Thinking about upgrading your bathroom with a new bathtub—but unsure what it’ll cost? You’re not alone. Many homeowners hesitate because they don’t know how much a plumber charges to install a bathtub—and fear hidden fees or budget overruns. The good news? With the right info, you can plan confidently, avoid surprises, and even save hundreds. Let’s break down everything you need to know, from average costs to what influences pricing.
What’s the Average Cost to Install a Bathtub?
On average, a plumber charges between $400 and $1,800 to install a standard bathtub in the U.S., according to data from HomeAdvisor and Angi (2023). However, total project costs—including the tub itself, labor, and materials—typically range from $1,200 to $8,000+, depending on several key factors.
💡 Pro Tip: Labor alone usually accounts for 30–50% of your total bathtub installation cost.
What Factors Affect Bathtub Installation Costs?
Several variables influence how much you’ll pay. Understanding them helps you estimate more accurately—and negotiate smarter.
1. Type of Bathtub
Different tubs require different installation efforts:
Acrylic
$200 – $800
Low
Fiberglass
$250 – $900
Low
Cast Iron
$500 – $2,500
High (heavy, needs support)
Freestanding
$800 – $5,000+
Medium–High (plumbing reroute)
Whirlpool/Jacuzzi
$1,000 – $8,000+
High (electrical + plumbing)
Freestanding or jetted tubs often require additional plumbing rerouting or electrical work, which increases labor costs.
2. Removal of Old Tub
If you’re replacing an existing tub, removal adds $100–$300 to your bill. Tile or built-in surrounds may require demolition, raising costs further.
3. Plumbing Modifications
Need to move drains, water lines, or vents? That’s $200–$1,000+ extra. Older homes often need pipe upgrades to meet current codes.
4. Location & Accessibility
Installing a tub on an upper floor or in a tight space may incur higher labor fees due to logistical challenges.
5. Permits & Inspections
Some municipalities require permits for plumbing changes. These cost $50–$300, but skipping them risks fines or failed home inspections later.
How Much Do Plumbers Charge Per Hour?
Most plumbers charge $45 to $200 per hour, with the national average around $90/hour (U.S. Bureau of Labor Statistics, 2023). Master plumbers or those in high-cost cities (e.g., New York, San Francisco) often charge more.
⚠️ Note: Many plumbers offer flat-rate pricing for bathtub installations instead of hourly billing—this protects you from unexpected overtime charges.
Step-by-Step: What Happens During Bathtub Installation?
Knowing the process helps you verify quality work and avoid being overcharged.
Assessment & Planning (Day 1) The plumber inspects your space, checks water lines, drain location, and subfloor condition. They’ll confirm if your floor can support heavier tubs (e.g., cast iron weighs 300+ lbs!).
Remove Old Tub & Prep Area (2–4 hours) Old tub is disconnected, removed, and debris hauled away. Any damaged subfloor or wall studs are repaired.
Install New Plumbing (If Needed) Adjust drainpipe slope to ¼ inch per foot for proper drainage. Install new shut-off valves if required.
Set & Level the New Tub (1–2 hours) The tub is placed, leveled with shims, and secured. For alcove tubs, flanges are sealed to wall studs.
Connect Water Supply & Drain Flexible supply lines (usually ½-inch) are connected. Drain assembly is tested for leaks.
Final Inspection & Cleanup Plumber runs water to check for leaks, ensures proper drainage speed (should empty in under 90 seconds), and cleans the work area.
📌 Expert Insight: “Always test the tub before tiling or finishing walls. A leak discovered post-renovation can cost 3x more to fix.” — Maria Lopez, Licensed Master Plumber (CA)
Voided tub warranty (many require pro installation)
Costly repairs if pipes are damaged
🛠️ Reality Check: A botched DIY install can lead to $2,000+ in water damage repairs—far exceeding plumber fees.

FAQ: Common Questions About Bathtub Installation Costs
Q: How long does it take a plumber to install a bathtub?
A: Most standard installations take 4 to 8 hours (1 day). Complex jobs (e.g., moving plumbing, custom tubs) may take 2–3 days.
Q: Does bathtub installation include the faucet and drain?
A: Usually no. Fixtures like faucets, overflow drains, and showerheads are often sold separately. Confirm with your plumber whether they’re included in the quote.
Q: Can I reuse my old plumbing for a new tub?
A: Sometimes—but only if the new tub matches the old one’s dimensions and drain location. Even then, older pipes may need replacement for safety and efficiency.
Q: Are there hidden costs I should watch for?
A: Yes. Watch for charges like:
Haul-away fees for old tub ($50–$150)
Tile removal or wall repair
Emergency or weekend service premiums (up to 50% extra)
Q: Does homeowners insurance cover bathtub installation?
A: No—installation is considered a home improvement, not a covered loss. However, damage caused by faulty installation may be covered if it leads to sudden water damage.
Q: How do I verify a plumber is licensed and insured?
A: Always ask for:
State license number (verify via your state’s contractor board)
Proof of liability insurance and workers’ comp
Recent references or online reviews (check BBB or Google)
