I'm using a sub provided by my contractor for glass. Like most things, there is no discussion about details. I told him I want frameless showers, so the sub came and measured and that was about it.

After some research I understand there are different definitions of "frameless". Some people use clamps on fixed panels and consider that frameless and some use only silicone to hold the fixed panels which is truly frameless.

A lot of what I read is older. Today, what is the ideal way to do a frameless shower? What should I expect and what should I communicate to the glass installer?

I have one spot where the glass installer complained about imperfect tile. We are talking an extremely small level variance between tiles. Glass guy said that this will result in seeing more silicone where the gap is wider. He made it sound like it will look bad.

I read something here about wet glazing and Dow Corning 999 silicone (note posts #4 and #6). When applied properly this is silicone supposedly dries strong enough and clear enough to be indistinguishable from actual glass. Sounds good to me but this is from 2005. If requested, can I expect that this product be used? Is it as good as those people say it is? Is there a better way these days?

Other than the silicone issue, are there any other elements I need to clearly communicate to the glass guy? I don't know what I don't know so I need help. I've had enough bad outcomes that had to be fixed during this remodel. I need to make sure this is done correctly right from the start. If I don't like the way it turns out I don't want the response to be "You didn't tell me to do..."

TIA
