In my past renovations, it's been unforeseen things numbering too high, too often, blowing out the budget and time frame! That was after me allowing for some things in advance too! This time I'm concentrating on structural before moving in, then taking my time over a year or two to do a few things at a time, so there's less rush. Eg Restumping, dangerous tree removal & roof repairs before moving in, then once in, kitchen, skylights, ducted climate control, landscaping, verandas & bathrooms all separately with a break in between, rather than all at once! Means it's gentler on my psyche and my wallet, plus allows me to plan each thing through more thoroughly as I'm only concentrating just on that thing. Fortunately it's just renovating existing spaces and not an extension (that's in about 4-5 years!) Good luck and remember to get out often for nights away!

The penny rubber flooring yes and it's great, I think anything with a rough surface will collect dirt. You can get a commercial lino that looks like granite etc that also looks good and doesn't have a polished surface

Tiles will need a very stable base to avoid cracking if the house subtly moves. We’ve had a couple of very solid floor tiles break after minor impacts in our pre 1947 Qld home. Laid in the bathroom, to code, but still fine cracks in a couple of places. All doable on timber floor, but not as straight forward as laying on a concrete slab. (I love cork for all these reasons and it doesn’t have to be scarey orange anymore. Very flexible and durable but I know I’m firmly in the minority with that one!)

This is an ideal situation for a very short toilet. why do so many of them stick out from the wall SO far. Here it would be great if the loo was minimum eg. 450 from wall so as you can get past it easily. Yes you can use an in wall cistern but often the pan is still sticking out like a sore thumb. I would love to see a loo that is no further out than a vanity: neat, tidy discrete.
