Why ShowerGuard™?  Standard glass corrodes.  ShowerGuard glass is clearly superior.


No matter how hard you try to keep standard shower glass clean, eventually it gets ugly. That's because hard water, soap and even everyday cleaning agents cause a corrosive chemical reaction that roughens the surface of the glass.

This gives spots, residue and scale something to hang on to – making your glass almost impossible to keep clean. Over time, the glass can appear dirty – no matter how often you try to scrub it clean.

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 re-applied.

• With just a minimal amount of cleaning, ShowerGuard glass will stay beautiful for years to come.

• ShowerGuard glass is backed by a 10-year limited warranty. Click here for the complete warranty.

Introducing ShowerGuard Ultrawhite
Glass Care

Standard shower glass can require a lot of effort to keep clean. Staying on top of soap and mineral build-up could be a daily chore.

But ShowerGuard's patented technology helps keep minerals, scale and soap scum from sticking. A soft cloth or wet sponge and most common household cleaners are all you need for periodic maintenance.

According to the U.S. Geological Survey, 85% of American homes are supplied with hard water. Water described as "hard" is high in dissolved minerals, especially calcium and magnesium.

Over time, these minerals can build up on shower glass, making it appear dirty or cloudy.

ShowerGuard's patented technology resists this. So your glass can stay beautifully clear, no matter what type of water you have.
