Ordinary glass can be prone to aging and damage due to hard water, soap, and humidity.

But ShowerGuard glass is a different kind of glass entirely. It’s protected against corrosion and discoloration with a patented ion beam process, permanently sealing the glass surface.

As a result, with just a minimal amount of cleaning using ordinary household products (see Cleaning Instructions below), ShowerGuard glass will look beautiful for years to come.

Best of all, ShowerGuard even comes with a 10-year Limited Warranty!

Warranty Requirements

  • ShowerGuard glass is warranted to the original consumer purchaser to be free from visible staining, corrosion, or discoloration for 10 years from the date of purchase when regularly maintained according to recommendations by Guardian Industries Corp.
  • This warranty is void if the product is damaged by accident, improper use, or other causes, or if the product is altered in any way.
  • To obtain coverage under this Limited Warranty, original end-user customers must register their purchases online at www.showerguardglass.com within 90 days of the purchase, except where state law prohibits requiring registration.
  • Customers should retain a copy of the online purchase registration page along with their invoice.
