This question comes up in almost every primary bathroom consultation I do: is a double vanity worth it, or is a single vanity the smarter call? The honest answer depends less on square footage than most people assume, and more on how mornings actually go in your house.
The Case for a Double Sink Vanity
If two people are getting ready at the same time most mornings, a double vanity removes the daily bottleneck. On a recent project of ours on Westmoreland Way, we built a dual-sink vanity into the primary bathroom specifically because the clients had two very different morning routines and were tired of waiting on each other. It’s one of the upgrades clients tell me they notice every single day, not just when guests visit.

The Case for a Single Vanity
A single vanity isn’t a downgrade in a smaller bathroom, it can mean a bigger mirror, more counter space per person, and a less cramped feel overall. For a secondary or guest bathroom that isn’t used by two people simultaneously, a single vanity is almost always the better use of the footprint. In fact, that same Westmoreland Way home is a good example of this decision working both ways in one house: the primary bathroom got the double vanity above, while a secondary bathroom kept a single vanity with a bigger mirror and a bit more breathing room on the counter.

How Much Space Do You Actually Need?
As a rule of thumb, I recommend at least 60 inches of vanity width before considering a double sink comfortably below that, two sinks tend to feel cramped rather than convenient. If your bathroom is tighter than that, a single vanity with a slightly wider single sink is usually the better tradeoff.
My Honest Recommendation
For a shared primary bathroom used by two people on similar schedules, a double vanity is almost always worth the investment if the space allows it. For a guest bath, kids’ bathroom used one at a time, or any bathroom under about five feet of wall space, I’d put the budget toward a nicer single vanity instead.

FAQ Section (PAA-sourced, answer-first for AEO)
Q: Do I need a double vanity in my bathroom?
A: A double vanity makes the most sense if two people use the bathroom at the same time most mornings. If the bathroom is used by one person at a time, a single vanity with more counter space is usually the better choice.
Q: How much space do you need for a double vanity?
A: At least 60 inches of vanity width is generally recommended for a comfortable double vanity. Below that, two sinks tend to feel cramped rather than convenient, and a single vanity is usually the better fit.
Q: Does a double vanity add resale value?
A: In a primary bathroom, a double vanity is a feature many buyers look for and can support resale value. In a smaller secondary bathroom, it’s less impactful and a well-designed single vanity often serves the space better.
