Clear shows every water drop, if that will bother you go with some texture. But it's a kid bath....and your "kid" won't be 7 forever...next year he will be 8...and so on.

Clear Glass with Shower Guard if you are determined to use a glass door. Teach him now to squeegee and clean up behind himself.

It's a pain to keep up. Maybe even impossible.

As a mother of boys, it's my opinion that we pick our battles with them, sticking to the important issues only, especially as they move into the adolescent and teen years. He's not going to squeegie the door every time he showers. You don't want this issue.

This. It just never looks pristine shiny clean. I love the look in theory, but in terms of practicality I think shower curtains are better. Better yet, if have to remodel a bathroom go with a doorless design.

You could ask the contractor to make sure that the wall is built correctly to be able to support a future glass door, but use a shower curtain temporarily. We did that in one bathroom, and installed the door later. We also extended the waterproofing out onto the floor for a bit.

What kind of set-up do you have? A tub/shower combo; stand-alone shower? How wide is it? I personally don't like glass if the shower is narrow.
