Not one of the great decorating minds, but I'm not a fan of any permanent item like tile that is trendy. The PO of my current house tiled the master bath within that past 5 years and it's already looking dated. I'm sure there are lots of posters who will disagree.

Here the tile relates to the vanity.

I appreciate your help. So this is a picture of my floor tile and a piece of the countertop:

Here's my bathroom with a new combination:

I really like the penny rounds with the shower wall tile. And I like Mayflower's suggestion about adding a row of plain tile before the accent tile. You could make that work with the blue tile, but maybe consider using the penny rounds again.

I think the taupe in the floor tile may dominate the gray as I'm seeing a warm color palette. That's making the gray shower tile the odd man out. I think it also may be too contemporary with either of the shower floor tiles, and your home looks traditional. I could see either of those shower floor tiles with a large format subway tile in white for the shower walls. I also don't like the stripe of the wall tile with the stripe of the accent tile, nor with the splotchy floor tile. So I'd eliminate the gray wall tile.

The first thing is finding a counter that works with the existing floor as there are limited counter choices. The colors are okay but the splotchy pattern is a bit similar. But it may be the best you can do. Or use a solid warm white, which gives you the same counter you have in quartz, and you're probably ready for a change. A white vanity will make that quartz appear a little warmer and that might be a nice way to separate the counter and floor. Are you keeping that vanity and painting it? Or ordering new doors and drawer fronts?

I'm planning to change the vanity and linen closet...probably paint it but will consider refacing as that's what I did in the kitchen and another half bath and have been happy with it. This afternoon I'm going to see if I can find a different wall tile - one with less pattern to it. A "decorator" at Floor and Decor helped me pick these samples and was originally giving me very busy-patterned wall tiles but I thought there was too much competition between them and the floor tile so this tile I brought home was a quieter choice. The larger subway tiles they had were either too stark white or too gray or a little bit darker taupe. I'll look somewhere else this afternoon. I just want something to add a little excitement to an otherwise bland color palette. I like Traci's suggestion of using the penny tiles above the countertop.

I've always loved this Pratt and Larson penny tile as a backsplash. At first I thought the dark spaces between the pennies was grout but when I went to their website, I saw it's a tiny diamond. Of course you don't need $$$ P&L tile and you could grout for a similar effect, but the mix of colors really makes the tile. Those colors would be perfect for your bath. I would avoid white penny tile as an accent as it reads "bathroom floor" to me. I also like the wide band, which could be repeated in the shower. It looks like 8", which is nice with the taller faucets. I have the Delta Cassidy and love it.

Thanks Mayflowers. I really like that look for the backsplash area, especially with the trim over it. I'll see what I can find for that look.

If you could find a penny tile mix with a cream or other warm neutral, that would tie the counter to the backsplash. A blue-green in the mix would provide an accent color. It shouldn't be too hard to find that mix in a penny tile designed for bath use since those are spa colors. Even a solid penny in a softer blue-green might work. Maybe that's what's wrong with the glass tile you selected--the color is too strong with the counter.

I found a couple more options - a little more subtle.
