We are adding a new bathroom upstairs. Subfloor is plywood. Hardie board will be installed prior to tile. The vanity will be installed before the tile. Should the hardie board be installed under the vanity too? Or, is it okay to install the vanity on top of the wood floor. I want to make sure the bathroom is waterproofed as well as it can be since our main level is below.
