DIY Litter Box Enclosure: How to Hide a Litter Box in a Cabinet

A DIY litter box enclosure is a cabinet, sideboard, or storage bench you convert to hide the box: cut an entry hole in one side, add ventilation, protect the inside from moisture, and keep a door you can open for scooping. Many owners start with a basic cabinet from IKEA or any furniture store. The key is choosing a piece with enough room inside for your box and your cat, then sealing it so urine and litter never reach bare wood.

This guide is general product information, not veterinary advice. If your cat’s litter box habits change, such as straining, going outside the box, or producing much more or less urine than usual, contact your veterinarian.

Below you will find how to pick the right cabinet, a step-by-step build, how to keep it dry and fresh, and when buying a ready-made enclosure makes more sense.

Choose a Cabinet That Fits the Box and the Cat

Measure your litter box first, then measure the inside of the cabinet, not the outside. Shelves, back panels, and door frames all eat into space. You want room on every side of the box so you can slide it in and out, and enough height for your cat to stand, turn, and dig without hitting the top.

A common rule of thumb is to leave a few extra inches beyond the box on each side and above your cat’s head when it stands. Large cats and cats that stand while they pee need more height. If the cabinet has a fixed middle shelf, plan to remove it or choose another piece. Solid wood and well-sealed engineered wood both work; unsealed particleboard is the weak point, since it swells when it gets wet.

Step by Step: Build Your DIY Litter Box Enclosure

1. Pick the entry side. Choose the side that faces open floor, not a wall, and keep the hole low enough that your cat can step in rather than jump.
2. Draw the opening. Trace a template on paper first, larger than your cat’s shoulders, and tape it to the panel. Round shapes are easiest for cats to use.
3. Cut the hole. Drill a starter hole inside the line, then cut with a jigsaw. Wear safety glasses and a dust mask, and work away from your cat.
4. Sand the edges smooth so nothing can snag fur or paws, then seal the cut edge, since raw edges soak up moisture first.
5. Add ventilation. Drill a few holes high on the back or the side opposite the entry so air can move and odor does not stay trapped.
6. Line the floor. Set a plastic tray, a cut-to-size plastic sheet, or a litter mat under the box to catch spills and protect the wood.
7. Keep a scooping door. Use the cabinet’s existing door, or add hinges so you can reach the box without moving it.

If you paint or seal the inside, use a product made for the material and let the cabinet dry and air out fully, away from your cat, before the box goes in. Strong fumes can put a cat off the new spot.

Keep It Dry, Clean, and Fresh

An enclosure hides the box, but it also hides the mess. Scoop daily, wipe the floor liner weekly, and pull the box out for a full clean on the same schedule you used before. A cat litter mat outside the entry catches litter from paws before it spreads across the floor.

Ventilation holes help, but they do not replace cleaning. If odor builds up, look at the box and litter first. A litter box built for odor control or a covered litter box inside the cabinet can contain more smell and scatter.

Help Your Cat Adjust

Some cats walk right in; others need time. Start with the door open and the box partly visible, keep the same litter, and put a little used litter in the new box so it smells familiar. Older cats and big cats need a low, wide entry, and a low-entry box for senior cats works well inside a cabinet.

If your cat stops using the box after the move and also strains, goes often with little result, or has blood in the urine, call your veterinarian rather than assuming it is about the new cabinet.

When to Buy a Ready-Made Enclosure Instead

A DIY build makes sense if you already own a suitable cabinet or want a piece that matches your furniture. Buying ready-made makes more sense if you do not have tools, rent and cannot drill, or need a cabinet sized for a very large box. Ready-made enclosures usually come with the entry, vents, and a waterproof finish already in place.

Frequently Asked Questions

How do you make a litter box enclosure from an IKEA cabinet?

Pick a cabinet with enough room inside for your box, remove any fixed shelf, cut and sand an entry hole on one side, add vent holes, line the floor with plastic, and keep a door for scooping.

How big should the entry hole be?

Wider than your cat’s shoulders and tall enough that it can walk through without crouching hard. Trace a paper template and hold it up to your cat before you cut.

How do I hide a litter box without a cabinet?

A covered or top-entry box, a folding screen, or a spot behind furniture with clear access can all work. Keep the box easy for your cat to reach and easy for you to scoop.

Will a litter box enclosure smell?

It can if it is not ventilated or cleaned often. Add vent holes, line the floor, and keep scooping daily.
