Tub-to-Shower Conversion Cost Guide

Evidence note: project cost ranges are editorial planning allowances, not observed contractor-bid averages. Contextual references do not independently establish every allowance. Confirm the complete scope with local written quotes.

A professional tub-to-shower conversion commonly needs a $6,500–$16,000 planning allowance. Prefabricated surrounds are usually lower; custom tile, curbless work, drain relocation, and concealed repairs increase cost.

Planning guidance for professionally completed US projects. Local quotes, site conditions, material selections, permits, and access determine the actual price and schedule.

What the conversion includes

The work normally includes tub removal, plumbing adjustment, wall preparation, a new shower base or tiled floor, waterproofing, wall finish, valve trim, enclosure, and accessories.

Tub and surround demolition
Drain size, position, and trap access
Valve replacement or height adjustment
Shower base and waterproofed wall assembly
Door, curtain, or custom glass enclosure

Common surprises

Water damage, undersized or poorly located drains, out-of-plumb framing, failed subfloor, and old valves frequently appear after demolition. Curbless conversions may require structural or slab work that a surface-only quote does not include.

Resale and household needs

Consider whether another bathtub remains in the home and who will use the room. A shower can improve daily access, but the best layout balances entry, controls, storage, splash containment, and future household needs.
