There are many things to consider when preparing for your new floor to be installed. If possible, the current flooring should be removed prior to installation. If you are thinking about replacing a floor, then the amount of sub-floor, or what is under your current floor, becomes very important. Each floor is a special case and has different requirements but a good rule of thumb is to have at least an inch and a quarter of subfloor. This often includes either two layers of plywood or a layer of plywood and one of cement board or similar product. If floor height is an issue, there are products available like Schluter Ditra that are thinner but still very effective.
