I tore the carpet out of my bathroom and have vinyl tile to put down. there is a lip from the toilet/sink surround that pokes out about an inch over the plywood flooring.
If I replace the round headed screws that hold it down with flat heads, and tile over it, any problem? I think the tile is resilient enought where the slight lip height will not show.
Thankfully the wood is in great shape, no rot.
