45" Bathroom Vanities

45-Inch Bathroom Vanities for Hard-to-Find Spaces

Searching for a 45-inch bathroom vanity usually means standard retail sizes do not fit the room. DISAR created this collection for a renovation where 42 inches leaves wasted space and 48 inches is too wide. It gives homeowners, designers, and contractors a ready-to-ship alternative to expensive custom cabinetry.

Explore single- or double-sink Shaker configurations in White, Gray, Navy Blue, and Natural Oak. Construction includes solid wood frames, heavy-duty plywood cabinet boxes, solid wood dovetail drawers, and soft-close doors and drawers. Depending on the layout, options may include left or right drawer banks, makeup desks, and tall linen cabinets.

Choose a base-only vanity for custom stone or a complete vanity with Carrara quartz and ceramic sinks. In-stock products ship from our Wharton, New Jersey warehouse with free nationwide delivery.

Compare 45-inch base-only vanities or 45-inch vanities with quartz tops to choose the right configuration for your project.

45-Inch Cabinet and 46-Inch Countertop Sizing

The cabinet base measures 45 inches wide. Complete countertop configurations use an approximately 46-inch-wide top to provide about one-half inch of overhang on each side. Customers may search for this configuration as a “45-inch bathroom vanity,” “46-inch bathroom vanity top,” or “45-inch vanity with 46-inch countertop.” Always review the individual product dimensions before installation.
