If you’ve ever stood in your kitchen, staring at that soggy, mildew-prone sponge sitting on your sink edge, you’ve probably daydreamed of a better way to store it. A quick scroll through home goods websites will show you hundreds of pre-made sponge holders, ranging from sleek stainless steel countertop models to tiny acrylic suction cups. But as a sponge holder supplier who’s spent the last 7 years testing, designing, and shipping these products, I get a lot of questions: “Can I make my own sponge holder instead of buying one?” The short answer is yes—but before you grab your glue gun or drill, there’s a lot to consider beyond just “will it hold a sponge?” because the right sponge holder isn’t just about shape—it’s about preventing the very thing that makes sponges gross: moisture buildup, bacteria growth, and mold. Sponge Holder
Let’s start with the science, because that’s where most DIY attempts go wrong. A kitchen sponge is home to up to 10 million bacteria per square centimeter when left damp (studies from the University of Arizona found that a single used kitchen sponge can carry more bacteria than a toilet seat). The number one way to slow that growth is to let the sponge dry completely between uses. Pre-made sponge holders are designed for that: most have drainage slots, elevated bases, or open frameworks that let air circulate around the sponge’s whole surface, not just the parts touching a tray. If you build your own, that design has to work with that science—otherwise, you’re just creating a fancy wet spot for bacteria.
I’ve seen DIY attempts that use a small terracotta pot saucer, a mason jar lid, or even a cut-up plastic water bottle. But here’s the catch: terracotta, while porous, traps moisture if you don’t let it fully dry between uses, and the flat saucer often holds pooled water around the sponge’s bottom. Mason jar lids are too shallow, so the sponge will sit directly in water, rotting it faster. A cut-up water bottle might drain, but it’s too rigid and doesn’t have the space to let air flow through the sponge’s side—so the middle of your sponge will stay damp. That’s the part that breeds the most bacteria, right where it’s not getting any air.
If you’re set on DIYing, there are ways to make it work, but they have to align with that science. Let’s break down a simple, science-backed DIY sponge holder you can build with stuff most people have at home. First, you need an elevated base: something that lifts the sponge at least 1 inch off the surface, so water can drip without pooling. I recommend using a couple of small wooden dowels, or even thick popsicle sticks, glued to the bottom of a small square of non-porous material—like a stainless steel scrap, a piece of thick acrylic, or even a clean plastic cutting board scrap. The glue here has to be food-safe, obviously, since it’s going near your sink and food prep area.
Next, the part that holds the sponge: you need space between the sponge and the holder’s walls, so air can circulate. Don’t just create a tight slot for the sponge to slide into—instead, make two small, curved arms that cradle the sponge’s sides, leaving an inch of open space around it. Drill a few drainage holes in the elevated base, too—drill 4-6 small holes, each no bigger than a pencil eraser, so water can drip out instead of sitting. If you don’t have a drill, you can melt small holes in a plastic base with a hot nail (just make sure it’s food-safe plastic) or cut tiny slots with a utility knife.
But even a well-designed DIY sponge holder has downsides. Most DIY projects use materials that aren’t designed for constant kitchen moisture: untreated wood will warp, stain, and harbor bacteria over time, plastic can scratch easily and trap food particles in its surface, and terracotta can crack if it’s exposed to sudden changes in temperature (like if you leave it near a hot sink sprayer). Pre-made sponge holders, by contrast, are made with materials tested for long-term kitchen use: food-grade stainless steel that resists rust and bacteria, BPA-free silicone that’s flexible and easy to clean, or coated metal that doesn’t scratch or stain.
Another thing I see customers miss when they try to DIY: the right size for their sponge. Kitchen sponges come in all shapes and sizes—standard rectangular, square, even round for small sinks. A pre-made sponge holder is designed to fit the most common sponge sizes, with slots or cradles sized to hold either a standard 4×2 inch sponge or the smaller “mini” sponges for dish brushes. If you build your own, you’ll have to measure your sponge perfectly, and if you switch to a new brand or size later, your holder won’t fit. Pre-made holders are adjustable in many cases, so they can work with almost any sponge.
Wait, but what about cost? A lot of people assume DIY is cheaper than buying, but let’s do the math. Let’s say you build one from materials you have at home: if you have dowels, glue, and a plastic scrap, that’s $0. But if you don’t have those, you might spend $5-10 on materials—more than a basic pre-made sponge holder, which usually costs between $3 and $15, depending on the material. And that pre-made one will last 2-3 years with proper cleaning, while a DIY one made from cheap materials might last 6 months before it warps or gets too dirty to sanitize.
I’m not saying DIY is impossible. I’ve seen customers build great holders that work for their specific sink setups—like a custom holder that fits a tiny corner sink, or a holder that doubles as a soap dispenser base. But here’s the thing: as a supplier, I’ve tested hundreds of designs, and the best sponge holders follow three non-negotiable rules that are hard to replicate with DIY: 1) They allow 360-degree air circulation around the sponge to prevent moisture buildup, 2) They have a drainage system that removes all water, not just some, and 3) They are easy to disassemble or clean thoroughly to kill bacteria.
Most DIY holders fail at the third part. If you glue parts together, you can’t take them apart to scrub out food particles or mold that gets stuck in cracks. Pre-made sponge holders are designed to be fully disassembled, or have smooth, seamless surfaces that you can wipe clean in 10 seconds with a sponge and dish soap. Some even have features like a tray that’s dishwasher-safe, so you can sanitize the whole holder every month, which is a key step to keeping your sponge area bacteria-free.
That said, if you’re someone who likes DIY projects, go for it—just follow the science. Avoid tight, enclosed spaces, use non-porous, food-safe materials, and make sure water can drain completely. But if you want a reliable, low-maintenance sponge holder that works as well as it should, without the guesswork of measuring, drilling, and sanitizing a homemade one, a pre-made option is worth it.
Now, for the part I deal with every day: customers who come to me looking to buy sponge holders, but also small businesses that want to add sponge holders to their product lines, or restaurateurs needing bulk orders for commercial kitchens.
