The two photos in the composite above are not in scale with each other. The busy old tiles are actually much smaller than the plain new tiles. I'm not sure how authentic or accurate the colors are in these photos, really. And after the tile guy applies white grout to the new tiled surfaces, it may look different.
Well, it doesn't look at all green here, but green was the idea we started with. We definitely need to paint the walls a different color, to try to tie it all together. I think the shower itself is going to be nice. Maybe we'll need to change the tile in the rest of the room after all. And give that shower base a good cleaning.
