Hi,
Could someone please advise how to close this gap without making it look messy ? We just installed this frame and husband wants to remove all of it and redo it properly so that it doesn’t leave the gap. But I’m thinking it’s not worth the effort since the adjacent wall tile hits the frame (the tile wasn’t cut properly to align with the window base) and it doesn’t come any lower to touch the base of the window. I feel there should be an easy fix to make it look clean. We are talking about less the 2 cm gap.

Appreciate all your ideas.
