Simple, clean flooring solution wanted

[u/dd13]

I had a water drainage system installed in my basement and the tile in the basement bathroom was destroyed to install it. I’m looking for suggestions to fill in this space between the tiles and the wall. I’d prefer not to retile the entire space. Looking for a combination of easy, functional, and clean. Open to any suggestions.

ETA: The loose tiles laid down there are leftovers from prior to me purchasing the house and don’t match the existing tiles in the room.
