The average price to reglaze a standard bathtub is about $300 to $400 as of 2015. This is a much more affordable option than purchasing a new tub, because removing the old tub usually requires a complete remodeling of the bathroom.
On average, the materials and supplies for reglazing a bathtub range from $63.72 to $73.26, as of 2015. Most of the cost of reglazing is from the labor involved, which includes prepping the bathroom to prevent dust from getting all over and ventilating to make sure homeowners don't breathe in fumes. Contractors also sand the old finish and repair chips and cracks before applying a primer, new surface and top coat to the tub.
