Glazing would most likely cover up the pattern.
I like the tile and think you can embrace it.

Add a bath mat.
And show the rest of the space.

If your not happy, I’d say you’ll most likely have to redo it or learn to live with it.

Will show the rest of bathroom next week when vanity is put in (took 6 months to get the vanity-supply chain issues). I really am trying to embrace it as i do like the tile, but it may have been more appropriate in an italian villa and not a suburban house built in 1995! i have a tendancy to rush into decisions and this one was one of those times! I like the pattern, just not the "aged look" surrounding it. Just looks dirty!!!!

And i;m not a neatnick by any stretch of the imagination, so if the dirty look is annoying me, you can bet it looks unclean!

with the proper cleaning, ecoprimer you could have a colored microcement installed

What is microcement? I actually like the current tile design, I just don't like the aged look. It looks dirty. I was thinking a thin slightly transparent white glaze could help brighten it up without obliterating the design. Thoughts?

Here is the bathroom

I have the same tile in both of my bathrooms and love it! I think if you put a different style light you could tie it together better. Here is mine. I also use dark gray bath mats. The half bath has white baseboards like yours and a dark gray rug.

What color grout did you use?

You might be able to solve this by painting the walls more of a creamy white. I would keep your trim a true white but adding a cream tone might help that tile blend in and not seem dirty against your white walls, trim, and counter. Maybe try a big swatch and see if it helps.

I think the grout was a sand color. Sarah, when you clean the tile, how can you see if they are actually clean? The fake aged spots throw me!

Lol well, I guess they do always look a little dirty but I know they're clean. I did use a charcoal grout, which helped define the tiles better, and didn't add to the dirty

It's a great pattern, but -- yeah -- it does kinda have a "before" look.
