There is a graphic scale to the left of the "after" plan drawing that should help you figure out the sizes you are looking for.

Thanks for the quick response! I had referenced that but was uncertain because it seemed the width of the area for the toilet was 6ft by 12ft and the other longest wall dimensions looked to be 30ft (vanity wall) and 20ft (entry door wall) and that seemed very large. I wasn't sure I was reading it correctly.

When using the graphic scale you need to always start from the 0 ft position. The toilet room measures closer to 3 ft x 6 ft using the scale.

Thank you! My mistake - the highlighted bit threw me off! Thank you again for your reply. You work is inspiring.

I tried my best guess with that and came up about 10.5' wide x 15' long. Hoping I'm in the right ballpark. It's tricky with these projects...every inch counts!
