Yes, measurements would help. Thank you aldrea1 for other explanation, though. That helps too. It sounds like you are going into a total gut-job! I love this! Great opportunity for your creativity. Also, it looks like you have a petite sized stove. With total remodel you can upgrade to a standard size range. Is this part of your plan? Are you going to replace any appliances? It would be good for you to keep sink and stove in original locations. It is complicated to move the stove's exhaust fan and the sink's plumbing. Not impossible, but probably $$$$$$$ and a lot of hassle…. So, I would start planning with those items--stove and sink on current walls. Wherever you put your refrigerator, it would be best to be sure side view is hidden. If refrigerator stays in current position, you could make peninsula a little smaller, so wall on the right of kitchen entrance could extend further and hide refrigerator edge----Or, move refrigerator to another location… Not too far from sink and counters, though. That would cause you inconvenience. You want a work triangle with not that many steps in-between. Do you currently have a dishwasher? Or are you planning to add one? Not much creativity in placement of a dishwasher---needs to be near water source and drain.. Are you doing the work yourselves or hiring a contractor?

Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)

We have a 900x900 shower and it's plenty big enough. Neither of your proposed layouts looks that great, to be perfectly honest, sorry! In the first layout, you could improve it quite a lot by swapping the toilet and vanity (centre the toilet under the window on the bottom right of the picture if possible), and having the shower door on the other wall (beside the door). Then, you could have a towel rail on the wall beside the door (i.e. behind the door when it's open), which would be accessible from the shower but hidden when the door was open. An 800x1200 shower might be a good size for your space. You'd have to choose a toilet that doesn't protrude too far, plus a narrow vanity. With that layout, you could have a long but narrow wall-hung vanity, with a big mirror covering the wall between the windows, which would make the room feel bigger and would give a good amount of storage.

Like everything , it comes down to budget and 'value for money' -- generally both the cheapest but also the most expensive aren't the best options -- its doing things 'cleverly' . The entrance foyer looks like it may be a bit dark and closed in , but you don't really want to open the wall between it and the kitchen either . Not really in the 'brief' , but I'd look at opening up the doorway into the lounge -- I guess it depends whether you close that door often ? To me , the only way/place to get more room would be 'open' the double doors and however much more you can between the lounge and family room ( before you strike load bearing walls near the wood burner ) , move the dining room to the family room , and then basically do whatever you like with the kitchen , utilising the existing space and the existing dining space . That may work , or maybe you don't want to combine the lounge and family room , in the latter case maybe move the lounge to the existing family room , utilising the window seats and maybe downsize your lounge suite , wall mount a TV , etc . And then use the existing lounge as dining and family area ? None are ideal , but thats my 'off-the-top-of-my-head' thoughts .
