The range hood is a vital part of your kitchen equation and your kitchen appliances. It is necessary to remove airborne grease, smoke, fumes, odors, heat, as well as steam from the air above your range or cooktop. How you want to disguise this important piece is up to you. You can have a stainless steel range hood to match your other appliances. You might select a pop-up downdraft vent to only come out when you need it. Another option is to incorporate the range hood as part of your cabinetry. Using the same material as your cabinets, down to the moldings, you can create a focal point with a bit of architectural interest.
This is a fun alternative to get a bit creative with moldings and other forms of millwork. Let your designer know this is an option you are interested in and see what they come up with. The possibilities are endless!
