Undermount vs. Drop-In Tub: Choosing the Right Bathtub for Your Bathroom


When it comes to selecting a bathtub for your bathroom, you have various options to consider. Two popular choices are undermount and drop-in tubs. Each type offers distinct features and aesthetics, catering to different design preferences and bathroom layouts. In this article, we will compare undermount and drop-in tubs, examining their differences, advantages, and considerations, to help you make an informed decision for your bathroom renovation or new construction.

1. Undermount Tub

An undermount tub is a bathtub that is installed beneath the bathroom’s surface, leaving the lip or rim of the tub hidden beneath the surrounding materials. This creates a sleek and seamless look, enhancing the overall aesthetics of the bathroom.

1.1 Aesthetics

One of the primary advantages of an undermount tub is its clean and modern appearance. By concealing the rim, the tub becomes a seamless part of the bathroom design, allowing other elements like tiles or stone to take center stage.

1.2 Space Efficiency

Undermount tubs are ideal for smaller bathrooms or spaces with limited floor area. Since they are installed below the surface, they take up less visual space, creating an illusion of more room in the bathroom.

1.3 Cleaning and Maintenance

The lack of exposed edges in an undermount tub makes cleaning and maintenance easier. There are no corners or edges where dirt and grime can accumulate, simplifying the cleaning process.

2. Drop-In Tub

A drop-in tub, also known as a platform or deck-mounted tub, is designed to “drop” into a platform or deck structure. The tub’s lip or rim rests on the deck, creating a visible edge around the tub.

2.1 Versatility in Design

Drop-in tubs offer more versatility in design. The surrounding deck can be constructed with various materials, such as tiles, stone, or wood, allowing for creative customization and the integration of design elements.

2.2 Accessibility

The visible lip of a drop-in tub makes it easier to step into and out of the bathtub. This accessibility can be beneficial for individuals with mobility concerns or those who prefer a bathtub with a more traditional design.

2.3 Replacement and Repairs

In the event of damage or the need for replacement, drop-in tubs can be easier to remove and replace since they are not built into the structure of the bathroom.

3. Considerations for Installation

3.1 Undermount Tub

  • Installation Complexity: Installing an undermount tub requires careful planning and professional installation. It may involve cutting into the bathroom surface to accommodate the tub.
  • Support Structure: Since the tub is placed below the surface, a sturdy support structure is necessary to hold the weight of the tub and water.

3.2 Drop-In Tub

  • Deck Design: The design and construction of the deck surrounding the drop-in tub need to be well-executed to ensure a seamless and aesthetically pleasing integration.
  • Waterproofing: Proper waterproofing is essential to prevent water damage to the deck and surrounding materials.


In conclusion, the choice between an undermount tub and a drop-in tub depends on your preferences, bathroom design, and available space.

Choose an undermount tub if you prefer a sleek, modern look, and have a smaller bathroom or limited floor space. Undermount tubs are easy to clean and create a visually open bathroom environment.

Opt for a drop-in tub if you desire more design flexibility and accessibility. Drop-in tubs offer a wide range of design possibilities with the surrounding deck and provide a more traditional bathtub experience.

Remember to consider your budget, bathroom layout, and overall design vision when selecting between an undermount tub and a drop-in tub. Both options can enhance the beauty and functionality of your bathroom, creating a relaxing and enjoyable bathing experience.
