  • How Much Does It Cost To Install A Bathtub

When considering a bathroom renovation or new build, one of the most common and impactful upgrades is installing a bathtub. Whether for relaxing soaks or practical use in family homes, a tub is a central feature in many bathrooms. Understanding the cost to install a bathtub in 2025 involves many variables from the type of tub to labor, plumbing, and finishing costs. In this guide, we’ll break down every aspect of the installation process, giving you a comprehensive idea of what to expect and how much to budget.

Average Cost to Install a Bathtub

The average cost to install a bathtub in the U.S. ranges between $1,400 and $10,000, depending on several factors. A standard alcove tub with basic installation might cost as low as $1,200 to $2,500, while high-end installations involving freestanding tubs, luxury materials, or custom tile work can exceed $7,000 or more.

Type of BathtubAverage Installation Cost
Alcove Tub$1,200 – $2,500
Drop-in Tub$2,000 – $5,000
Freestanding Tub$2,500 – $6,500
Whirlpool/Jetted Tub$3,000 – $8,000
Walk-in Tub$4,000 – $10,000+

Factors That Affect Bathtub Installation Costs

1. Type of Bathtub

The type of bathtub is the most significant cost factor. Some bathtubs require complex plumbing or reinforcement for additional weight.

Alcove tubs are budget-friendly and easy to install.

Drop-in tubs need a built platform, adding labor and material costs.

Freestanding tubs require specialized floor plumbing and may need structural support.

Jetted tubs need electrical wiring, increasing overall installation complexity.

Walk-in tubs, often installed for accessibility, are the most expensive due to specialized features and modifications.

2. Material of the Tub

Different materials not only affect the tub’s appearance but also installation and maintenance costs.

Acrylic: Lightweight, easy to install, and affordable ($500–$1,200).

Fiberglass: Budget-friendly but less durable ($300–$800).

Cast Iron: Extremely durable, retains heat well, but very heavy ($1,000–$3,500).

Porcelain on Steel: Durable and mid-range ($300–$1,500).

Copper or Stone: Luxury materials priced from $5,000–$10,000+.

3. Labor Costs

Labor makes up a substantial portion of the overall cost. On average, labor ranges from $500 to $2,000, depending on complexity.

Basic replacement: $500–$1,200

New installation (with plumbing and framing): $1,500–$3,000

Demolition of old tub and wall repairs: $200–$1,000 additional

4. Plumbing Modifications

If you are replacing an old tub with a new one of the same size and position, plumbing costs are minimal. However, moving plumbing lines can cost between $1,000 and $2,500, especially in homes with outdated systems or poor access.

5. Electrical Work (For Jetted or Walk-In Tubs)

Installing whirlpool or walk-in tubs requires electrical connections for pumps and heaters, which can add another $300–$1,000 in electrician fees.

Hidden or Additional Costs

When budgeting for bathtub installation, don’t overlook these often hidden costs:

Bathroom Floor Reinforcement

Heavy tubs like cast iron or stone may need joist reinforcement, especially on upper floors, costing between $500 and $1,500.

Water Heater Upgrade

A larger tub (like a soaking or jetted tub) may require more hot water than your current water heater can supply. Upgrading to a larger heater may cost $800–$2,500.

Tile, Waterproofing, and Wall Repair

Installing new tile or repairing drywall after removing an old tub can range from $500 to $2,000, depending on materials and extent of work.

DIY vs. Professional Installation

While a skilled DIYer can install a simple alcove tub for around $600–$1,200, we highly recommend hiring a professional for anything more complex. Mistakes in waterproofing, plumbing, or leveling can result in leaks, water damage, and costly repairs.

Professional installation offers:

Warranty on labor

Correct permitting

Code compliance

Proper sealing and waterproofing

Cost Breakdown by Installation Type

Replacing an Existing Bathtub

If you're swapping out an old tub for a similar model, costs are relatively low. Expect:

Removal of old tub: $200–$500

New tub installation: $1,000–$2,000

Total average: $1,500–$3,000

New Tub in a Bathroom Without One

This involves more extensive plumbing, framing, and possibly structural work.

Framing and drywall: $500–$1,000

Plumbing and drain install: $1,000–$2,000

Total average: $3,000–$6,000

High-End Remodel with Freestanding Tub

Luxury upgrades with custom finishes can range from $5,000 to $10,000+, especially with designer tubs, marble tile, and high-end fixtures.

Tips to Save Money on Bathtub Installation

Keep the same layout to avoid expensive plumbing modifications.

Choose a cost-effective material like acrylic or fiberglass.

Buy during sales or clearance events from home improvement stores.

Get multiple quotes from licensed professionals.

Bundle with a bathroom remodel to save on labor.

When Should You Replace Your Bathtub?

Consider replacing your bathtub if you notice:

Cracks or leaks

Stains or rust that can’t be removed

Outdated style or color

Mold issues behind walls or under tub

Discomfort or accessibility issues

Modern tubs offer better comfort, efficiency, and safety features, making them a wise investment for any home.

Conclusion

In 2025, installing a bathtub costs between $1,400 and $10,000, depending on type, material, labor, and additional requirements. For a basic alcove replacement, expect to pay around $2,000, while luxury freestanding or jetted tubs with custom finishes can exceed $8,000. Always request detailed quotes, check reviews, and hire licensed contractors to ensure a smooth, code-compliant installation.
