Shower door with a retic? Can we say broken glass everywhere. Sliders are made to take 100MPH+ wind debris. The 1/4" glass shower door didn't survive my four year old daughter an her shampoo bottle.
Now, I bet some manufacturers make fall resistant shatter proof glass. But as the "fixer" for the families construction an hotel business. I don't want too tell you how many I replaced because people "pushed" up against them. An a Retic will push on it!
A slider will be double paned to add strength an energy value.
I would use an acrylic sheet before a shower door. But a slider would be cheaper an faster.
Cheap ReliaBilt patio doors come with locks installed for under $300 at Lowes. Scratch an dent or returns run $150. If your area has ReStores, you can find deals.
A cheap perhung full view glass doors would work. Put a dead bolt in it an your good till the snake picks your lock
What ever you decide think about using window film of some type. More so the snake doesn't see out an think food. A Retic striking glass at face level is unnerving.
Good luck!
