A small bathroom can make litter tracking harder to manage because every inch of floor has a job. Choose a litter mat (paid link to Amazon) that catches granules while keeping the box, doorway, and the cat’s walking route easy to use.
Measure the clear floor around the box, protect the door swing, and choose a mat that lies flat and is simple to lift for cleaning. Keep the litter-box entrance unobstructed.
Measure the usable floor, not the whole room

Measure the open floor after accounting for the door swing, sink cabinet, and the space needed to reach the toilet or shower. A compact litter mat for a small bathroom might be narrower or shorter than a standard design, but it should still cover the cat’s first steps out of the box.
Keep a clear route to and from the litter box. Do not place a mat so it wedges the cat between the box and a wall or blocks a doorway. Ohio State’s Indoor Pet Initiative recommends accessible, comfortable litter-box placement; a small-space accessory should preserve that access.
Look for a low-profile edge that will not trip people or make the cat hesitate. A non-slip backing can help, but check that it does not trap moisture on tile or vinyl. If the floor gets damp, lift the mat and dry both sides.
Make cleanup easy in a tight space

In a small room, cleaning access matters as much as capture area. Choose a mat you can lift with one hand, shake into a bin, or rinse according to its care label. A washable cat litter mat may be easier to maintain than one that traps debris in deep layers you cannot reach.
Check the mat daily for loose granules, then clean underneath on a regular schedule. Keep litter and cleaning tools in a closed, nearby container so supplies do not crowd the walkway. Avoid fragranced cleaners or sudden room changes that could make the litter area less inviting.
If the cat starts missing or avoiding the box after you rearrange the bathroom, remove the mat and restore a familiar route. ASPCA guidance notes that litter-box problems can have medical as well as environmental causes. A new mat will not solve discomfort or illness, so contact a veterinarian about persistent changes.
Lift and clean the mat before it becomes a pile of tracked litter, and keep the box route clear after every bathroom cleanup. Recheck clearances when the door or nearby storage changes.

Safe use and next step
Measure the usable path: Open the bathroom door fully, stand where you normally service the litter box, and mark the cat's actual exit route. A mat that fits the floor may still catch under the door or leave too little room to enter the box. Favor a layout that preserves a clear approach and lets you lift the mat for cleaning without moving the box every time.
Check the cat's response: Leave the box in a quiet, accessible location and watch whether the cat crosses, hops over, or avoids the mat. If access becomes awkward, remove or resize the mat. Empty and dry it as directed, and inspect the floor below for dampness. A mat is optional; a clean, usable box is not. If litter-box behavior changes, address access and consult a veterinarian for possible health concerns.
