Bathroom Vanity Storage: Start With the Plumbing

Start bathroom vanity planning by locating the sink, drain and supply lines, then design storage around the space that remains. A drawing of the cabinet interior can help you see where a drawer might meet pipes or where frequently used products could fit. Have plumbing conditions assessed by an appropriate professional rather than treating a cabinet sketch as instructions for changing pipes.

Map what the vanity must hold

List the items used at the sink each day, such as toothbrushes, skincare products, hair tools or shaving supplies. Separate them from occasional items, spare products and cleaning supplies, which may belong elsewhere. Measure taller bottles and any equipment that needs to stand upright, and consider how many people need access at busy times.

Then note the fixed features inside the vanity: sink bowl, drain, supply lines and any other existing components. The space beneath a sink is rarely one uninterrupted box, so ask the designer to account for the actual configuration. A shallow drawer, a smaller compartment or storage beside the plumbing may be more useful than a full-width drawer that cannot open as intended.

Coordinate drawers and doors with access

Test how drawers will move in relation to the sink, cabinet doors and the person standing at the vanity. A drawer that appears generous in a plan may be less useful if the plumbing reduces its depth or if its contents are awkward to reach. Ask what stays accessible for routine inspection and maintenance, and confirm the arrangement with the relevant plumbing professional.

Consider whether open shelves, drawers or doors best suit the contents. Drawers can make small items easier to sort, while a door-front cabinet may accommodate taller objects depending on the layout. Neither solution is automatically better; the choice depends on the plumbing map, item sizes and how the household uses the room.

Coordinate the mirror and finish

Decide where the mirror, lighting and vanity top sit in relation to the cabinet before finalizing proportions. A mirror with storage may change how much wall area is available, while a simple mirror can keep the visual composition quieter. Treat electrical planning as a separate coordination item and involve qualified trades where the project requires electrical work.

Bathrooms experience moisture, but that does not make every cabinet finish suitable for every location. Ask the supplier for the specific finish and care instructions, including any guidance about moisture exposure, ventilation and prompt attention to spills. Avoid relying on broad labels such as “bathroom safe” without product-specific information.

A hypothetical shared vanity

Imagine two adults sharing a compact bathroom and keeping different daily products at the sink. The sink plumbing takes up the middle of the vanity, while a hair tool and several tall bottles need defined storage. They could separate each person’s everyday items into accessible zones, reserve the area around the plumbing for suitable contents and move infrequent supplies to a separate cabinet.

The layout should be checked against the actual sink and pipe arrangement before cabinetry is finalized. That step helps the design reflect the room as it exists, rather than assuming the inside of a vanity is empty.

Vanity planning checklist

• Locate the sink and document existing plumbing conditions.
• Inventory daily, occasional and bulky items by size.
• Check drawer movement and access around pipes.
• Coordinate mirror and lighting decisions early.
• Confirm finish care and moisture guidance with the supplier.
