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

Bathtub Replacement Cost Factors

Removal

Removing an old tub costs between $200 and $1,200. Standard alcove and freestanding tubs generally only cost $200 to $300 for removal and disposal. However, oversized tubs, cast-iron models, unusual configurations, and in-deck and sunken tubs can cost up to $1,200to remove because they're more challenging and time-consuming. If you’re replacing your old bathtub, then be sure to budget for the cost of removing your preexisting tub.

Floor Modification and Reinforcement

Floor reinforcement costs $300 to $800, equating to $100 to $300 per joist, plus framing. For heavy tubs, like granite, marble, or cast iron, the standard bathroom floor may not be strong enough to hold the weight over time. You’ll also need to factor in about 40 to 60 gallons of water and the weight of the occupant while the bath is in use. In these cases, the floor needs reinforcement to spread and safely hold the tub's weight. 

Surround

The total cost for a new bath surround is $3,120 to $9,000. This includes framing the walls, framing the plumbing, preparing the walls with a water-resistant backer board, and installing the surround. 

How much you'll spend depends heavily on the surrounding material you choose. Acrylic, fiberglass, and composite surrounds give a clean, practical look and are all budget-friendly. Surrounds made of tile, quartz, and natural stone—like marble or granite—give the space a luxurious, spa-like feel, but they'll cost considerably more.

The table below shows you the typical costs for different surround materials and assumes a typical bathtub surround size of 60 square feet.

Faucets

Installing a new bathtub faucet costs between $100 and $700. Bathtub faucets are often more costly than sink faucets because they have a higher gallons-per-minute capacity to fill your bathtub as quickly as possible. There are three main types: deck-mounted are the most budget-friendly, wall-mounted are mid-range, and floor-mounted are the most costly. 

Plumbing Upgrades

Switching a tub like-for-like requires minimal plumbing work, assuming the existing plumbing is in good repair. However, plumbing costs can quickly rocket if you're switching an alcove bath for a cast-iron, freestanding tub, or jetted tub. Labor costs rise rapidly in any installation where the existing plumbing configuration needs changing. Plumbers charge $45 to $200 per hour, and adding new plumbing is a laborious job. Your plumber will have to frame the new plumbing inside the walls or floors and seal off or remove any old plumbing. 

Labor

Labor costs for installing a new tub generally runs between $100 and $2,000 per project. This covers a simple like-for-like bathtub replacement at the low end—with no remedial work or surround installation—and more complex installations on the high end, including floor reinforcement and moving existing plumbing.

Permits

The typical cost for a plumbing permit is between $50 and $500, depending on your location and the scope of the job. Depending on where you live and exactly what you're planning to do, you may not need a permit, but it's worth checking with your local planning office, nevertheless.

Shower to Tub Conversion

It typically costs between $4,000 and $6,000 to convert a shower to a tub. However, depending on the amount of work involved and the size of the area, you could pay as little as $1,900 for a compact, simple conversion. But a more challenging or more elaborate conversion could cost as much as $10,400. Plus, if you need to reconfigure or change the size of the space, you'll be looking at the price of a bathroom remodel—or at least a partial remodel, which could cost you up to $15,000.

Additional Factors

Bathtub installation may require additional services, such as:

• Cost to replace a water heater: $800–$1,600

• Cost to install a bath liner: $2,100–$7,700

• Cost to upgrade an electrical panel: $500–$1,800

For example, if you double the size of your tub, you may need a bigger water heater or a new electrical panel to handle the jets.

Bathtub Sizes, Styles, Prices, and Installation Costs

Bathtub installations cost between $600 and $14,000, and one of the biggest determining factors is the type of tub you choose. Other factors that influence the job’s complexity may include whether new plumbing is necessary or reinforcing your flooring. Additionally, the kind of tub determines if any construction or remodel work is required.

Jet & Whirlpool Tub Costs

The total cost to install a jetted whirlpool bathtub ranges between $1,500 and $17,000 with an average price of $6,500. This price includes the cost of the tub, installation, and materials. You’ll find that the price varies with the shape, size, and brand. 

