I’m very happy we have two sinks. I find we are actually often needing them same time and I prefer it.

Size matters...if there is room ...2 sinks are always preferable...if two people use the bath for sure...for resale one sink is a negative..

Two sinks:

1. More practical if you ever have two people sharing the bathroom at the same time.

2. A little less vanity space to pile crap on, which I view as a plus.

3. Easier to keep the sink area organized the way you prefer it if you don't have to share the space.

4. Preferable when selling your house, as many potential buyers are working couples getting ready at the same time. (In fact, if I were to buy a house with a one sink master bath, that would be the first thing I'd be remodeling...and most buyers don't want to start a purchase by thinking about what they want/need to immediately change.)

5. One person in most couples -- usually the woman -- is typically neater using the sink area, so always cleaning up after a sloppy spouse is not a happy thing...unless you don't mind facing toothpaste spit and shaving detritus first thing in the morning.

Yes.....personal choice. Other things to consider

-For resale, most prefer a double sink.

-If only one sink, how clean is your partner? A slob that you must clean up after or use a dirty sink?

Sink you already have enough storage, I would go for 2 sinks for sure. Why do you need a lot of counter space? I recommend keeping toiletries in basket.....take them out for daily use and put them away when finished.

I do trough sinks so its a win win - two faucets- larger sink area than single sink but not as much of a space hog as two separate sinks so there is more counter space

Two sinks only if you have room for the sinks and generous surface space. Otherwise, one sink. I haven't found one sink to be a resale issue if there is plenty of surface area around the sink. I have found that if you squeeze in two sinks it won't overcome the lack of storage or surface area. Jan Moyer said it best in her post above.

We have enough room for 2 sinks but are going with one. More counter space, less plumbing, one less sink to clean, we rarely get ready at the same time. 2 sinks would be a waste for us

We have never had 2 sinks and I don’t seem to remember a time when we thought we needed 2 .

Two for sure. Even if one sink works for you personally, people like me will pass on buying a home with one sink master bath. My husband and I get ready for work at the same time every morning and hated the times when we lived in places with one shared sink.

One sink, centered. A custom vanity allows you to minimize the size of the cavity which contains the plumbing. With proper planning it's possible to have a drawer under the sink cavity, mine is deep enough to hold TP rolls.

We've been married 30 years this summer, and I can't remember a single sink ever being an issue for us -- and, yes, for most of our married life we both worked the same hours /left the house at the same time.

-For resale, most prefer a double sink.

Disagree. If this site is any indicator, we consistently seem to be split on this topic. Personally, a double sink would be a pretty big negative for me -- I won't say I wouldn't buy a house with two sinks, but it would be a pretty big strike against the house; if the house had two sinks AND a toilet-in-a-closet, it'd be an absolute no.

-If only one sink, how clean is your partner? A slob that you must clean up after or use a dirty sink?

I've never understood this argument. If you're a neat person, you're going to be just as bothered by that second dirty sink -- even if it is a few feet away -- the difference is that you'll end up cleaning two sinks.

Two sinks only if you have room for the sinks and generous surface space. Otherwise, one sink. I haven't found one sink to be a resale issue if there is plenty of surface area around the sink. I have found that if you squeeze in two sinks it won't overcome the lack of storage or surface area.

This is a reasonable, middle-of-the-road post. Never a second sink at the expense of storage.

One sink, centered.

Yes to centered. That's one of the problems caused by duplicate sinks; they're often pushed over so far that one spouse is touching the wall.

I never understand how anyone finds it necessary to spend so much time and space telling so many people how wrong they are..isn it enough to just add your ideas?..

I'm a one sink fan for sure! Definitely prefer countertop room and storage. Plus, truth be told, I don't enjoy cleaning ONE sink so why on earth would I want a 2nd one? lol OH - he's supposed to clean his OWN sink, huh? ROFL

At the end of the day I think it's a matter of assessing your needs and what your personal preferences are.

