Under Sink Mat Silicone Waterproof Cabinet Liner - Trimmable

In this review of the Under Sink Mat from Famous Dino, the bottom line is simple: this is a practical, low-effort way to protect under-sink cabinets from leaks and spills. It is best for homeowners or renters who want a flexible, waterproof liner that is easy to cut and install around pipes and disposals. The single biggest reason to buy is its combination of durable BPA-free silicone construction and a raised edge that can hold up to 1.5 gallons of water, giving extra time to notice and address leaks.

Key Features

• Premium material: Made from BPA-free silicone so the liner is safe for people and pets and resists stains and chemical damage.
• Trimmable design: The mat ships at 31 in by 22.5 in and can be cut down in width to 28 in or 22 in and in depth to 19 in or 14 in for a custom fit.
• Flexible and foldable: The silicone bends to fit around pipes and disposals and lies flat without the deformation common to rigid trays.
• High liquid capacity: Raised edges allow the liner to hold up to 1.5 gallons of water, helping protect cabinets during a leak.
• Multi-purpose use: Works as a cabinet liner, pet feeding mat, or disinfection surface for shoes and other utility tasks.

Who It's For

This mat is ideal for people with under-sink filtration systems, garbage disposals, visible plumbing, or stored wet cleaning supplies who want a straightforward way to prevent water damage. It is especially useful for renters or homeowners who need a non-invasive solution that can be trimmed to size and removed later without residue.

Those who should look elsewhere include buyers who require a rigid, molded drip tray with integrated channels or who need a product larger than the stated 31 in by 22.5 in maximum size. If you prefer built-in fastening or a custom molded plastic pan, a different product may be a better match.

Pros & Cons

Pros

• Easy to cut and install, fitting neatly around pipes and disposals for a tailored fit.

• Attractive appearance that can improve the look of the cabinet interior while providing protection.
• Multi-use functionality as a pet mat or disinfection surface beyond cabinet protection.

Cons

• Not a rigid molded tray, so it will not provide molded channels for directed drainage or permanent mounting.
