Keter Westwood 150 Gallon Resin Large Outdoor Storage Box – Complete Review 2026
The Keter Westwood 150 Gallon Resin Large Outdoor Storage Box for Patio Furniture, Outdoor Cushions, Garden Tools and Pool Gear, Brown immediately stands out because of its dual-purpose design. Unlike rigid plastic bins or wooden chests that warp, this resin deck box offers a seamless blend of utility and style. My testing focused on its ability to protect items from the elements, its ease of use, and whether it truly seats two adults comfortably as advertised.
During the first week, I loaded it with heavy patio cushions that had absorbed moisture from a recent storm. I wanted to see if the interior would stay dry. I also tossed in a few garden tools and pool noodles to test the 150-gallon capacity. The first thing I noticed was the weight—while empty, it’s manageable, but once filled, it’s solid. The resin construction feels substantial, not flimsy like cheaper alternatives found at big-box stores.

What Makes Keter Westwood 150 Gallon Resin Large Outdoor Storage Box Stand Out?
The Keter Westwood offers specific features that make it a top contender in the patio furniture storage category. Here are the standout elements I identified during testing:
* Generous Capacity and Seating: The 150-gallon interior is spacious. I easily stored six large seat cushions, two back cushions, and a stack of pool towels without forcing the lid. Crucially, the top is sturdy enough to serve as a bench. Keter states it seats two adults, and during a small gathering, two guests sat on it comfortably without any creaking or shifting.
* Wood-Plank Resin Design: Many plastic deck boxes look like exactly that—plastic. This unit mimics the look of real wood with a textured brown finish. Unlike real wood, however, this thick exterior resin prevents rusting, peeling, and denting. It requires zero staining or sealing, which is a massive win for maintenance.
* Easy-Lift Mechanism: One of the biggest pain points with storage boxes is a heavy, slamming lid. The Westwood features a hydraulic piston system that allows for a slow, controlled open and close. This is a safety feature for fingers and prevents the loud bang that happens with other boxes during windy days.
* Lockable Design: The box includes molded spots for a padlock (though a lock isn’t included). This makes it an effective lockable garden storage option for tools or pool chemicals you want to keep secure from kids or theft. The lid fits snugly, keeping out dust and light rain.
For those interested in the science behind rotomolded resin durability, industry experts often cite its impact resistance and UV stability. You can read more about material choices for outdoor products on Consumer Reports’ patio furniture guide.
Real-World Performance Testing
I subjected the Keter Westwood to a month of real-world abuse. It sat on a concrete patio exposed to direct sun, sudden rain showers, and nightly temperature drops.
Weather Resistance: As an weather resistant outdoor box, it performed flawlessly. After a torrential downpour, I opened the lid expecting dampness. The contents were completely dry. The all-weather resin and tight seal do their job. Unlike my neighbor’s wooden chest, which is already showing signs of mildew, this box remains clean inside.
Durability: I dragged the empty box across the patio to reposition it (not recommended, but necessary for the test). There were no scratches on the resin surface. I also dropped a heavy wrench from waist height onto the lid—no cracks or dents. The “rusting, peeling, and denting” claims hold up.
Limitations: There are a few downsides. While the resin is strong, it is plastic. In freezing temperatures, the lid mechanism can become slightly stiffer, though it still functions. Also, while the wood-grain look is attractive, it’s not an exact match for real teak furniture if you are a purist. However, for the price point and durability, these are minor trade-offs. Users on forums often mention that ventilation is a concern for moisture, so I recommend tossing a silica gel pack inside if you are storing truly soaking wet items long-term.
Keter Westwood 150 Gallon Resin Large Outdoor Storage Box vs Competitors
When comparing the Keter Westwood to the Outdoor Storage Box landscape, it sits firmly in the mid-to-high tier. Traditional wooden cedar chests are aesthetically pleasing but require yearly sealing and are susceptible to rot. Cheaper, hollow plastic boxes are lighter but often buckle under weight and lack the seating functionality.
Compared to similar resin boxes from brands like Suncast or Rubbermaid, the Keter Westwood often wins on aesthetics. Suncast models tend to look more utilitarian, whereas the Keter offers a more upscale vibe. However, some competitors offer modular stacking systems, which Keter does not. If you are looking for a standalone, heavy-duty unit that doubles as seating, the Keter offers better value than most wooden alternatives, especially when factoring in the zero maintenance required.
Who Should Buy Keter Westwood 150 Gallon Resin Large Outdoor Storage Box?
This outdoor storage box is ideal for:
1. The Entertainer: If you host backyard parties, you need seating and a place to hide clutter quickly. The 150-gallon capacity swallows pillows and games, and the 2-person bench seating is a lifesaver when guests overflow.
2. The Pool Owner: Storing wet floats and towels is a nightmare. This box handles the moisture without rotting. The lockable feature is great for keeping pool chemicals secure.
3. The Low-Maintenance Homeowner: If you hate painting or sealing wood, this is your solution. It looks good year-round with just an occasional wipe-down.
Who should skip this?
If you live in a high-wind area (hurricanes), the box is light enough to be blown over when empty. You will need to anchor it. Also, if you need to store very long items like shovels or rakes standing upright, the 150-gallon dimensions (approx. 23″ H x 45″ W x 17″ D) might be too short.

Frequently Asked Questions
Q: Is this outdoor storage box truly waterproof?
A: While no outdoor furniture is 100% waterproof in a submerged sense, the Keter Westwood is highly water-resistant. The tight seal and thick resin construction prevent rain from entering, keeping your cushions and tools dry during storms. For heavy humidity, adding ventilation or moisture absorbers is recommended.
Q: How durable is the resin compared to real wood?
A: The resin is significantly more durable for outdoor use. It will not rot, rust, or peel like cedar or teak. According to the manufacturer, the material is designed to withstand sun exposure and temperature fluctuations without denting or fading, making it a superior choice for all-weather-resistance.
Q: Can I leave this outside in the winter?
A: Yes, the Keter Westwood is designed for year-round outdoor use. The all-weather resistant materials hold up in snow and ice. However, it is light enough that you may want to secure it or empty it if you expect extreme wind events.
Q: Does the storage box require assembly?
A: Minimal assembly is required. The box comes in pieces that snap or screw together relatively easily. Most users report being able to assemble it alone in under 30 minutes using basic tools.
Q: What is the weight capacity of the lid when used as a bench?
A: The lid is sturdy enough to seat two average-sized adults. Keter designs these resin boxes to withstand significant weight on the top surface, but it is not designed to be used as a step ladder or for standing on.
