Double sink vanities transform busy morning routines by giving each person dedicated space for grooming and preparation. For Chicago couples and families sharing master bathrooms, the investment in a double vanity eliminates the daily negotiation over sink access. Beyond convenience, double vanities add significant value to homes and create the spa-like bathroom experience that buyers expect in updated properties.

When Double Vanities Make Sense

Evaluate whether double sinks fit your situation:

Household composition matters most. Couples with overlapping morning schedules benefit immediately. Single occupants rarely need double sinks regardless of bathroom size.

Bathroom dimensions determine feasibility. Double vanities require minimum 60 inches of wall space—preferably 72 inches or more for comfortable use. Smaller bathrooms may sacrifice too much floor space.

Plumbing considerations affect cost. Existing single-sink bathrooms need additional drain and supply lines for second sinks. New construction or gut renovations incorporate this easily.

Resale value increases with double vanities in master bathrooms. Chicago buyers expect this feature in homes priced above $400,000. The upgrade often returns 60-80% of investment at sale.

Daily routine analysis reveals true need. If one person showers while the other uses the sink, double vanities provide less benefit than separate shower timing suggests.

Double Vanity Size Options

Standard dimensions accommodate various bathroom sizes:

60-inch double vanities represent the minimum practical width. Two sinks fit tightly with limited counter space between. Works in smaller master bathrooms where space is constrained.

72-inch double vanities provide comfortable spacing. Each user gets dedicated counter area with shared center storage. Most popular size for Chicago master bathroom renovations.

84-inch double vanities offer generous proportions. Ample counter space, larger sinks possible, and substantial storage capacity. Requires larger bathroom footprint.

96-inch and longer vanities suit luxury master bathrooms. May include seated makeup area between sinks or extensive storage towers. Common in suburban Chicago custom homes.

Depth considerations:

- Standard 21-22 inch depth works for most bathrooms

- Compact 18-inch depth saves space in tight layouts

- Extended 24-inch depth provides more counter and storage

Height options:

- Standard 32-34 inches suits most users

- Comfort height 36 inches reduces bending

- ADA-compliant heights accommodate accessibility needs

Double Vanity Layout Options

Configuration affects functionality and aesthetics:

Single cabinet with two sinks places both basins in one continuous unit. Unified appearance with shared storage below. Most common and typically most economical approach.

Two separate vanities with gap creates distinct his-and-hers stations. Storage tower or open shelving fills center space. Allows different heights or styles if desired.

Floating double vanities mount to wall without floor contact. Modern aesthetic with easier floor cleaning. Requires structural wall support for both sections.

L-shaped configurations wrap corners in larger bathrooms. One sink on each wall with corner storage. Maximizes space in square bathroom layouts.

Furniture-style double vanities on legs create traditional look. Open space below adds visual lightness. Less storage than full cabinet bases.

Sink Styles for Double Vanities

Basin selection affects both function and appearance:

Undermount sinks create clean countertop lines. Easy to wipe debris directly into basin. Most popular choice for contemporary and transitional bathrooms. Requires solid surface countertops (quartz, granite, marble).

Drop-in sinks feature rim that sits on countertop surface. Easier installation and allows laminate countertops. Rim collects water and debris—slightly harder to clean.

Vessel sinks sit atop the counter as decorative bowls. Statement-making appearance but reduces usable counter space. Requires vessel-height faucets. Splashing can be an issue.

Integrated sinks form seamlessly with countertop material. No seams to collect grime. Available in solid surface, concrete, and some quartz options. Higher cost but ultimate cleanability.

Trough sinks span extended length with single drain. Two faucets share one long basin. Unique appearance suits modern and industrial aesthetics.

Sink sizing for doubles:

- Rectangular undermounts: 18-21 inches wide typical

- Round undermounts: 15-17 inch diameter

- Allow minimum 6 inches between sink edges

- Consider faucet spread requirements
