Not only are floating shelves aesthetically pleasing but they are a great space saver. We custom make the shelves to your desired length. At On A Hill And Co. we offer a non sealed option which gives the shelves a more natural feel. The thickness is about two inches to ensure a quality shelf that won’t bow over time. Every shelve that is sealed will be coated with 2-3 coats of a water based sealant which will significantly prolong the shelf life and beautiful grain quality.
