Single vs Double Vanities in Your Bathroom: Pros and Cons

Single vs Double Vanities in Your Bathroom Single vs Double Vanities in Your Bathroom: Pros and Cons

When designing or remodeling a bathroom, one of the decisions you’ll need to make is whether to install a single or double vanity. Both options have their pros and cons, depending on your needs, space, and budget.

Single Vanity

A single vanity is a type of bathroom fixture that includes one sink and its associated plumbing. It typically comes with a cabinet underneath for storage, and may also include a mirror above the sink. Single vanities are often used in smaller bathrooms or in situations where only one person will be using the bathroom at a time. They are a popular choice due to their compact size, cost-effectiveness, and simplicity in design and maintenance.


  1. Space-Saving: Single vanities take up less room, making them ideal for smaller bathrooms.
  2. Cost-Effective: They are generally less expensive than double vanities, both in terms of the unit cost and installation.
  3. Simplicity: With only one sink to clean and maintain, they can be easier to manage.


  1. Limited Use: Only one person can use the sink at a time, which might not be ideal for shared bathrooms.
  2. Less Storage: Single vanities usually offer less storage space compared to double vanities.

Double Vanity

A double vanity is a bathroom fixture that includes two sinks, each with its own set of plumbing. It usually features a larger countertop and cabinet space underneath for storage. Above the sinks, there may be one large mirror or two smaller ones. Double vanities are commonly found in master bathrooms or shared bathrooms, allowing two people to use the sinks simultaneously. They offer more storage space and convenience, but they also require more room and can be more expensive than single vanities.


  1. Convenience: Double vanities allow two people to use the sinks simultaneously, making morning routines more efficient in shared bathrooms.
  2. Increased Storage: They typically provide more storage space, which can be beneficial in a busy household.
  3. Adds Value: Having a double vanity can increase the value of your home, as it’s often seen as a luxury feature.


  1. Takes More Space: Double vanities require more space, which might not be feasible in smaller bathrooms.
  2. Higher Cost: They are generally more expensive to purchase and install than single vanities.
  3. More Maintenance: With two sinks to clean and potentially repair, maintenance can be more demanding.

The choice between a single and double vanity depends on your specific needs and circumstances. If space and budget are limited, a single vanity could be the best option. However, for larger bathrooms shared by multiple people, a double vanity could provide the convenience and storage needed.

Upgrading from Single to Double Vanity in the Bathroom: A Guide

Upgrading from a single to a double vanity in your bathroom can be a great way to add convenience and value to your home. However, it’s a significant project that requires careful planning. Here are some steps to consider:

  1. Assess Your Space: The first step is to measure your bathroom to ensure there’s enough space for a double vanity. Double vanities require more room than single ones, so make sure you have ample space not only for the vanity itself but also for comfortable movement around it.
  2. Plan Your Plumbing: Upgrading to a double vanity means you’ll need additional plumbing for the second sink. This might involve rerouting or extending your existing plumbing, which should be done by a professional plumber.
  3. Choose Your Vanity: There are many styles of double vanities available, from modern to traditional. Consider your storage needs, preferred style, and budget when choosing your new vanity.
  4. Installation: Installing a double vanity involves removing the old single vanity, installing the new one, and setting up the additional plumbing. It’s recommended to hire a professional for this job to ensure everything is installed correctly and safely.
  5. Finishing Touches: Once your new double vanity is installed, you can add the finishing touches. This might include installing new mirrors above each sink, adding lighting fixtures, or updating your faucets and hardware.

Double vanity bathroom remodeling can significantly improve the functionality of your bathroom, especially if it’s shared by multiple people. While it’s a substantial project that involves time and investment, the added convenience and potential increase in home value can make it worthwhile.
