There are ways to save in a bathroom remodel. Some bathroom remodels can get away without replacing the tub. Consider having the tub reglazed and save yourself the labor and materials of having the heavy item demolished and removed and a new one put in its place.
At one estimate, the costs can be halved. There are many fiberglass surrounds that will provide you with a great looking shower without the labor intense tile option. They are also easier to clean.
