48 Inch Bathroom Vanities
A 48 inch vanity is the sweet spot width for most primary and guest bathrooms — wide enough to offer generous storage and a roomy countertop, but compact enough to leave comfortable clearance for the door swing, toilet, and shower entry in a standard 5x8 or 5x10 bathroom layout.
At 48 inches, you get a real choice between a single-sink layout (with a spacious offset counter area for toiletries and decor) or a 48 inch double sink vanity with two compact basins — the narrowest width where a true his-and-hers configuration is practical. Most models ship with a matching top and pre-drilled faucet holes, and drawer-forward cabinet layouts at this width typically fit 3-4 functional drawers alongside a plumbing cabinet.

Frequently Asked Questions
Should I get a single or double sink vanity at 48 inches?
For most households, a single sink is the smarter choice at 48 inches. A double-sink 48 leaves each basin with only about 20-22 inches of counter, which feels cramped for daily use. Choose a double only if simultaneous morning use is a must-have. A single-sink 48 offers a full countertop landing zone on one side — ideal for makeup, electric toothbrush chargers, and decor.
What size mirror goes over a 48 inch vanity?
A mirror should be 2-4 inches narrower than the vanity on each side, so plan for a 40-44 inch mirror over a 48 inch vanity. For double-sink 48s, use two mirrors approximately 20-22 inches wide, centered over each basin. Hang the mirror 5-10 inches above the backsplash, and keep the top edge at least 6 inches below any wall sconce.
What size bathroom do I need for a 48 inch vanity?
A 48 inch vanity works in bathrooms of roughly 40 square feet or larger — typically 5x8 or bigger. You'll want at least 30 inches of clear floor space in front of the vanity and 15 inches from its centerline to any adjacent fixture. In tighter layouts, step down to a 36 inch model to preserve walking room.
How many faucets and drain holes come pre-drilled?
A 48 inch single-sink top is typically pre-drilled for a single-hole or 8-inch widespread faucet at the center. A 48 inch double-sink top comes with two faucet cutouts, one over each basin. Always confirm the drilling pattern matches your chosen faucet before ordering — some tops offer 4-inch centerset or single-hole configurations instead of widespread.
Does a 48 inch vanity add resale value?
Yes — 48 inches is the most-listed vanity width in real estate photos for mid-sized primary and hall baths, so it reads as "properly proportioned" to buyers. It avoids looking undersized (common with 30-36 inch vanities in larger rooms) without the oversized footprint of a 60 or 72. Neutral finishes like white shaker or gray oak broaden resale appeal at this width.
