Shower Door Latch

I'm looking to replace the latch on the door of my glass shower door. I have not been able to find all the locks at Home Depot, etc. The magnetic door closures I found online that require screws.
Thank you!

At a hardware store. Just because you watched does not mean that it is not there! Go ahead and ask someone who works there!

You can look in the section of Home Depot where they deal with locks and accessories for aluminum storm and sliding doors. They have a lot of things you might be able to adapt to your situation. Usually find an exact replacement for something like a shower door is almost impossible and you have to improvise a bit.
