How Much Does It Cost to Replace or Install a Bathtub?

The tub is often the focal point in a bathroom, and it's especially important if you enjoy soaking at the end of a long, stressful day. Whether you prefer the look of a modern freestanding tub or the nostalgic appearance of a claw-foot bath, the right tub can set the tone for the entire space. If your current tub is cracked, stained or outdated, you may be wondering whether it’s worth fixing or time to pull the trigger on a new tub installation.

Before diving into a renovation, it helps to understand the true cost to replace a bathtub. This guide breaks down everything you need to know about bathtub replacement and installation costs and whether you might save money by making repairs instead.

Should You Repair or Replace a Bathtub?

Plumbing fixtures such as bathtubs tend to have long useful lifespans, so you may not need to replace yours unless you want to update the aesthetic or there's a serious issue. The lifespan of a bathtub typically depends on the material. Acrylic tubs last between 10 and 15 years, while porcelain-enameled cast-iron tubs can last several decades with proper care. Here's how to judge if a repair will solve your problem or a replacement is the smarter move:

• Repairing the tub can address cosmetic and other minor issues, such as surface scratches, small chips in the enamel or a leaking faucet. Bigger problems, such as deep cracks, rust, persistent mold or outdated plumbing, can signal it's time for replacement.

• Replacing the fixture might be the smart option if you're remodeling the entire bathroom in an older home or you want to update the room’s aesthetic with a new walk-in shower or freestanding soaking tub.

Changing out the bathtub can allow you to redesign the entire bathroom exactly to your liking and add insulation to boost energy efficiency.

What Are Some Signs It's Time to Replace a Bathtub?

Replacing a bathtub is a potentially expensive choice. However, if your tub needs to be replaced, ignoring the problem could lead to costly damage to your home, as well as higher utility bills. The following signs indicate you should start shopping for a new bathtub.

• Cracks and chips. Deep cracks and chips in the surface of your bathtub can cause the fixture to fail.

• Rust and corrosion. Accumulated rust can make your bathtub look bad and may also be dangerous. Rust develops as a reaction to oxygen in the air when iron or steel is exposed to moisture. This corrosion can weaken the metal in your tub and expose you to high levels of lead. You might use a rust remover to get rid of visible signs of corrosion, but that won't address the underlying issue.

• Recurring mold or mildew. Frequent battles to remove mold and mildew may indicate it's time to replace the tub. In a moist environment, mold and mildew can spread quickly and may pose a health hazard to sensitive individuals.

• Outdated design. An older fixture may take up too much space and not match your current décor.

• Difficulty cleaning. Porous materials such as tub enamel can trap oil and grime, making it difficult to clean.

• Water leaks or water damage. Leaks or evidence of water damage around your bathtub can be a sign of a failed seal or structural issue and signal it's time for a new tub installation.

• Damage to surrounding wall tile. The need to replace crumbling or visibly damaged wall tile is an opportunity to upgrade the bathtub.

How Much Does Bathtub Replacement Cost on Average?

The average cost to replace a bathtub ranges from $1,500 to $8,000 (CAD 2,104 to CAD 11,221). This typically includes the cost of required permits, removal and disposal of the old tub, installation of the new one, any needed plumbing adjustments and repairing the surrounding walls or floor. The type of tub you choose can affect the total cost:

• Standard alcove tubs cost between $1,500 and $2,000 (CAD 2,104 and CAD 2,805).

• Bathtub and shower combinations cost between $2,000 and $4,500 (CAD 2,104 and CAD 6,312).

• Jetted tubs cost between $3,000 and $8,000 (CAD 4,208 and CAD 11,221).

If you're replacing your existing tub with a different style or size, there may be additional plumbing, electrical and framing/finishing costs.

What Are the Cost Factors for a New Tub Installation?

Various cost factors can affect the amount you pay to install a new bathtub, including the type of tub you choose, modifications to the plumbing, removal and disposal of the old tub, tile installation, labor charges and permit fees.

Type of Bathtub

The design and type of material you choose for your new tub play an important role in installation costs. A drop-in tub is the most affordable choice, typically costing between $1,800 and $3,500 (CAD 2,525 and CAD 4,909). Custom tubs made from stone or copper are the most expensive option, costing between $4,000 and $13,000 (CAD 5,610 and CAD 18,233). Different materials and their costs include:

• Acrylic or fiberglass. Tubs made from these materials are the least expensive option. Affordable and lightweight, these tubs cost between $300 and $1,200 (CAD 421 and CAD 1,683).

• Cast iron. More durable than acrylic, cast iron tubs resist chips, dents and scratches, but they're heavier and harder to install. They cost $600 to $3,000 (CAD 842 to CAD 4,208).

• Enameled steel. These tubs can be prone to chipping, but they're relatively budget-friendly, with costs between $300 and $1,500 (CAD 421 and CAD 2,102).

• Solid-surface or stone. Solid-surface and stone tubs are stylish and luxurious and a popular choice for high-end homes. The cost varies depending on the exact material and design, but average prices range from $2,000 to $10,000 (CAD 2,805 to CAD 14,026).

Plumbing Modifications

Moving your tub to a different spot in the bathroom requires changes to the plumbing. These modifications can cost between $200 and $700 (CAD 281 and CAD 982), depending on plumbing rates where you live and how much work needs to be done.

Old Tub Removal and Disposal

Not only do you have to pay for the removal of the old tub, you also have to pay for its disposal. On average, tub disposal costs between $150 and $750 (CAD 210 and CAD 1,052).

Tile Installation

If your new bathtub will be tucked into an alcove and surrounded by tiled walls, you may pay more for labor costs because tiling is detailed, skilled work.

Labor Charges

Licensed plumbers charge between $45 and $150 per hour (CAD 63 and CAD 210). Some may also charge a flat rate to come out and inspect the job before they do any work. You can expect to pay a higher rate for a more experienced plumber, but the extra cost can help ensure the job is done correctly. Plumbing for new tub installations costs between $800 and $4,600 (CAD 1,122 and CAD 6,452).

Permits and Inspections

Check with your local building and planning department before you get started. Most bathtub remodeling projects require permits, which cost between $50 and $250 (CAD 70 and CAD 351).
