Our house is an earth contact home with the first floor being concrete floors. We have very high and low humidity in the house, in the summer it can be 70% without running the dehumidifier and as low as 10% if we run the fireplace in the winter. The bamboo flooring that we are replacing buckles and makes mountains in the summer without the dehumidifier and all of it cupped within 3 months of installation or less. It was installed April - June 2016.

We now get to replace our floors as my children ran so much water in their bathroom it flooded my office. I've had the relative humidity checked and it was 70.4% in my office and 79% under the stairs. That has made us come to the conclusion that we have to go with an LVP and can not do engineered wood like I wanted. Also keep in mind that our concrete floors are not level. We went through 18 bags of leveler 3 years ago to put in the bamboo and it still needs and will get more before we put the next floor in.

It has been suggested that we need to glue down the floor no matter what if we don't want it to fail. However all of the installers think that floating is best. I'm looking for another opinion from the experts who see what fails.

Also I want to get your opinion on Southwind Classic Strip Colonial Maple lvp flooring. This is the perfect flooring color, texture, and wood graining for my house. However, I do have concerns on it's manufacture and my asthma with allergies to many chemicals. The only chemical I've for sure concluded I'm allergic to is formaldehyde, but it isn't the only one. I did have some issues with the Laminate floors we installed in our old house. If you think this is a poor choice, do you have any suggestions for a similar color and width of flooring?

Thank you so much for your help and insight!

No matter what floor you install, the sub-floor needs to be flat.
Vinyl plank will work very well and a floating floor might be best if you have concrete moisture issues as you put down a plastic moisture barrier then lay the plank on top of the moisture barrier.
I would also suggest ceramic tile as it is more moisture resistant.

Inspectors do not recommend brands for quality, however, to answer your questions on the product for your home and based on your slab and environmental conditions an LVP or wood product may not be your best option. Your slab does not have to be level it needs to be flat to 3/16" on 10 foot. Self-level can achieve this condition. With the wide swings in your relative humidity, your best option for a new floor would be some type of ceramic tile. They make many wood looking plank tiles. The key is to get your substrate flat to standards
