Patio bars can be used for your own comfort, but are more frequently used for entertainment. They can be a simple serving cart, or they can be equipped with refrigeration or the option to have plumbing attachments or working electrical outlets. Most have a bucket or bin for ice if they do not have a minifridge built-in. They provide a place to store refreshments or to set out servings of a refreshing beverage or snacks. Your patio bar could be a permanent installation, or it could be equipped with wheels so that it can be stored when not in use.
