Short answer
Pick your job and any extras, and the estimator adds up national installed ranges from published 2026 cost guides. For example, a prefab walk-in shower kit runs about $2,000 to $5,000 installed (Modernize, 2026). Adding a glass door ($550 to $1,400, Angi 2026) raises both ends. It is a starting range, not a quote.
Key facts
Estimate your shower or bath project
Pick the job and anything it also needs. You get a national range from published cost guides, not a quote.
What the estimator covers
Nine jobs: a prefab or custom tile walk-in shower, a curbless shower, a tub to shower conversion (prefab stall or custom tile), a shower to tub conversion, a walk-in tub, and a small or master bathroom remodel. Seven extras: a glass door, a grab bar, a fold-down seat, moving plumbing, custom tiling, a permit, and demolition and removal of the old tub or shower.
How the ranges are built
Each job and each extra is one installed range taken from a single published cost guide, and the result table names that guide and its update month under every line. When you tick an extra, its low figure is added to the job's low figure and its high to the high. Nothing is averaged or adjusted for your city.
Main sources: Modernize for walk-in showers and demolition[1]; This Old House for tub to shower conversions, curbless showers, grab bars and seats[2]; Angi for glass doors, permits, shower to tub conversions, plumbing moves and master bathrooms[3][4][5]; Fixr for walk-in tubs[6]; and HomeGuide for small bathrooms and custom tiling[7][8].
Read the result with care
- Extras can overlap. Many quotes already include demolition, a permit or a door. Ticking them again can double count.
- Guides disagree. We use one guide per line so the math is clear. The cost pages show the other guides' ranges side by side.
- Local prices differ. Labor rates, access and hidden water damage move the real number.

When to call a pro
- To turn a range into a price, get at least two written quotes for your bathroom.
- Have a licensed plumber confirm whether the drain or valve must move before you compare quotes.
