I agree with emily. if you want leave connections and/or a little extra room for what you don't want, but feel you may need for resale. I think the tub is a pretty important item. wet room not at all, and shower is give or take. i would prefer a big shower and a tub for soaking in, but I have always had the combo. I remember my mom built during big wet bar craze, she did not care for one. had space built, capped off connections and use as a closet. Now it is 35 years later, everyone wants to buy and tear down. Darned if you do, darned if you don't. i agree, I would also really like the separate toilet, we are not share everything people.

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers

windows in master bedroom need to allow views and privacy and much as i would prefer bed on NE this keeps the bed in view towards and from family room so prefer bed on south wests wall and small sliding doors pushed towards north side of room with tall narrow window beside sliding door and highlight window for light with privacy and wall space for chest of drawers...acknowledging theta the pwdr doesn't have a window but my suggested arrangement uses less total space more efficiently and is better for older kids and long stay visiting parents (more people can use the various options at the same time) and a small ventilating skylight will exhaust and brighten the toilet and vanity area ...the wide door into the lounge can be a stacker or stable door so you need to investigate local options (and everything is expensive unless it does what you want...we always use solid core doors that can be ten times the price of a basic hollow core door but love them so we economise elsewhere) and barn door between entry and family would be OK as long as you like them and it doesn't compromise lounge doors but could look ok if both doors are the same style and different widths...and location of dishwasher is personal and if you have already been unhappy with sink in main kitchen then have it in the scullery...main advantage of my suggested kitchen location is that it's closer to the front and the family area and external doors and the pantry uses the central space that can be much better illuminated with another ventilating skylight instead of a tiny external window and noisy exhaust fan

To a fair degree , its not too bad , coming off the dining , but conversely I understand why its not ideal . As the plan seems to say 'final' , I assume it is locked in and you definitely don't want to move any external walls . The only other option I can see would be to move the door to Bed 2 to the 'right' on your plan ( to the inner end of the Bed 2 WR ) , and have the door to the Master entering from this longer hallway into what is now the WIR . If you went down that route , you could either rearrange the ensuite and WIR and have a hallway , but the other option would be maybe 4 or even 6 doors and a non-walk-in robe along the wall that currently has door . Thinking , you could even walk through the WIR I guess , but that would be at the bottom of my preferences .
