What drives the price
Three decisions set most of the budget: the wall system (prefabricated surrounds are the economical route; custom tile costs more but is fully tailored), plumbing changes (reusing the existing drain location is cheap; moving drain lines runs roughly $900–$1,100 and relocating supply lines adds $700 or more), and glass (framed doors about $400–$1,200; frameless $1,200–$3,000).
Cost figures reflect published 2026 planning ranges from HomeGuide, Angi, and This Old House; actual quotes vary by home, materials, and provider scope.
Hidden costs to plan for
In a 2026 survey, about 70% of homeowners hit unexpected costs during conversions — most commonly structural repairs (38%), water damage discovered behind the tub (32%), or unplanned plumbing upgrades (29%). A provider who inspects before quoting, and states how surprises are priced, is protecting you.
- Ask how change orders are priced before work begins
- Ask whether demo findings pause work for approval
- Keep a 10–15% contingency on top of the quote
Compare scope, not just price
A low quote that excludes tub disposal, waterproofing warranty, or glass is not a low price — it is an incomplete one. Ask every provider to list inclusions the same way so quotes line up.
