If you have ever fought over bathroom counter space during the morning rush, you already understand the appeal of his and hers sinks. A double-sink bathroom gives each person their own sink, their own mirror space, and their own storage -- turning a daily bottleneck into a smooth routine.
But double sinks are not right for every bathroom. They cost more, require more space, and involve additional plumbing. This guide covers everything you need to decide whether his and hers sinks are the right choice for your bathroom remodel, including real costs from our projects across New Jersey and Pennsylvania.
What Are His and Hers Sinks?
His and hers sinks (also called double sinks, dual sinks, or a double-sink vanity) refers to a bathroom setup with two separate sinks, each with its own faucet and drain. The two sinks can be installed in a single long vanity, in two separate vanities placed side by side, or even on opposite walls of the bathroom.
The concept is simple: each person gets their own sink and surrounding counter space for daily use. No waiting, no reaching over each other, no fighting over who left toothpaste in the basin. His and hers sinks are most commonly found in master bathrooms but are also popular in shared family bathrooms and jack-and-jill configurations between bedrooms.
The name "his and hers" is traditional, but the setup works for anyone sharing a bathroom -- couples, roommates, siblings, or parents sharing a bathroom with a child. The benefit is personal space, regardless of who is using it.
Pros of His and Hers Sinks
There are several compelling reasons to install double sinks in your bathroom. Here are the advantages we hear most often from homeowners:
No More Morning Fights
This is the number one reason couples install his and hers sinks. When two people need to get ready at the same time -- brushing teeth, washing faces, applying makeup, shaving -- a single sink creates a bottleneck. Two sinks mean two people can get ready simultaneously without waiting or bumping elbows.
More Counter Space
A double-sink vanity is typically 60 to 72 inches wide, compared to 30 to 48 inches for a single-sink vanity. Even accounting for the second sink basin, you end up with significantly more total counter area. Each person can keep their daily-use items (soap, toothbrush, skincare products) at their own station without cluttering the other's space.
Personal Organization
Each person gets their own drawers, cabinet space, and counter area. One person can organize by category while the other tosses everything in a drawer -- and neither approach affects the other person. This separation reduces arguments about bathroom cleanliness and organization.
Increased Home Value
In the New Jersey housing market, buyers expect double sinks in master bathrooms. A home with a single-sink master bath can feel dated compared to competing listings. His and hers sinks are one of those features that buyers notice and value, making your home more attractive and competitive when it comes time to sell.
Better Hygiene
Separate sinks mean separate drains and separate basins. If one person is sick, the other can use a completely separate fixture. Each person can also maintain their preferred level of cleanliness without affecting their partner's experience.
Cons to Consider
Double sinks are not the right choice for every bathroom. Here are the trade-offs to weigh:
Higher Cost
Two sinks means two faucets, two drain assemblies, two sets of supply lines, and a larger vanity or two separate vanities. The vanity alone can cost 40-60% more than a single-sink equivalent. Plumbing labor doubles as well. For homeowners on a tight budget, that money might be better spent on premium finishes for a single sink setup. See our complete NJ bathroom remodel cost guide for detailed pricing.
Space Requirements
A double-sink vanity needs at least 48 inches of wall space (60-72 inches is standard). In small bathrooms, fitting two sinks can make the room feel cramped and leave insufficient counter space around each basin. If your bathroom is under 50 square feet, a single sink with more counter space may actually function better day to day.
Additional Plumbing
If your current bathroom has a single sink, adding a second requires running additional water supply lines and a new drain line. This is straightforward if the second sink is close to the first (same vanity or same wall), but more complex and expensive if you are placing sinks on separate walls. Plumbing modifications typically add $500 to $2,000 to the project.
Less Counter Space Per Sink
This might seem counterintuitive since the total counter area is larger, but each individual person gets less usable counter space than they would with a single wide vanity. A 60-inch double-sink vanity gives each person about 24 inches of usable counter space, whereas a 48-inch single-sink vanity gives one person 40+ inches. If only one person uses the bathroom regularly, a single sink with more space may be preferable.
More Cleaning
Two sinks means twice the cleaning -- two basins, two faucets, two drains, and more counter surface to wipe down. If one sink rarely gets used (as happens in some households), it still collects dust and water spots and needs regular cleaning.
