Customer Insights: Rated 4.4/5 from 236 reviews.
Really like the quality of this liner. We have pipes that come from the bottom so needed a cut-to-fit liner. Very easy to unfold, measure, and cut while still having a decent thickness. Excellent price!
Nice and large so you can cut to the exact size you need. Working perfect under our kitchen sink to keep it easy to clean.
A must have for under the sink. I have one under every sink and in the clothes hamper. Cleans spills and does not leak on the wood. I used a stapler to bring the side up and seal the area.
[This review was collected as part of a promotion.] I received the #Mainstays™ Under-the-Sink Liner - Black, 24 in. x 4 ft. to try from # Try-it sampling and I'm loving it. These sink liners are so very easy to cut to size an place under your sinks and I also cut a few for my silver were drawers an refrigerator shelf. There r so many applications for this product . You can place them in tool boxes makeup cases and even places mats for the table. Thay r super easy to clean an matain you will love these liners.
[This review was collected as part of a promotion.] This under-the-sink liner is perfect for what I needed. It's large enough to fully cover my sink area. I used the extra to line a few kitchen drawers. The plastic liner is sturdy and just the right thickness that it's pliable but nothing can rip through it.
[This review was collected as part of a promotion.] Received this black under the sink liner and like the heavy good quality plastic. Nice size and love that it's easy to cut to size. Which makes it so easy to get a project finished. Would like a lighter color as I found the black color hard to see the edges in the back, under the sink.
Material is fine only problem I had it that it comes folded and not rolled like shown in the picture so it has creases in it and will not lay flat
[This review was collected as part of a promotion.] I under estimated how large this was. I cut it to fit under my sink. It wasn’t hard to cut up but it doesn’t lay flat well, maybe over time it will. It is not meant to have a garbage can on it the more I pull my can out the more it gets pushed to the back-which is fine. I’ll just remove the part from under my can. It is easy to wipe and clean and definitely adds extra protection under my sink. Because it was larger then I thought I had extra and was able to line my bathroom drawers which is great because my husband’s beard oil spills constantly and the kids toothpaste is always everywhere. This under the sink liner isn’t something I would normally buy and after using it I don’t know that I would I purchase it in the future simply because it moves easily and doesn’t lay very flat.
This is a great mat, but the way it is packaged is ridiculous. Rather than being rolled up like most shelf/drawer liners would be, this product is folded up multiple times, sort of like a map would be. As a result, it has creases all over that will not go away, especially where to folds meet, former a sharp "corner." It is impossible to get to lay flat on the floor of the sink cabinet. I tried sandwiching it in an electic blanket for hours -- that did NOTHING. Tried warming the crease with a heat gun and flatting them out -- better, but the crease don't want to go away. Tried using an iron set to very low temperature. Nothing worked. Ended up having to glue it to the floor to make it lay flat, which should not be necessary for a product like this.
It has been delivered to the wrong house. I don't know where it is.
