Thinking of tiling our shower walls with white beveled subway tile but would like views on whether this would work well aesthetically if we also have a glass shower wall/door. Two walls of the shower (exterior corner walls) would be beveled tile and the tile would extend beyond the walls of the shower. Two walls of the shower (interior corner walls) would be frameless glass and would need to be affixed to the beveled tile walls.

Here's the dilemma: Because the tile is beveled, there is going to be a gap where the glass wall meets the grout line between each tile, and the gaps would need to be filled with something (silcone?) (grout?) so that there is no water seepage. Would the gap filler ruin the aesthetics? All views would be welcome!
