My first rule for bathrooms is to make sure the toilet is not the first thing you see when you open the door. Move the toilet to where you currently have the shower, backing up against the wall with the door. It's also nice to have the toilet near a window! If you can, convert that door to a cavity sliding door to increase available room in the bathroom itself. A shower along the wall where you currently have the bath would have a number of benefits - it has a window, which is great for drying it out and preventing mould, it is long enough to have a towel rail at the end of it without towels getting wet and you wouldn't need to have a door on the shower (saving space again). I would suggest the shower rose go on the left end of the shower and the opening (in lieu of door) and towel rail at the right end. I would position a wall hung vanity unit on the left wall where you currently have the toilet. 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 think it should fit, width of bath 800 plus 900 for shower approx, you would most likely end up with shorter vanity, I will draw it for you after I post my updated plan. I have run the island to the wall to give you a better length island, the door could be louvered windows as well, full height like others 2400 and glass. No corner cupboards in thei kitchen!!

Again, without dimensions, land size, location and construction data, it's hard to make helpful comments, Harman, but do you really need a dining room and family room as well as living room and rumpus? I think it might be worth considering oklouise's suggestion to convert the dining room to a laundry and pantry. Perhaps in doing so, you could rearrange the kitchen so that it has direct access to the patio (I think U-shape kitchens are somewhat dated and out of favour. I demolished mine despite it being quite new and in perfect condition, because I wanted free traffic flow from the kitchen to the outdoor living area. I hated being trapped behind the bar of the U while others were partying outside, and having to walk in circles to get from the sink or cooker to the party area.) The U shape, in your case, also means you walk in circles from the kitchen to dining room or family room. I'm not the design expert here. Oklouise, Kate and Siriuskey are among those holding that title! They made brilliant suggestions for rearranging my kitchen and I have ended up with a fabulous open-plan kitchen with servery to BBQ area on one side and direct access to the veranda on the other, plus a fantastic scullery and pantry (what used to be wasted space in a store room and hall) and a much larger and more workable laundry that is no longer a traffic thoroughfare. I really think you'd find it worthwhile to post a floor plan with dimensions; location, block size and orientation information, and some data about the construction (especially whether slab floor or timber with access under). You might be pleasantly surprised at the alternate layout suggestions some here would be able to offer. I'm sure you are aware that the kitchen is the focal point for home buyers. Nothing boosts a home's resale value more than a great kitchen - and these days most families seem to want a walk-in pantry, or at least a large dedicated pantry cupboard. So while converting the bathroom and laundry will boost value substantially, I would definitely consider what you might be able to do with the kitchen (subject to budget constraints of course) and think carefully about ensuring there is a functional laundry, conveniently located. Postscript: Check with council about development requirements. We discovered that a roof extension of less than 10 sq m is allowed in our area without approval - just signed off by a certifier. A laundry extension on the left side of the rumpus room might be easier than you think.
