Cost to Replace Tub Shower Combo: Average Prices and Budget Guide

Homeowners are often surprised that the tub itself is one of the smaller line items on the invoice. The real cost to replace tub shower combo units comes from demolition, plumbing, wall repair, and the surround you pick, which is why quotes for the same bathroom can range from $2,500 to more than $12,000. Knowing where the money goes lets you compare bids fairly, decide where to spend, and avoid the change orders that hit when a contractor opens a wall and finds rotted subfloor. Below are realistic 2026 prices by material, scope, and region.

Average Cost to Replace Tub Shower Combo

Nationally, most homeowners spend $4,000 to $8,000 to replace a standard 60 x 30-inch tub and shower combination with new walls, valve, and trim. Basic one-piece or multi-piece acrylic replacements land near the low end, while tile surrounds, cast iron tubs, and glass doors push the total higher.

These figures assume the drain stays in the same location and the framing is sound. Moving the drain, enlarging the alcove, or repairing water damage adds to the total.

Cost Breakdown by Component

Breaking the job into its parts is the most useful way to judge a quote. Here is where a typical mid-range budget goes:

• Demolition and disposal: $300 to $900. Cast iron tubs weigh 250 to 350 pounds and often must be broken up with a sledgehammer, which adds labor.
• New tub: $250 to $600 for fiberglass or acrylic, $400 to $1,000 for enameled steel, $800 to $2,500 for cast iron.
• Surround or wall material: $300 to $1,500 for a kit, $1,000 to $3,500 for solid-surface panels, $1,500 to $5,000 for tile installed.
• Valve and trim: $150 to $600 for parts, plus $200 to $500 for plumbing labor.
• Backer board and waterproofing: $200 to $600 for cement board, foam board, or a membrane system.
• Glass door or rod: $30 to $150 for a curtain rod, $400 to $1,500 for framed or frameless glass.
• Drywall, paint, and trim repair: $200 to $700 outside the wet area.

Labor usually accounts for 40 to 60 percent of the total. Rates range from $50 to $120 per hour for general remodelers and $80 to $150 per hour for licensed plumbers, depending on region.

Tub and Surround Material Costs Compared

Fiberglass and Acrylic Units

One-piece units, $400 to $1,200, have no seams and install fast, but they rarely fit through a finished bathroom doorway, so they are best for new construction or major remodels where a wall is opened. Multi-piece acrylic systems, $600 to $2,000, fit through doors and are the most common replacement choice. Acrylic holds heat better and resists scratches more than gelcoat fiberglass.

Enameled Steel

Steel tubs cost $400 to $1,000, feel more solid than fiberglass, and resist scratching. They are noisier and colder to the touch, and the enamel can chip if a heavy object is dropped.

Cast Iron

Cast iron tubs, $800 to $2,500, are the most durable and retain heat for a long soak. The weight requires two or three installers and sometimes floor reinforcement in older homes with 2×6 joists.

Tile Surrounds

Ceramic or porcelain tile runs $10 to $30 per sq ft installed. A standard alcove has about 70 to 90 sq ft of wall area to 7 feet high, so tile surrounds typically total $1,500 to $4,500. Large-format porcelain panels reduce grout lines and cost more per sq ft but less in labor.

Solid-Surface and Cultured Stone Panels

Grout-free panels, $1,500 to $4,000 installed, offer a high-end look with easy cleaning and are increasingly popular in tub replacements.

Hidden Costs That Change the Final Price

Most budget blowouts come from what is behind the old tub. Get these possible add-ons into writing before work starts.

• Subfloor or joist rot: $300 to $2,000 depending on how far damage extends.
• Mold remediation: $500 to $2,500 if mold is found inside walls.
• Drain relocation: $500 to $1,500, more on slab foundations where concrete must be cut.
• Old supply lines: Replacing galvanized or polybutylene pipe to the valve adds $300 to $1,200.
• Non-standard sizes: Tubs shorter than 60 inches or wider than 32 inches often cost more and may need special order.
• Permits: $100 to $500 in most jurisdictions when the valve or drain is replaced.
• Floor tile repair: New tubs may have a different footprint than old ones, exposing gaps in the existing floor tile. Budget $300 to $1,500 for patching or retiling the bathroom floor.

When to call a licensed professional: valve replacement, drain changes, and any work on supply lines should be done by a licensed plumber, and many cities require a permit and inspection. If a cast iron tub is going into a second-floor bathroom or an older home, ask a contractor to confirm the floor framing can carry roughly 800 to 1,000 pounds when the tub is filled and occupied.

Replacement Versus Refinishing, Liners, and Conversions

Full replacement is not the only choice, and the right option depends on the condition of your tub and walls.

Refinishing lasts 5 to 15 years and cannot fix leaks or rot. Liners are installed in a day, but they cover existing problems rather than fixing them, and a poorly sealed liner can trap moisture. If you have any sign of water damage, such as soft flooring around the tub, stains on the ceiling below, or loose tile, full replacement is the safer investment.

Regional and Labor Factors

Where you live changes the total significantly. Remodel labor in major metros such as New York, Boston, San Francisco, and Seattle can run 25 to 50 percent above the national average. Rural areas and parts of the South and Midwest often come in 15 to 25 percent below it. Condos and apartments add costs for elevator reservations, protected hallways, and restricted work hours.

Timeline also affects price. A straightforward acrylic replacement takes 1 to 3 days. A tile surround requires 4 to 7 days because of backer board installation, waterproofing, tile setting, grouting, and cure time. Rush scheduling or weekend work can add a premium of 10 to 20 percent.

One more timing factor is material lead time. Stock acrylic tubs and kits are usually available within a week, but cast iron tubs, specialty colors, and custom-cut glass doors can take 3 to 8 weeks to arrive. Glass enclosures in particular cannot be measured until the walls are finished, so most installers return 1 to 3 weeks after the tile is grouted to template and install the door. Order the tub and valve before demolition starts so the bathroom is out of service for as few days as possible, and confirm the rough-in valve brand matches the trim kit you picked, since mixing brands is a common cause of return trips and extra labor charges.

How to Save on Your Tub Shower Replacement

1. Keep the drain and valve locations. Moving plumbing is one of the biggest cost multipliers.
2. Handle demolition yourself. Removing tile and drywall can save $300 to $700, but leave the tub removal and plumbing disconnects to the pro if you are unsure.
3. Choose a standard 60-inch alcove tub. Stock sizes are cheaper and faster to get.
4. Tile only to 6 or 7 feet. Tiling to the ceiling looks great but adds 15 to 25 percent more tile and labor.
5. Use a curtain instead of glass. This saves $400 to $1,500 and can be upgraded later.
6. Get three itemized bids. Ask each contractor to list demo, tub, surround, plumbing, and contingency separately so you can compare apples to apples.
7. Schedule in the off-season. Late fall and winter often bring better availability and occasionally lower prices.

With a clear breakdown of materials, labor, and likely hidden costs, you can set a realistic budget and hold contractors to it. For most homes, the cost to replace tub shower combo installations with a quality acrylic or tile surround lands between $4,000 and $8,500, a worthwhile investment for a bathroom that will not leak or look dated for the next 20 years.
