Luxury vinyl plank thickness to install?

[Jean Di]

Want to install luxury vinyl plank through out house. What is the minimum thickness I should get? How does 4mm thickness hold up in bath & kitchen?

The thickness you want to pay attention to is the "mil" or "wear layer" thickness, not the actual board thickness. The thicker the wear layer, the longer it will last before it requires replacement. 12 mil is sufficient for most applications. If you're laying it down in a bedroom or something with lower traffic, then you may be safe with as low as 6 mil. 20 mil is better suited for people with kids, animals, or heavy traffic areas. Above 28 mil is typically used in commercial spaces.
