ABSTRACT:
Apparatuses and methods for shaping a graded surface of a fill material around a drain are disclosed. The apparatus provides an outer ring for positioning within a shower enclosure, an inner ring for positioning within the outer ring and around the drain, a rail assembly connected at each of two ends to the outer ring, and a carriage connected to the rail assembly and the inner ring. Each of the inner ring and outer ring provides a top edge to which the surface of the fill material can be brought flush.
