A fire pit is a good beginner’s project for an outdoor building enthusiast. Most firepits are about 12 to 14 inches tall. Building a fire pit shouldn’t take much time or cost for ambitious do-it-yourselfers who can follow instructions. A DIY fire pit usually has a layer of sand or dirt at the bottom of the stone fire pit. Sand is best for its ability to absorb heat. Lava rocks or gravel are an excellent second choice for the next layer; however, be careful since they are porous and absorb water. If it has rained recently, cure your fire or stand back for about 15 minutes before sitting near the pit. Some rocks that have trapped moisture will explode when the high heat of the fire reaches them. Granite, marble, and slate are good stones for building your firepit since they are dense and least likely to absorb water. Consult a professional if you plan to install a fire pit on an existing patio or deck. If you put a fire pit on a wood deck, flammability becomes an issue.