Labor typically costs $450 to $2,000, not including extra work like hanging new walls or pouring a concrete slab. The project takes an average of 18 hours to complete, with a total range of six to 25 hours.

Average Jet Tub Installation Costs

*Not all installations require joists and a concrete slab.

Installation requirements of a standard jetted bathtub include materials like:

• Joists to strengthen the floor

• Glue and sealant

• Concrete to create an even surface

• Wires and parts to connect to the home's electrical system

Not all installations need joists and a concrete slab, but almost all require glue, sealant, and hookups to electrical systems. A full-bathroom remodel may be required to handle the extra weight of the tub. Your pro will also have to seal the area surrounding the tub to prevent leaks. 

When seeking to install a jetted indoor or outdoor tub, it’s best to start with hiring a plumber. You’ll need to hire a plumber and a bathroom remodeler in most cases. A standard contractor is unlikely to have experience in all of these areas.

Cost to Install Jetted Bathtub vs. Whirlpool Hot Tub

The average cost of installing a jetted bathtub falls between $1,500 and $17,000, while hot tub installation costs $1,250 and $10,700. The primary difference is the cost of the tubs themselves, although hot tubs cost less to install.

*This chart doesn't include the cost of joists, a concrete slab, or any remodeling costs that may be necessary when installing either type of tub.

Clawfoot Tub Cost

Clawfoot tubs cost $600 to $10,000, averaging about $2,000. The most expensive options feature high-end materials like copper or natural stone.

Clawfoot tubs range from a classic 19th-century style to a modern look with clean lines. This makes them a great fit for almost any bathroom design, from vintage to minimalist.

Soaking Tub Cost

The average price of a soaking tub is $1,000, with a range of $600 to $13,000. The cost depends mostly on the size since this type of tub is often large enough for two.

Soaking tubs can be drop-in or freestanding. The basin is usually at least 14 inches tall to allow for soaking. 

Cost of a Freestanding Tub

The cost of a freestanding tub is $750 to $12,000, averaging around $2,500. This style allows for free movement on all sides and usually requires a larger bathroom.

Garden tub prices range from $900 to $5,000. This type is freestanding and tends to be larger than average.

Walk-In Tubs

Walk-in tubs range from $2,000 to $8,000, or $5,000 on average. The price point depends mostly on the features, like jets.

Walk-in styles mainly accommodate people with mobility issues and are an excellent choice for those who would like to upgrade their bathroom for aging in place. They’ve got all the features you expect from a high-end option, like whirlpool jets or built-in alcoves for soap.

New Tub Costs by Material

The bathtub material you choose influences how much you'll pay for the tub and how much you'll pay for labor, construction, remodeling, and plumbing. The least expensive option is to switch like-for-like, as this involves the least amount of work. However, in terms of tub cost and installation prices, steel and fiberglass are among the most budget-friendly options, while ceramic tile and granite are among the most costly.  

Steel, enameled cast iron, and solid surface all have a modern, usually white, appearance. A granite bathtub or soaking tub is a great option for homeowners who want a real wow factor in their bathroom. Granite or natural stone tubs have highly polished, sealed interiors, while the exteriors can be rough, rustic, and natural or smooth and contemporary. Every tub is unique because the material is natural. 

Tile is another great option for creating a stunning focal point with your bathtub. Small, ceramic or glass mosaic tiles cover tile baths. You can have intricate, custom designs worked into the tile layout. It’s costly but effective, and you can choose a modern design or something that echoes the famous bathhouses of ancient Rome.

DIY Tub Installation vs. Hire a Pro

Installing or replacing a bathtub really isn't a DIY project, unless you’re a qualified plumber. A lot can go wrong with bathtub installation if you don't have professional training, so this is definitely a job for a local bathroom remodeler. 

Hiring a plumber in your area ensures you get long-lasting professional results. Plus, they'll help you take care of any permitting and code requirements.

Bathtub installation requires plumbing, soldering, general construction, and carpentry skills and potentially calls for electrical skills, depending on the tub. Seemingly minor mistakes, such as not leveling correctly or getting a tight seal on drainage pipes can cause significant and costly damage to your property.
