Almost there... Just got to cut the top section around the extractor fan. Wanted to leave a 4mm ish gap around it to caulk so that it can be easily removed if necessary. Not quite sure how I'm going to do that cut though. I've been using an electric cutter but do have a manual one. Do you think I should cut in on the electric and score with the manual along the edge of the fan hoping it will snap OK?
