You’re running late in the morning and can’t find your face wash, which makes you feel stressed – what a bad way to start the day!

Your under-sink cabinet is a convenient place to keep important items you need in the bathroom. The under-sink cabinet is also useful in your kitchen, where it can keep various supplies in a safe and convenient way.

How do you organise your under-sink cabinets? You should keep these cabinets uncluttered by investing in bins, baskets, and rods to help you ensure that everything that’s stored in them is easy to spot when you need it.

With that in mind, let’s see how you should organise your under-sink cabinet in the kitchen and bathroom.

We’ll start with some general tips.

How To Organise Your Under-Sink Cabinets

Whether you’re organising the cabinet underneath your sink in the bathroom or in the kitchen, there are some general tips you can consider to keep your items within reach and easy to find, while preventing clutter.

  • Make use of clear bins. See-through bins are great for keeping cleaning and other items organised because they will make it easy to see them immediately when you open the cabinet doors.
  • Install a tension rod. This rod will run across the top of the cabinet and it comes in very useful to increase your storage space. You can use this to hang clothes, hang a pouch containing pegs, or prop your detergent bottles. Pro tip: you can easily store your detergent spray bottles on this rod by slotting their heads onto them – you’ll see how the heads are designed makes it easy to hang them on a bar or rod.
  • Set up compartments. If you have different types of items in your cabinet, you should designate different areas for them. For example, in the kitchen under-sink cabinet, you could have items such as cleaning products and tools, and having them in different areas of the cabinet will help to keep them organised. To make it even easier to group items together, put them on trays of different colours.
  • Place a mat on the bottom of the cabinet. If you don’t have a spare mat, use an old towel. This will prevent damage to the cabinet if there’s a leak and will also prevent mould from forming. Remember, both the kitchen and bathroom can be very humid areas in the house!
  • Use small storage racks. These are perfect for keeping different items together in a convenient place. For example, in the bathroom, you could keep body wash products on the top rack and teeth-cleaning products on the second. If you have an old shower rack you no longer use, it’s perfect for under-cabinet storage. You could even attach it to the inside of the cabinet door to maximise your storage space.
  • Make use of the doors. Speaking of the inside of your cabinet doors, putting simple hooks on them can make them a handy place to store kitchen or bathroom cleaning cloths, rags, and other items that can end up in a messy pile.
  • Set up some shelves. If you have shelves in the under-sink cabinet, you can make them easier to work with by ensuring that the items you use the least are at the back of the shelf, while the daily items are at the front. This will save you so much time.
  • Holders, even if they’re old plastic drinking glasses you no longer use, can be great for items that can cause clutter. These include brushes and combs in the bathroom and cleaning brushes or dusters in the kitchen.
  • No shelves? Make use of baskets. Not only do these look good but you can use them to increase your organisation by labelling them on the front so you know where everything is at all times.

Since this cabinet is right underneath your sink, it makes sense to use it to store your cleaning products.

Here’s an example of some items you should have in this space:

  • Detergent bottles (such as floor cleaner, dishwashing liquid, and others)
  • Kitchen sponges
  • Cleaning brushes
  • Cloths
  • Dustpan and brush
  • Refuse bags
  • Hand-held vacuum
  • Bag of laundry pegs

What you shouldn’t keep in this cabinet:

  • Strong chemical cleaners. For starters, they’re in easy access to children, which makes them very unsafe. You should actually store these toxic cleaning products in the garage or basement so that they’re not dangerous and kept away from other items.
  • Flammable products. If you have polishes, solvents, or flammable cleaners, they pose a risk of spontaneous combustion. One of the most dangerous is oily rags after they’ve been used to apply polish to furniture, especially if the polish contains linseed oil or flaxseed oil. Keep them out of the kitchen because it’s so much safer to do so.

How To Organise Your Under-Sink Bathroom Cabinet

This cabinet in the bathroom is great for storing items that you don’t have space for in the wall cabinets, but it’s crucial to be careful with clutter as you won’t have much space in your bathroom, especially if it’s small.

Here are some things you should store in the under-sink bathroom cabinet:

  • While you might have items such as toothpaste, mouth wash, face wash, moisturiser, and others in your wall cabinet, you can store them underneath your sink too. You can also store extra supplies of these so that you have them when you need them but they’re out of the way.
  • Hairstyling tools. Since you want to style your hair in front of the bathroom mirror, it makes sense to store your hair tools underneath the sink. A good way to prevent them from causing clutter is to hook them to the inside of the cabinet door so that they’re out of the way, especially because their wires can become messy.
  • Toilet paper. To prevent toilet paper from being stored out in the open, you can store it underneath the bathroom sink. It’s much neater and you won’t have unsightly bulk packs of toilet paper all over the bathroom.
  • Beauty products. It makes sense to store your beauty products in the bathroom. Use separate baskets or shelves for skincare, makeup, and nail products, the latter of which would include items such as nail files, nail clippers, and nail polish. Under the sink is actually the best place to store these items because you don’t want to leave them on the vanity if it gets a lot of sun during the day.

What you shouldn’t keep in this cabinet:

  • While a first-aid kit is okay to store underneath the bathroom sink, avoid storing medications anywhere in the bathroom. This is because this is a room of the house that’s prone to high levels of humidity, which can damage your medication and make it less effective.
  • It might seem to make a lot of sense to store your towels in the bathroom, but these are prone to the high levels of humidity that are present in the bathroom, too. This can lead to your towels becoming a target for mould and mildew. Rather keep your towels in a different cupboard, such as in the bedroom or passage, and free up extra space for other bathroom items.
