Double Vanity Cost in NJ: What Two Sinks Actually Cost
A double vanity is one of the most-requested upgrades in NJ master bathroom remodels. It is also one of the easiest to over-spend or under-spend on. The same 72-inch footprint can cost $4,500 in stock cabinets and cultured marble, or $14,000 in custom paint and quartz. Both are valid choices for different homes and different homeowners.
I am Enrique Lopez, owner of Custom Kitchens By Lopez in Freehold Township, NJ. We have built and installed hundreds of double vanities across Monmouth, Ocean, and Middlesex Counties. This guide gives you actual numbers for each tier — stock, semi-custom, custom — plus what the second sink really adds compared to a single vanity, and how to plan the install correctly.
The honest answer: a double vanity in NJ costs $2,500 to $15,000+ installed. Most master bathroom clients in our portfolio spend $5,500 to $9,500 for a quality 72-inch double vanity, installed.
Double Vanity Cost at a Glance
These are real NJ numbers from quotes we have written and projects we have delivered.
| Size | Tier | Total NJ Cost (Installed) |
|---|---|---|
| 60-inch stock | Home Depot, Lowe's, Wayfair | $2,500 - $4,500 |
| 60-inch semi-custom | KraftMaid, Bertch | $4,500 - $6,500 |
| 60-inch custom-built | Local NJ shop | $6,000 - $9,500 |
| 72-inch stock | Home Depot, Lowe's | $3,500 - $5,500 |

What "Double" Actually Adds vs a Single Vanity
The cost difference between a single and a double of the same width is real but smaller than people expect. The biggest add-on is the second sink and faucet plus the plumbing for the second drain.
Compared to a 72-inch single vanity:
| Add-On | NJ Cost | Notes |
|---|---|---|
| Second sink and rough-in | $400-$1,200 | Drain + 2 supply lines + faucet rough-in |
| Second faucet (matching) | $200-$1,000 | Mid-range to designer |
| Second sink basin (undermount or drop-in) | $150-$600 | Quality varies |
| Plumbing labor for second sink | $400-$900 | NJ rate, depends on wall access |
| Cabinet drawer count adjustment | -$100 to +$300 | Less storage but specialized drawers around plumbing |
| Total double-vs-single premium | $1,250 - $4,000 | For a 72-inch vanity |
If your existing wall has plumbing only on one side, expect to be at the upper end of the range — opening drywall and adding water and drain lines for the second sink takes longer than a vanity that already has rough-in on both sides.
Stock vs Semi-Custom vs Custom Doubles
The same 72-inch vanity at three quality tiers — here is what changes between them and where the price gap comes from.
Stock Double Vanity (60-72 inch, $2,500-$5,500 installed)
Where they come from: Home Depot, Lowe's, Wayfair, Build.com, Costco, IKEA. Most are particleboard or MDF box with thermofoil or veneer doors. Cultured marble or basic granite tops are common.
What you get:
- Standard 60-inch or 72-inch widths only
- Standard depths (21 or 24 inches)
- Limited finishes (white, gray, espresso, navy)
- Matching mirror and medicine cabinet usually available
- Cultured marble or basic stone top integrated or as packaged add-on
- Faucets included or sold separately
Honest take: Stock works for budget-conscious master bathrooms. Plan to replace within 8-15 years due to NJ humidity affecting MDF box construction. The cultured marble tops yellow over time and the thermofoil doors delaminate around the sink first.
Semi-Custom Double Vanity (60-72-84 inch, $4,500-$8,000 installed)
Top NJ brands:
- KraftMaid (sold through Lowe's): Strong veneer and paint program, plywood box construction available. Lead time 4-6 weeks.
- Bertch (sold through bath showrooms): All-wood construction standard, strong custom paint program. Lead time 5-8 weeks.
- Wellborn (select dealers): All-wood construction, customizable. Lead time 6-8 weeks.
