You’re standing there, toothbrush in hand, waiting. Your partner is meticulously flossing, oblivious to the fact that you’ve got a 9:00 AM meeting and a face that needs washing. This is the exact moment people decide they need his and hers bathroom sinks. It feels like the ultimate luxury, right? A symbol that you’ve finally "made it" in the world of home ownership. But honestly, after years of looking at floor plans and seeing how people actually live in their homes, the double vanity isn't always the marriage-saver it’s cracked up to be.
The Reality of the Double Vanity Dream
Let’s be real. We’ve been sold a specific image of domestic bliss. It involves a massive slab of marble, two gleaming porcelain bowls, and two people smiling at each other while they apply moisturizer. In the industry, we call this a double vanity, but most homeowners just call it "getting some breathing room."

The problem is that a standard his and hers bathroom sinks setup requires a lot of real estate. You need at least 60 inches of horizontal space just to fit two basins comfortably. If you try to squeeze them into a 48-inch vanity, you end up with zero counter space. You’re basically trading the ability to set down a hair dryer for the ability to have two drains. It’s a trade-off many people regret once the honeymoon phase of the renovation wears off.
Think about how you actually use the bathroom. Are you really brushing your teeth at the exact same second? Most couples have staggered schedules. One person is a morning lark, the other is a night owl. If you’re never at the sink at the same time, you’ve just paid double for plumbing, double for faucets, and lost three feet of precious counter space for a sink that stays dry 23 hours a day.
Space: The Final Frontier
I’ve seen bathrooms where the double sink was forced into a tight corner. It’s claustrophobic. If you’re bumping elbows while trying to spit out toothpaste, the "his and hers" aspect is a total wash. You need "elbow room"—literally. Architects often recommend a 72-inch vanity if you want a truly premium experience. This allows for a bank of drawers in the middle, which is where the real value lies.
Storage is the secret sauce. A single sink vanity usually offers more drawers and cabinet space than a double sink vanity of the same size. Why? Because plumbing takes up room. Two sinks mean two P-traps, two sets of supply lines, and two massive chunks of your under-sink storage gone. If you have a small master bath, a large single sink with massive drawers on either side is almost always the smarter move.

Why His and Hers Bathroom Sinks Still Win
Despite the space issues, there is a reason these things are everywhere. It’s not just about the sinks. It’s about the territory.
Having your own sink means you don't have to look at someone else's beard trimmings or toothpaste globs. It’s a psychological boundary. "This is my zone. I keep my skincare here, my razor there, and I don't have to move your stuff to find my deodorant." For many, that mental peace is worth the loss of counter space.
Resale Value and the "Hotel Feel"
If you’re planning to sell your house in the next five years, listen up. Real estate agents will tell you that a master suite without his and hers bathroom sinks is a harder sell. It’s become an expected standard in modern American homes. Potential buyers walk into a master bath, see one sink, and immediately think "inconvenience." It’s a box that needs to be checked.
There’s also the aesthetic. A long vanity with symmetrical mirrors and lighting looks balanced. It feels like a high-end hotel. Brands like Kohler and Moen have built entire marketing empires around this symmetry. When you see a double vanity with wall-mounted faucets and vessel sinks, it feels intentional and curated.
The Cost of Doubling Up
Nobody likes to talk about the "plumbing tax." Installing two sinks isn't just buying an extra bowl.
- The Countertop: Custom-cutting two holes in quartz or granite costs more than one.
- The Hardware: High-end faucets aren't cheap. If you’re eyeing a Delta Cassidy or a Brizo Luxe Gold set, you’re now buying two. That’s an extra $400 to $900 right there.
- The Labor: Your plumber has to run twice the lines. If you’re converting a single sink to a double, they have to open up the wall to tie into the vent and waste lines. It’s messy and expensive.
Design Trends You Should Actually Care About
If you’re committed to the double sink life, don't just stick two drop-in sinks in a laminate counter. We’re seeing a shift toward more integrated looks.
The Trough Sink
This is a cool middle ground. It’s one long, wide basin with two separate faucets. It looks modern, it’s easier to clean because there’s no seam between two separate sinks, and it feels less cluttered. It’s a great way to get the functionality of his and hers bathroom sinks without the visual breakup of two individual bowls.

Floating Vanities
Wall-mounted vanities make a small bathroom feel huge. You can see the floor all the way to the wall, which tricks your brain into thinking the room is bigger. Just make sure your contractor reinforces the wall; a 60-inch stone countertop with two sinks is incredibly heavy. I’ve heard horror stories of floating vanities sagging or pulling away from the studs because they weren't properly braced with steel brackets.
Counter-Intuitive Advice: The "Extra Large" Single
Here’s a hot take: Some of the most functional master bathrooms I’ve seen lately have ditched the double sink for one massive, offset sink. By putting a single sink to one side of a 60-inch vanity, you create a huge, unbroken workspace on the other side. This is perfect for people who use a lot of "tools"—hair straighteners, makeup palettes, or shaving kits. You get the storage of a single-sink cabinet and a massive "dry zone."
Honestly, most of us spend more time "getting ready" than we do actually using the running water. If you spend 20 minutes doing hair and 30 seconds rinsing your face, why prioritize the sink over the counter?
Common Mistakes to Avoid
- Poor Lighting: People often put one light fixture over each mirror. This creates shadows in the middle of your face. Side-mounted sconces are better for tasks like shaving or makeup, but you need a wide vanity to fit three sconces (one on each side and one in the middle).
- Wrong Height: The "standard" vanity height used to be 30-32 inches. That’s way too low for most adults. Nowadays, "comfort height" vanities are 36 inches—the same as kitchen counters. If you’re installing his and hers bathroom sinks, go with the 36-inch height unless you’re particularly short. Your back will thank you.
- Ignoring the Outlets: You have two people. You have two electric toothbrushes, maybe two hair dryers, and a phone charger. Do not skimp on the outlets. Get them installed inside the drawers if you can, to keep the cords off the counter.
Actionable Steps for Your Renovation
Before you tear out your old vanity, do a "usage audit" for three days. Note how many times you and your partner are actually at the sink at the same time. If it’s less than once a day, you might be better off with a single sink and better storage.
If you decide to go with his and hers bathroom sinks, measure your space three times. If you have less than 60 inches, stop. Don't do it. You’ll hate the lack of counter space. If you have 72 inches or more, go for it, but prioritize a vanity with a center stack of drawers.
Check your local plumbing codes as well. Some jurisdictions have specific requirements for "double-wye" connections in the wall. It’s better to find this out before you buy a vanity that doesn't align with your existing pipe locations.
Lastly, think about the finish. Polished chrome shows every single water spot and fingerprint. If you’re sharing a space, brushed nickel or matte black are much more forgiving for a high-traffic area.
Choosing a bathroom layout is about more than just what looks good on Pinterest. It’s about how you move in the morning when you’re half-asleep and grumpy. Choose the setup that makes your routine easier, not the one that just looks symmetrical in a photo.
Next Steps:
- Measure your existing vanity area to see if a 60-inch or 72-inch unit will fit without blocking the door or toilet.
- Research "trough sinks" as a modern alternative to the traditional two-bowl setup.
- Consult with a plumber to get a quote on the "rough-in" costs for adding a second drain line.
