Bathtub drain in a new basement bathroom

Hi all, I'm looking for some guidance. I am building a new bathroom in my basement, and the concrete floor was poured with sewer already stubbed in. I am currently at the stage where I have the bathroom framed in, and am trying to figure out how to handle the shower or tub. I have been around and around trying to figure out how best to do this. Currently, the sewer stub is 6 3/4" away from the wall where the shower head would go, and 18 3/4" away from the side wall.

The current drain position is messing me up in all sorts of ways. We thought about installing a standing shower, but most of the drains in those are centered in the shower, which is far greater than the 6 3/4" I currently have. We recently bought a bathtub with a shower wall kit, and the drain is around 8" from the end of the tub.

When I went to buy the bath drain, all of the kits are made for the drain to be directly below the overflow of the tub. Which means, I'd have to move my tub away from the wall 6" and waste that space in my bathroom.

Does anyone have any ideas???

1 : install tub

2 : assemble waste/overflow kit to fit tub

3 : mount waste/overflow

4 : Using a p-trap, determine how best to position the drain below tub

5 : cut drain line accordingly

6 : measure for tailpiece

7 : glue p-trap to drain/tailpiece/waste&overflow

You should have an 8x8 or 12x12 area in the concrete boxed out in order to do the work below. If you think the p-trap won't hook up due to concrete, you may need to chip some out. We do this occasionally.

If your drain is deep enough, you can sometimes use 45 or 22-1/2 offsets on the tailpiece to get it to hook up.

Hope that helps.
