Having two sinks in your bathroom provides convenience and flexibility for busy households. Double bathroom sinks allow two people to get ready at the same time, avoiding the morning rush hour at the vanity. They also provide symmetry and balance to create a luxe, spa-like ambience.

Benefits of Double Bathroom Sinks

Installing double bathroom sinks offers many advantages over a single vanity:

More Privacy and Elbow Room

With two sinks, each person has their own space to spread out toiletries and get ready without jostling for room. Side-by-side sinks eliminate privacy concerns and remove arguments over storage.

Faster Morning Routines

Dual sinks speed up time-crunched morning rituals so family members aren’t waiting their turn. Couples can shave, apply makeup, and style hair simultaneously to avoid running late.

Customized Storage

His and hers sinks allow for personalized organization and clutter-free countertops. Each person can arrange their own products without interfering with the other’s space.

Easy Resale Value

Bathrooms with double vanities offer convenience buyers want. This investment can increase home value and shorten selling time.

Symmetry and Balance

A double sink vanity provides visual symmetry for a pulled-together, spa-like look. The balance of two sinks makes the room feel more open and elegant.

More Countertop Space

Compared to one large sink, two individual sinks give you more overall countertop area to work. There’s plenty of room to spread out and multitask on grooming tasks.

Double Sink Configurations

There are several setups and designs to consider when planning your dual vanity:

Linear Side-by-Side

Two same-sized rectangular sinks sit next to each other in a linear configuration. This traditional look works well with longer vanities in big baths.

Angled Side-by-Side

Similar to linear but with the sinks staggered diagonally. Angled placement adds interest while keeping a streamlined profile.

Stacked Double Sink

One sink sits atop the other along the same plumbing wall. Stacked orientation conserves space in narrow bathrooms.

His and Hers Split

Separate standalone sinks placed across from one another against opposite walls. This layout is perfect for large master ensuites.

Tower Double Sink

Sinks are positioned back-to-back in the center of the vanity like a tower. The tower divider provides separation and privacy.

Basins in Solid Surface/Quartz

Sinks carved out of solid surfacing or natural stone for an integrated, seamless look. Durable and easy to clean.

Vessel Sinks

Vessel basins sit on top of the counter as decorative focal points. Their open design creates an airy, spa vibe.

Countertop Materials

Choosing the right countertop material is key to a functional, on-trend double vanity:


Quartz counters are durable, stain-resistant, and easy to clean. Popular options like Caesarstone come in many colors to match any decor.


Elegant marble countertops add timeless beauty with unique natural veining in each slab. Needs regular sealing to prevent stains and etching.


Granite is a classic choice that brings natural pattern and color. More maintenance required than quartz but less than marble.


Affordable laminate counters mimic the look of stone with seamless installation and lots of variations. Avoid liquids to prevent swelling.

Solid Surface

Acrylic-based solid surface material resists scratches and stains. Brands like Corian have integral sinks for a sleek look.

Butcher Block

Butcher block offers a traditional vibe with warmth and character. Needs oil sealing to repel water and prevent bacteria.


Concrete makes a statement with its raw, industrial edge. Can be colored, stained, or polished. Requires regular sealing.

Double Sink Vanities

The vanity you choose impacts the room’s storage and style. Consider these popular options:

Freestanding Furniture-Style

Freestanding vanities have furniture styling to anchor the space. Look for solid wood frames, turned legs, and decorative hardware.

Built-In Cabinetry

Custom built-in cabinetry creates seamless storage around the sinks. Shaker-style doors and internal organization keep items tidy but accessible.

Metal Base Cabinets

Sturdy metal cabinets come in chrome, bronze, or powder-coated colors. Sleek metal pairs well with stone or concrete countertops.

Mirrored Cabinets

Mirrored cabinets visually enlarge small bathrooms. Integrated lighting creates a glamorous styling focal point.

Antique Furniture

Refinished vintage dressers or cabinets make charming vanities with timeworn character. Add new stone tops and sinks for an updated mix.

Custom Wood

One-of-a-kind custom cabinetry in exotic woods or with decorative carvings allows for personalized style.

