How High Should a Fireplace Be Off the Floor?

It’s not uncommon for a homeowner to decide they’d like to install a fireplace and find that the existing floor structure isn’t tall enough. For example, maybe you’ve got an open-plan split-level ranch house with only 9″ of concrete basement slab between the first and second floors.

In some cases, it might be possible to add a concrete or stone apron in front of the fireplace opening. In other cases, though, you’re going to need to build up the floor around the existing fireplace structure in order for your replacement fireplace to sit off the floor.

Before we get into how high your new fireplace should be off the floor, let’s discuss how you can determine the height of your existing fireplace. Use a tape measure or yardstick to measure from the floor up to the top of the fireplace structure. Write that number down, then pick up your fireplace and carry it outside.
