Double Vanity Ideas: 5 Small-Bathroom Solutions: Clever double vanity layouts and tips to fit two sinks into compact bathrooms without losing style

I once designed a tiny bathroom where the homeowner insisted on two sinks so they could “not fight over toothpaste.” I nearly put the sinks on opposite walls until a clever layout saved both space and marriage. Small spaces force creativity — and that’s my favorite kind of challenge.

1. Narrow Floating Double Vanity

Floating vanities make a small bathroom feel airier because you can see more floor. I often specify a narrow floating double vanity with shallow basins (about 12–14 inches deep) to keep circulation clear. The upside is modern looks and easier cleaning underneath; the tradeoff is limited storage depth, so I pair it with vertical storage or recessed medicine cabinets.

2. Split-Level Countertops

For couples who want personal zones, split-level countertops create the illusion of separate vanities while remaining one continuous unit. I used this in a recent project with two small bowls set into a 60-inch counter — it preserved counter space while giving each user their own area. It’s stylish and practical, but plumbing can be slightly more complex.

3. Corner Double Vanity

Corner vanities are a sneaky way to fit two sinks where a straight run won’t work. I once turned an awkward corner into a functional duo sink station using compact round basins and a triangular countertop. The benefit is maximal floor space elsewhere; the downside is you must plan mirror and lighting carefully for each user.

4. Undermount Sinks with Shared Countertop

A shared countertop with two undermount sinks keeps things streamlined. Choose a light-colored stone or engineered surface to visually expand the room. I recommend installing drawers under each sink for personal items — it avoids the “whose toothbrush is that?” dilemma. This option balances storage and simplicity, though material costs can be higher if you pick natural stone.

5. Recessed Cabinets and Pocket Doors

If circulation is tight, reclaim wall space by recessing cabinets or using a pocket door to access the bathroom. I worked on a renovation where moving the door and adding recessed drawers allowed a 48-inch double sink run to fit comfortably. It’s brilliant for tight footprints, but plan structural work and costs ahead.

If you want to quickly test layouts before demolition, try an online room planner to visualize different double vanity placements in your exact floor plan.

Tips 1:

General tips: pick shallow basins, use floating units to open sightlines, prioritize vertical storage, and unify finishes to make the room feel larger. Small-budget wins include swapping old doors for pocket doors and choosing multi-functional fixtures. For a realistic 3D preview, experimenting with a 3D floor planner saved one of my clients time and costly rework by proving sightlines and clearances in advance.

Q6: Can I DIY install a double vanity? A6: Basic installations are DIY-able if you have plumbing experience, but moving drains or walls should be left to professionals to meet codes.

Q7: Where can I find layout tools to try ideas? A7: Many designers use online floor planners to test spacing and sightlines; a reputable example is offered by universities and design software providers (refer to design software documentation for specifics).

Q8: Any authoritative source on bathroom clearances? A8: For precise code requirements and minimum clearances, consult the International Residential Code (IRC) and local building codes (see IRC plumbing and fixture clearance sections).
