One size turned out to be the clear winner for a standard kitchen cabinet, and the smallest size surprised me most.

Why Jin Bao Under Sink Mat Is Necessary
Under sink mats matter because a slow leak can ruin a cabinet long before you notice it, and by the time the wood swells the damage is expensive to fix. A good mat catches drips, contains spills, and gives you a waterproof barrier between your plumbing and your cabinetry. In my testing, the mats paid for themselves the first time a bottle leaked, and the cabinet underneath stayed completely dry.
The right mat also makes the space easier to live with. Bottles stop sliding around, the surface wipes clean in seconds, and the raised edge turns a potential flood into a small puddle you can mop up. A silicone mat that survives the dishwasher is one you will actually clean, which keeps the cabinet fresh instead of musty.
Finally, a mat that fits properly is worth measuring for. A mat that is too small leaves gaps where water finds wood, and one that is too big curls at the edges and traps dirt. Fifteen sizes exist for a reason, and taking two minutes with a tape measure is the difference between real protection and a false sense of security.
My Buying Guides on Jin Bao Under Sink Mat
Why I Looked for Jin Bao Under Sink Mat
I found a slow leak under my kitchen sink and the cabinet floor was already swelling, so I went looking for a waterproof mat that would catch drips before they reached the wood.
My shortlist had to fit my cabinet exactly, have a raised edge to contain spills, and survive the dishwasher so I could actually keep it clean.
What I Check Before Buying
First I measure the inside of the cabinet, because a mat that is too small leaves gaps and one that is too big curls at the edges. Then I check the raised edge height.
I also read recent buyer comments about slipping and curling, since a mat that moves around or lifts at the corners is not protecting anything.
My Preference for Silicone or Fabric Mats
For under sink protection I prefer silicone, because it is fully waterproof, wipes clean, and never stays damp the way a fabric mat does. My results were best with thick silicone.
I still use fabric shelf liners in dry cupboards, where grip matters more than waterproofing and a soft surface protects dishes from chips.
What I Look for in Quality
A quality mat lays flat on day one and stays flat, with a raised edge high enough to hold a real spill. I test this by pouring a glass of water on it before I trust it.
I also look for one piece molding with no seams, because seams are where water sneaks through and where grime collects over time.
How I Compare Prices
I compare cost per cabinet protected, not the sticker on one mat. A mat that saves a single cabinet from water damage has paid for itself many times over.
I also factor in versatility. A mat that can double as a pet mat, a tray, or a shelf liner earns its keep even in a cabinet that never leaks.
My Tips for Choosing the Right One
Measure twice and buy the size that fits your cabinet with a small gap at the edges, so water cannot wick around the mat and the mat can be lifted out easily.
Check under the mat every month for trapped moisture, wipe it down often, and replace it if the edge ever cracks. A mat only works if you keep it clean and in place.
Final Thoughts
After three weeks of testing under sinks, in bathrooms, and around the house, Jin&Bao Under Sink Mat 34" x 22" Waterproof Silicone Cabinet Kitchen Liner is still the mat I would buy first, because it fit my kitchen cabinet perfectly, caught a real leak, and cleaned up like new. The 19 inch squares won on versatility, and the 34 by 22 multipurpose mat earned its keep in three different rooms.
My advice is simple: measure your cabinet, buy the size that fits, and put the mat in before the next leak rather than after it. Used that way, any of these five will protect your cabinets for years, and you will forget the mat is even there until the day it saves your wood.
