The proposed bathroom has a raised terrazo floor where the toilet used to be.
If you aren't familiar with terrazo it is a speckled concrete floor laid quite thickly straight onot the hardwood floor. It is reasonably unattractive..... alright very unattractive!
Apparently from my research this would have to be jackhammered out, not cheap and doesn't always end well with the floor having to be replaced.
So options as I see them:
1. Jack hammer it out with the possibility of replacing the floor - not cheap!
2. Raise the whole floor level to meet the terrazo platform - a definite possibility.
3. raise just the section across the back of the bathroom where the bath will be to step up to it - not sure whether this would look ok?
4. Or tile over it as a raised platform under the bath and run the bath across the corner on the platform like this image, we could add two windows and have a similar style - worried about how it would end up looking?