Faucet Configurations

Choose from several faucet setups to complement your double vanity:

Two Individual Centerset Faucets

Classic three-hole, 4-inch centerset faucets mounted singly for each sink. Provides totally separate controls.

Single Faucet Between Sinks

One wide faucet placed in the middle operates both sinks. Streamlined look but limited controls.

Two Shared End Faucets

Faucets on the outer edges of the vanity control inside sinks. Convenient operation without a center divider.

Two Vessel Faucets

Faucets mounted on the countertop behind raised vessel sinks. High spouts flow into basins.

Wall-Mount Faucets

Minimalist wall-mounted taps positioned over each sink. Creates uncluttered countertop space.

Design Tips

Follow these tips for a stylish, functional double vanity design:

  • Choose two sinks the same size and style for visual symmetry. Mixing shapes and sizes looks disjointed.
  • Allow at least 36 inches between the centers of sinks so users don’t bump into one another.
  • Incorporate task lighting above or around each mirror to evenly illuminate faces for grooming.
  • Double up on electrical outlets—one for each side eliminates fighting for plug space.
  • Select a countertop material that withstands water and daily wear and tear. Avoid high-maintenance surfaces prone to damage.
  • Include a makeup organizer or tray on each vanity top to corral small items. Under-sink drawers provide concealed storage.
  • Floating wood or metal shelving above the sinks accommodates folded towels and decorative items.
  • Pick faucets with widespread handles that don’t interfere with one another or take up too much space.
  • Choose low-profile rectangular or square vessel sinks if using a vessel design. Round bowls overlap and reduce room.
  • Install drawer organizers and pull-out trays for smart storage inside vanity cabinets.

Purchasing Double Sinks

You can buy complete double vanity sets or mix and match components:

  • Vanity sets include cabinets, countertops, sinks, faucets, and sometimes mirrors. All-in-one for faster installation.
  • Purchase countertops and sinks separately to customize materials and finishes.
  • Sinks come as undermount, drop-in, or vessel style. Compare installation needs.
  • Shop clearance sales or vintage and thrift stores to save on unique secondhand vanities.
  • Hire a skilled contractor for structural changes, plumbing, wiring, installing cabinets, and countertops.

Installing Double Sinks

With careful planning, you can handle installing double sinks as a DIY project:

Gather Supplies

  • Vanity, countertop, sinks, faucets, drain assemblies, supply lines, primer, adhesive, caulk, tools, etc. Make sure all components are onsite before starting.

Prepare the Space

  • Demolish and remove the old vanity. Turn off water supply lines. Inspect walls for needed repairs.

Install New Plumbing

  • Run drain pipes and supply lines to new sink locations. Provide adequate pipe length for attachments.

Mount Vanity Cabinet

  • Place in desired location, level, and anchor to studs in the wall. Check doors and drawers operate smoothly.

Cut Countertop

  • Make sink cutouts using a template and router. Cut outs should allow proper support underneath.

Set Sinks and Faucets

  • Set sinks by applying adhesive around the rims. Attach faucets and drain assemblies. Connect water supply.

Finish Plumbing Connections

  • Link drain pipes, supply lines, and faucet hookups. Check for leaks and proper water flow.

Caulk and Seal

  • Apply caulk around sinks and backsplash. Wipe away excess for a tidy finish.

Double Sink Maintenance

Follow these tips for keeping your dual vanities looking like new:

  • Daily wipe downs with a soft, damp cloth prevents buildup of dirt and grime in hard-to-reach areas.
  • Disinfect sinks regularly with a non-abrasive bathroom cleaner to kill germs and prevent staining.
  • Rinse sinks after each use to wash away hair, toothpaste, and other gunk down the drain.
  • Clean mirrors using glass cleaner and a microfiber cloth to cut through splatter and water spots.
  • Organize toiletries in buckets, trays, or drawer organizers to limit clutter and simplify cleaning.
  • For solid surface or stone, use sealers to protect the finish and make cleaning easier. Reseal annually.
  • Avoid placing super-hot pans or cleaners directly on the countertop. Use trivets and dilute cleaners to prevent etching.
  • Tighten or replace faulty faucet parts like washers and o-rings to stop annoying drips.
  • Unclog drains regularly with a zip-it tool, boiling water, or diluted drain cleaner to prevent backups.
