7 Best Slim Ice Cube Trays For RV Fridge That Maximize Every Inch

You’ve finally organized your tiny RV freezer, fitting everything in like a game of Tetris. Then you remember ice. That bulky, unforgiving tray from your sticks-and-bricks house won’t fit, and if it does, it’s a guaranteed spill the second you pull out of your campsite. This isn’t just about frozen water; it’s about reclaiming precious, limited space.

Why Slim Ice Trays Are an RV Freezer Essential

The freezer in an RV refrigerator is a lesson in compromise. It’s usually a fraction of the size of a residential unit, meaning every single item has to justify its existence. A standard ice cube tray is a space hog, with a clunky design that leaves inches of wasted air above and around it.

These bulky trays rarely stack well. They slide, they teeter, and they prevent you from placing anything on top of them. In a freezer where you might be storing a week’s worth of food, that kind of inefficiency is a deal-breaker. You end up with a half-full tray taking up the space of three other items.

Slim ice cube trays are designed for this exact environment. They are engineered to be narrow, low-profile, and, most importantly, stackable. By minimizing their own footprint, they maximize the freezer’s usable volume, allowing you to make ice without sacrificing space for your frozen vegetables or that emergency pint of ice cream.

OXO Good Grips Tray for Spill-Free Filling

The biggest challenge with ice in a moving vehicle is water’s tendency to go everywhere. OXO’s Good Grips No-Spill Ice Cube Tray directly tackles this problem with its brilliant silicone lid. This isn’t just a flimsy cover; it seals tightly to the tray, allowing you to fill it and carry it to the freezer—even at an angle—without a single drop escaping.

This feature is a game-changer for RV life. You no longer need to perform a delicate balancing act or wait for the RV to be perfectly level to make ice. You can slide it into a packed freezer on top of lumpy bags of frozen fruit without worrying about a sloshing mess that will freeze your drawers shut.

The trade-off is that the lid adds a small amount of height compared to a lidless tray. However, the ability to stack these trays securely and the peace of mind that comes with a spill-proof design is, for most RVers, well worth sacrificing a few millimeters of vertical space. It turns a frustrating chore into a simple, reliable process.

Arrow Home Products: The Ultimate Space-Saver

Sometimes, the simplest solution is the best one. Arrow Home Products makes incredibly basic, no-frills plastic ice cube trays that have one massive advantage: they are exceptionally thin. If your goal is to cram an ice-making tool into the smallest possible crevice, this is your answer.

Think of these as opportunistic space-fillers. They can slide into that half-inch gap between the freezer wall and a box of fish sticks. You can lay one flat on top of a vacuum-sealed steak. Their rigid, narrow design allows them to fit where flexible silicone or bulkier lidded trays simply can’t.

Of course, this minimalist design comes with drawbacks. They don’t have lids, so they’re prone to spills if you’re not careful and can absorb freezer odors. Releasing the cubes often requires the classic twist-and-crack method. But if your top priority is pure space efficiency and you have a steady hand, nothing beats their ability to disappear into the forgotten gaps of your freezer.

Tovolo Perfect Cube Trays for Compact Stacking

Tovolo trays are for the RVer who craves order and stability. Their design brilliantly combines a flexible silicone mold with a rigid frame, solving the biggest problem with all-silicone trays: floppiness. This structure means you can stack multiple trays with confidence, creating a solid, stable block that won’t collapse when you rummage for something underneath.

This stability is critical in a small, often-jostled RV freezer. The trays lock together, so they don’t slide around during travel. The silicone construction also means that even when frozen solid, the cubes pop out easily without a fight. You get the easy release of silicone with the stackability of rigid plastic.

Tovolo is also known for its larger, "perfect" cubes, typically 1.25 inches. These melt slower, which is a fantastic bonus for your evening cocktail or glass of iced tea. While you get fewer cubes per tray, the combination of superior stacking, easy release, and high-quality ice makes them an excellent choice for a well-organized freezer.

Kitch Easy Release Trays for Effortless Cubes

We’ve all been there: wrestling with a rigid plastic tray, twisting it until it cracks, and sending ice flying across the floor. Kitch Easy Release Trays are designed to end that frustration for good. Their signature feature is a hybrid design, with a sturdy plastic frame and individual soft silicone pods on the bottom of each cube compartment.

This simple innovation makes all the difference. To get a cube, you just push on the soft bottom, and one pops out cleanly. There’s no twisting, no banging, and no need to empty the whole tray just to get a few cubes. This is especially useful in an RV where counter space for wrestling with a tray is limited.

Most Kitch trays come in multi-packs with stackable lids, making them a great value. They hit a sweet spot between the absolute slimmest designs and the bulkier systems. For anyone who prioritizes convenience and hates the ice-release struggle, these trays offer a practical and space-conscious solution.

W&P Peak Everyday Tray: Style and Function

For those who believe even utilitarian items should be well-designed, the W&P Peak Everyday Tray is a top contender. It feels less like a cheap piece of plastic and more like a thoughtful piece of kitchen equipment. This tray combines a premium silicone body with an internal steel frame, providing rigidity for filling and stacking without sacrificing flexibility for easy cube removal.

The design details are what set it apart. The included lid does more than just prevent spills; it protects the ice from absorbing freezer odors from nearby foods—a common problem in a small, packed freezer. The thin profile and clean lines also mean it stacks beautifully, creating a neat, organized look.

This is a premium option, and it comes with a higher price tag. But for that investment, you get durability and a superior user experience. If you’re full-timing or simply appreciate tools that work exceptionally well, the W&P tray is a functional upgrade that makes a small daily task a little more pleasant.

Lekue Silicone Tray: Flexible and Spill-Proof

Lekue takes the concept of a spill-proof tray to the next level. Instead of just a lid that sits on top, many of their designs create a completely sealed container. A small, designated fill hole allows you to add water after the lid is already on, virtually eliminating any chance of a spill between the sink and the freezer.

This is an ideal design for life on the road. It doesn’t matter if your RV is parked on a slope or if you hit a bumpy patch of road; the water is securely contained. The all-silicone construction also provides excellent flexibility, allowing you to twist the tray to easily release the cubes.

The main consideration is that the fully flexible body can be a bit wobbly when carrying it, so it’s best to place it on a flat, stable surface in your freezer. The fill-through-the-top design can also be slightly slower than filling an open tray. However, for maximum spill protection and pure, odor-free ice, the sealed Lekue system is hard to beat.

Samuelworld Trays: A Complete Icemaking System

If you use a lot of ice or frequently host fellow travelers, a single tray might not cut it. The Samuelworld system approaches this by packaging multiple slim trays with a dedicated ice bin and a scoop. It’s less of a tray and more of a miniature ice factory for your RV freezer.

The workflow is simple and efficient. You freeze a batch in the trays, then easily dump the cubes into the storage bin. This immediately frees up the trays to make another batch. Instead of having three or four trays taking up horizontal space, you have one compact, vertical bin full of ready-to-use ice.

Yes, the bin itself takes up a chunk of freezer real estate. But it’s a strategic use of space. It consolidates your ice into a single, easily accessible location, preventing you from having to unstack three trays just to get to the frozen corn on the bottom. For high-volume ice users, this trade-off of a dedicated spot for a large supply and constant production is a clear win.

Ultimately, the right ice cube tray is the one that solves your biggest freezer frustration. Whether it’s the spill-proof security of an OXO, the sheer slimness of an Arrow, or the production capacity of a Samuelworld system, being intentional with this small purchase can make a surprisingly big difference in your tiny kitchen on wheels.
