Bathroom vanities act as compact worktops housing the basin while offering a handy surface for bits like toothbrush holders, soap pumps, or electric razors. Typically, they stand between 30-34 inches tall, though "comfort height" options at 36 inches cater to loftier users.
Let’s unpack what dictates the ideal vanity height for your washroom.

Table of content
Standard Sizes
Most vanities range from 30-36 inches tall. The 30-34 inch bracket counts as standard, while 34-36 inch versions suit taller folk.
Depth-wise, they’ll usually span 17-24 inches. Width varies most dramatically – from dinky 24-inch single-sink units to sprawling 72-inch doubles. Single basins generally occupy 24-48 inches, while doubles stretch 60-72 inches. Always measure your space *and* account for door/drawer clearance before committing.

Key Considerations
Nailing the right height involves weighing up:
1. User Heights
Factor in everyone who’ll regularly use it – from sprogs to visiting nan. While 34 inches works as a middle ground, prioritise your main users:
- 30-32 inches: Better for shorter folk
- 36 inches: Ideal if your clan’s mostly over 6ft
2. Existing Setup
Swapping sizes? Mind the plumbing! Significantly altering height/depth might mean rejigging pipes and electrics – a job for pros unless you’re handy with a blowtorch. Sticking to similar dimensions avoids costly adjustments.
3. Space Planning
Your new unit mustn’t block bog access or door swings. Remember:
- Allow elbow room for opening cupboards
- Position mirrors 5-10 inches above vanity (eye-level for average users)

Sink Types
Most basins play nice with standard heights, but exceptions exist:
- Vessel sinks perch atop the unit, adding up to 6 inches – opt for 30-32 inch vanities to compensate
- Undermount sinks tuck beneath the counter – consider taller vanities for comfort
- Tabletop basins (chunky vessel-style) similarly raise height – stick to 30-32 inch bases
FAQs
Is 36 inches too tall?
Depends who’s using it. Grand for 6-footers, awkward for kids. Compromise at 34 inches if households mixed.
Mirror height?
5-10 inches above vanity usually hits the sweet spot.
Top tip: Grab a tape measure and mock up different heights using cardboard – you’ll soon suss what *feels* right when leaning in to wash up. After all, there’s nowt worse than a backache from hunching over your basin!
