Abstract
Provided herein is a molded vanity top with a surface layer and a composite backing. The backing is made from a polyurethane resin and a filler, which may be any material compatible with the polyurethane resin. The filler is preferably sand and makes-up up to about 85% by weight of the backing. The disclosed vanity tops have the substantial weight and solid sound preferred by consumers, yet are often lighter and stronger than cultured marble vanity tops. Also provided herein is a method of manufacturing a molded vanity top. The interior of a mold is coated with a surface layer. The mold is then filled with a composite backing material made from a polyurethane resin and a filler. After curing, the vanity top is demolded and finished.
