Understanding Double Sink Vanities
Double sink vanities are a popular choice for shared bathrooms, offering increased convenience and functionality. They are typically available in various sizes, from compact 48-inch vanities to expansive 72-inch versions. The vanity size you choose will depend on the available bathroom space and your specific needs.
Choosing the right vanity size is just as important as selecting the right sink basin. Both elements need to complement each other to ensure that your bathroom is both functional and aesthetically pleasing.
48-Inch Double Sink Vanity and Sink Basin Selection
Ideal Space and Basin Dimensions
The 48-inch double sink vanity is perfect for smaller bathrooms or bathrooms with limited space. This size generally accommodates two basins with widths ranging from 16 to 18 inches (40 to 45 cm) each.
When selecting sink basins for a 48-inch double sink vanity, consider basins that are shallower in depth—typically around 6 to 7 inches. Shallow basins help optimize available space while ensuring comfortable functionality. If you’re looking for a minimalist or modern design, consider opting for square or round-shaped basins, as they complement the smaller scale of this vanity.
Key Tips for Choosing the Right Sink Basin:
- Width: 16 to 18 inches per basin
- Depth: 6 to 7 inches
- Shape: Round or square basins work best in a 48-inch vanity
- Material: Ceramic is a great budget-friendly option that adds classic appeal
Recommended Materials and Shapes
- Material: For a 48-inch vanity, ceramic sink basins are an excellent choice as they are durable, easy to clean, and cost-effective. If you prefer a modern touch, stainless steel can offer sleek lines and a contemporary feel.
- Shape: Round basins are ideal for a more subtle, organic design, while square basins can add a sharp, clean aesthetic to the space.
60-Inch Double Sink Vanity and Sink Basin Selection
Ideal Space and Basin Dimensions
A 60-inch double sink vanity is perfect for standard-sized bathrooms, typically ranging between 100 to 150 square feet. This size provides ample counter space, and each sink basin usually measures between 18 to 20 inches (45 to 50 cm) in width. The depth of the sink basins should fall between 7 to 8 inches, offering enough space for daily use without feeling overly bulky.
This size of vanity works well with various sink shapes, including round, oval, and square basins. An oval basin can add a sense of elegance to the space, while square basins can contribute to a modern, geometric look.
Key Tips for Choosing the Right Sink Basin:
- Width: 18 to 20 inches per basin

72-Inch Double Sink Vanity and Sink Basin Selection
Ideal Space and Basin Dimensions
The 72-inch double sink vanity is designed for larger bathrooms with more square footage. Each basin typically measures 20 inches (50 cm) or wider, offering plenty of room for both functionality and visual appeal. The depth of the sink basins ranges from 8 to 10 inches, providing a deeper and more spacious basin compared to smaller vanities.
Because of the larger size, 72-inch vanities are an excellent match for deep, wide sink basins. Consider rectangular or oval basins for a more luxurious feel, or stick with square basins for a modern and bold look.

Material Considerations
The material of your sink basin plays a significant role in both its durability and aesthetic. Here are some common materials to consider:
