How Hearth Height Impacts Fireplace Doors & Accessories
The position of your hearth directly affects how fireplace doors fit and function. Since the hearth can be flush with the floor, raised above it, or completely absent (as in suspended openings), it’s important to choose the correct door style. The two main types of doors are inside fit and overlap fit, and each has specific compatibility depending on your hearth type.
Inside Fit Fireplace Doors
-
Installed inside the firebox opening for a clean, seamless look.
-
Work best with flush hearths and no hearth/suspended openings, where there’s no obstruction at the base.
-
Provide a sleek, modern finish but require precise measurements.
Overlap Fit Fireplace Doors
-
Installed so the frame overlaps the opening, covering part of the surrounding masonry or prefab face.
-
More versatile since they work with flush hearths, raised hearths, no hearths, and raised fireboxes.
-
Offer greater flexibility for uneven or non-standard openings.
-
Provide a bolder frame and slightly more forgiving installation than inside fit doors.