Best Vanity Sizes for Double Sinks
Choosing the right vanity width is critical for a comfortable his and hers sink setup. Too narrow and the sinks feel cramped with minimal counter space. Here are the standard double-sink vanity sizes and how they perform:
| Vanity Width | Counter Per Person | Best For | Our Take |
|---|---|---|---|
| 48 inches | ~18 inches | Very tight spaces | Minimum viable; feels cramped |
| 60 inches | ~24 inches | Standard master baths | Good balance of space and function |
| 72 inches | ~30 inches | Spacious master baths | Most popular; our top recommendation |
| 84 inches | ~36 inches | Large/luxury master baths | Generous space; premium option |
Our recommendation: go with 72 inches if your bathroom can accommodate it. This is the sweet spot where both sinks feel comfortable with enough counter space to keep everyday items within reach. Visit our bathroom vanity guide for more on choosing the right vanity style and configuration.
Popular Sink Styles for His and Hers Vanities
The sink style you choose affects both aesthetics and functionality. Here are the most popular options we install in double-sink bathrooms:
Undermount Sinks
Mounted beneath the countertop with no visible rim. Undermount sinks are the most popular choice for his and hers vanities because they maximize usable counter space and create clean, uninterrupted sight lines. Water and debris can be wiped directly from the counter into the sink without catching on a rim.
Pros:
- Maximum counter space
- Easy to clean around
- Clean, modern look
Cons:
- Requires solid countertop (quartz, granite)
- More complex installation
- Seal can degrade over time
Vessel Sinks
Bowl-shaped sinks that sit on top of the counter surface. Vessel sinks make a bold design statement and come in glass, stone, ceramic, concrete, and metal. They are popular in modern and contemporary bathroom designs. When used in pairs, they create a symmetrical focal point.
Pros:
- Eye-catching design element
- Wide variety of materials
- Easier to install
Cons:
- Takes up counter space
- Higher splash risk
- Higher countertop height
Integrated (Molded) Sinks
The sink basin and countertop are molded from a single piece of material, typically solid surface (like Corian), cultured marble, or quartz composite. There are no seams between the sink and counter, making this the easiest option to keep clean.
Pros:
- Seamless, easy to clean
- No caulk lines to maintain
- Uniform appearance
Cons:
- Fewer material choices
- Limited design variety
- Entire piece must be replaced if cracked
Drop-In (Self-Rimming) Sinks
Drop-in sinks have a visible rim that sits on top of the countertop, holding the basin in place. They are the most affordable and easiest to install, making them a practical choice for budget-friendly double-sink setups. Available in porcelain, stainless steel, and composite materials.
Pros:
- Most affordable option
- Works with any countertop
- Easy to replace
Cons:
- Rim collects grime
- Less counter space
- Dated look in some styles

His and Hers Sink Costs in New Jersey
The total cost for a his and hers sink setup depends on the vanity type, sink style, countertop material, and whether plumbing modifications are needed. Here is what homeowners in the Ewing, Princeton, Hamilton, and Trenton areas can expect:
| Component | Budget | Mid-Range | Premium |
|---|---|---|---|
| Double-Sink Vanity | $1,500 - $3,000 | $3,000 - $6,000 | $6,000 - $12,000+ |
| Sinks (pair) | $150 - $400 | $400 - $800 | $800 - $2,000+ |
| Faucets (pair) | $150 - $400 | $400 - $800 | $800 - $1,500+ |
| Countertop | $300 - $800 | $800 - $2,000 | $2,000 - $4,000+ |
| Plumbing Modifications | $300 - $800 | $800 - $1,500 | $1,500 - $2,500 |
| Installation Labor | $500 - $1,000 | $1,000 - $2,000 | $2,000 - $3,500 |
| Total Estimated Cost | $2,900 - $6,400 | $6,400 - $13,100 | $13,100 - $25,500+ |
These prices reflect 2026 rates in central New Jersey. Costs are typically lower when the his and hers sinks are part of a larger bathroom remodeling project since the contractor is already on-site with plumbing and tile work underway.
Layout Options for His and Hers Sinks
How you arrange the two sinks depends on your bathroom's shape, size, and plumbing. Here are the four most common layouts:
Side by Side (Single Vanity)
Both sinks sit in one continuous vanity cabinet, typically 60 to 72 inches wide. This is the most common and most affordable layout because it requires only one cabinet, one countertop, and plumbing connections on a single wall. The shared vanity can have drawers and cabinets divided evenly between the two sides. This layout works best when you have a long wall with at least 5 feet of uninterrupted space.
