Tub to Shower Conversion Cost Calculator

Contractor quotes can feel impossible to compare: one bid hides demolition, another skips waterproofing, and a low number may not include the work that prevents leaks. Use this calculator to build a realistic baseline before you call contractors, order materials, or decide whether DIY is worth the risk.

Why quotes are hard to compare

Two contractors can describe the same project differently. One may include haul-away, waterproof board, glass, and valve work; another may leave those as change orders. The calculator turns those hidden line items into visible choices.
