Tub to Shower Conversion Cost (2026): Kit, Stock, Tile & Accessible Walk-In

Converting a tub to a shower typically costs $1,500 to $8,000, with a national average near $3,000, per HomeAdvisor and Modernize. A prefab kit sits at the low end ($1,200-$8,000); a custom-tiled or accessible walk-in shower can run $3,500-$15,000+ once plumbing relocation, tub removal and premium finishes are added. Use the estimator below to build your own range.

Pick the shower type you're converting to, whether the plumbing needs to move, how much tub-removal and wall repair the job needs, and your finish level. The result is an installed-cost range built from two independent published sources, not one contractor's marketing figure.

$1,350 – $8,800

Estimated installed cost for your selections, before local quotes.

This range covers the shower unit or tile system, standard installation labor, and the plumbing/removal options selected above. It does NOT include: a full bathroom remodel beyond the tub/shower footprint, permits (HomeAdvisor cites $200-$2,000; Modernize cites a narrower $100-$300 — check with your local building department, since this is the one line item where the two sources disagree most), a new vanity/toilet/flooring, or accessibility add-ons like grab bars ($50-$500 each) and a fold-down seat ($100-$600) if not already part of your accessible walk-in selection. Get at least three itemized written quotes — the finish-level multiplier here is directional, not a substitute for a per-square-foot material quote on your specific size.

What a tub-to-shower conversion costs, by type

HomeAdvisor puts the "normal range" for a tub-to-shower conversion at $1,500-$8,000, with a national average around $3,000 and a full spread of $1,200-$15,000+ depending on scope. Modernize's independent breakdown by shower style lines up closely: pre-fabricated kits $1,200-$8,000, corner units $1,500-$6,000, framed showers $1,800-$6,500, walk-in showers $2,500-$15,000+, semi-frameless $2,800-$8,000 and frameless $3,500-$12,000+. The type of shower you choose moves the price more than any other single decision.

Prefab kit vs stock shower vs custom tile vs accessible walk-in

A prefabricated kit — a one-piece or multi-panel fiberglass/acrylic pan and surround bought at a home-improvement store — is the cheapest and fastest option, per both HomeAdvisor's shower-stall pricing ($1,000-$8,000) and Modernize's pre-fab figure ($1,200-$8,000). A stock corner or framed unit splits the difference at roughly $1,500-$6,500 (Modernize). A fully custom-tiled shower costs more per square foot but lets you set exact dimensions — HomeAdvisor's tiled-shower total runs $900-$10,000 depending on tile grade. An accessible, curbless walk-in shower — no threshold to step over, built for aging-in-place or mobility needs — sits at the top of the range, $3,500-$15,000+ per HomeAdvisor's custom-tiled walk-in figure and Modernize's walk-in category, since it typically needs a lowered or reframed floor in addition to the shower itself.

Plumbing relocation: the line item that varies most

If your new shower sits in exactly the same footprint as the old tub, plumbing work is minimal. Move the drain or shift the supply lines to a different wall, though, and both HomeAdvisor and Modernize independently cite the identical figure: $300 to $2,400 for plumbing adjustments. That agreement across two unrelated sources is a strong signal this is a real, not padded, cost — ask your contractor to itemize it separately from the shower installation labor.

Tub removal and what's hiding behind it

Taking out the old tub is rarely the expensive part on its own: Modernize prices bathtub demolition, removal and disposal at $150-$800, and HomeAdvisor's narrower removal-only figure is $150-$300. What drives cost up is what the removal uncovers — water damage, rotted subfloor, or wall studs that need replacing. HomeAdvisor bundles removal plus wall prep and minor repair at $450 to $2,000, which is the realistic number to budget if your bathtub has been leaking or the caulk line has failed for any length of time.