I've been living with a double sink in a 60' vanity for 25+ years and the second sink hardly gets used. There are 4 of us living here now but we were once 5 and for some reason we rarely needed to use the bathroom sink at the same time. Whenever one of us did, we would just wait our turn or use the sink in the powder room on the main floor.

Regardless, I've hated the double sink from the get go. In a 60' vanity, there's very little usable counter space and I've always found it cumbersome trying to get close up to the mirror to put on eye make-up for example. Also the sinks use up under counter space that could otherwise be usable with only one sink. Instead of one row of drawers and 4 doors, you'll get and extra row of drawers which is way more practical.

If you are doing a 72" vanity it might be another story.

Yes, 60" is tight. We have 80" and it's more than enough room. If you install pedestal sinks, there is even more counter area. And the downside of too much counter area is all the crap that accumulates. I like a vanity that doesn't look like a clearance sale at the drugstore:

The key to less counter clutter is handy easy access storage space..and maybe a little training if you have to share the space with a schlub...

Having 2 sinks would not sell me on the house. What I would dearly love here, is more storage and a shower in the bathroom downstairs. Never had the occasion to need 2 sinks. I don’t WANT to share a bathroom with anyone in the universe.

Entirely dependent on: (a) how much space you have in the bathroom, (b) whether you both need to get ready in the morning at the same time, and (c) how much "real estate" you each need for storage of your stuff.

If you have the room, I think two sinks in a master bath are a must.

Sabrina said it best, like the answer to so many questions, is it depends. When our house was built, in the early 20th century, just having a master bath was the height of luxury! When we moved into the home, the master bathroom measured 5' x 5' and had a small corner sink, a toilet, and a 24" x 24" shower. We took turns using it to get ready for work in the morning; it was far from adequate. In 2009 we added a 10' x 10' space to include a large shower, enclosed toilet room (with a window), a closet, and a 10' long vanity wall. We each have a 42" vanity (with lots of storage)and a drop down space in the center with storage for towels. We also have built-in medicine cabinets for more storage, so there is not a lot of "stuff" on the counter tops. To say that this is preferable is an understatement! However, it would have been a challenge to fit double sinks in a smaller bathroom. You need to figure out your space, and what works for YOU and your family; there is no one right answer.

Yes, it is a combination of what you prefer, available space, budget and resale.

My vote is for 2 sinks.

If you use a prefab vanity/sink combination, storage and utility don’t mix well. I have 2 pedestal sinks but custom made drawer units flanking them. Open the drawers in a prefab vanity—they are woefully short on space. To avoid having counter space completely cluttered with products, maximize your storage. If clutter doesn’t bother you and you want/ need to brush your teeth simultaneously, then sacrifice storage for 2 sinks. There are ways to get what you need for how you live but you need to be honest about how you live. The 50-50 split on this reflects the different priorities. Also, I can’t see the original post on whether this was exclusively for a MB, but if this is a family bathroom, that may make a difference too.

Having two sinks doesn't need to come at the cost of storage -- you need to pick a vanity where the plumbing enters the wall a bit higher. Mine has a cupboard and two drawers for each, but I've used vanities that have a cupboard and 3 drawers for each, with no cutouts!

Pair this with a good medicine cabinet mirror, and you don't need counter space for anything but splashing. (ok, maybe a toothbrush holder)

Nicer but what do those drawers actually hold? In my experience, not much and are not utilitarian. My unit is 36 wide. Top drawer is shallow for makeup and what not. Next two drawers and deep and have built in power so I never have a hair dryer on my counter plugged in. Again, all depends on how you live but I want to open my drawer and see everything I might need instead of having like items spread across 3 drawers or in some bin you have to rummage through or whatever. Prefab vanities look nicer than they are when you want to hide stuff! That is my experience, anyway. Those drawers in that picture are how wide inside? Maybe 6 inches interior? 8 at the most? Not enough for me. :)
