How tall? What type of glass?

Clear glass, frameless,
probably 74 inches high

I did not have any experience with glass door installation yet, but I am in the same area and in the same situation - planning a master bath reno.
I made some research and read lots of online reviews on the local glass companies. Narrowed it down to two companies:
River Glass Designs
riverglassdesigns.com

and

Dulles Glass and Mirrors
http://www.dullesglassandmirror.com/

I will shop around more when we will be ready to install, but these two companies sound very reliable.

As for the prices, Dulles Glass and Mirrors has an online tool to submit a request for a quote. You can choose the configuration, enter your dimensions, choose glass type and hardware type.

I'd use 1/2" thick on the panels and 3/8" thick on the door. The door will be easier to move, and you won't notice the difference in thickness.

What you use for handles will affect the price. If you use Starphire glass, your cost will be $400-$500 more than for plain glass for your size shower. Figure around $2700 for the plain glass from Reston Glass. They do have a 10% off coupon, which will lower the price.

I've used them for a shower door and for replacing a very large multi-panel mirror.

four years ago I purchased from Bel Pre Glassworks and was very happy with their service.
Frameless, Starfire glass, 3/8" door 27x72 and 1/2" panel 12x72 was $1,555

Thank you for the recommendations. Just got a quote from a top rated Angie's list glass
place for about $2300 for all 1/2 inch. I am also calling 2 other places on Angie's and will see what quotes they come up with.

Reston Glass was well priced and easy to work with.
