Keter 150 Gallon Deck Box Review (Westwood / Premier / Rockwood)

Keter makes arguably best outdoor storage deck boxes – they are affordable yet reasonably well made. Out of their product lineup the ones with 150 gallons of storage capacity seem to make most sense – they are very roomy yet aren’t too expensive. However Keter offers multiple of such storage boxes so which one should you choose?

#1 Keter Westwood 150 Gallon Outdoor Deck Storage Box

Keter Westwood 150 gallon storage capacity is truly impressive – it’s very roomy and you can fit loads of stuff inside. It has brown natural wood slat finish – you won’t mistake it for real wood but it does look nice. Keter Westwood 150 gallon deck box is 61 inches wide, 28.5 inches deep and 25.4 inches high. Inside dimensions are: 56 inches of width, 24.6 inches of depth and 22.8 inches of height.


Body panels are made of weather resistant plastic (Polypropylene resin) and when you first grab them they don’t feel particularly robust however once you assemble the deck box it’s surprisingly sturdy.

Body panels are sturdier than they feel and metal ridges provides support at the right places. Keter Westwood deck box isn’t super heavy duty, but it’s more than sturdy enough for normal use and is strong enough to be sat on (according to manufacturer lid can safely support up to 660 lbs). It’s reasonably comfortable for two adults to sit on it unless you are of short height.


Keter Westwood outdoor deck storage box has hydraulic hinges that keeps the lid open and makes it easy to open and close.

Lid is lockable – there is a place for padlock but it’s not included (you have to buy it separately). However it won’t make it super safe as someone who really wants to get inside the deck box will probably be able to break it (however doing so will be very loud and conspicuous which might prevent thieves).


Keter Westwood deck box is weather resistant and deals well with sun exposure, rain and snow. In most cases it should easily last for years sitting outside. It’s not completely waterproof but it does a good job of staying dry.


Body panels are labeled and most of the assembly process consists of snapping pieces together other than inserting some screws too. It’s easy to put together and doesn’t take much time even if you aren’t handy.


When it comes to value for money Keter Westwood is probably the best outdoor deck storage box you can buy – it’s not too expensive, a lot sturdier than you might expect for something that’s made of plastic, offers lots of storage capacity and will likely last for many years to come!

#2 Keter 240303 Premier 150 Gallon Deck Box

Keter Premier 150 gallon deck box is made of double walled resin plastic. It’s 59.7 inches wide, 28.5 inches deep and 27.5 inches high. Inside dimensions are: 56.22 inches wide, 24.9 inches deep and 25.16 inches high.


Durability wise it feels similar to Westwood deck box but due to double wall design might be a bit more sturdy. It’s not super heavy duty where you would want to abuse the deck box or jump on it, but you can sit on it and expect it to last for years in normal use. The lid of Keter Premier deck box can support up to 660 lbs of weight.


Keter Premier 150 gallon deck box has hydraulic pistons for easy opening and soft closing, they will keep the lid open when you need to put in/take out things inside deck box. Built-in handles which makes opening easier. Lid is lockable but lock is not included.


Keter Premier deck box is weather resistant. Inside manages to stay dry during regular rain but might not during heavy rain or when bottom of deck box is submerged in water.


Assembly isn’t difficult but expect it to take 30-45 minutes to complete. (You can also complete it a lot faster if you are handy and/or try to do it quick).


Quality wise Keter Premier 150 gallon outdoor deck storage box is very similar to Keter Westwood. It might be a bit sturdier due to double wall design but difference doesn’t seem to be significant, on top of that it’s a bit more expensive and less elegant (however that might be totally subjective).

Keter Premier Outdoor Deck Storage Box Details/Specs:

  • Material: Double-walled resin plastic
  • Storage capacity: 150 Gallons
  • Inside dimensions: 56.22″ x 24.96″ x 25.16″

#3 Keter Rockwood Jumbo 150 gallon Outdoor Deck Storage Box

Keter Rockwood Jumbo 150 gallon deck box is made of polypropylene resin plastic. It’s 61 inches wide, 28.5 inches deep and 25.25 inches high. Inside dimensions are: 56 inched wide, 24.75 inches deep and 22.75 inches high.

Just like other Keter products this one feels reasonably sturdy once assembled but a little less than the other two. Since it’s made of plastic it’s not really meant to be abused.

In other aspects it’s very similar to Westwood and Premier deck storage boxes too. Inside contents seem to remain dry even during rain as long as the bottom of deck box isn’t submerged in water. It’s not waterproof but is pretty water resistant. Assembly is pretty straightforward but might take a while to complete (around 30 minutes give or take 15 minutes).

Keter Rockwood Jumbo Details/Specs:

  • Material: Polypropylene resin plastic
  • Storage capacity: 150 Gallons
  • Inside Dimensions: 56″ x 24.75″ x 22.75″