Finish level: fiberglass, tile, or natural stone

Material choice is priced per square foot and swings the total more than most homeowners expect. HomeAdvisor's per-square-foot figures: fiberglass/acrylic $0.75-$12, ceramic/porcelain tile $1-$17, cultured marble $10-$35, cultured granite $40-$64, and quartz $50-$100 — a roughly 8-to-130x spread between the cheapest and most premium material for the same square footage. Because labor and the shower base/plumbing lines don't scale at the same rate as the wall material, the finish multiplier in the estimator above is intentionally more moderate than that raw per-square-foot ratio would suggest — treat it as directional and get a per-square-foot material quote for your exact shower dimensions.

Tub to shower conversion kit cost: the DIY-adjacent option

A "conversion kit" specifically usually means a prefabricated pan-and-surround system designed to drop into a standard tub's footprint without custom framing — the low end of the prefab-kit range above ($1,200 and up for the materials plus professional installation). Kits alone (materials only, no labor) are typically a few hundred to low-thousands of dollars depending on size and brand; the installed price in this estimator already assumes professional installation labor, which HomeAdvisor and Modernize both note runs 40-60% of the total project cost, since a leak-tight shower pan and surround is not a forgiving DIY project.

Tub to shower conversion near me: getting quotes you can compare

"Near me" pricing depends on local labor rates and which contractors specialize in one-day conversions versus full bathroom remodeling. Get at least three itemized quotes and make sure each one specifies: conversion type, whether plumbing moves, tub-removal/wall-repair scope, and finish material — a bid that's missing one of those line items is hard to compare fairly against another. If this conversion is part of a bigger remodel or aging-in-place project you're financing, the loan calculator can help you check monthly payments before committing, and if hard water is part of why your old tub and fixtures look worn, it's worth checking the water softener cost page too.

Frequently asked questions

How much does a tub to shower conversion cost?

Typically $1,500-$8,000, with a national average around $3,000, per HomeAdvisor. Modernize's independent estimate agrees closely: $1,200-$15,000+ depending on shower type, size, plumbing changes and finish material.

How much does a tub to shower conversion kit cost?

A prefabricated kit — pan plus surround designed to drop into a standard tub footprint — starts around $1,200 installed and runs up to $8,000 depending on size and brand, per Modernize's pre-fabricated shower category. Materials alone (no labor) are typically a fraction of that.

How do I find a tub to shower conversion near me at a fair price?

Get at least three itemized quotes specifying conversion type, plumbing relocation, tub-removal/wall-repair scope and finish material. Local labor rates and whether a contractor specializes in one-day conversions vs full remodels both move the price.

Should I replace my tub with a shower?

It can modernize the bathroom and improve accessibility, often with a strong return on investment, per HomeAdvisor — but if it's the only bathtub in the home, removing it may affect resale value for buyers who want at least one tub. Consider your long-term plans before converting your only tub.

Is it cheaper to install a shower or a tub?

Showers cost slightly more on average to install than tubs — HomeAdvisor cites $2,000-$9,400 for showers versus $2,400-$8,800 for tubs — though the gap depends heavily on materials, size and features chosen for either.

How long does a tub to shower conversion take?

Generally one to three days, per HomeAdvisor. A prefabricated one-day conversion is fastest; custom tile work or plumbing relocation extends the timeline.

What's the difference between a shower stall and a custom shower?

A prefabricated shower stall is less expensive and faster to install but comes in a limited set of standard sizes and styles. A custom shower lets you set exact dimensions and choose any tile or stone finish, but costs more and always requires professional installation.

Does moving the plumbing add much to the cost?

Yes — both HomeAdvisor and Modernize independently cite $300-$2,400 for relocating a drain or supply line to a new position, versus close to $0 extra if the new shower reuses the tub's existing plumbing footprint.

What if there's water damage behind my old tub?

Budget for it before you get a quote: HomeAdvisor bundles tub removal plus wall prep and minor repair at $450-$2,000, versus $150-$300 for removal alone if the walls are in good shape. Ask the contractor to inspect before finalizing a fixed-price quote.

Do I need a permit for a tub to shower conversion?

It depends on your local building department. HomeAdvisor cites $200-$2,000 for bathroom permits generally; Modernize cites a narrower $100-$300 for this specific project. Confirm with your city or county, since the two published figures disagree meaningfully.
