Maybe if you live in the foothills of Los Angeles, place them under a porch roof and they won't get rained on, then they might last a couple of years. Any other climate/location and it will be a really bad idea. Can you use them in a basement or garage for extra storage?

Waht does the rest of your outdoor area look like this is like deciding cabinet color in your home . I assume you mean the tile on the cabinets ? Wahtever you choose needs to stand up to your climate it does not matter that is is under a gazebo it only matters it stands up to your climate. I prefer outdoor stainless for outdoor kitchens .

Yes, a much wider view of your outdoor space would be great! Even a sketch on graph paper. We don’t know what else you already have available (for example, table and chairs for eating? chairs for lounging or sunbathing? room for either of these things?). What’s your vision for using the small area you pictured? Obviously it’s near a traffic pattern as you say the step on the left leads to a pool …… Is that a door between the two black-draped items, so you need to retain walking space right there?

Perhaps it's best to consider a new location as you say but I wondered if your original corner would work if you turned your layout 180 degrees so it kind of completes the corner of your house. Your walking space would be near the house and your "L" would face out toward the yard. You have some other picturesque areas though and your kitchen should "find" a nice new location somewhere in there!
