Sink, tub, and shower fixtures to be removed and replaced with new ones
Solution: Do they functionally need to be replaced or just aesthetically? They may be ugly but operable, and can be replaced easily by yourself at a later time. If that fails, buy on your own and supply to contractor. Or instead of replacing, you can
install a liner over your tub or shower. If you don't like the idea of a liner, you can always
refinish your bathtub.
