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.

ShowerGuard glass stops corrosion before it starts

  • Its surface is permanently sealed during manufacturing with a patented ion beam process.
  • Unlike spray-on or wipe-on treatments that eventually wear off, the protection provided by ShowerGuard glass is part of the glass itself, so it never needs to be reapplied.
  • With just a minimal amount of cleaning, ShowerGuard glass will stay beautiful for years to come.
  • ShowerGuard glass is backed by a limited lifetime warranty.

Available in 3/8" clear or 1/2" clear.
