Start by assessing mounting surface, lock type, capacity, and material. For tile or concrete walls, choose a sturdy surface-mount model; consider recessed options for a sleek look. Ensure the keyed lock fits your building's keying system and that spare keys are easy to manage. Check that the holder accommodates standard toilet paper rolls and matches the restroom’s durability requirements.

The locking mechanism is the most complex attribute, so evaluate its security and reliability. Compare cam-lock vs. pin-tumbler styles and look for anti-pick features, weather resistance if outside, and easy rekeying. Ensure the keyway is protected from moisture and that keys are easy to duplicate through your facility's approved supplier. Choose a finish that resists corrosion so the lock remains functional in a humid restroom.

In high-traffic facilities, prioritize durability, secure keying, and easy maintenance. For small or low-turnover spaces, a simpler keyed option with clean aesthetics and straightforward key management may suffice. Consider installation location to minimize vandalism and ensure accessibility per local guidelines.

Mount the holder securely using appropriate fasteners for your wall type and ensure it fits standard tissue rolls. Use wall anchors for drywall or tile and verify the screw placement matches the punch-out holes on the unit. Clean with non-abrasive cleaners and avoid harsh chemicals that can corrode finishes. Regularly check the lock and key for ease of use and replace if wear is evident.

Look for trusted brands and stainless steel series that are designed for commercial bathrooms. Brands like Häfele and National Hardware offer keyed locking options in their commercial bathroom hardware lines. Choose a durable finish such as brushed stainless steel to withstand moisture and heavy use.