What customization gets you:
- Non-standard widths in 3-inch increments
- 50-200 paint and stain colors
- Plywood box construction (vs MDF in stock)
- Soft-close drawers and doors as standard
- Drawer organizers, hidden outlet drawers, tip-out trays
- Tower cabinets or linen towers can be ordered as matching companion pieces
- Choice of door style (shaker, slab, raised panel, beadboard)
Honest take: Semi-custom is the sweet spot for most NJ master bathrooms. You get plywood construction and customization at 50-65 percent of fully-custom pricing. The 4-8 week lead time is the main constraint.
Custom Double Vanity (Any Size, $7,500-$15,000+ installed)
What custom actually means:
- Exact dimensions to match your bathroom
- Custom paint mixes, exotic veneers, hand-distressed finishes
- Integrated outlets in drawers, USB charging stations, lighted interiors
- Drawers that wrap around plumbing
- Furniture-grade construction with solid wood face frames and dovetailed drawer boxes
- Coordinated companion pieces (linen tower, mirror frame, medicine cabinet) built simultaneously
When custom makes sense:
- Non-standard layout (sloped ceiling, wall jog, plumbing in awkward location)
- High-end ($30K+) bathroom remodel with everything coordinated
- Unique storage needs that stock and semi-custom cannot deliver
- Bathroom is the visual centerpiece of a luxury master suite

Where the Money Should Go
If your double-vanity budget is limited, prioritize spending in this order:
1. Box Construction (Top Priority)
Plywood beats MDF beats particleboard. The cabinet box is the wear part — NJ humidity attacks particleboard and MDF first. Plywood adds $400-$800 to a 72-inch vanity over particleboard. It is the highest-value upgrade you can make.
2. Soft-Close Hardware
Soft-close drawers and doors are now expected on master bathroom vanities in homes priced above $400K. Premium hinges and slides (Blum, Hettich) outlast the cabinet box. Standard in semi-custom and above.
3. Quartz Countertop
For a long-span double vanity, quartz reads more cohesive than naturally-variable materials. It also requires no sealing and resists stains from cosmetics, perfumes, and toothpaste. Mid-range Caesarstone or Silestone in plain white or marble-look is the right answer for most master bathrooms.
4. Quality Faucets
The faucets are touched daily. Spend at least $300-$500 per faucet even on a budget double vanity. For NJ-specific brand comparisons, see our Moen vs Delta faucets guide and Moen vs Delta vs Kohler faucets guide.
5. Undermount Sinks
Undermount sinks make countertop cleaning dramatically easier (no dirt-trap rim) and look more upscale. Adds $200-$400 per sink in fabrication. Worth it.
6. In-Drawer Outlet
A power outlet inside one of the upper drawers transforms the vanity for daily use — hair tools, electric toothbrushes, shavers all stay plugged in and out of view. Adds $150-$350 to install. One of the highest daily-utility upgrades.
Common Double Vanity Mistakes in NJ
After 20+ years installing double vanities, here are the most expensive mistakes to avoid.
1. Going 60 Inches When 72 Fits
If your wall is 75 inches wide, a 72-inch vanity gives you a 1.5-inch reveal on each side. A 60-inch vanity in the same space looks small and leaves awkward dead space. Go as wide as the wall reasonably allows.
2. Not Planning Plumbing Locations Early
If you are converting from a single to a double, plumbing for the second sink must be roughed in before drywall closes back up. Make this decision during framing, not during finish work.
3. Mismatched Faucet Heights
The two faucets need to match in height to look intentional. Pairing a tall vessel-style faucet with a low standard faucet looks like a mistake. Pick matching faucets in matching finishes.
4. Skimping on Drawer Quality
Bathroom drawers see daily use and constant humidity. Generic ball-bearing slides fail within 5-7 years in NJ. Specify Blum or Hettich soft-close as a baseline, even on a stock vanity if possible.
5. Wrong Counter Height for Users
Comfort-height vanities (36 inches) match kitchen counters and have become standard for adults. Standard-height (32 inches) feels low and outdated for most adults. Pick comfort-height unless you have specific kid-bathroom needs.
6. Over-Specifying the Mirror
Designer mirrors can run $1,500-$3,000 for a pair. Quality off-the-shelf mirrors from Wayfair or Pottery Barn at $200-$500 each look 90 percent as good for 20 percent of the cost.
