10 Brilliant Two Sink Bathroom Ideas: My Favorite Ways to Design a Double Vanity Bathroom without Wasting Space

A few years ago, I had a client who insisted their tiny en suite needed two sinks… plus a makeup counter, plus storage for a hundred skincare bottles. At first, I thought, “This is impossible.” But that project taught me that when space is tight, creativity flows faster. Small bathrooms can absolutely pull off a stylish and functional double vanity — if you get the details right. Today, I’m sharing my 10 favorite two sink bathroom ideas, drawn straight from real projects I’ve designed.

1. Floating Double Vanity

I love how a floating vanity makes a bathroom feel bigger by exposing more floor. Pair it with under-cabinet lighting, and it becomes a soft night light too. The only challenge? You’ll need sturdy wall support and plumbing clearance, which a well-planned bathroom layout can help visualize before construction.

2. Slimline Countertop Design

In a small bathroom, I often use slimmer counters so two sinks fit without eating all the space. Quartz and solid surface materials work beautifully here because they remain strong even at reduced depth. Keep faucet fixtures compact to maintain elbow room.

3. Integrated Storage Towers

Adding a narrow vertical storage tower between two sinks is a lifesaver for couples who don’t want to mix toothbrushes. It can hide outlets inside for charging, and breaks up the counter visually, giving each person a defined zone.

4. Offset Sinks for More Surface Space

Instead of centering both sinks, I sometimes offset them toward the ends of the vanity, leaving more shared counter in the middle. It’s a clever way to gain usable space for makeup trays or decorative touches.

5. Corner Double Vanity

If you’re working with an awkward layout, two sinks can actually meet at a right angle. It’s unconventional, but with the right custom cabinetry and a clear floor plan drawing, it can free up room elsewhere for a bigger shower or extra storage.

6. Vessel Sinks for a Luxe Look

Vessel sinks sit on top of the counter, so you can often fit a shallower vanity cabinet underneath. They bring strong visual character, but do watch faucet height and splash-back potential.

7. Mirrored Wall with Dual Lighting

Mirroring the entire vanity wall visually doubles the space. Combine that with sconces on each side of the mirrors for even, flattering light — which makes morning routines feel a little less rushed.

8. Two Pedestal Sinks with a Shared Shelf

Perfect for bathrooms without space for a full vanity, two pedestals can still feel connected with a shared shelf or counter bridging them. This keeps things airy while still providing a spot for soap and essentials.

9. Recessed Medicine Cabinets

I’ve had clients shocked at the storage you can hide inside a wall. Recessed cabinets over each sink mean fewer countertop clutter fights, and if you choose mirrored doors, they contribute to that light, airy feel.

10. Custom Double Vanity for Awkward Walls

Not every bathroom is a perfect rectangle. That’s where a custom build shines — you can shape it around plumbing quirks or niches. Using a virtual bathroom planner first helps ensure the measurements are perfect, avoiding costly on-site surprises.
