the bathroom looks about 1800 x 2700 which is wide enough for a super wide walk in shower 1800 x 900) across the room and double handbasin (1500-1800x 500) along the old bath wall with mirror doored wall cabinets above the vanity and there should be plenty of wall space for towel railsconsider wall hung vanity to allow floor space under the vanity for waste bin, scales, slippers etc and makes the room look more spacious

EVERYTHING looks 50 years old . I'd be tempted to rip out the front fence , the shrub/trees , the sloping pathway , the wrought iron , the carport , the gate to the left , probably the boundary fences , and start again . Even the lawn looks like cows have grazed there for 50 years -- if you have the budget , get readylawn laid , or hire a rotary hoe and have a go yourself with grass seed . Do some modern gardens along under the windows , maybe rock or bark as a base , leafy green plants , brown grasses , yellow leaved plants , red plants that aren't roses ( cause they are more than 50 years old ! ) . Do some charcoal fences around the sides , pretty much whatever you want along the front . Maybe the standard white picket fence -- still works , pretty cheap . The think , what is one thing to give a Wow -- a point of difference ? Thats where you get creative . Maybe a modern sculpture , maybe a willow tree , maybe a water feature . NOT a bird bath , or a frame or arch with a climbing rose . Please don't do them .

my suggestions includes moving the sliding glass doors into the dining room, has a small walk in pantry and open scullery to avoid blocking the new window, keeps the separate entry foyer wall (to help support upstairs) adds a vanity to the powder room, removes the extra shower to make the laundry more functional and reversing the stairs (depending on upstairs floorplan) would make for easier access for moving furniture, adds more light from the stairwell into the entry foyer and the under stairs storage space could be included in the bathroom for more space but all suggestions depend on accurate dimensions

Hi Me, It's been 10 months, I hope that you have sorted it out. I like the idea of keeping the toilet separate as it will increase not only the aesthetic but also the hygiene and privacy of the main bathroom. It might be better if you can convert the swing door into a cavity door, which will help you have more ample space for comfort. In case you don't want to keep the toilet in a completely separate area, just don’t want it to be easily seen, consider adding a half wall is another great option.
