Your remodeling ideas should start with a rough plan. Making a list of what displeases you, and that you want to change is a good place to start. List the amenities you want to add.

If your bath design includes simply replacing the fixtures and cabinetry in your existing bathroom and staying with the same dimensions and placement your  remodeling design should be fairly simple. However, if your bathroom remodeling ideas include changing the sizes of units such as vanity, bathtub, shower, etc. or changing placement then you will need a more exacting plan. 

If you are enlarging your bath area then we will need to re-plan and measure accurately to make sure everything you want will fit. You may find that you need to re-arrange things in the space you have to make it more useable. It' s much like moving the living room furniture. Sometimes different placement works better even though you have the same items in the same amount of space. Moving something may make the whole plan just work better and the space more convenient and usable. As with any remodeling project take time to think how the members of your household use your bathroom. Start there and then think about what would make it better for your household and factor this into your bathroom remodeling ideas.
