Even though it can be warm in Arizona, fire pits are a feature that many homeowners are very interested in. The size and shape of a fire pit can vary greatly. A 3-foot round fire pit is easy to fit in even a tiny yard while larger spaces might be able to accommodate a 6-foot or even larger round fire pit. More traditional or architectural style pools and landscapes might also include a square or rectangular fire pit. In addition to the different shapes, a fire pit can be built to burn wood or use propane or natural gas. The biggest benefit to propane or natural gas is that there is never the long clean-up process that is associated with a wood burning fire pit. With gas, you simply turn the key or push a button and the fire is burning and ready to enjoy.
