Frequently Asked Questions
Can under-sink liners stop odors as well as leaks?
Yes — liners that contain liquids stop water from pooling on cabinet floors, which reduces musty odors. For odor control, choose a waterproof liner with good containment and wipe or remove the liner regularly to prevent trapped grime. Adding an absorbent odor neutralizer on top of the liner can help in shared spaces.
Which liner is easiest to clean during a fast back-to-school turnaround?
Silicone liners (like the GORILLA GRIP) are easiest — many are dishwasher-safe so you can quickly sanitize them between occupants. Thick plastic mats wipe clean well but may need more drying time; molded trays can be rinsed but are bulkier to remove.
How do I choose the right size if my sink plumbing comes through the cabinet floor?
Measure inside the cabinet and note the location of supply lines and the drain. Cut-to-fit mats like RESILIA can be trimmed around floor-mounted plumbing for a snug fit. Molded trays (XTREME MATS) are excellent if plumbing is side-entry; if your plumbing comes through the floor, verify compatibility or plan for minor trimming.
