H2OFF Clean Glass Technology – H2OFF is a polymer that bonds to the glass. It is applied to the inside surface of all Marina, Cove and Pier Collection tub and shower doors. There is no additional charge for this feature. It is not available for the Tides Collection. H2OFF makes cleaning the shower glass much easier and protects it from harmful contaminants that can otherwise damage the surface. Consumers should be advised to clean H2OFF protected shower glass with a soft cloth or sponge. For best results, the consumer should squeegee the enclosure dry after each use.
