Replacing a bathtub is a major bathroom upgrade that can enhance comfort, increase your home’s value, and improve daily life. But how much does it really cost to replace a bathtub in 2025?
En esta guía completa, we break down everything you need to know—from average costs and pricing by tub type and material, to hidden expenses and smart money-saving tips. Whether you’re a homeowner planning a remodel or a contractor advising clients, this article will give you clear insights into what to expect.
What Is the Average Cost to Replace a Bathtub in 2025?
The average cost to replace a bathtub in 2025 ranges between $1,400 y $6,500, depending on several key factors such as bathtub type, material, labor, and plumbing complexity.
Here’s a general breakdown:
| Project Type | Estimated Cost |
| Basic tub replacement (same size/type, no major changes) | $1,400 – $2,800 |
| Mid-range remodel (upgraded tub and minor plumbing changes) | $2,800 – $4,800 |
| Full renovation with premium/custom bathtub | $4,800 – $6,500+ |
Labor typically accounts for 50% or more of the total cost, especially if structural changes or retiling are needed. Luxury tubs with advanced features such as whirlpool jets or solid-surface materials can significantly raise the budget.
Key Factors That Influence Bathtub Replacement Costs
Several components influence the final price tag of your bathtub replacement:
Type of Bathtub: Different tub styles come with different price tags. Freestanding tubs are often more expensive to install than alcove models due to plumbing and space considerations.
Material of the Tub: Acrylic tubs are affordable and lightweight, whereas cast iron tubs are heavy and costly to install due to structural reinforcement needs.
Labor and Installation: Are you replacing the tub in an existing footprint or moving the plumbing lines? Labor costs can vary widely depending on complexity and local rates.
Bathroom Layout: Older homes might require floor reinforcement, plumbing rerouting, or even wall reconstruction to accommodate a new bathtub style or size.
Removal and Disposal: Demolishing the old tub and properly disposing of the materials can add $200–$600 to the bill.
Additional Features: Jets, heated bases, chromotherapy lighting, or digital controls will significantly increase the total cost.
Bathtub Replacement Cost by Bathtub Type
When choosing a new bañera, the style you select will significantly influence the total replacement cost. Here’s a quick overview of average costs for popular bathtub types in 2025:
| Bathtub Type | Average Cost (Tub + Instalación) | Typical Size (pulgadas) | Ideal For |
| Alcove | $1,400 – $2,800 | 60 x 30 | Standard bathrooms |
| Freestanding | $2,500 – $5,000 | 55–72 x 28–34 | Moderno / luxury aesthetics |
| Drop-in | $2,000 – $4,000 | Varies | Custom platforms or surrounds |
| Walk-in | $3,500 – $7,000+ | 52–60 x 28–32 | Seniors / mobility access |
| Esquina | $2,200 – $4,500 | 60 x 60 (typical) | Large bathrooms or spa setups |
| Whirlpool/Air Jet | $3,000 – $6,500+ | 60–72 x 32–36 | Spa-like luxury installations |
Alcove Bathtub
An alcove bathtub is the most common and affordable option, installed between three walls and typically paired with a shower. Standard sizes are 60 x 30 pulgadas, and designs prioritize space efficiency. Ideal for small to mid-size bathrooms, alcove tubs are easy to replace and cost-effective to install. Most models come in acrylic or porcelain over steel, and you can upgrade with tile surrounds or built-in shelving.
Freestanding Bathtub
Freestanding tubs are visually striking and ideal for open bathroom layouts. Ranging from 55 a 72 inches in length, these tubs come in sculptural shapes like oval, slipper, and clawfoot. Materials vary from acrylic to cast iron or solid surface stone. While beautiful, they often require floor reinforcement and plumbing adjustments, making installation more complex and expensive.
Drop-in Bathtub
Drop-in tubs are installed inside a custom-built platform or deck, offering a seamless, integrated look. Common in larger bathrooms, these tubs can vary in size and shape, depending on the platform design. They’re often used in upscale remodels where homeowners want full control over the surrounding tile, cabinetry, or ledges. Installation costs are higher due to the framing and finishing required.
