What do you plan to do with the hardwood? Rip it all out? Or do you just want the vinyl at the doors? If you are going to remove hardwood (a financial plus for the value of the home) you might want to replace it with something equally valuable = stone or porcelain.

Vinyl is technically a step down. And it is a real step down. If you cut out areas in front of doors you will want to be aware the vinyl will be MUCH thinner...leaving you with an eyesore for a transition area.

The USA does not produce vinyl flooring because all the chemicals required are produced in China (where the air quality requirements in the industrial cities is calculated in tonnes...not particles).

To ship those chemicals to the USA would be useless. The US wage would create a floor that would be 3times the expense of a solid hardwood floor...you see where I'm going here.

You want to look for VOC free and phthalates free and you want to be able to 'see' the tests on the manufacturer's/seller's website. If you can't see it, then move on. The good guys show their data. The others hide it.

And you want to see documents that are up to date. These chemical analysis reports are valid for 6 months. Yes MONTHS. If you see a document that is from 2017 you know you are working with some of the low-end products (they sell their product SOOOO cheap they can't afford to revalidate their products....sigh).

Untold millions of folks with dogs have hardwood floors and no issues at all.. They go right to an exterior doorway, into a powder room, .............: ) These can be sand on site, or an engineered product. Either is better than LVP , especially in a high end home or even for resale.

If you must do LVP, I would do Fusion Max.

I have been considering LVP for a while and am now starting to really investigate it as I see so many different brands and looks. ( I am chiefly interested in the wood look planks). It looks like Fusion Max is Coretec? Is that correct? Is it a special line as I see Coretec available at many locations but not fusion Max.
