The floor of the firebox and the protective floor extension.
Two parts: the inner hearth (firebox floor) and the hearth extension (the non-combustible projection in front of the firebox). IRC requires the extension to be at least 16" deep for fireboxes under 6 sq ft, 20" for larger.
Hearth work is part of what we do across Dallas–Fort Worth. CSIA-certified technicians, a photo report of what we actually saw, and a written quote before anything starts.
