I personally love a king size in a master but they can look too big in some rooms. This may be the case here too, especially with your chosen bed. However as long as you have enough room to move around it you will be comfortable in that regard. If you were to go king I would suggest looking at a bed with just a bed head or a separate bed head with ensemble as this will not dominate the room room to much and make it feel smaller. Then find side tables that are floating or light in structure with open legs so you can see through to the wall. Good luck

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!

i too prefer symmetry but with limited space this option has worked well for me to store all the things you mentioned including a vacuum cleaner and carpet shampooer but another option for you could be to have the original arrangement and use the broom space as an alcove without a door or walls keeping in mind that the counter needs to be at least 2150 wide for the laundry basket, washer, dryer and skinny tub and should be at least 650mm deep to allow for the water hoses and cords and power points behind, leaving an alcove about 450mm by 1m with no door and a very narrow side opening to squeeze everything in

something to keep in mind is the thickness of the walls and correct installation of the in wall cisterns and best practice for plumbing and noise control in adjoining rooms so consult your designer and plumber to confirm suitability of any arrangements but for our two in wall cisterns we have a thicker reinforced stud wall in one and the other has the cistern built into an extra cavity in front of the stud wall with a section of counter over the top ....my suggestion would be to have the powder rooms arranged as follows with the option of the extended counter over the extra cavity for the cistern if necessary
