A hearth form is utilized for pour-forming a fireplace hearth in the absence of eventual removal thereof from an opening established by floor joists and a conventional concrete masonry unit. The hearth form is preferably constructed from two relatively slidable body portions which may be reinforced by inter- engaged parallel channels or grooves. The body portions collectively define a chamber or cavity into which concrete can be poured. A peripheral wall defined in part by side walls and front walls carry brackets for establishing a predetermined space between the hearth form and floor joists, not just for supporting the hearth form upon nails or fasteners and nail centering marks for establishing the location of fasteners to assemble the hearth form in an associated floor opening.
