We considered all of your ideas and more, to the point where we had a sure plan, quoted and ready to go - only to be surprised when we actually saw it. That plan was to make the current ensuite the main bathroom and enter off the end of the room, to reconfigure the WIR to a third bedroom and to make Bed 2 the new master with a walk-thru robe to the new ensuite - currently family bathroom. The issue was that despite taking room from the existing wardrobes between the WIR and Bed 2, the area was just too small - so back to the drawing board. What we have decided to do is keep the same floor plan, knowing that if we choose to sell and return the WIR to a third bedroom it will cost approx. $4K - we think this is a great return on investment, but for our needs the WIR is a big benefit. It turns out our draughtsman missed some vital space where our current pantry exists so we have been able to utilise that space and move the pantry. This has allowed us to change the opening to the main bath to be adjacent to the back door/hall area which removes it from the kitchen/dining/lounge. Despite our best efforts we couldn't make room for a separate shower and bath, so we will have a shower over bath (island style) larger vanity (1200mm) and a concealed cistern toilet. Our finishes will do the talking with exposed brodware michaelangelo shower/bath mixers, beautiful marquina carrara and nero mosaic floor tiles and subways together with a statement wallpaper. We will retain the ensuite as is but we will make the shower significantly bigger, add a large vanity and concealed cistern toilet as per main bathroom. Same finishes. The trick in the ensuite is that we will cover the existing windows opposite the existing shower with the vanity and shaving cabinet (they are frosted from the outside) so we can utilise that wall and it makes no difference to the outside of the house - plus they are double glazed and don't open on that wall so it makes no difference to light or function. Here are the floor plans and the before photos , demo has occurred and we'll be framed and lined prior to Christmas, so stay tuned for more updates!

Based on the plans you provided I would go with number 2 (top row - right) with everything on the right hand side, so you walk in the door and the room looks spacious and you are not looking directly at a toilet from your hallway. All the plumbing runs along one wall and that is always the cheapest option and you can have a heated towel rail or similar running along the wall next to the entry. If it is possible I would rehang the door so it opens to the right not the left and then I would swap the toilet and basin so the toilet is tucked behind the door (for a little more privacy) and the vanities will be next to the shower. Good Luck.

my program is a vintage 3D Home Architect version 4 that i've been using for many years and i believe is no longer available but Siriusky has recently acquired a similar program ...i didn't mean "level the house" i meant add a raised timber floor to match the living room floor with the rest of the house...and, when costing your project make sure you do comparisons of all the options to consider best value for money spent...is the property for renovation and immediate resale, for your own use or for immediate rental? each option should have a different plan and a different budget and you need to cost each option to make the best decision and the suggested kitchen is a simple one line DIY flatpac with a simple island table and should be considered against the extra value of the third bedroom

two more ideas for your family bathroom keeping the door the same. 1. has room for a 600 towel and bathroom items cupboard. 2. could have a nib wall across the room behind the bath across to the shower / toilet wall with a sliding door to separate the toilet and still allow the vanity and shower to be used. Or the nib wall between the bath and vanity could be flush with the vanity or just no nib wall between the vanity and the bath, so many choices
