Absolutely you can! Our advice is to always install heating under your furniture, unless you are absolutely sure you will never rearrange your floor space. You don’t want to end up with cold floors after moving around your furniture just because you didn’t fully extend your installation. Vanities and cabinets, too, are completely safe to have a heating system installed underneath provided they are floating, standing, or on legs. The cost of increasing the size of your heating installation is quite affordable, often only running in the tens of dollars, but if you have any questions about pricing or specific kinds of furniture, give Coldbuster a call!
