I AM SO HAPPY I FOUND YOUR CHANNEL! You should have millions of views per video! Your videos are so easy to follow!

Wow, thank you!

Unfortunately with the waterproof sheet just lying on top of the cabinet bottom, if you do get a leak or a large spill, the liquid will likely get pulled between the mat and the cabinet bottom by surface tension from around the edges (particularly at the back and sides). The mat may make it harder to notice the water underneath and will impede drying, likely causing more damage. What would be more effective would be a shallow-lipped pan. I've even considered using waterproofing paint or epoxy to waterproof the bottom and lower sides of the cabinet.

Yes, you're totally right. For standard kitchen sink cabinets, you can buy rubber mats that have a lip around the outside and will contain a lot more. I put one of those in my kitchen. They're harder to find for bathrooms because there are so many sizes.

@@MomCanFixIt - Why is it not surprising that you have already researched this so well? 🙂 You really are a great resource. Keep up the great videos!

You can add clear silicone caulk around the edge.

[@123Rockchild]

Great idea.

[@MomCanFixIt]

Thanks!

[@Enigma758]

Good idea, but I think it would be better if there were some upright edges to form a shallow "tub".

[@MomCanFixIt]

The one I got for my kitchen sink does have raised edges. The problem is that bathroom cabinets are not a standard size so it's hard to get a standard-size mat. For kitchen sink cabinets there are really only 2 sizes so you can get ones the exact size.

[@Enigma758]

@@MomCanFixIt I know what you mean. Minimally, I am going to run a bead of silicone caulk around the inside edges since that is one of the biggest problems. Water leaks in and soaks into the end grain and the wood deforms/bubbles there.

We were storing emergency water under one sink and the plastic bottles leaked. Under the kitchen sink we had a valve fail -- and the "wood" go to mush... then the same valve went again after my husband used drain cleaner -- our handyman put in a new plywood base under the kitchen sink and we lined it with contact paper but I much prefer your solution!

[@MomCanFixIt]

Oh boy, that sounds stressful! We had a plywood bottom replacement under our kitchen sink in our first house. I wish I would have know there were options to make it nicer!

[@drmamu7777]

had the same problem. painted it with water proof paint used for roofs

[@MomCanFixIt]

Oh that's a clever solution!

[@babayaga5017]

im looking for effective methods for protecting under sink cabinets from moisture. I've found mats on Amazon that see more durable and have a lip that will retain the water. Also, I plan to put a container of damp rid under each sink to absorb moisture.

[@MomCanFixIt]

The mats with the lip are generally available in kitchen cabinet sizes (because there are really only 2 kitchen sink sizes) but they're hard to find to fit a bathroom cabinet properly. Make sure you also have good bathroom ventilation in generally (good exhaust fan if possible).

[@thesundancekid1974]

Oh yeah I've done better than that I swear why don't I think of this stuff. Where doing the 50 gallon aquarium with water back-in-the-day League somehow and the bottom of the two cabinets were fully submerged I sucked it up or dried it up or side to get up or something in just kept it to myself I guess I got it up quick enough and it didn't do anything that was noticeably damaged how to fix a crack in the bottom of the sink to that was another one that's still present

[@terry7893]

What a total waste of time. How is it waterproof, if water is just going to run off of it? You need sides to catch and hold any water otherwise it's useless.

[@franzgamerz6358]

Thats Bad ideas. Its better to paint it waterproof paint
