 Yep, there are some key differences between indoor and outdoor kitchens. For example, adding power to an outdoor kitchen comes with plenty of special requirements. You need special outlets, for example, to be protected from the elements and prevent shocks. The plumbing, well, that's got to be set up to be easily drained in the off-season and more. And even the appliances you choose, like a refrigerator, for example, they must be rated for outdoor use because the refrigeration system is actually different when it's used outside.
