A stone threshold is set into mortar over a concrete floor slab, with its width matched to the door frame above. The threshold features eased corners and sits between restroom floor tile and the exterior flooring. A TCA F125 crack isolator membrane is installed beneath the mortar bed over the floor slab. Dimensions indicate a 3/8-inch threshold rise and varying widths across the transition.