Walk-in Bathtub
Designed for safety and accessibility, walk-in tubs feature a side door, built-in seat, grab bars, and anti-slip surfaces. Typical sizes are 52–60 inches long and 28–32 inches wide, with deeper soaking depth. Ideal for seniors or people with mobility concerns, these tubs often require specialized installation and may include hydrotherapy or air jets. Some models also need electrical connections for heating and drainage systems.
Corner Bathtub
Corner bathtubs are triangular or fan-shaped, designed to fit into a bathroom corner. Average dimensions are 60 x 60 pulgadas, making them larger and more luxurious than standard tubs. They’re often used in master bathrooms or spa-like layouts. While corner tubs offer aesthetic appeal and soaking comfort, their size and plumbing configuration lead to higher installation costs.
Whirlpool and Air Jet Bathtub
These high-end tubs come with built-in water or air jets that offer therapeutic massage effects. Available in both alcove and freestanding styles, their sizes range from 60 a 72 inches in length. Whirlpool tubs use powerful water jets, while air tubs provide gentle bubbling. These tubs require electrical hookups, reinforced subfloors, and advanced plumbing, which drives up both tub and installation costs.
Bathtub Replacement Cost by Bathtub Material
The material you choose for your bathtub significantly affects not only the upfront cost but also installation complexity, durabilidad, mantenimiento, and heat retention. Here’s a quick comparison of the most common bathtub materials and their average replacement costs in 2025:
| Material | Average Cost (Tub + Instalación) | Durabilidad | Retención de calor | Peso |
| Acrílico | $1,400 – $2,800 | Moderado | Good | Light |
| Fibra de vidrio | $1,200 – $2,400 | Bajo | Moderado | Very light |
| Porcelain-Enameled Steel | $1,500 – $2,800 | Good | Fair | Medium |
| Hierro fundido | $3,000 – $5,500 | Excellent | Excellent | Muy pesado |
| Solid Surface / Stone Resin | $3,500 – $6,000 | Excellent | Very good | Pesado |
| Copper | $4,500 – $7,500+ | Excellent | Excellent | Medium–heavy |
Acrylic Bathtub
Acrylic tubs are lightweight, asequible, and available in various shapes and colors. They retain heat well and resist mildew, but can scratch easily over time. Their ease of installation makes them a top choice for residential remodels.
Fiberglass Bathtub
Fiberglass is the most budget-friendly material, making it ideal for quick renovations or rentals. While it’s easy to install and repair, it’s prone to scratching, fading, and cracking with frequent use over time.
Porcelain-Enameled Steel Bathtub
These tubs offer a smooth, glossy finish at a mid-range price. They’re resistant to most stains and scratches, but can chip if struck. They’re heavier than fiberglass but easier to install than cast iron.
Bañera de hierro fundido
Cast iron tubs are extremely durable and luxurious, with unmatched heat retention. Their classic look and long lifespan justify the higher cost—but due to their weight, installation often requires floor reinforcement.
Solid Surface / Stone Resin Bathtub
Made from engineered stone or composite resin, these tubs provide a high-end, modern look with excellent insulation. They are heavy and more expensive but offer seamless, matte finishes and exceptional durability.
Copper Bathtub
Copper tubs are premium, artisan products that offer natural antimicrobial properties and a striking aesthetic. They retain heat well and last for decades, but come at a high price and require occasional polishing to maintain their patina.
Additional Expenses to Notidomi For During a Tub Remodel
Beyond the tub and installation, there are several costs you will overlook:
- Demolition and disposal: $200–$600
- Plumbing modifications: $400–$1,500
- Tile work or wall surrounds: $900–$2,500
- Waterproofing membranes: $150–$400
- New fixtures or fittings (grifos, drains): $150–$600
- Permits and inspections: Varies by location
How to Save Money on Bathtub Replacement?
Looking to keep costs under control? Here are smart strategies to reduce expenses:

- Time Your Remodel Strategically: Schedule your project during the off-season (late fall or winter) when contractors may offer lower rates and manufacturers promote discounts.
- Compare Multiple Contractor Quotes: Always get at least 2–3 quotes. Don’t just compare price—look at experience, warranty, and installation timeframes.
