If ideas of remodeling your current bathroom are in your mind, there are many things to consider first. Your idea of the perfect bathroom design layout should match the size of your floor plans. Ample walking space to move about is also another factor to consider. Strategic placement of the shower or bath, sink and toilet can make or break your re-design. List your flaws in your current bathroom and work from there.A budget is also important, so from your list of things you want to change, your bank roll should dictate what needs to be accomplished first. A simple change in fixtures will cost you around 100 dollars but major remodeling of Tubs, Showers, or Tiles will involve parts, labor and sometimes reconstruction.
