Hello all,

If possible i want the new floor to be the same height as the hallway floor.


I'm remodeling a small bathroom and putting a water proof wood floor down. the new floor will be floating. I've removed the old floor of wonder-board, screws and tile so the sub floor is now exposed.
If I put down plywood that is 5/8" thick on the sub flooring and put the wood floor slats on top of the plywood the floor will be a little over 1/2" above the hallway wood floor that meets the bathroom. If possible I want the new floor to be the same height ( or very close ) as the hallway floor. If I don't put plywood on the sub floor in the bathroom and put the wood slates directly on the sub floor then the two floor levels will be even but I'm not sure putting the wood slates directly on the sub floor is a good idea. That's the only way I can figure out to have both floors the same level but their may be other ways. If you can help me with this please do.

Thanks,
George

There will not be a problem with laying the flooring directly on the existing sub-floor. It is built to support normal weight of living. The important part of the instructions to follow is to make sure that it is fastened with the required fasteners that penetrate the supporting joists. Then you will need to get the floor flat after checking with a straightedge. A long straight piece of flooring can help if you do not have a 6 foot level. Sometimes grinding high spots, then building up low areas with tarpaper is necessary. You will need to get the floor to within an eighth of an inch to flat. Mark with a pencil or chalk.
