I want to install vinyl flooring in my bathroom. Someone in a DIY shop told me that vinyl flooring requires hard underlay like 1/4 inches plywood. If vinyl flooring sits on top of carpet underlay, vinyl will break. Is that true, or somewhat exaggerated?
On the other hand, having to precisely cut plywood in order to make it fit the intricate shape of my bathroom floor scares me to death. How to cut rigid stuff like this anyway?
