Hard flooring fitted with minimum disruption

Can anyone offer advice on flooring that can be fitted with minimum disruption?

I want to replace my carpets with solid flooring.
The carpets have to go because the dust they create is making my wife's medical condition worse.

We live in a bungalow with concrete floors.
We currently have fitted carpets over thermoplastic tiles dating from the 1960's.

I like the idea of the solid vinyl tiles like Amtico
The salesman tells me the floor will need to be prepared with a quick-drying, self-levelling screed.

Now here's the problem:

Due to my wife's health, I'm gonna find it very difficult to have parts of the house out-of-bounds while they do the preparation.
We only have one loo and one bedroom.

Anyone have experience of what it's like to have this done? Please note that, apart from my wife's poor health, I'm 66 now and getting a bit of a delicate sad old git ...... We really do need a quick and easy process with the minimum of disruption.

Are there any types of hard-flooring that cope with an uneven surface better than the Amtico type vinyl tiles?

 

Thanks for the advice - sounds like the best solution with the least disruption.

What's the situation with 'floating' laminate in a bathroom? Is it as water-resistant as stick-down, Amtico-type vinyl tiling?

Also, is laminate noisier than the tiles?
