Double Sink Bathroom Remodel: Should You Add One?

Explore the Benefits, Drawbacks, and Design Tips for Double Vanities

When planning a bathroom renovation, one of the most common design dilemmas is whether to include a double vanity. A double sink bathroom remodel can offer practical benefits, aesthetic upgrades, and even increase your home’s resale value—but it’s not the right fit for every layout or lifestyle.

In this blog, we’ll break down the advantages and disadvantages of double sink setups, explore space and plumbing requirements, and offer design tips to help you decide if a double vanity is worth including in your remodel.

What Is a Double Sink Bathroom Remodel?

A double sink bathroom remodel refers to updating your bathroom layout to include two sinks within a shared vanity area. These can either be part of a continuous countertop or separated into individual vanities, depending on space and design preference.

This feature is especially popular in primary bathrooms shared by couples or family members who require simultaneous use during peak hours.

Advantages of Adding a Double Sink

Convenience for Couples or Families

With two sinks, two people can get ready at the same time without battling over space. This streamlines morning and bedtime routines and reduces tension in shared bathrooms.

Increased Counter Space and Storage

A double vanity often spans a larger footprint, providing more surface area for toiletries and grooming tools. Many designs also include dual cabinets or drawers for personalized storage.

Enhanced Home Resale Value

Buyers often see a double sink bathroom remodel as a desirable upgrade. In competitive markets, it can be a small feature that helps your home stand out.

Improved Functionality

Two sinks mean two sets of plumbing fixtures, which can add flexibility. For instance, one person can brush their teeth while the other uses the sink for skincare or shaving without interference.

Balanced Design Symmetry

In terms of aesthetics, double vanities offer visual balance, especially when paired with matching mirrors, lighting, and cabinetry.

Potential Drawbacks of Double Sink Vanities

Requires More Space

A double vanity typically needs at least 60 inches of wall space. In small bathrooms, squeezing in two sinks can lead to cramped layouts and inefficient flow.

Higher Remodeling Costs

You’ll be paying for two sinks, two faucets, extra cabinetry, and often additional plumbing work. This increases material and labor costs compared to a single sink setup.

May Reduce Counter Space

Ironically, while a double vanity can offer more total countertop area, the division between the two sinks may reduce usable counter space per person compared to a larger single sink.

Not Always Necessary

In homes where the bathroom isn’t frequently shared, the second sink may go unused. In such cases, the extra space might be better allocated to a larger shower, linen closet, or makeup vanity.

When a Double Sink Bathroom Remodel Makes Sense

Consider a double sink bathroom remodel if:

• You and your partner have similar morning routines and need access at the same time.
• You’re upgrading a master bathroom and want to boost resale value.
• The layout of your bathroom can comfortably support a vanity that’s 60–72 inches wide.
• You want symmetrical aesthetics that pair well with dual mirrors and lighting.

Layout and Design Considerations

Measure the Space

Ensure there’s at least 6 feet of wall space available for a comfortable fit. Don’t forget to account for clearance between the vanity and other fixtures (like toilets, bathtubs, or doors).

Choose the Right Style

There are several types of double vanities to consider:

• Wall-mounted (floating) double vanities for modern, open designs
• Freestanding vanities with under-sink cabinetry for traditional spaces
• Split vanities for custom layouts with personal space for each user

Coordinate Fixtures and Finishes

Keep faucets, sinks, and drawer pulls consistent to maintain harmony. Use matching mirrors and overhead lighting for a cohesive look.

Add Power and Plumbing

Make sure to budget for dual power outlets and plumbing lines. Depending on your current setup, this could increase remodeling complexity and cost.

Design Ideas for Double Sink Bathroom Remodels

• Backlit Mirrors: Add drama and function with LED-backlit mirrors for each sink.
• Integrated Storage Towers: Place a tall cabinet between sinks for vertical storage.
• Undermount Sinks with Quartz Counters: Sleek and durable for long-term use.
• Matte Black or Brushed Brass Fixtures: Popular finishes that add contemporary flair.
• Floating Vanities with Undercabinet Lighting: Create a spa-like ambiance while keeping the space airy.

Should You Choose a Double Sink Bathroom Remodel?

A double sink bathroom remodel can be a smart, stylish upgrade—especially for households where shared bathroom time causes daily bottlenecks. While it does come with added costs and space requirements, the functional benefits, added storage, and visual appeal often make it a worthwhile investment. If your layout supports it and your lifestyle calls for it, a double vanity can transform your bathroom into a more efficient and luxurious space.
