Hi, Good question. Of course it depends on the size of the shower, the amount of splashing, and your tolerance for some water on the rest of the floor. One detail we sometimes employ is having a very slight lip (say 1/2" or less) at the door. This helps keep surface water from sloshing out of the shower. Your linear drain is a good idea too. DA

water will always splash out, but many factors on the shower will change how much water splashes how far. IF the idea is troublesome, stay away and install that curb.

I love the frosted green tint glass. Can you tell me the type of coating on the glass? What should I ask for to have this look?

That is just normal tempered shower glass. It actually costs more to order glass with a lower iron content that doesn't have the green tint.

size of the shower and direction of the shower head are two primary factors in splashing. Linear drains will keep water from running out, but then a good, single, circular drain is also just fine. Just point the shower head away from the opening and don't try a shower that is less than 36" deep.
