There are many designs similar on ebay if you type Victorian floor tiles, a vast array of patterns and styles will come up with some more ostentatious than others. Hope this helps.

You're the customer so have it how you want. Its more expensive to tile wall to wall which is why lots of kitchens are only tiled up to the legs, but its getting more and more popular to have the kitchen fully tiled before fitting like they do on the continent. When we have a kitchen to fit and its been tiled we lay hardboard over the floor to protect it, so it is an extra small cost. Accidents can happen though like dropping the oven but that could of been an old existing tiled floor that could be chipped and no replacement tiles available. Also its harder for your fitter to install as he has to scribe and seal all your decor panels to the floor when its been tiled is another reason installers prefer it to be tiled afterwards.

I love your floor as it is but appreciate you need to change the kitchen part. Have a look at Claybrook studio, they have some beautiful tiles. I hate laminate everywhere. It would put me off buying a house but thats just me. If you change all the flooring then I would definitely try and use wood or engineered wood. I don't know how long you are planning to stay there or your budget but I would seriously think twice before ripping up pine floors to replace with laminate or LVT. I have engineered oak everywhere. Not my choice but nice to live with as it looks warm. You could refinish your pine floors everywhere else with white oil after sanding and stripping. It would look amazing. I did it years ago. No one would believe it was the same floor. If you decide on a laminate and some are very tempting I would try and keep it in the kitchen only. Your console sounds lovely.

Try any carpet shop or fitter, independent if possible, as they often sell sheet vinyl too. I used an independent carpet fitter who brought round books of sheet vinyl and there was a great selection. I chose this pattern for my little bathroom but there are tons of designs. He was recommended to me.
