Replacing a bathtub isnโt just about aestheticsโitโs often a necessity due to cracks, leaks, or outdated fixtures. But before you pick out your dream tub, youโre probably wondering: how much does a plumber charge to replace a bathtub? The answer isnโt one-size-fits-all, but weโll break down everything you need to knowโfrom average costs to hidden feesโso you can budget confidently and avoid surprises.
Whatโs the Average Cost to Replace a Bathtub?
On average, homeowners in the U.S. pay between $1,500 and $5,000 to replace a standard bathtub, including labor and materials. However, this range can swing dramatically based on several factors:
- Type of tub (acrylic, fiberglass, cast iron, etc.)
- Labor complexity (accessibility, plumbing rerouting)
- Geographic location (urban vs. rural, regional labor rates)
- Additional work (tile removal, subfloor repair, waterproofing)
According to HomeAdvisorโs 2023 data, the national median cost sits around $2,800. But luxury installationsโlike soaking tubs with custom surroundsโcan exceed $10,000.
๐ก Pro Tip: Always get at least three detailed quotes from licensed plumbers. A lowball estimate might skip essential steps like code-compliant drain installation or moisture barriers.
What Factors Influence the Total Cost?
1. Type of Bathtub
Different materials come with different price tags:
Fiberglass | $200โ$500 | Low | $1,200โ$2,500 |
Acrylic | $400โ$800 | Moderate | $1,800โ$3,500 |
Cast Iron | $600โ$1,500 | High (heavy, needs support) | $2,500โ$5,000 |
Freestanding | $800โ$3,000+ | Very High | $4,000โ$10,000+ |
Freestanding tubs often require new plumbing lines and reinforced flooringโadding significant labor costs.
2. Labor Rates
Plumbers typically charge $45โ$150 per hour, with most jobs taking 6โ12 hours. In cities like New York or San Francisco, expect rates on the higher end. Some contractors offer flat-rate pricing instead of hourlyโask which is better for your project.
3. Removal & Disposal
Old tub removal isnโt free. Expect to pay $100โ$300 for demolition and haul-away. If your tub is embedded in tile or surrounded by walls, demolition becomes more complexโand costly.
4. Permits & Inspections
In many municipalities, bathtub replacement requires a plumbing permit ($50โ$200). Skipping this may void your home insurance if water damage occurs later. Always verify local codesโWikipediaโs page on building permits offers a helpful overview of why they matter.
5. Unexpected Repairs
Water damage, mold, or rotted subfloors are common behind old tubs. Fixing these issues can add $500โ$2,000+ to your bill. A good plumber will inspect before finalizing the quote.

Step-by-Step: What Happens During a Bathtub Replacement?
Understanding the process helps you spot red flags and plan accordingly:
- Shut Off Water Supply
The plumber turns off the main water line to prevent leaks during disconnection.
- Remove Old Tub & Surround
Tile, drywall, or fiberglass panels are carefully cut away. Debris is bagged for disposal. - Inspect Plumbing & Subfloor
The drain, overflow pipe, and supply lines are checked. The subfloor is examined for water damage. - Install New Drain & Overflow Assembly
This must align perfectly with the new tubโs designโcritical for leak prevention. - Set & Level the New Tub
The tub is placed on a mortar bed (for acrylic/fiberglass) or secured with brackets (cast iron). Itโs leveled to within 1/8 inch for proper drainage. - Reconnect Plumbing
Supply lines and drainpipes are reattached using code-compliant fittings (e.g., P-traps, no-sweat connections).
- Test for Leaks
Water is run for 15โ20 minutes while the plumber checks joints and seals. - Finish Surround & Seal Edges
Tile, acrylic panels, or caulk are applied. All seams are sealed with 100% silicone to prevent moisture intrusion.
The entire process usually takes 1โ3 days, depending on complexity.
DIY vs. Hiring a Plumber: Is It Worth the Risk?
While YouTube tutorials make bathtub replacement look easy, 90% of DIY plumbing fails involve improper drain slope or sealant applicationโleading to mold or structural damage.
DIY Pros:
- Save $800โ$2,000 on labor
- Full creative control
DIY Cons:
- Risk of violating plumbing codes
- No warranty on work
- Potential for costly water damage
Unless youโre a licensed tradesperson, hiring a professional is strongly recommended. A licensed plumber carries insuranceโif they cause damage, youโre protected.
How to Save Money Without Sacrificing Quality
- Choose a drop-in tub: Easier to install than alcove or freestanding models.
- Reuse existing plumbing layout: Avoid rerouting pipes.
- Schedule off-season: Many plumbers offer discounts in winter.
- Bundle services: Replace faucet and showerhead at the same time for a package deal.
- Ask about financing: Some companies offer 0% APR for 12 months.
FAQ: Common Questions About Bathtub Replacement Costs
Q: Does homeowners insurance cover bathtub replacement?
A: Generally, noโunless damage is caused by a covered peril (e.g., burst pipe). Wear-and-tear replacements are your responsibility.
Q: How long does a new bathtub last?
A: Fiberglass/acrylic: 10โ15 years. Cast iron: 30โ50+ years with proper care.
Q: Can I replace just the tub without redoing the whole bathroom?
A: Yes! Many homeowners do โtub-onlyโ swaps. Just ensure the new tub matches the existing alcove dimensions (standard is 60″ x 30″).
Q: Are there eco-friendly or low-water tub options?
A: Soaking tubs use less water than deep models. Look for WaterSense-labeled fixtures if pairing with a shower.
Q: Whatโs the cheapest way to update a bathtub?
A: Refinishing (reglazing) costs $300โ$600 and lasts 5โ7 yearsโbut only works on structurally sound tubs.
Q: Do I need an electrician for a jetted tub?
A: Yes. Jetted tubs require a dedicated GFCI-protected circuit (usually 15โ20 amps). Your plumber will coordinate with an electrician.
Conclusion
Now you know exactly how much a plumber charges to replace a bathtubโand what drives those costs up or down. Whether youโre fixing a leak or upgrading for comfort, getting accurate quotes and understanding the process puts you in control.
๐ก Final Tip: Always verify your plumberโs license, insurance, and reviews on platforms like Angi or BBB. A $200 savings isnโt worth a $5,000 mistake.
