If you live in the UK, chances are your kitchen or bathroom cupboards are tight on space — and that awkward U-bend doesn’t make things easier.
But with a few smart under-sink storage ideas, you can turn that messy cupboard into a clean, organised space that actually works for you.
Here are ten clever, affordable ways to reclaim your cupboard space and keep everything tidy — even in the smallest flat or home.

1. Use Two-Tier Sliding Organisers
Sliding or pull-out organisers instantly double your usable space.
They make it easy to reach cleaning sprays, sponges, and cloths without knocking everything over.
Look for models with smooth runners and removable trays — they’re easier to clean and perfect for storing heavier bottles.
2. Stack Baskets Vertically
If you can’t go wider, go higher.
Stackable baskets or crates make use of unused vertical space under the sink.
They fit neatly around the pipes and are ideal for storing cloths, dish tabs, or spare sponges.
Choose open-sided baskets so you can easily see what’s inside.
3. Try Adjustable Racks for Odd-Shaped Pipes
Adjustable under-sink shelves are lifesavers for cupboards with tricky U-bends or pipes running through the middle.
You can move or remove sections to create a perfect fit.
The DEKAVA organiser is a great example — flexible, lightweight, and ideal for both kitchen and bathroom cupboards.
4. Add Door-Mounted Holders
The inside of your cupboard door is valuable real estate!
Attach small hooks, adhesive trays, or a simple rail to hang brushes, gloves, or bin bags.
This keeps your main shelf clear and makes everyday items easier to grab.
5. Use Clear Containers for Easy Visibility
If you’ve ever bought a second bottle of cleaner because you “couldn’t find the first one”, clear containers are your friend.
They make it easy to see exactly what you have, saving money and space.
Label each one for cleaning, sponges, and refills — you’ll never lose track again.
6. Choose Rust-Resistant Materials
Humidity and metal don’t mix well under sinks.
If your cupboard gets damp, a plastic organiser such as the PurKeep 2-Pack Under Sink Storage is ideal — lightweight, easy to clean, and resistant to rust.
7. Add a Small Drawer Unit for Extras
Slim plastic drawer units fit beside the U-bend and are perfect for smaller items like bin bags, microfibre cloths, or scrub brushes.
They help keep daily-use items separate from those you only grab once a week.
8. Combine Hooks and Hanging Baskets
If your cupboard has a sturdy frame, add hanging baskets or S-hooks for extra storage.
You can hang small caddies for gloves, scourers, or spare sponges — and still keep your shelf free for bottles.
9. Keep a Mini Bin or Recycling Pot
A tiny bin or container for used cloths, packaging, or empty bottles keeps the area clean.
This simple habit prevents clutter from building up and keeps your organiser looking neat.
10. Upgrade to a Complete Under Sink Kit
If you’re ready to go all in, a complete two-tier organiser set can transform your space in minutes.
These kits often include sliding trays, hooks, and baskets — everything you need for a full cupboard makeover.
