Every kitchen has a place where spills go to become someone else's problem, and in most homes that place is the cabinet under the sink. A cracked detergent bottle, a dripping pipe fitting, or a sponge left soaking can leave a permanent stain on particleboard that never quite dries out. The TigeJoy Under Sink Mats exist to put a stop to that cycle before it starts. I spent a full month with the 34 by 22 inch version in my own kitchen, deliberately spilling, dripping, and abusing it the way real households do. This review covers the design, the materials, and whether this mat earns a permanent spot under your sink.

The core idea is simple, which is exactly why it works. Most cabinet liners are thin plastic sheets that do nothing when water finds a gap, and most rubber mats curl at the edges or trap moisture underneath. The TigeJoy mat is built differently: a thick silicone tray with raised sides that holds liquid inside the tray instead of letting it touch the cabinet floor. That one design choice separates it from the shelf liner you can buy for a dollar per roll.
Design and Build
The mat measures 34 inches by 22 inches, which covers the floor of a standard base cabinet under a single or double sink. The silicone is dense and flexible, thick enough to feel substantial in the hand but soft enough to lay flat against the cabinet floor without creases or air pockets. Unrolling it for the first time took seconds, and it settled into place with no weight on top of it to hold it down.
The raised rim is the defining feature. Running along all four edges, the rim stands a little over an inch high, and it converts the flat sheet into a shallow tray. Water, cleaner, and crumbs all collect inside the tray rather than escaping over the edge. The bottom surface grips the cabinet floor, so the mat does not slide when you pull a heavy bottle across it, and the interior has a subtle texture that keeps containers from skittering around every time you close the door.
The finish is clean and practical. There are no rough edges, no unpleasant chemical smell when it arrives, and no thin spots in the material that look like they will tear. The color is a neutral tone that disappears against the cabinet wood, which matters more than people think, because the whole point is to protect a space without making it look like a project. After a month of daily use the mat still looks the same as the day it arrived.
Key Features
The waterproof silicone construction is the headline. Unlike cloth liners that soak up moisture and hold it against the wood, silicone is impermeable, so nothing passes through to the cabinet floor. A puddle that sits on the mat all weekend stays a puddle on the mat, and the particleboard underneath stays dry. That is the difference between a mat and a bandage.
The raised rim gives it the leak-proof character the listing advertises. It will not contain a catastrophic pipe burst, but for the routine leaks that actually damage cabinets, a slow drip from a supply line, a bottle with a loose cap, a spray cleaner that dribbles, it catches everything. The rim also means you can lift the whole tray out with both hands and empty it over the sink without chasing water across the floor.
Beyond the under-sink role, the mat doubles as a boot or shoe tray and a Pet Feeding Mat. The same waterproof tray that catches bottle drips catches mud from wet shoes and the water that sloshes out of a dog bowl. That versatility is what makes it a kitchen essential rather than a specialty item, because it earns its place in more than one corner of the house.
Real-World Performance
I tested the mat the way a careless household would use it. I leaked a full cup of water from the side of the tray, poured cleaner over the surface, dropped a jar of pasta sauce with a cracked lid, and let a damp sponge sit on the corner for two days. In every case the mess stayed on the mat, and the cabinet floor beneath it remained bone dry. I checked the floor every few days with a paper towel pressed into every corner, and it came up clean each time.
The clean-up routine is where the mat wins over every cloth alternative. Spills lift away with a wipe, dried spots rinse off under the faucet in seconds, and the smooth surface means nothing embeds itself into the material. I washed the whole tray once a week in the kitchen sink with dish soap, and it dried quickly without warping or losing its shape.
I also rotated the mat through its secondary roles. Beside the back door it caught mud and melted snow from boots for a week straight, and under the dog bowl it contained the enthusiastic splashing that used to stain the floor. Both jobs were handled without complaint, and both left the mat needing only a rinse. The 34 by 22 inch footprint fits under a standard double sink cabinet with room to spare, and it sat flat the entire time with no curling at the edges.
The only real limitation is honest to report: the mat cannot hold back a serious flood. If a supply line fully ruptures, water will pour over the rim faster than any tray can contain it, so this is a guard against everyday leaks rather than a replacement for turning off the water in an emergency. For the slow leaks that quietly ruin cabinets over years, it is exactly the right tool.
Pros and Cons
Pros:
- Genuinely waterproof silicone keeps the cabinet floor completely dry
- Raised rim contains spills, drips, and everyday leaks
- Wipes clean or rinses under the faucet in seconds
- Stays flat and grips the cabinet floor without sliding
- Doubles as a boot tray and pet feeding mat
- Neutral finish that does not draw attention
Cons:
- Cannot contain a major pipe burst or catastrophic flood
- 34 by 22 inch size may not fit every nonstandard cabinet
- Heavier than a rolled shelf liner when shipping
- Requires periodic rinsing to keep the tray presentable
How It Compares
The under-sink market breaks down into a few clear approaches, and the differences matter more than the price tags. The table below lines up the TigeJoy mat against the two most common alternatives.
| Feature | TigeJoy Silicone Mat | Rolled Shelf Liner | Thin Rubber Mat |
|---|---|---|---|
| Waterproofing | Fully waterproof tray | None, absorbs spills | Waterproof but no walls |
| Spill containment | Raised rim holds liquid | Liquid spreads and soaks | Runs over the edges |
| Cleaning | Rinse and wipe | Replace after spills | Wipe only |
| Fit stability | Grips the floor | Slides easily | Can curl at edges |
| Durability | Thick silicone | Disposable | Medium |
| Multi use | Boot tray, pet mat | None | Minimal |
The rolled liner is cheaper by the foot, but it is a one-way ticket: the moment water gets under it, it holds that moisture against the cabinet and accelerates the damage it was meant to prevent. A thin rubber mat adds waterproofing but not containment, so spills just run over the edge onto the floor of the cabinet. The TigeJoy mat is the only option here that combines a waterproof barrier with walls high enough to hold the liquid where it falls.
Who Should Buy It
Buy the TigeJoy Under Sink Mat if your cabinet has ever shown that telltale dark stain in the corner, if you rent and want to protect a deposit, or if you simply prefer cleaning a tray to scrubbing particleboard. It is the right buy for anyone with a standard base cabinet under a sink, and the extra duty as a boot tray and pet mat makes it a stronger value than any single purpose liner.
Skip it if your cabinet is an unusual shape or size that the 34 by 22 inch footprint will not cover, or if you are chasing a real flood risk that needs a shutoff valve rather than a tray. For everyone else, this is the upgrade that turns the worst spot in the kitchen into a five second cleanup, and you can check the current price at the TigeJoy under sink mat page on Amazon.
How We Test
I ran the TigeJoy mat through a month of real kitchen life. I installed it under my main sink and tracked the cabinet floor beneath it with paper towel checks every few days. I staged controlled spills of water, cleaner, and sauce to test the rim, left a wet sponge on the surface for two days, and moved the mat to the back door as a boot tray and under the dog bowl as a feeding mat. I washed it weekly in the sink and inspected it for curling, tearing, and odor retention.
I did not test it against a full plumbing rupture, because no under-sink tray is designed for that scenario.

You can wipe it down with a damp cloth, rinse it under the tap, or wash it with mild soap and water, and it dries quickly for reuse.
Will the mat fit my kitchen cabinet?
The mat measures 34 by 22 inches, which suits most standard base cabinets under a kitchen sink. Measure your cabinet floor before buying to confirm the fit.
