What to Put in Self Storage: 25 Items Taking Up Too Much Space

Decluttering | 17.04.25

Let’s be honest — no matter how much we organise, tidy, or “do a quick clear-out,” our homes still fill up with stuff we don’t really use. And if you’ve ever found yourself wondering what to put in self storage, you’re not alone. Whether it’s a treadmill turned clothes rail, a spare bed frame you might need someday, or boxes of baby clothes you’re saving “just in case” — it all takes up room. Before you know it, your loft is full, the garage is chaos, and your hallway resembles a car boot sale.

So, if you’re wondering what to put in self storage (instead of tripping over it every week), we’ve rounded up 25 of the most common — and surprisingly bulky — space-hoggers you can store away today.

🧳 Why Store It Instead of Tossing It?

Not everything unused is useless. Sometimes, it’s just not needed right now — but will be later. That’s where knowing what to put in self storage comes in; giving you a middle ground between clutter and regret. It’s like pressing pause on your belongings, without saying goodbye forever.

And with flexible, local storage solutions like Space Centre Self Storage, it’s easier and more affordable than you might think.

Deciding What to Put in Self Storage vs. What to Let Go

When choosing between the bin, the donation bag, and a storage unit, ask yourself:

  • Do I use this every month?
  • Do I actually have space for it at home?
  • Is this seasonal or situation-specific?
  • Would I be upset if it disappeared?
  • Would storage help me decide more clearly, over time?

If you answered yes, you’ve just figured out what to put in self storage first.

You’d be surprised how freeing it is to put something away for a while. Out of sight doesn’t have to mean out of mind — it can mean peace of mind.
