Recreating this effect?

[Kindnesskindnesskindness]

We are decorating a new bathroom and love this effect. However, I'm aware grout can be a tricky thing to keep clean and bright in a bathroom so I'm loathe to have as much grout as would be necessary with the tiny tiles. Could we get a larger tile that would give a similar effect?

They’re generally tiny tiles on a mesh backing and you grout over them. So unless you can find a tile that fakes the penny tile look then you will have a lot of grout.

I think I'd rather have a slightly different effect. I'll keep searching for similar

You could get a somewhat larger tile which would still be attractive. And there are specialised grouts for bathroom use.
