I tried every suggestion in this post and nothing worked for me. I live in New Hampshire and it makes sense stains will be different depending on where you live. Finally, I found the solution ...a pumice stone. There are several brands available online. I found this one in my local grocery and hardware store, and it's pretty inexpensive. Just use with water ..it didn't take a lot of muscle....just a little patience but it worked beautifully. I had gone so far as to get a quote for replacement shower doors and stumbled on this product just before I was ready to place the order. So glad I tried it because new doors were more than $800. Just wanted to share in case it helps someone else!

I have glass tiles but I guess mine are different. But I will say this if you get 10 glass door companies out there you will get 10 opinions on what needs to happen. The people that don't bring levels and such get rid of them first. They wanted to put support rods across the top of mine and drill into my floor. Here is how mine is constructed maybe you can tweak it to fit your needs. I have a 28" wide x 80" tall 3/8" thick door that has 45 deg hinges that swings off of a 1/2" thick piece of glass that goes from floor to ceiling. There are 2 clips on the wall and one at the top where this glass goes to the ceiling. This holds the panel steady. It is just siliconed at the wall and bottom, no drilling into floor. The other fixed panel is 28" wide x 80" tall 3/8" thick and has only one small attachment at the top corner the rest is siliconed in. It works beautifully and you see the true beauty of the glass not a bunch of hardware and head rails. My Glass tiles are bullet proof as it is glass laminated onto porcelain and it is really tough to drill through but I don't think they should have a problem using the correct drill bit and possibly keeping it wet while drilling with acetone or water to keep it cool. This company might have had problems before and they are now nervous with the situation. I suggest that you keep getting quotes. It's a pain and slows the process but in the end positive results.

Thanks for your thoughts, everyone. The reason I am hesitant to go the permanent route was it is so permanent. And if we don't like how it turned out, that's an expensive mistake. The reason I am hesitant on film is because I'm not sure how it holds up from a quality perspective. Oaktown: Wow, that's cool film. I wonder if it works? Very interesting. Virgil: We have tried pinging the architect on it. He hasn't responded to our emails. I wouldn't mind him being more engaged on the issue, but maybe he thinks it is too small an issue to get involved? I imagine if he did weigh in, he would say to just leave it all plain glass (no obscure). I will try to give him a call and ask about it. I get the impression that he thinks we over-think things.

I would do regular clear instead of the low iron glass (less greenish). The price isn't worth it and the only time you can tell the difference is when your looking at the edge of the glass. As far as the coating, it's amazing against hard water. You won't have to squeegee every day. Hope that helps, I work at a glass company.
