What are your goals for the addition?

shower in primary bath, laundry on 2nd floor, separated toilet

BATH in primary too

Uninspired bath layout and those closets are useless. How did you get here? Are you building over an existing portion of the home or can the footprint change?

Not a pro but this would feel like such a pinch point - the person who uses this closet is getting dressed in the bath entrance?

are you def bath people? we nixed ours when adding our master and glad we did

Those aren’t walkin closets at 3’11” deep, they are reach in. Make them 2’ deep with bi hinge doors. But really delete the tub and start over with the whole plan

Bigger secondary bathroom. Add a tub/shower there.

Move laundry over.

Do one bigger walk-in closet in master.

Make bathroom smaller, without a tub.

I dont like the closets like this bath in primary is neccesary
