 Shower Drain Rough-In
Author: CTSNicholas (NE)

I purchased a FG shower kit. The base did not come with any drain assembly, just the hole with a sunken bevel so water would always find the drain no matter the thickness - assuming it's within 3/8" probably.

I'm looking online and planning a trip to menards since local shops don't sell the shower drain kits - just the strainer. I'm trying to get ahead of myself and put the drain rough in, so I can get the shower installed and plumb later. I have access above and below the shower base, so would I be safe to rough in the drain, trap and all, then cut a stub pipe and not glue it into the entry point of the trap? Then get the drain, measure the vertical stack, cut to length, and glue the stack into the trap and then the drain piece onto the stack? Or should I just wait until I can make the trip?

Your plan will work as long as you don't run into any problems after getting the drain, but how often does a plumbing project go exactly as planned? What if menards doesn't have exactly what you need? Just me, but I'd wait until I had the drain and made sure about all the aspects so as to avoid a redo afterwards.

The only issue I see is if my trap entry point is too high and that the drain I purchase has a deep nipple that ties onto my vertical pipe, meaning not enough room for the drain to seat properly. I can take a few days off I guess. :P

You may not have any problem, but I know sometimes even with lots of thoughtful planning I run into something that didn't go like I thought it would. The guys with a lot of experience probably don't have that happen much but the rest of us can usually count on it. They say someone never makes only one trip to the plumbing store.

if you are really careful about measuring (plus or minus 1/8 inch) you can glue everything together but leave the riser not glued. get a drain that is called 2 inch compression. they have a rubber gasket that gets compressed around the riser. (self explanatory when you see the drain). attach the drain to the hole in the shower base, set the base over the riser with no rubber in the drain. mark the riser where you want it cut. remove the base, cut and glue the riser, lay down some mortar so the base is rock solid, set the base, slide the rubber over the riser and tighten with the supplied tool.
