18-Inch Unfinished Shaker Vanity Base Cabinet
The UVB18 is an 18-inch-wide Unfinished Shaker Vanity Base Cabinet featuring one drawer, one door, and one adjustable shelf. It adds practical drawer and cabinet storage beside a vanity sink base while maintaining the bathroom-friendly 21-inch cabinet depth.
At just 21 inches deep, this cabinet provides more comfortable clearance than a standard 24-inch kitchen base cabinet while still offering generous storage for everyday bathroom essentials.
Why Choose an 18-Inch Vanity Base Cabinet?
Choose the UVB18 when you want more usable storage than a
15-Inch Unfinished Shaker Vanity Base Cabinet
provides and your bathroom layout has room for the additional width.
Like the other vanity base cabinets in this series, it is commonly installed beside a vanity sink base to add one convenient drawer above enclosed storage. It offers an economical alternative to a vanity drawer base when one drawer provides all the organization you need.
Common Bathroom Storage Uses
The top drawer is ideal for storing:
- Toothbrushes and toothpaste
- Razors and shaving supplies
- Makeup and cosmetics
- Hair accessories
- Everyday toiletries
- Small grooming tools
The cabinet below is perfect for:
- Toilet paper
- Bathroom cleaning supplies
- Hair dryers and styling tools
- Extra toiletries
- Towels and washcloths
- Taller bottles and bathroom products
The adjustable shelf can be repositioned or removed whenever additional vertical storage is needed for taller bottles, cleaning products, or grooming tools.
18-Inch vs. 15-Inch Vanity Base Cabinet
The
15-Inch Unfinished Shaker Vanity Base Cabinet
is an excellent choice when the bathroom layout is tighter.
Choose the UVB18 when both widths fit comfortably and you want more drawer and cabinet storage. The additional three inches provide greater flexibility for organizing toiletries, towels, cleaning supplies, and hair tools.
Designed for Everyday Bathrooms
Our Partial Overlay Shaker design complements traditional, Craftsman, farmhouse, and transitional bathrooms while maintaining the timeless appearance of framed cabinetry. The exposed solid maple face frame also provides a comfortable place to grip the door and drawer, allowing decorative hardware to be added whenever you choose—but never requiring it.
Unlike standard kitchen base cabinets, our vanity base cabinets are built just 21 inches deep to provide more comfortable clearance around bathroom doors, toilets, tubs, and walkways while still offering practical everyday storage.
Built to Last
Built in America, the UVB18 features a solid maple face frame, solid maple Shaker door and drawer front with recessed maple plywood center panels, and a durable birch plywood cabinet box. Unlike many mass-produced cabinets, we build our cabinets using premium hardwood and furniture-grade plywood—never MDF, particleboard, or other engineered wood products—for long-term strength, durability, and dependable everyday performance.
Every drawer is built with a durable 1/2-inch plywood drawer bottom to support everyday bathroom essentials. Soft-close concealed hinges and full-extension soft-close drawer glides provide smooth, quiet operation. The unfinished maple exterior is ready for paint, stain, or clear coat, while the cabinet interior already includes a clear natural protective finish.

Finishing Your Unfinished Maple Vanity Cabinet
The unfinished maple exterior can be painted, stained, or clear coated to coordinate with your bathroom. Maple can absorb stain unevenly, so proper preparation with a quality wood conditioner or sanding sealer is recommended before staining.
Before finishing your cabinet, review our
Cabinet Finishing Guide for Unfinished Maple Cabinets.
The cabinet interior already includes a clear natural protective finish and should not be painted or stained.
Assembly & Installation
The cabinet ships Ready-to-Assemble using our pocket screw construction system for fast, accurate assembly. Pocket screw construction creates a strong cabinet while simplifying installation for both homeowners and professional installers. The door arrives pre-hung, and complete assembly instructions are included.

Professional Recommendation
We commonly recommend the UVB18 beside a vanity sink base in secondary bathrooms and guest bathrooms when the layout has room for more storage than a 15-inch cabinet provides.
If both sizes fit comfortably, choose the UVB18. The additional storage is immediately noticeable and provides greater flexibility for organizing everyday toiletries in the drawer while keeping towels, cleaning supplies, toilet paper, and grooming tools neatly stored below.
