This is a new hardwood floor that is next to my slate stone flooring:
The cut was nice and there is about an inch gap in between:
My hardwood floor guy recommended to just leave it like that and not fill with grout.
Is it a good idea to leave it alone like that? And if so, would it get dusty and even broken at the edge over time?
If I fill with grout, would it look ugly? Maybe due to color mismatch with the old grout?
Any other idea or suggestion?
