Fridges are an essential part of any outdoor bar. In most cases they can even act as an additional piece of furniture in the form of table or accent. You have to be very careful in order to make sure that it does not stand out or look tacky but it can actually be a really impressive and useful item for any setting depending on how you have set everything up. It works especially well if you are going for a modern theme and want lots of hi-tech gadgets to complete the look all around.
For many people fridges have become so common that we do not even bat an eye around them. However they would have been amazing for our ancestors and are still extremely useful for us today so we should take the time to appreciate them. Usually they have a strong and sturdy construction which even allows them to support serving dishes or even other furniture. This is one reason that so many of them are built into outdoor bars as well since they work perfectly with everything else.
With Patio Furniture most people just try to hide the fridge away. It goes in a nook or cranny where no one can see it. This is fine if you do not have a nice one or are not planning to make it a part of the design. You should not ignore the possibilities with it if you run a business though. Having a small bar where people can grab their own beers can be quite fun. You could even have it locked normally with a manual release for when you can trust the customers there. Remote locks complete the style.
Vending machines can also serve this same purpose if they are properly chilled. While not something everyone can afford these are made in many parts of the world and can be a useful revenue source for you as well. There are even designer forms of these that you can use to create a different look than the normal mall-style they have grown to expect. That style can actually cause problems with your overall setting and you want to avoid that whenever possible.
As far as outdoor furniture this can take even more maintenance than many of your other vulnerable pieces. You will need electricity and some chemicals, depending on the design, in order to keep everything running well. You may even need a technician to come out at some point in order to make sure that everything is in good shape so keep that in mind as well. Every dollar you spend on it is one that goes towards maintaining an incredible setting outdoors.
Fitting this into a modern, technological setting is find but it can be harder to set this up in an organic, rustic one. You may need to disguise it with a texture that looks like it could fit in with nature and also make sure that your guests understand it is worth it for the convenience.
