Ordinary glass is prone to damage and aging from hard water, soap, humidity and more. But ShowerGuard glass is extraordinary. It's an entirely different kind of glass that's protected during manufacturing with a patented ion beam process. This technology permanently seals the glass surface, for a shower that stays beautiful forever with just a minimal amount of cleaning.
Available in 3/8" clear or 1/2" clear.
