All tempered yes. One sheet was rejected when it came back which delayed the build.
So it's 3/4 inch all around and the base is double giving you 1.5" on the bottom.
Are the side pieces of glass sitting on the bottom panel or along side of the bottom panel. I never thought of overlapping the bottom panel like that. Very cool!
Edit: I can see it in the pics, thanks! I can't wait till you fill it
