30-Inch Grey Bathroom Vanity Ideas: Five small-space design inspirations for a 30-inch grey bathroom vanity, from a designer who’s made plenty of rookie mistakes

I once installed a vanity mirror upside down because I misread the template — the clients were surprisingly calm, and I learned to always double-check templates before drilling. That little fiasco taught me an important truth: small bathrooms are where creativity and attention to detail matter most. Small spaces can inspire big ideas, and a 30 inch grey bathroom vanity is a perfect starting point.

1. Floating 30-inch grey vanity for visual space

I love floating vanities because they immediately free up floor sightlines and make tiny bathrooms feel airier. A 30-inch grey wall-mounted unit keeps storage tucked in but visually light. The advantage is cleaner lines and easier floor cleaning; the challenge can be ensuring solid wall anchors — I always recommend reinforced studs or a mounting rail.

2. Integrated open shelving with a 30" grey vanity

Mixing closed drawers with a slim open shelf under a 30" grey vanity gives both concealment and display. You get hidden space for toiletries and an accessible spot for towels or a plant. It’s stylish and practical, though you’ll need to keep the open shelf tidy to avoid cluttered looks — I tell clients to treat it like a tiny vignette.

3. Contrasting countertop materials

Pairing a grey vanity with a warm wood or bright marble countertop creates deliberate contrast that elevates the entire room. A 30-inch vanity doesn’t limit material choices; quartz or a thin slab keeps weight down while achieving a luxe look. Budget-wise, quartz hits a sweet spot — durable and mid-range — but heavier natural stone may require extra support.

4. Smart storage inside a compact 30-inch cabinet

Don’t underestimate internal organization: pull-out trays, vertical dividers, and tilt-out bins make a 30" grey vanity punch above its weight. I once designed a tiny urban apartment bathroom where clever inserts turned a narrow cabinet into an efficient grooming station. The small downside is the added cost for custom inserts, but they pay off in daily convenience.

5. Coordinate fixtures and hardware

Matching matte black or brushed brass hardware with a grey vanity creates a cohesive, modern look. For a 30-inch piece, the right faucet scale matters — single-hole or center-set faucets work best. The trick is balance: too-large fixtures overwhelm the cabinet, while tiny ones can look clipped. I advise clients to test mockups before committing.
