ABSTRACT:
A device for setting and leveling tile is provided that comprises an elongated straight edge. The straight edge includes a horizontal tile support flange and a vertical flange. A support leg is adjustably attached to the vertical flange adjacent each end of the straight edge and a bubble level is centered on the vertical flange between the support legs. The thickness of the horizontal support flange is sized so that after all the courses of tile are laid and the straight edge is removed, only a layer of grout is required to complete the installation. If the floor is not level, the support legs are adjusted to center the bubble in the level prior to laying the tiles. When leveling tile around a bathtub, an adjustable brace is affixed onto each of the support legs. Each brace includes and adjustment slot therethrough and a rubber boot secured on one end for engaging the bottom of the tub for supporting the straight edge on the edge of the tub.
