Single vs. Double Bathroom Vanities: Which to Choose | Alliance Millwork


Deciding Between Single And Double Bathroom Vanities

Are you renovating your bathroom or planning a new construction project? One of the key decisions you’ll need to make is whether to go for a single sink or a double sink vanity. The choice you make can significantly impact the functionality and aesthetics of your bathroom. In this article, we will explore the differences between single and double bathroom vanities and provide you with the information you need to make an informed decision.

Understanding the Difference: Single Sink vs. Double Sink Vanities

What is a Single Sink Vanity?

A single sink vanity, as the name suggests, features a single sink basin. It is designed to accommodate one person at a time and is ideal for smaller bathrooms or powder rooms. Single sink vanities come in various sizes, styles, and configurations, offering flexibility to suit different bathroom layouts.

What is a Double Sink Vanity?

On the other hand, a double sink vanity comes with two sink basins, allowing two people to use the bathroom simultaneously. This type of vanity is more spacious and offers added convenience, especially in households with multiple occupants or in master bathrooms where extra space is available.

Pros and Cons of Single Sink Vanities


Single sink vanities have their own set of advantages. Firstly, they are typically more affordable compared to double sink vanities. They also take up less space, making them an excellent choice for compact bathrooms. Single sink vanities can be more versatile in terms of design options, allowing you to focus on other aspects of bathroom decor.


However, single sink vanities may have limitations. If you have a larger family or frequently entertain guests, a single sink vanity might lead to congestion during busy mornings or evenings. Storage space can also be limited in some single sink vanity models, so you need to carefully consider your storage needs.

Pros and Cons of Double Sink Vanities


Double sink vanities offer several advantages that make them popular among homeowners. The primary benefit is the convenience of having two sinks, allowing two individuals to get ready simultaneously without any hassle. They provide ample countertop space and storage, making it easier to keep the bathroom organized and clutter-free.


While double sink vanities have their perks, they also have a few drawbacks. One of the main considerations is the cost. Double sink vanities are generally more expensive due to the additional plumbing and materials required. Another factor to keep in mind is the size requirement. Double sink vanities typically need a larger bathroom to accommodate them properly.

Factors to Consider when Choosing a Vanity for the Bathroom

When deciding between a single sink and a double sink vanity, several factors should be taken into account:

Size of the Bathroom

The available space in your bathroom is a crucial factor in determining whether a single or double sink vanity is suitable. Measure the dimensions of your bathroom and ensure that the chosen vanity will fit comfortably without making the space feel cramped.

Usage and Lifestyle

Consider how your bathroom is used on a daily basis. If you have a large family or share the bathroom with multiple people, a double sink vanity might be a practical choice. However, if you have a smaller household or limited space, a single sink vanity can still fulfill your needs.

Storage Needs

Evaluate your storage requirements. If you have many toiletries, towels, or other bathroom essentials to store, a double sink vanity’s additional storage space may be beneficial. However, if you have alternative storage solutions or a minimalist lifestyle, a single sink vanity might suffice.

Plumbing Considerations

Installing a double sink vanity requires additional plumbing work. Ensure that your bathroom’s plumbing infrastructure can support two sinks before making a decision. Consulting with a professional plumber can help determine the feasibility of installing a double sink vanity in your bathroom.

Design and Style Options

Both single and double sink vanities come in a wide range of designs, styles, and materials. Consider the overall aesthetic you want to achieve in your bathroom and choose a vanity that complements your desired design theme.

Cost Comparison

As mentioned earlier, cost can be a significant factor when deciding between single and double sink vanities. Double sink vanities are generally more expensive due to the added materials and plumbing requirements. Consider your budget and weigh it against your needs and preferences.

Maintenance and Cleaning

Maintenance and cleaning requirements should also be taken into consideration. Double sink vanities might require more effort and time to clean since there are two sink basins and a larger countertop area. Evaluate your willingness to commit to regular cleaning and maintenance before choosing a vanity.

Installation Process

The installation process can vary depending on whether you choose a single or double sink vanity. Double sink vanities usually require more complex plumbing work and may involve hiring professionals for proper installation. Single sink vanities are relatively easier to install, making them a more straightforward DIY project.


Choosing between a double sink vs single sink vanity depends on your individual needs, space availability, and budget. Consider the pros and cons, assess your bathroom’s requirements, and select a vanity that best suits your lifestyle and preferences. A well-chosen vanity can enhance the functionality and aesthetics of your bathroom, adding value to your home.
