Buying Guide
- Size and fit: Measure your sink opening, pedestal clearance, and available floor space. Look for a U-shaped cutout that matches your sink type and confirm door clearance for knee room under the cabinet.
- Storage needs: Choose a cabinet with an adjustable interior shelf if you need to reconfigure storage over time. Double doors help keep items dry and accessible.
- Material and finish: Grey finishes can range from light to dark tones. Engineered wood or CARB-certified materials help with durability and indoor air quality. Look for water-resistant finishes for bathroom use.
- Hardware and doors: Soft-closing or magnetic doors reduce wear and reduce noise. For farmhouse styles, consider cabinets with decorative handles that complement existing fixtures.
- Plumbing considerations: Verify faucet hole sizes and the openness behind the back panel to ensure easy plumbing installation, particularly for pedestal or under-sink configurations.
- Assembly and maintenance: Some vanities require assembly; check included hardware and the complexity of aligning doors and drawers. Choose surfaces that are easy to wipe down and resist moisture.
Frequently Asked Questions
- What size should a bathroom sink cabinet be for a small bathroom?
- Can under-sink cabinets fit pedestal sinks?
- Are soft-closing doors worth it for bathroom cabinets?
- Do grey bathroom cabinets require special cleaning products?
- How do I choose between a vanity with a built-in sink vs. a separate sink?
Answers: For small bathrooms, prioritize slim footprints and vertical storage; pedestal compatibility is common in under-sink cabinets with open back designs.

A vanity with a built-in sink saves overall space and plumbing work, while a separate sink may offer more flexible faucet choices.
