I am adding a toilet, shower and lav to the basement. Concrete is cut out and trenches dug. The bath group will be vented. My question is I am studding out block walls and the shower will be located in the corner.(block wall studed out on left and block wall studded out on back of shower) Right side I will build a partition.
Question 1:When I plumb in the 2" trap for the shower (fiberglass 2 piece. Base/walls) and stub it up I plan on setting the base over the hole to get it as close to perfect as I can for the shower drain.(I won't be able to move to the left or back) Will I have any play with the shower drain? Or does this stub up have to be dead nuts?
Question 2: Which shower drain should I use?
Question 3:I plan on sinking a 6' inch pipe around the 2" shower stub up before I concrete for drain clearance. How far should the 6" pipe go down into the concrete. In other words how deep will the 6" void be around the 2" shower stub up? I know the drain doesn't take up much room but by going deeper will that give me some play in the stub up for drain installation. What is the standard void depth?
Anyone have an answer for me?
