This is a clever U-shaped slide out shelf made by Lynk Professional.

Instead of having to duck down and reach deep inside the small space of your bathroom cabinets, this convenient organizer slides out so everything is within easy reach.

It is 30-inches wide and 18-inches deep. So please carefully measure your cabinet opening and check the location of your sink pipes prior to ordering. It does have a wire bottom and small items may fall through, but you could easily put small baskets on here to prevent this. It kind of looks like it’s giving your plumbing a hug doesn’t it.

You can mount it to one side of the cabinet and still have enough space on the other side to store larger items.

This two-tiered sliding organizer from “Made Smart” has frosted plastic baskets and removable dividers to compartmentalize the baskets to suit your needs.

There are spots to label the drawers using a dry erase marker.

It doesn’t screw to the bottom of the cabinet: it just sits, so it is especially good for renters.

You could also put this on the counter to hold beauty products, hand towels, cotton swabs, and other similar items. (If you had enough counter space.)

5) Clear Acrylic Stackable Cosmetic Organizer Drawers (Audrey by STORi)

A lazy susan like this one made by Copco allows you to grab bottles of cleaners, hair products and other items from underneath your sink with ease.

Instead of trying to pluck out a bottle and hoping you don’t knock over everything else like bowling pins, you simply turn it until the bottle you want is in the front.

This one is popular on Amazon and it has a non-skid surface and slight rim to help keep items on it.

10) Lazy Susan with a raised edge

Similar idea to the lazy Susan mentioned above but this one has raised edges to further ensure things stay put.

A 2-tiered lazy Susan like this one (also made by Copco) gives you extra space to help tidy up under the sink. It is 12-inches wide.

The bottom shelf will allow you to store smaller items up to about 4.5 to 5-inches tall. So this bottom shelf would work well for bars of soap, cleaning sponges, and other “short” products.

12) Clear Apothecary Jars

Apothecary jars are a decorative bathroom storage idea

These clear acrylic apothecary jars make great holders for q-tips, cotton balls, makeup removal pads, hair ties, and other everyday items.

And besides that…they look really cool.

These are an especially popular choice for people that don’t have a medicine cabinet because they can store a variety of items.

13) Sliding Cabinet Organizer (3 drawer with solid top)

Sliding drawer organizer

This is similar to the other slide-out organizers I’ve already mentioned, but this one has a solid top.

So you can fill the 3 sliding drawers with items (mostly small items), and then set shampoo bottles, cleaning bottles, storage bins, etc… on the top shelf.

It can be a bit tricky to tell in the photo, but it is a fairly small unit: 10-inches wide, 13.5-inches high, and 16-inches deep.

14) Stackable Sliding Basket Organizer

This is a popular under sink organizer made by DecoBros. It has a solid wire-rack top and slide-out basket underneath. There is a chance small items could fall between the wires, but if you’re concerned about this you can use plastic bins or a small wicker basket to corral smaller items.

And the units are stackable if you have the room under your sink.

15) Acrylic Nail Polish Holder

An acrylic nail polish holder like this on by iDesign can be mounted inside the bathroom cabinet, or onto the back of the door.

It would also work well to hold other small items such as nail clippers, hair brushes, tubes of cream or perfumes.

16) Clear Stackable Storage Boxes

These clear plastic storage boxes by mDesign have removable lids so they can be stacked on top of each other.

I realize the photo shows it with food items (they make a great pantry storage idea), but you can use them under the sink too for toiletries, cosmetics, and other bathroom necessities.

17) Clear Plastic Organizer with 5 Compartments

The company STORi makes this cool 5-compartment organizer. It is an excellent way store creams and cosmetics under the bathroom sink.

Then when you need them, just lift up the whole clear bin and set in on your bathroom counter. Put away when you’re done. Easy.

It would be a great addition to the other organizers I’ve already mentioned (like the wire rack organizer by DecoBros in idea # 14).

18) Slide-out Removable Cleaning Caddy

This slide-out cabinet organizer by “Rev-A-Shelf” is cool because it doubles as a cleaning caddy. You can slide it off its rollers, hold it by the upper handle and bring it with you to tackle home cleaning chores.

Just make sure you measure under your sink to ensure it’ll fit.

A lot of people use this in their kitchen to hold their kitchen cleaning supplies, or in the laundry room, but it’s a great option for the bathroom too.

19) Bathroom Under Sink Organization Starter Kit from The Container Store

If you don’t want to order a bunch of items separately then you’ll like this bathroom sink storage starter kit from The Container Store.

It comes with a 2-tiered metal slide out organizer, the clear plastic tote (like a cleaning caddy), a large bin (right side of picture), and the over-the-door hanging cabinet organizer with two shelves.

And if you don’t want a particular item – such as the plastic bin – then you can say Quantity of zero at the checkout. Or if you want more of an item – say you want 2 hanging organizers – then you can add that too. Pretty cool.

A simple way to store extra toilet paper under the bathroom sink is to get a fabric storage bin like this one from mDesign and tuck it inside the cabinet.

It’ll only had a few rolls, but if you have a tiny bathroom, you probably have to store the majority of your toilet paper rolls in a different room anyway.

23) Hanging Small Pocket Organizer

Take a small pocket organizer like this and screw it onto the inside of your bathroom cabinet door.

You’ll probably have to cut off some of the pockets to fit your door. (You can probably find similar products at the dollar store.)

Of course you won’t be putting your phones inside the pockets, but they are a great place to store and organize small items like nail polish, makeup brushes, hair ties, and other smaller items.

You may be able to fit a blow dryer inside one of the pockets depending on the size of pockets you buy. (Just let it cool down before you put it into the plastic pocket.)
