The Details


The Suncast DB10300 Patio Storage box has a reasonably modern style, with two-tone tan coloring and some slightly awkward curves, which don’t help the look. The main material is plastic, and will withstand the elements, but isn’t really sturdy enough to sit on. The unit has a clean but plain look, however the design is really quite solid, given its price point and size characteristics.

The unit has a flat lid on the top, so it can be used as a table for serving drinks and food when you are entertaining company. Just remember that adults should not sit on the box, as the box is long and doesn’t have an internal load-supporting framework, so the top can break.

The wheels on one side are very low profile, and function well enough to allow the box to be easily moved from time to time, but are otherwise below the radar in terms of aesthetics.


The Suncast Patio Storage box has a clean look, is durable, and has a huge 103 gallon capacity.
There is enough storage space to fit large cushions, lots of firewood, gardening supplies and some sporting equipment. Compared to similarly large competitors like the Lifetime 130 Gallon Deck Box, it hits an aggressive price point.

The Suncast DB10300 is very sturdy and has a flat lid so you can use it as a table but while you can sit on the box, it isn’t recommended as it wasn’t designed for this purpose.

There have been some buyer complaints regarding the load-bearing capacity of the unit. The wheels don’t operate well under heavy load so you might consider that when deciding on what you will be storing in the unit and where it will be placed. The wheels are not designed to allow for frequent movement, but for occasional adjustments, they are helpful.

This storage box will keep your items dry but this also means that there aren’t any drainage holes. This means that you should only store dry items in the storage box if you want to avoid mold growing.

Material and Build Quality

The DB10300 is made from resin plastic and is not designed for sitting, though it could be used as a table and place to put drinks, snacks, games, etc. upon. The construction simply won’t support much weight, so don’t go overboard. The lid will shut properly to prevent animals breaking in. The unit is also resistant against the elements so it will keep your items dry.

The Suncast DB10300 Patio storage box is made from quality plastic so it will last for years without significant fading or discoloration, and is weather resistant.

As long as buyers understand that the deck box should not be used as a bench, and that the wheels are not designed for frequent use, it is an excellent choice in its price point.

When it comes to after-sales support, Suncast customer service are very helpful and respond to queries quickly. The fact that they offer a 5 year warranty on this deck box is a great advantage, and gives confidence in the quality of their products.


The Suncast DB10300 is very simple to assemble and according to most buyers, only takes about 5 minutes to put together. Suncast customer service are also very responsive and helpful so if you have any issues, you can just make an inquiry with them. The pieces essentially snap together, and no generally no tools are required in order to get the deck box assembled.

Cleaning and Maintenance

The box is pretty easy to clean: simply open the lid and clean with a soft brush and a hose. You can leave the open box in the sun to dry out.
Just make sure that the box has dried out completely before you use it after cleaning as there isn’t any drainage within the box itself. This is an advantage and disadvantage: it means no insect infiltration, no water infiltration, and no rodent infiltration. But it also means no way to dry still-damp pool floats, towels, cushions, etc., so mold growth may be a problem. Be sure to place only dry items inside the deck box.


There are no major accessories needed to use the Suncast 103 Gallon Deck Box. If you want additional water protection, you could consider a YardStash deck box cover. These covers will provide extra protection, but they are certainly not necessary, and certainly don’t improve the looks of the deck box!

The Bottom Line

Buy From Amazon

The Suncast DB10300 would be perfect for anyone wanting that extra storage space that would complement their outdoor setting without standing out too much.
The unit has a clean and modern design, is simple and quick to assemble and is also very easy to clean. The box isn’t very stylish but has a simple yet functional design so it won’t stand out. The flat lid offers more utility as it can also be used as a serving table, but sadly there are no metal rods to support sitting.
If you don’t need seating, then the DB10300 is a great large deck box at an agressive price; if seating is needed, you may want to look to spend a bit more and pick up the Lifetime 130 Gallon Deck Box, or the Suncast 134 Gallon Deck Box, which are larger and more multi-function, but also are a higher price.
