Why Your Bathroom Vanity Matters

Your vanity is the functional centerpiece of your bathroom — where design meets utility. The right choice affects:

• Storage capacity
• Sink and plumbing layout
• Lighting and mirror placement
• Overall resale value

“A well-sized vanity not only enhances usability but anchors the design,” says Jenna Frye, a certified bathroom designer in Portland.

Step 1: Measure Before You Shop

Choosing the right vanity starts with accurate measurements:

Key Measurement	What to Measure
Width	Side to side space available
Depth	From the wall out — don’t block entry or toilet
Height	Standard is 32"–36", but comfort-height is rising
Plumbing Rough-Ins	Location of drain and water lines
Clearance Requirements	Leave 18"+ in front for accessibility

Pro Tip: Use painter’s tape to mark the vanity’s footprint before buying.

Step 2: Understand Vanity Types

Type	Best For	Pros	Cons
Freestanding	Traditional bathrooms	Easy to install, classic styles	May show plumbing underneath
Wall-Mounted (Floating)	Modern, small spaces	Saves floor space, sleek look	Requires strong wall support
Corner Vanities	Tight layouts	Utilizes awkward space	Limited countertop and storage
Custom Vanities	Luxury remodels	Tailored sizing and finishes	Expensive, longer lead time

Step 3: Plumbing Considerations

If you're replacing a like-for-like vanity, plumbing is easy. But for new layouts:

• Moving the sink or drain line? Expect $500–$1,500+ in extra costs.
• Wall-mounted vanities often require rerouting pipes into the wall.
• Don’t forget to shut off water and cap lines during install.

“Many homeowners underestimate plumbing complexity,” says licensed plumber Joel Menendez. “It’s where DIY goes wrong fastest.”
