I did say I will use it for the sink but I changed my mind as the sink stubouts will be behind a floating cabinet and it would be a waste of money. I will still use the sharkbite valve but I will use the copper stub outs
The toilet is a special case ...when the basement was finished and this bathroom was created there was no room for framing behind the toilet (don't know why) so just behind the toilet there is above the grade windows in a sort of niche since the wall has proper insulation and framing for the rest of it
For that reason I do not have too much space to play with for my piping. There is the black tar paper and then like 1" of blue polystyrene insulation board and then drywall.
So I will have to run my 1/2" PEX in that space and then use a elbow to come out of the wall so the above will somehow protect and rigidize the PEX and still look nice behind the toilet sit.
It is the best I can do. The copper stub outs with a flange seem to need more that 2" behind
