Depends on your budget.. if you're going to go with a glass door, I would only do frameless and transparent (not obscure, frost, etc). Keep in mind, many of the beautiful photos you may see have an ultra clear color and aren't necessarily indicating a greenish color which is an inherent property of regular glass. A standard glass shower door will always have some green color, which depending on the person, they may or may not like. This green color is only intensified the larger and thicker the panel of glass. The photos you see that look like there is no color is probably because they used a low-iron glass which is generally a lot more expensive. Just remember there is still color, just less...so the same applies to larger and thicker, but generally it's significantly more clear. Another thing to consider with a door is maintenance. If those spots and streaks are going to bother you, see if they can treat the glass with a water repellant so the water beads right off. Otherwise there will be constant up-keep.
