I’ve finally got my act together and I’m sharing some of my DIY Under the Kitchen Sink Storage Ideas!

Step-by-step Tutorial for DIY Under the Sink Storage Ideas

Here’s what it looked like under my sink before I got this space organized with dollar store supplies. It wasn’t filthy, but it was cluttered and unorganized.

I cleaned out everything under the sink and then I used a dollar store under-the-sink mat, which I measured and cut down to size so it fit under the sink space.

Car Seat Organizer Hack

Once I had that mat down, the first thing I wanted to do was organize some of the little things in this space. I actually found this car seat organizer at the dollar store and I thought it would be the perfect hack for this space.

I cut off any excess pieces (like the straps) and knew that I could use the pockets to hold all of the loose things under the sink, like extra sponges, bags, etc.

I got a drill and some screws and drilled right through the felt car piece into the side of the cupboard so that I could hold everything upright and take up as little space as possible under the sink.

I used the Kleenex part of the mat to hold all of our plastic bags, nice and snug.

Garbage Bag Roll Holder

I love the idea of having the garbage more accessible than in the box, so I bought an over-the-door storage basket from the dollar store

I didn’t like the look of having hooks hanging over the kitchen cupboard door, so I had to find a way to engineer something so it hung inside the cupboard.

For this kitchen sink storage DIY, I decided to buy a plunger and take the rubber part off the bottom and then to buy some hooks from the dollar store that I could use to hang that wooden plunger up. The hooks weren’t quite wide enough for the wooden dowel, so you can use pliers or vice grips to stretch the hook open a little bit, so that the dowel sits in it nicely.

Once your hooks are ready, you can put them into the side of the cabinet. Put the dowel right into the hooks and hang your basket on the dowel.

You can cut your dowel down to size, but ours was just gonna be sticking into the back of the cabinet, so we left it the same size.

Dollar Store Baskets

Finally, I used some dollar store baskets to organize all of the vases and things that I reach for less often in the back.

And then all of the cleaning supplies, and things I reach for more frequently, in the front.

These are more dollar store hacks than DIYs, but I’m really happy with how organized this space feels now, after only spending a few dollars at the dollar store. The car mat is so functional in here, I love how it stores everything. And honestly, the space just finally looks nice.

There’s lots of extra space if I have to put any of those Costco sized containers back in for storage, but I’m really happy with how accessible all these bags are now and I’m happy that they’re not hanging on my door.
