Bathroom / Laudry room piping advice

[John]

Hi guys,

Have a laundry room here being done over...need some advice. The 2nd floor bathroom is located above...so before I close up all walls would like to get rid of the old galvi pipe which the actually goes into 2" cast iron, that has hair line cracks.

The Pics have 2 pipe drains, left one is 1 1/2"drain for tub, right one is 1 1/2"drain for sink. on the right wall 90 degrees to that plan on replacing the washer piping.

How would you pipe up the 2 drains shown in the pic which are the tub & sink? Would like to make it nice an neat. Also I guess final connections for the washer would have to be under the floor since it's 90 degree from the 2 drains in the pic, plus I have a recessed convector in the wall thats in the way anyways.
