Got my WEDI Fundo Lingo shower pan last Monday. After finishing the closet wall I wanted to get the pan trimmed before framing the shower because I knew it would be easier. Just in case this might help some one else the way I went about it. I rechalked the edges of the original subfloor. I laid the pan down and pushed it into the corner. Then I stepped on it along the edge of the recessed sub floor. When I pulled it up it had a perfect line to trim. I cut it there and laid it back down, perfect. I still need to make my 1/2″ dado cut. But before I do that I’m going to make the cut around the spacer. Now to plan my next move, any suggestions?
