To further clarify, I just found a picture of a similar shower to mine. Instead, they inserted a premade plastic shower pan. As you can see in this pic, there drain is exactly center over the standing area. Im thinking I should either reduce the depth of my bench so that it is truly 3x4 shower pan so the drain is center. Or just move the drain forward 1.5 or 2 inches so that is centered.. I plan to install frameless glass very similar to this shower. So i realize that the drain will be visible from outside the shower and thus should probably be exactly center for aesthetic purposes.. To me, though, the bench in this picture (which i believe to be 11 or 12inch depth) is too shallow to sit comfortably.. The bench I made is very comfortable size wise, with room to lean back somewhat.. P.S. I am installing a custom mortar shower pan, and will not be using a premade... Would appreciate any opinions or ideas, as I am trying to put this pan in immediately.. Here is a link that might be useful:

I see, did not notice that. Grade 1: This is the weakest of all standard grade ceramic tiles. It’s really only suitable as a wall tile. Grade 2: This is best for light traffic areas. Again, a great product for wall tiles, but it will also work in residential bathrooms, where foot traffic is minimal. Grade 3: Where ceramic tile ratings are concerned, grade three is most common in residential building, and perfect for light to moderate traffic. This makes it a very sensible choice for residential kitchens, countertops, residential flooring, and all areas that receive lighter wear and tear (i.e., grade 1 and 2 areas). Grade 4: This grade is a step up from grade 3 tile grades. It’s still a good choice for residential uses, such as tile floors and countertops, but it can also take the heavier abuse of light commercial foot traffic, such as you’d find in a doctor’s office. Grade 5: This stuff is as tough as it gets. When it comes to standard grade ceramic tiles, grade 5 is built to take a beating. It’s mostly used in high traffic commercial areas such as shopping malls and airports. http://www.homeadvisor.com/r/ceramic-tile-grades/#.V5PoY_krK1s

Typically we match the bathroom floor to the shower floor. If the bathroom floor tile is too large and slippery, we'd cut it into smaller pieces. Do make sure that your shower floor tile is not slippery when wet. There are products that you can put on the tile afterward to add some grit if needed. Your shower most likely has a threshold and make sure that is well-delineated so you won't stub your toes. Keep in mind that natural stone requires more maintenance and is not as resilient as porcelain tile.

My sister has a small bathroom and put the marble look shiny porcelain on the floor. Big mistake!! Sooo slippery
