45" Bathroom Vanities Base Only

45-Inch Bathroom Vanity Base Only for Custom Countertops

Choose a 45-inch bathroom vanity base only when your project requires custom quartz, marble, granite, porcelain, or another countertop material. This rare width is ideal for a renovation where 42 inches leaves wasted space and 48 inches is too wide while giving your fabricator control over sink placement, faucet drilling, edge profile, and stone color.

DISAR base-only vanities feature solid wood frames, heavy-duty plywood cabinet boxes, solid wood dovetail drawer boxes, and soft-close hardware. Available Shaker finishes include White, Gray, Navy Blue, and Natural Oak, with configurations that may include drawer storage, makeup desks, or linen cabinetry.

No countertop or sink is included in this collection. Cabinets are stocked in Wharton, New Jersey and ship free nationwide in secure freight packaging.

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.