Separate Vanities (Same Wall)
Two individual vanities placed on the same wall with a gap between them. The gap can be empty (creating visual breathing room), or filled with a storage tower, open shelves, or a bench. This layout gives each person a distinct, separate station while keeping plumbing on one wall. It also offers more design flexibility since you can choose different vanity styles or sizes for each side -- though matching vanities create the most cohesive look.
Facing Each Other (Opposite Walls)
Each sink is installed on an opposite wall of the bathroom, facing each other across the room. This layout is less common but works well in large, wide master bathrooms. Each person gets their own wall, their own mirror, and complete separation. The downside is that plumbing must be run to two walls, which increases cost. This layout is most practical when the bathroom is at least 8 to 10 feet wide.
L-Shape or Corner Configuration
One sink on each arm of an L-shaped vanity that wraps around a corner. This layout maximizes counter space and works well in bathrooms with two adjacent walls available. The corner area between the sinks provides shared storage or a display area. L-shaped vanities are typically custom-built to fit the exact dimensions of your bathroom.
Choosing the Right His and Hers Vanity
With so many options, narrowing down the right vanity for your double-sink bathroom comes down to these key factors:
Measure Your Bathroom First
Measure the available wall space where the vanity will go. Subtract clearances for the toilet (at least 15 inches from vanity edge to toilet center), door swings, and shower access. The remaining space determines your maximum vanity width. Leave at least 4 inches of counter space on the outside edges and 6 inches between the two sinks for comfortable use.
Prioritize Storage
Think about what each person stores in the bathroom. If both people have extensive grooming routines, choose a vanity with deep drawers and ample cabinet space. Drawer dividers and pull-out organizers help maximize the storage that each person has. Floating vanities sacrifice some storage for a lighter visual look -- consider adding a separate storage cabinet or medicine cabinet to compensate.
Match Your Bathroom Style
Your vanity should complement the rest of the bathroom design. Shaker-style double vanities work in traditional and transitional bathrooms. Flat-panel vanities suit modern spaces. Furniture-style vanities add character to larger bathrooms. The countertop material (quartz, granite, marble) should also match or coordinate with your overall design.
Consider the Mirror and Lighting
His and hers sinks need proper mirror and lighting placement. Options include one wide mirror spanning both sinks, two separate mirrors (one per sink), or two medicine cabinets with mirrored fronts. Lighting should illuminate each person's face evenly -- wall sconces between the mirrors or a long vanity light bar work best. Avoid a single overhead light that creates shadows.
Think About Resale
If you plan to sell your home in the next 5 to 10 years, choose neutral colors and timeless styles. White, gray, and navy vanities have the broadest buyer appeal. Avoid very trendy finishes that may look dated quickly. Undermount sinks and quartz countertops are consistently the most in-demand combination among NJ homebuyers.

Frequently Asked Questions
Are his and hers sinks worth it?
Yes, for most couples sharing a master bathroom. His and hers sinks eliminate morning bottlenecks, give each person their own space and storage, and increase home resale value. The investment is worthwhile if your bathroom has at least 48 inches of wall space (60-72 inches is ideal) and your budget allows for the additional plumbing and vanity costs.
What is the minimum vanity size for his and hers sinks?
The minimum vanity size for comfortable his and hers sinks is 60 inches (5 feet). At this width, each person gets about 30 inches of space including their sink basin and some counter area. A 72-inch vanity is the most popular choice because it provides more counter space between and beside the sinks. Vanities up to 84 inches are available for larger master bathrooms.
How much do his and hers sinks cost in NJ?
Installing his and hers sinks as part of a bathroom remodel in New Jersey typically costs between $3,000 and $12,000 for the vanity, sinks, faucets, and installation. A stock double-sink vanity starts around $1,500-$3,000, semi-custom runs $3,000-$6,000, and fully custom vanities range from $6,000-$12,000+. Plumbing modifications add $500-$2,000 if new drain lines are needed.
Can you put two sinks in a small bathroom?
It depends on the bathroom size. You need a minimum of 48 inches of vanity wall space, plus room for the toilet, shower/tub, and door clearances. In bathrooms under 50 square feet, two sinks can make the space feel cramped. A better option for small bathrooms is a single large sink with more counter space, or two separate smaller vanities placed on different walls.
What sink style is best for a his and hers vanity?
Undermount sinks are the most popular choice for his and hers vanities because they maximize counter space and create clean sight lines. They pair well with quartz and granite countertops. Vessel sinks make a strong design statement but reduce usable counter space. Integrated sinks (molded into the countertop) are the easiest to clean but limit material and style options.
