Here’s a closer look at its features, capacity, and weather resistance to help you decide if it’s right for your space.

We’ll answer common questions about this deck box, from how much it holds to how it stands up to sun and rain. We’ll also compare it to similar Keter models so you can see where it fits in the lineup.

What Are the Key Features of the Keter Signature 100 Gallon Deck Box?

The Signature 100 Gallon Deck Box is part of Keter’s Signature Collection, known for its upscale look. It features a DecoCoat texture that mimics natural wood grain, giving it a vibrant finish that stands out on a patio or deck. The resin material is weather-resistant and UV-resistant, meaning it won’t fade, rot, peel, or rust when exposed to the elements.

The box includes a lid that stays open safely and closes gently, thanks to its design. While the exact dimensions aren’t listed here, the 100-gallon capacity gives you a clear sense of its size—enough to hold multiple large cushions or a stack of pool towels. Assembly is straightforward, though you may need basic tools.

  • DecoCoat texture provides a wood-like appearance without the maintenance.
  • Weather-resistant and UV-resistant construction protects against sun and rain.
  • 100-gallon capacity suits bulkier outdoor items.

How Much Can the Keter Signature 100 Gallon Deck Box Hold?

The 100-gallon capacity translates to roughly 13.4 cubic feet of storage space. That’s enough to store a full set of patio furniture cushions, a stack of outdoor blankets, or a collection of gardening tools and supplies. For many households, this size strikes a balance between ample storage and a footprint that fits most decks or patios.

If you’re comparing to other Keter models, the Signature 150 Gallon Deck Box offers even more room for larger families or those with extensive outdoor gear. On the other hand, the Novel 90 Gallon Deck Box is slightly smaller and more budget-friendly, making it a good option if you have modest storage needs.

  • Ideal for patio cushions, pool towels, and gardening tools.
  • Consider the 150-gallon Signature if you need extra space.
  • The Novel 90-gallon is a lighter-duty alternative.

How Weather-Resistant Is the Keter Signature 100 Gallon Deck Box?

Keter designs its resin products to withstand outdoor conditions, and the Signature 100 Gallon Deck Box is no exception. The material is weather-resistant, meaning it can handle rain, snow, and humidity without warping or cracking. The UV-resistant coating prevents color fading, so the walnut brown finish stays vibrant even in strong sunlight.

Unlike wood, which can rot or splinter, or metal, which can rust, the resin construction requires little maintenance. You can simply wipe it down with a damp cloth to keep it clean. This makes it a practical choice for year-round outdoor storage, provided you place it on a level surface and avoid standing water.

  • UV-resistant coating prevents fading in direct sun.
  • Resin material won’t rot, peel, or rust.
  • Minimal maintenance—just wipe clean.
