Replacing or installing a new bathtub is exciting—but the cost can feel overwhelming. If you’re asking, “How much does a plumber charge to install a tub?” you’re not alone. Many homeowners worry about hidden fees, unexpected labor costs, or choosing the wrong contractor. In this guide, we’ll break down exactly what you’ll pay in 2024, what affects the price, and how to get the best value—without sacrificing quality or safety.
What’s the Average Cost to Install a Bathtub in 2024?
According to HomeAdvisor and Angi (formerly Angie’s List), the national average cost for professional tub installation in the U.S. ranges from $1,500 to $5,000, with most homeowners paying around $3,200.
But that number varies widely based on several factors:
- Type of tub (acrylic, cast iron, fiberglass, freestanding, etc.)
- Labor rates in your region
- Plumbing modifications (moving pipes, drains, or water lines)
- Removal of the old tub
- Permit requirements (required in some cities)
💡 Pro Tip: Labor alone typically costs $400–$1,200, depending on complexity and local rates.
What Factors Affect the Cost of Tub Installation?
Understanding these variables helps you budget accurately and avoid surprises.

2. Location & Labor Rates
Plumbers in New York City or San Francisco often charge $100–$150/hour, while rates in rural Midwest areas may be $60–$90/hour. Always get local quotes.
3. Plumbing Modifications
If your new tub doesn’t align with existing pipes, expect extra costs:
- Moving a drain: $200–$500
- Relocating water supply lines: $300–$800
- Installing a new P-trap or vent: $150–$400
4. Removal & Disposal
Most plumbers include basic removal, but heavy cast iron tubs may incur $100–$300 extra for hauling and disposal.
5. Permits & Inspections
In cities like Chicago or Los Angeles, bathroom remodels often require permits ($50–$300) and inspections. Your plumber should handle this—but confirm upfront.
Step-by-Step: What Happens During Professional Tub Installation?
A licensed plumber follows a precise process to ensure safety, code compliance, and longevity:
- Shut off water supply and drain existing lines.
- Remove old tub (carefully to avoid damaging subfloor or walls).
- Inspect plumbing for leaks, corrosion, or outdated pipes (common in homes built before 1980).
- Prepare subfloor—repair if water-damaged (adds $200–$600).
- Install new tub—level it precisely (even 1/8” tilt causes drainage issues).
- Connect drain & overflow using plumber’s putty or silicone sealant.
- Reconnect water lines with new supply valves (recommended for reliability).
- Test for leaks—run water for 10–15 minutes under full pressure.
- Seal edges with mildew-resistant caulk (e.g., GE Silicone II).
- Clean up and review warranty details.
⚠️ Never skip step #8. A single undetected leak can cause $5,000+ in water damage.

DIY vs. Hiring a Pro: Is It Worth the Risk?
Many homeowners consider DIY to save money—but tub installation is not beginner-friendly.
Pros of Hiring a Plumber:
- ✅ Guaranteed code compliance
- ✅ Warranty on labor (typically 1 year)
- ✅ Proper waterproofing prevents mold
- ✅ Faster completion (1–2 days vs. a weekend + mistakes)
Cons of DIY:
- ❌ Risk of improper slope → slow drainage
- ❌ Leaks behind walls → hidden water damage
- ❌ Voided tub warranty (many brands require pro installation)
- ❌ Time-consuming troubleshooting
📊 Stat: 68% of DIY bathroom remodels require professional correction within 18 months (National Association of Home Builders, 2023).
Unless you have plumbing experience, hire a licensed pro. It’s cheaper than fixing a $4,000 mistake.
How to Save Money Without Sacrificing Quality
You can reduce costs—smartly:
- Choose a standard-sized tub (60” x 30”) to avoid custom plumbing.
- Schedule off-season (late fall/winter) when plumbers offer discounts.
- Bundle services—e.g., install tub + faucet + tile at once for package pricing.
- Get 3+ quotes—but don’t pick the cheapest. Check licenses, insurance, and reviews.
- Ask about financing—many plumbers partner with lenders for 0% APR (e.g., through Hearth or GreenSky).
FAQ Section
Q: How long does it take a plumber to install a bathtub?
A: Most standard tub installations take 4–8 hours. Complex jobs (freestanding, walk-in, or with plumbing reroutes) may take 1–2 full days.
Q: Does tub installation include the faucet and drain?
A: Usually no. The tub itself is separate from fixtures. Confirm whether your quote includes:
- Drain assembly
- Overflow kit
- Faucet and handles
- Supply lines
Q: Are permits required to replace a bathtub?
A: It depends on your city. If you’re not moving plumbing, permits are often unnecessary. But if you alter drain lines or water supply, yes—permits are required in most U.S. municipalities.
Q: Can I reuse my old shower surround with a new tub?
A: Only if the new tub matches the old dimensions exactly. Even a 1/2” difference creates gaps that lead to leaks and mold. Most pros recommend replacing both together.
Q: What’s the cheapest type of tub to install?
A: Fiberglass alcove tubs (sliding into a 3-wall space) are the most affordable—both in material ($250–$600) and labor ($400–$800). They’re lightweight and fit standard bathroom layouts.
Q: How do I verify a plumber is licensed and insured?
A: Ask for their:
- State license number (verify via your state’s contractor board)
- Certificate of insurance (liability + workers’ comp)
- Recent customer references
Never pay more than 10% upfront.
