SO excited about this!
Topps Tiles has this visualiser where you can try out wall and floor tiles.

I've also been playing around with DIY kitchens planner.
planner.diy-kitchens.com/plan/units/
But what I didn't realise you could do was take a picture of your "kitchen" in the planner when in 3D mode (which downloads a screenshot basically) and upload it to Topps Tiles visualiser and play around with the wall and floor tiles.
I am very excited by this!!!!
