Reconsider not having a bathtub in your large master bath space, which currently has a good bit of wasted space, for your convenience as well as for future buyers. You also don't appear to have any counterspace or storage by the sinks, the shower is big enough that you don't need a door on it, and a small freestanding soaker tub could fit under the window in the wet area of the space if the door to the bathroom was moved a couple of feet up the wall opposite the sinks. You can't put furniture on that wall, anyway, due to the traffic pattern.

Hey! I think it'd be good if you used the 'Find Professionals' tag to find a bathroom renovation specialist who could help you with what you need.

after watching my daughter and her husband agonize over the way their expensive timber floor has not held up well after 3 years, I would recommend tiles/wood look tiles with under heating. Their beautiful warm expensive floor looks like it always needs a clean and polish, not from neglect, they have cared for it well. One of the boards now has a slight and painful moan when it's stepped on :-( I grew up in a completely wood floor home and although it looked wonderful, my Mother hated it. ....and the mats ! Wood is a lot harder to maintain than tiles ,(no matter what the die hards say) the modern wood finishes are much better than they used to be.... But a piece of wood is rather arty no matter what it's used for and it does demand to be loved and cared for.....and if something goes wrong it's a lot more expensive to fix than sand and cement. Ultimately you have to be happy. BTW underheating tiles is warmer than timber :-)

It all depends on what you want to do in your laundry and what in your bathroom I guess. I appreciate the fact that there might not be enough space to do this but I store outdoor shoes in the laundry and the dog's leash and cleaning stuff. I need room to sort the dirty laundry into piles before washing it. I keep the ironing board in there and I need a tub to wash things in and to do flowers in and to put the odd cloth that wiped up the cat sick before it gets rinsed and washed.. heaps of things other than just washing. Couldn't manage with a cupboard laundry ( piles of washing on the hall floor when using it) and think these kinds of laundry functions might not make a gorgeous lavendery bath or shower feel that luxurious. So I am for as big a laundry with tubs, cupboard and bench nearest the outside back entrance and yes washing line as poss. And a lovely fresh warm bathroom near the bedroom separate from the dirty clothes and boots and all that other stuff.
