A litter box is necessary, but leaving it out in the open can make even the most organized home feel messy. 

That’s why DIY litter box enclosures have become so popular—they hide the box, control odor, and blend seamlessly with your décor. 

Whether you live in a small apartment or a spacious home, the right enclosure can make a big difference. 

In this article, I will show you 26 creative DIY litter box enclosure ideas that are practical, space-saving, and easy to customize for your home.

Why Build a DIY Litter Box Enclosure?

A DIY litter box enclosure helps you keep your home clean and visually clutter-free while still giving your cat a comfortable, private space. 

By enclosing the litter box, you can reduce odor spread, limit litter tracking, and hide an everyday necessity inside functional furniture. 

DIY options also let you customize the size, style, and placement to fit your space perfectly—something store-bought enclosures often can’t offer.

Cabinet Conversion

Turn an old kitchen or storage cabinet into a clean, hidden litter box enclosure. Cut a side entry hole and add ventilation gaps at the back. The enclosed design keeps litter mess contained while blending seamlessly with home furniture. 

This works especially well in living rooms or hallways where you want the litter box completely out of sight.

Bench Enclosure

A bench-style enclosure hides the litter box while doubling as functional seating. Place the litter box inside, add a side entrance, and use a hinged or lift-top lid for easy cleaning. 

This idea works best in entryways or mudrooms where extra seating is useful and floor space is limited.

Side Table

Convert a small side table into a discreet litter box enclosure that fits next to sofas or beds. The top stays usable for décor while the inside hides the litter box neatly. 

A rear or side cut-out allows easy access for your cat, making this perfect for apartments or small rooms.

Vanity Hack

Use an unused bathroom vanity to create a moisture-resistant litter box enclosure. The cabinet structure naturally hides odors and mess, while plumbing cutouts can double as entry points. 

This setup works great in bathrooms or laundry areas where cleaning supplies are already nearby.

Laundry Cabinet

Turn a spare laundry room cabinet into a hidden litter box enclosure that keeps mess out of sight. Cut a side entry and add small ventilation holes at the back to control odor. 

This setup works well near washing machines, where cleaning supplies are already stored and tile floors make cleanup easy.

Besta Hack

Use an IKEA Besta unit to build a sleek, modern litter box enclosure. The flat surfaces make it easy to cut an entry hole while keeping a clean exterior look. 

This option fits well in contemporary homes and works best in living rooms or bedrooms where you want the litter box to blend with furniture.

Kallax Hack

Convert a single cube or side-facing Kallax unit into a compact litter box enclosure. The cube shape provides enough room for most litter boxes while keeping the design simple. 

This idea is ideal for small apartments where space is tight and furniture needs to serve more than one purpose.

Farmhouse Hutch

A farmhouse-style hutch creates a charming litter box enclosure with plenty of airflow. Use the lower cabinet for the litter box and keep the top section for décor or storage. 

This works well in kitchens or dining areas where rustic furniture already fits the overall style.

Console Table

Convert a narrow console table into a discreet litter box enclosure that fits well along hallway walls. The slim design keeps walkways clear while hiding the litter box inside. 

A side entry keeps the front looking clean, making this ideal for entryways or transitional spaces.

Corner Unit

A corner enclosure uses often-wasted space to hide the litter box neatly. Build a triangular or angled cabinet that fits snugly into corners without blocking movement. 

This idea works especially well in small rooms where every inch of floor space matters.

Double Stack

Create a vertical enclosure with two stacked litter box compartments for multi-cat homes. Each level has its own entry to reduce traffic issues. 

This design saves floor space while giving each cat a separate area, making it practical for apartments or shared living spaces.

Stair Storage

Use the space under stairs to build a custom litter box enclosure that stays completely hidden. 

The enclosed area helps control odors and mess while keeping the litter box out of main living areas. This option works best in homes with unused under-stair storage.

Entry Bench

Turn an entryway bench into a dual-purpose litter box enclosure. The interior hides the litter box, while the top works as seating or a drop zone. 

A side entrance keeps the design neat and practical, making this ideal for small foyers or mudrooms.

Nightstand Hide

Convert a bedroom nightstand into a discreet litter box enclosure that blends with existing furniture. 

The top remains usable for lamps or décor, while the litter box stays hidden inside. This works best for cats that prefer quiet, low-traffic areas.

Closet Build

Use unused closet space to create a fully hidden litter box enclosure. Install a low cabinet or framed opening to keep the litter contained while maintaining airflow. 

This solution is ideal for apartments where visible litter boxes are not an option.

Sliding Doors

Build a cabinet with sliding doors to conceal the litter box without needing extra clearance to open. Side or rear entry holes keep the exterior clean and modern. 

This idea works well in tight spaces where swing doors are inconvenient.

Pull-Out

Build a pull-out tray enclosure that lets the litter box slide out for easy cleaning. The outer cabinet keeps everything hidden while the inner tray reduces lifting and mess. 

This idea works especially well in kitchens or laundry rooms where cabinets are already installed.

Wall Mount

Create a wall-mounted litter box enclosure that lifts the box off the floor. This design frees up floor space and makes cleaning underneath easier. 

It works best for agile cats and modern interiors where floating furniture already fits the style.

Porch Box

Design a weather-protected enclosure for covered porches or balconies. Use treated wood and raised flooring to protect the litter from moisture. 

This option keeps litter smells outside while still giving cats easy access from indoor spaces.

Simple Cover

Build a basic box-style cover that sits directly over the litter tray. This minimal design hides mess without taking up much space and is perfect for beginners. 

It works well in bathrooms or laundry rooms where function matters more than furniture style.

Rustic Crate

Use wooden crates to build a rustic-style litter box enclosure with natural airflow. Stack or enclose the crates around the litter box while leaving a side opening for entry. 

This idea works well in farmhouse or boho interiors where imperfect wood textures feel intentional.

Midcentury Cabinet

Repurpose a mid-century–style cabinet into a sleek litter box enclosure. The low profile and tapered legs keep the piece airy while hiding the litter box inside. 

This design fits well in living rooms or bedrooms where style matters just as much as function.

Ottoman Box

Turn a storage ottoman into a hidden litter box enclosure that blends with seating furniture. The soft exterior keeps the look cozy while the interior conceals the litter box. 

A side cut-out ensures easy access, making this ideal for small living spaces.

TV Stand

Convert a TV stand or media console into a wide litter box enclosure. The extra width allows better airflow and space for larger litter boxes. 

This idea works best in living rooms where long furniture pieces already sit against the wall.

Floating Shelf

Build a floating shelf enclosure that hides the litter box inside a raised cabinet. The elevated design keeps the area below open and makes floor cleaning easier. 

This idea works best for confident cats and modern homes where wall-mounted furniture is already used.

Reclaimed Build

Use reclaimed wood to create a custom litter box enclosure with a unique, eco-friendly look. 

Each build can be sized to fit your space exactly, making it ideal for awkward corners or unused walls. This approach adds character while keeping the litter box fully hidden.
