We used Caesarstone Statuario Maximus on our island bench, Caesarstone Snow on our counter top and backsplash and Dulux Whitsunday Island half strength in satin finish for our cabinetry. The cabinetry and Snow are seemless in colour. Statuario Maximus tones in well with the cabinetry. The staff at Caesarstone had suggested Fresh Concrete for to match SM but we felt we needed a stone to match the cabinetry. We painted our whole house in Whitsunday Island half strength and love it. Our aspect is East and we have blaring sun in the morning and shade for the remainder of the day and found that Whitsunday Island half strength was the only colour that balances the yellow sun and blue shade.

There's a fair bit of information here: http://www.fibonaccistone.com.au/are-your-floors-safe-and-hygenic/ hope it helps!

How do you know that the hallway would of been through the middle of the home. A lot of California bungalows had the bathroom directly in line with the front door. Standard four front rooms, consisting of two bedrooms, lounge and kitchen with table in the middle of the kitchen. I remember growing up with my grandparents having exactly that. There home was built in 1932 the similar period as yours. So I don’t think the owners botched the extension, they just utilised the existing bathroom as a WIR, and installed all new plumbing in the new rear extension. It would of been a cheaper option. With the fireplace in your master bedroom in the room on the back left, that would of been the kitchen/diner. This plan is an original home currently for sale, which has not changed since built in 1930, it still does not have an inside toilet.
