Toz Odası & Main Banyo

We are reallocating space in our existing two bathrooms to create a full bath or main bath and a half bath. The floor plan for these two rooms is set, but the specific design of the room is where I am looking for help. The full bath will function as the kids and over night guest bathroom. It needs a shallower tub with a couple grab bars (accessible to aging relatives from out of town) and vanity with plenty of storage (kids coming of age). The powder room just needs a little space for storage and a little elegance. This is all part of a larger home renovation making our home more functional for our whole family!
