paddyanne - how I envy you doing a 48 hour turn-a-round for a new kitchen. I have been told to allow two working weeks for mine. Mind you that will involve some changes in plumbing (moving the sink), changes to electricity (new place for oven, and lots of new points), taking down wall-to-ceiling tiling, plastering - as well as all the new units, etc.
Yes, it will be an upheaval. Think it must be worst if there is a family involved - but it is just ME. So, my Dining Table will be opened out, covered and will have my microwave, kettle, egg boiler, toaster, single electric hob, etc on there.
Having my new fridge/freezer delivered and put into that dining area before the work starts - so will have my food store available. Water and sink will be available in my en-suite (bedroom is next to my Living Room). Will take my weekly washing to nearby daughter during that time. Deliberately arranged for mid-May, so that I can go out a lot each day.
In terms of upheaval - it was actually far worse when I had new flooring laid in my Living Room/Diner and my hallway. Had to totally camp out in my bedroom during that time.
As someone has said, we all make our own choices as to how to spend our money. I do not go on holidays - no wish to do so, do not smoke, nor have a car, - my home is my hobby. I am not going into debt - using savings for this work. Once it is finished, I know it will give me an enormous sense of achievement (it is my own design), and I will spend a lot of time admiring it. AND...I know that when the time comes (sooner or later), when my kids have to sell my flat, it will make it all the more marketable.
