it stands freely and nothing is fixed to walls or floors. What landlords notice is the floor underneath. Use a waterproof liner, felt pads and a mat at the entrance, and before moving out, lift the cabinet, clean the floor beneath it and treat any stains.
Can I use a lidded box inside the cabinet?
It is usually better not to. A hooded box inside a cabinet is a box within a box: it cuts headroom and holds ammonia close to your cat's nose. An open box with high sides gives more space, lets air move toward the vents and still contains kicked litter, because the cabinet walls already act as the hood.
How often should I re-seal the inside?
Lift out the box and inspect the cut edges and floor every few months. If a spot feels soft, looks raised or smells, let it dry completely, sand back to firm board and apply fresh water-based polyurethane before the box goes back in. Catching swelling early stops the floor panel from crumbling and staining the floor below.
Can two cats share one cabinet enclosure?
They can, but most cats do better with one box per cat plus one. A single cabinet counts as one place, so a second cat may be blocked or ambushed at the entry. Treat the cabinet as one toilet and put another box in a different room, which matters even more in a small rental with few hiding spots.
