A shower stall threshold structure has two opposed former sections formed of light weight plastic material and adapted to have mortar poured into the space therebetween. The sections are equipped with spacer members and connection bolts to hold the sections in proper spaced relationship until the mortar hardens. Openings through the former sections expose the mortar at the outer faces of the former sections so that tile placed on the sides of the threshold can be adhered to the mortar. One or both former sections may have tile supporting ledges projecting outwardly from their outer faces. A plastic sheet underlying the shower stall may have its edges turned upwardly within the threshold and held in place between the spacer members on the sections. Lines of weakness are provided in the former sections to permit portions of the sections to be broken off to reduce the height of the threshold. Connections at the ends of the former sections permit the sections to be joined with other similar sections to increase the length of the threshold.
