Picking the right vanity size can make or break your bathroom renovation. Too small and you're stuck with no counter space. Too big, and your bathroom feels cramped. Here's how to figure out exactly what size you need.
Measure Your Space First
Before you fall in love with any vanity, grab a tape measure. You need three measurements: the width of the space where your vanity will go, the depth (how far it sticks out from the wall), and the height from the floor to where you want the countertop.
Don't forget about doors. Measure how much clearance you have when the bathroom door swings open. Your vanity shouldn't block the door or make it awkward to walk into the room. The same goes if you have a shower door nearby.
Standard Vanity Sizes
Most vanities come in standard widths: 24", 30", 36", 48", 60", and 72". Single-sink vanities typically range from 24 to 48 inches wide, while double-sink options start at 60 inches and go up from there.
For depth, standard vanities are usually 21 inches, though you can find shallow options at 18 inches if you're working with a tight space. Height typically sits around 32 to 36 inches, with 36 inches being the modern standard (older homes often have 32-inch vanities).
How Much Space Do You Actually Need?
Here's the thing: you want at least 4 inches of clearance on each side of your vanity if possible. This gives you elbow room and makes the space feel less tight. If you're installing near a toilet, keep at least 15 inches of space between the two.
For walkways, aim for a minimum of 30 inches of clear floor space in front of the vanity. This gives you enough room to stand comfortably and open drawers without doing an awkward shuffle.
Single Sink vs. Double Sink
If you share a bathroom with someone else, a double vanity might seem like the obvious choice. But you need at least 60 inches of width to make it work properly. Anything smaller and you'll both be fighting for space.
Single-sink vanities work great for guest bathrooms, powder rooms, and smaller master baths. A 36-inch or 48-inch single vanity often gives you more storage and counter space than cramming in a double sink that's too small.
Consider Your Storage Needs
Think about what you actually need to store. If you're drowning in hair products, skincare, and towels, look for vanities with multiple drawers like the Granada 3 Drawer Valenti. Drawers beat cabinets for organization since you can see everything without digging around.
The Runway Vanity offers a sleek look if you prefer open shelving or want to display decorative baskets underneath.
Don't Forget About Plumbing
Your existing plumbing location matters. Moving plumbing is expensive and complicated. Measure where your water lines and drains currently sit, and try to find a vanity that works with that setup. Most vanities have flexible plumbing placement, but it's worth checking before you buy.
The Bottom Line
The right vanity size depends on your bathroom dimensions, how many people use the space, and what you need to store. Measure carefully, leave enough clearance around the vanity, and pick a size that fits your daily routine.
