I am planning to have Showerguard for the glass in my master bathroom.

My designer said the fabricator recommended Enduroshield. It is marginally less expensive but cost is not a factor as I am more interested in the quality of the product than saving a bit of money for an inferior product.

Insofar as I can tell from the information on their websites, Enduroshield is a spray that is applied to the glass and it can even be applied on site - or as a DIY option as they appear to seal the substance. It has a ten year limited warranty.

Showerguard appears to be a substance that is more than a sealer but somehow permeates the structure of the glass - or perhaps I am not understanding their process. It can only be done prior to installation with no after market available. It carries a lifetime warranty.

I am inclined to go with the Showerguard because it seems to be the better process.

Any more educated insight or experience would be welcome.
