Why 48 Inches Became the Single-Sink Go-To
The 48-inch single-sink bathroom vanity is the most specified width in primary bathroom renovations for a reason: it fits the body. At 48 inches, you have 18 to 20 inches of sink bowl, plus meaningful counter space on both sides — enough for a person using the sink to have product and toiletry space without feeling cramped, and enough cabinet width to run a two-drawer column on each flank of the basin. It also fits in a standard bathroom alcove without requiring a dedicated large space.
Single-sink bathroom vanities at 48 inches are available at Yala Vanity in wall-mounted and freestanding configurations from Vanderloc (custom American-made), Vinnova, and other premium brands. Free shipping across the contiguous USA on all orders.
Who a 48-Inch Vanity Works Best For
The 48-inch is the right size for a single-person primary bathroom, a large guest bath, or a secondary bath where counter space matters more than a second sink. For a couple sharing a primary bath, the 48-inch works if the bathroom routine is non-simultaneous — morning overlap is manageable for two people but tight, and the counter space conversation about who owns which half of the sink area starts immediately. For couples who both use the bathroom at the same time in the morning, look at 60 or 72-inch double-sink options instead (see our double sink guide).
Configuration Options at 48 Inches
A 48-inch vanity is wide enough to run meaningful drawer storage on either side of the basin. The better-designed pieces at this width use two to three drawer columns flanking the sink rather than a single door-with-shelf on each side. Vanderloc Ventura and Alexandra configurations at 48 inches prioritize drawer access throughout — six or more drawers is achievable at this width and substantially improves daily storage usability over a comparable piece with doors.
At 48 inches, a floating (wall-mounted) configuration has unobstructed under-sink space — no P-trap inside the cabinet — allowing full-depth drawer extension below the basin. Freestanding options at this width need to route plumbing through or around the cabinet interior, which affects the lowest drawer or shelf configuration. Worth checking the interior diagram before ordering.
Choosing a Finish at 48 Inches
At 48 inches, the cabinet face is wide enough for the finish to read clearly in the room. A single door in a complex grain pattern can read as busy; a four-drawer column in Rift White Oak reads as considered and intentional. The Vanderloc Rift White Oak at 48 inches, with the linear grain running vertically across the drawer faces, is one of the cleaner applications of that finish at this width. Painted finishes at 48 inches read as more traditional or transitional depending on the profile — Alexandra with paint is transitional, Ventura with paint is contemporary.

Frequently Asked Questions
- Is 48 inches wide enough for two people to share a bathroom vanity?
- Technically yes, but the experience is tight. Two people using a 48-inch single-sink simultaneously is a compromise — there is one sink and roughly 14-15 inches of counter on each side. For morning routines that overlap significantly, a 60 or 72-inch double-sink is a better investment. For asynchronous routines, a 48-inch single is workable.
- What is the depth of a standard 48-inch bathroom vanity?
- Standard depth is 21 to 22 inches, which accommodates a standard undermount basin and leaves a small counter reveal at the front. Some deeper custom options run 24 inches for more interior storage depth. Confirm depth when ordering — it affects how far the countertop edge extends into the bathroom floor plan.
- Are 48-inch vanities available in floating (wall-mounted) configuration?
- Yes. Vanderloc, Vinnova, and other brands Yala Vanity carries offer 48-inch wall-mounted configurations. Installation requires locating studs or installing a plywood backer — standard for floating vanity installation at any width.
- Can I get a 48-inch Vanderloc vanity in a custom finish?
- Vanderloc offers Rift White Oak and painted finish options at 48 inches (and all other widths). Contact the Yala Vanity team to discuss current finish availability and which option fits your bathroom palette best.
