If you’ve ever stepped into a bathroom that hasn’t been updated since the 1970s, you’ve probably seen one of these. It’s what many people jokingly call a “mystery tube,” often recognized as a 1970s-style bathroom bag holder. Surprisingly, that awkward-looking relic was actually a practical idea that turned out to be pretty clever.

It’s More Than Just a Plastic Bag Holder (Though It Definitely Does That)
At its core, it’s a plastic bag holder. You stuff bags in from the top, pull them out from one of the openings, and suddenly you’ve got a simple dispenser. I remember my grandmother using hers constantly. Grocery bags went straight into it, and she reused the same ones for years. In a way, it was an early version of “reduce, reuse, recycle,” long before that phrase became common.

But the thing is, I didn’t only see her use it for bags. One time I noticed shampoo bottles wedged inside. Another time it held a loofah and other bathroom odds and ends. If it fit, it went in. It seemed like the 1970s bathroom bag holder had more uses than the name suggests.

The Shower Storage You Didn’t Realize Could Be Helpful
The more I think about it, the more it seems these old bag holders were ahead of their time. For one thing, they have openings that allow airflow and ventilation. That makes them surprisingly useful for wet items like sponges, scrubbing brushes, or even a small shampoo bottle if you place it carefully. Water can drain, air can circulate, and items can dry out more easily — which helps reduce lingering dampness and unpleasant smells. In practice, the 1970s bathroom bag holder functioned as more than simple storage.

Honestly, it almost works more like a drying rack than just a bag holder. I even briefly considered installing one in my own bathroom. My wife wasn’t enthusiastic about the idea, but I still think it’s a fun concept.

Form Meets Function… Sort Of
(Truthfully, it’s not exactly an award-winning design.) Let’s be honest — many of them are not particularly attractive. A lot look like leftover pieces from a plastic factory run, but in a quirky, nostalgic way. It’s the kind of item that doesn’t match most modern styles, yet still feels familiar, like wood paneling or popcorn ceilings. Even with its odd appearance, the 1970s bathroom bag holder is remembered for being genuinely useful.

And that might be part of the charm. This bag holder from the 1970s wasn’t only practical — it’s also a little time capsule. For me, it brings back memories of a period when household items often served multiple purposes. People kept things, repaired them, and repurposed them. I can still hear the classic line: “Don’t throw that away — it could hold something.” Turns out, that mindset wasn’t entirely wrong.

A DIY Revival Waiting to Happen?
Here’s a thought: what if we brought them back? Not necessarily as bag holders, but repurposed and updated. They could become wall-mounted organizers for art supplies, kitchen tools, or even toy storage. It wouldn’t be surprising if someone has already turned one into a plant holder, too.

So if you have one sitting unused in a garage — or still mounted in a retro bathroom — it might be worth keeping. Clean it up, give it a new purpose, and let it live a second life. If you’re feeling creative, you could even paint it a bold color to make it look intentional and fun.
