Bathroom Vanity Cabinets: Sizes, Materials, and What to Consider

Bathroom cabinetry gets far less design attention than kitchen cabinetry, but it deals with a tougher environment — humidity, splashing, and usually a much smaller footprint to work with. A few things matter more here than they do in a kitchen.

Standard Vanity Sizes

Vanities commonly run 24 to 72 inches wide in standard increments, with 30-36 inches being the most common single-sink size. For a shared or primary bathroom, a 60-72 inch double-sink vanity is typical when space allows.

Material Matters More in a Bathroom

Humidity and moisture make material choice more consequential than in a kitchen. Solid wood construction with a quality moisture-resistant finish holds up well; painted MDF options can be more prone to swelling at the toe-kick and base over years of exposure to splashing and mopping.

Countertop Choice for Vanities

Quartz is a particularly strong fit for bathroom vanities — non-porous, no sealing required, and resistant to the toiletries and cosmetics that stain more porous stone over time. Marble is a popular look for a primary bathroom but needs the same sealing diligence as a kitchen application, arguably more so given daily product spills.

Storage Planning for Small Bathrooms

• Drawers hold toiletries more accessibly than doors with shelves behind them
• A furniture-style vanity with open shelving below works well in smaller powder rooms where full storage isn't needed
• Built-in outlets inside a drawer keep hair tools charged and off the counter
