Concrete Bathtubs: Weighing the Pros and Cons for Your Luxury Bathroom


When it comes to choosing a bathtub for your bathroom remodel or new construction project, the variety of materials available can be overwhelming. Concrete bathtubs have gained popularity in recent years for their unique aesthetic and durability. However, like any material, they come with their own set of advantages and disadvantages. 

In this blog post, we will delve into the pros and cons of concrete bathtubs, helping you make an informed decision for your next project.

What Are the Disadvantages of Concrete Bathtubs?

Porosity and Maintenance Requirements

One of the primary concerns with concrete bathtubs is their porous nature. Concrete is inherently porous, which means it can absorb water and moisture. This characteristic can lead to a host of issues, including the growth of mold and mildew. 

To combat this, concrete bathtubs require sealing with a penetrating sealer or a durable concrete coating. This sealant needs to be reapplied periodically to maintain its effectiveness, adding to the overall maintenance burden.

Additionally, the porous nature of concrete makes it susceptible to stains. Spills and splashes from bath products, soaps, and even hard water can leave unsightly marks on the surface of the tub. Cleaning a concrete bathtub can be more complicated than other materials, requiring special cleaners and techniques to avoid damaging the sealant.

Weight and Installation Challenges

Concrete bathtubs are significantly heavier than their counterparts made from materials like acrylic, fiberglass, or even some types of stone resin. On average, a concrete bathtub can weigh around 600 pounds or more. This immense weight makes them difficult to maneuver during installation and may require specialized equipment and additional labor costs.

Moreover, the structural integrity of the floor beneath the bathtub must be considered. The floor may need to be reinforced to support the weight of the concrete tub, especially in multi-story buildings. This additional reinforcement adds to the complexity and cost of the installation process.

What Are the Advantages of Concrete Bathtubs?

Excellent Heat Retention

One of the standout features of concrete bathtubs is their ability to retain heat. Concrete has high thermal mass, meaning it can absorb and store heat for extended periods. This property makes concrete bathtubs ideal for long, relaxing soaks, as the water will stay warm for a longer time compared to tubs made from materials with lower thermal mass.

Durability and Longevity

Concrete bathtubs are known for their sturdiness and long life expectancy. Once installed and properly maintained, a concrete bathtub can last for decades without showing significant signs of wear and tear. Their durability makes them a sound investment for homeowners looking for a long-term solution for their bathroom.

Aesthetic Versatility

In today’s market, concrete bathtubs are available in a wide variety of shapes, sizes, and colors. This versatility allows homeowners and designers to choose a tub that perfectly complements the overall aesthetic of the bathroom. Whether you prefer a sleek, modern look or a more rustic, natural appearance, there is a concrete bathtub design to suit your taste.

Concrete bathtubs can also be customized with various finishes and textures, adding to their visual appeal. From smooth, polished surfaces to more rugged, textured finishes, the design possibilities are nearly endless.

Comparing Concrete Bathtubs with Other Materials

Stone Resin Bathtubs

At T&L International, we specialize in stone resin bathtubs, which offer many of the benefits of concrete without the associated drawbacks. Our proprietary InspireStone® stone resin material is designed to mimic the look and feel of natural stone while being significantly lighter and easier to maintain.

Stone resin bathtubs are non-porous, which means they do not absorb water or moisture, eliminating the risk of mold and mildew growth. They are also resistant to stains and do not require periodic sealing like concrete. The lightweight nature of stone resin makes installation easier and less costly, without the need for floor reinforcement.

In terms of aesthetics, stone resin bathtubs are available in a wide range of shapes, sizes, and finishes. They offer the same design versatility as concrete tubs, allowing you to create a luxurious and personalized bathroom space.

Acrylic Bathtubs

Acrylic bathtubs are another popular alternative to concrete. They are lightweight, easy to install, and come in a variety of shapes and sizes. Acrylic is non-porous, making it resistant to stains and easy to clean. However, acrylic bathtubs do not retain heat as well as concrete or stone resin, which can be a drawback for those who enjoy long soaks.

While acrylic bathtubs are generally more affordable than concrete or stone resin, they may not offer the same level of durability. Over time, acrylic can scratch and fade, and it may require more frequent replacement compared to sturdier materials.

When it comes to choosing the right bathtub for your bathroom, it’s essential to consider both the advantages and disadvantages of different materials. Concrete bathtubs offer excellent heat retention, durability, and aesthetic versatility, but they also come with challenges such as porosity, maintenance requirements, and significant weight.

For those looking for a luxurious and low-maintenance alternative, our stone resin bathtubs at T&L International provide the perfect solution. With the look and feel of natural stone without the drawbacks, our bathtubs offer long-lasting beauty and comfort for any bathroom design.
