Yep, this is what I reckon will be tried too. But then making that robot environment safe for humans to be in will be quite a tough problem.

I imagine things will just be very unified and boring because the same shapes will be recognizable everywhere. But it would be the same things we already have. Just make the robot weak and light enough to not even be able to harm someone. Lighting the kitchen on fire is always a risk though, I guess.

Once the humans in question have paid off the 7 year loan to remodel their kitchen, the real question is what further value do they add to the proposition?

I wasnt thinking Kitchen so much as Data Centre, a lot of whom are already unfriendly to human life, adding 300kg robots, and parts designed for robot interaction are just going to make them even moreso.
