The Drawer Liner Alternative That'll Waterproof Under-Sink Cabinets In A Pinch

Protecting under-sink cabinets is a must if yours are made from a material like hardwood or MDF that is easily ruined by excess moisture, one of the ways you could be damaging your cabinets without noticing. Waterproofing is one of the best ways to ensure they stay pristine, but sometimes potential damage can occur before you're prepared. Whether a leaky pipe or product spill, it's important to find a solution that prevents moisture from accumulating under your sink. Though there are a few ways to waterproof under-sink cabinets, flexible plastic cutting boards serve as an excellent alternative that protects your space without much effort whenever you're in a pinch.

Flexible plastic cutting boards are great because they're waterproof and offer heavy-duty protection, making them the ideal solution until you can get something more permanent. Though plastic cutting boards don't necessarily protect your kitchen cabinets from mold or mildew, you likely already have these common household items. When an emergency happens and you need a quick fix, these are the perfect way to help save the space under your sink from water damage.

Be sure to measure your under-sink cabinet space and position the cutting boards in a way that fits the area. A common size for flexible plastic cutting boards is around 15 inches long and 12 inches wide, and standard kitchen cabinets below a sink range in size from 30 to 36 inches wide and around 24 inches deep. If your cabinets are a standard 30 inches wide and 24 inches deep, four 15-by-12-inch flexible plastic cutting boards should cover the bottom of your cabinet. However, if you have wider cabinets, you might need to overlap or cut additional boards with scissors or a utility knife to fit the extra inches of space. From there, simply arrange the cutting boards on the base of the cabinet. 

For a more long-term solution to keep moisture out of your cabinets, you should use shelf liners in your kitchen cabinets like an under-sink cabinet mat. Under-sink mats are made from sturdy waterproof materials such as silicone and are usually textured, so any items that live on top of the mats won't slide around. They often have a raised edge that keeps any accidental spills or leaks from overflowing or soaking into the sides of the cabinet. Plus, they can be budget-friendly and come in various sizes to fit your space perfectly. Additionally, cabinet mats can be easily cleaned up and don't require a lot of preparation or attention after adding them under your sink.
