Played around with Zillow filters comparing bathrooms in my town in CO (lots of newer homes) with NY.
my CO town - 340 for sale, 309 have 1.5+ baths
my old NY town - 45 / 36
Tuckhahoe* NY - 9 / 6
The town from article mentioned in other thread - pricey house, 1 bath and $17k taxes
When I was little we had 1 and 1/2 baths for five-six people (my grandma often lived with us). Usually enough. When I was older, we had 2 full and 2 half. Not enough! My parents’ bathroom was considered off limits to the rest of us though we could use it in a pinch.
My family’s first home had two full and one half, but one of those full only had a giant jacuzzi tub, no shower, and the other had only a shower. Enough. That big tub was good for washing small children and lots of fun.
Current home? We are rich in bathrooms! Four full and one half for two people. We were overbathroomed even when the kids lived at home.
We live in a 1 level house with the 4 of us sharing a full bath, plus there is a toilet for emergencies in the unfinished basement. None of us spend much time in front of the mirror, and we shower quickly too.
I grew up sharing with my mom and brother.
Been totally spoiled as an adult and we’ve always had at least two bathrooms. We had 4 bathrooms in our last house and 4 1/2 in the current house. I love that when people come to visit that every bedroom has it’s own bath.
I live alone in a 5 bathroom house. I regularly use 2 of them – one upstairs and one downstairs. These 2 are essential – at least one bathroom for each floor, and one bathroom in/near my bedroom. I also find 2 more of them useful – one guest bathroom and one bathroom in a guest room. I like having a guest bathroom that is separate from my bathroom, which is often cluttered/messy and may have a different cleanliness standard. The guestroom bathroom is very useful when guests are staying in the room. I certainly would not want them to walk downstairs or in my bedroom, if they need to use the bathroom during the night. They also serve as a backup. For example, if the bathroom in my bedroom is not functioning, then I can go to the other upstairs bathroom. So I find 2 bathrooms are essential (with 2 floors), and 4 bathrooms are useful.
The 5th bathroom is completely unused, and I don’t expect this to change any time soon. I turned off the toilet in this bathroom to reduce risk of unrecognized overflow type issue. It’s only helpful for influence on home value.’
I grew up in a house with only 1 bathroom. Rather than bathrooms within bedrooms, there was a single bathroom in the hall between bedrooms. This setup worked, but was awkward at times. Fortunately, we didn’t have any issues where the one and only bathroom was broken for long periods.
S has an nyc condo with 2 bedrooms & 2 bathrooms. It’s very nice when visiting so that you don’t intrude in their master bath attached to their master bedroom. Before he had a 1 bedroom in DC with 1 bathroom. It was more challenging having 4 people share the 1 bathroom but ok for our short visits.
I really think it’s nice to have at least 1.5 baths in most homes, just so people can use the toilet as needed in case someone is occupying the other bathroom. I know it’s a luxury but one I think that has broad appeal.
We have no tubs—both our bathrooms have showers but one shower is deep enough that D can have a soak as desired. We are content and have no burning desire to remodel.
With four girls…we were not allowed to do our faces in the bathroom. We had makeup mirrors in our bedrooms, as well as our hair dryers. None of that was done on the one bathroom. We also had a schedule we had to adhere to. We each had a different departure time for school/work. So…we had a morning and evening schedule for things like showers. It worked out fine.
Our bathrooms have nowhere to sit so none of us inclined to linger at all. No one used bathroom for anything but brushing teeth, shaving, using toilet and showering.
In our home growing up with 9 people and 2 bathrooms, we never had a schedule but I can’t recall any fights over bathroom usage. We just worked things out well enough. I can’t recall anyone ever putting on makeup in either bathroom.
I wouldn’t want extra bathrooms to clean so 1.5-2 is just right.
We have 2 full baths in a one story home - a small master bath and a “main” bathroom that my two daughters share. It is a fine setup, but I wouldn’t mind having a powder room (toilet and sink) for visitors, so that I didn’t always have to wonder about the state of my girls’ bathroom when someone drops by unexpectedly.
Lol. I tell people I didn’t see the bathroom till I was 16:toilet:
A not funny at the time, but makes a great story now… someone I knew had a large family and large house under renovation. During construction, they all got norovirus. 8 people in 1 household with 1 working toilet with norovirus…. I just can’t imagine…
This is why you always need 2 toilets!!!
We have a one level home with 3.5 baths. Funny thing is, my kids use the master bathroom for taking showers because the shower is huge. It makes for easy bathroom cleaning because keeping the glass shower doors is a pain to keep nice looking. One of the full baths is connected to the guest room, so is only used when we have visitors.
We have 2 full bathrooms upstairs (one off our bedroom and a “Jack and Jill” with tub between kid bedrooms).
Downstairs we have guest bath with shower, with a handy pocket door to the den/guestroom. Alas, it has a teeny shower. There is space to expand it, and we have discussed it many times since it could make this a better “aging in place” house. Of course that is the one shower in the house in pristine conditions, so we have not yet pursued. It’s an improvement that would only be noticeable to us (especially my large husband) not future homebuyers.
Going up and down stairs may be beneficial for your health and may lengthen the time before you “need” to move into a single story home.
It seems common around here that many houses built in the 1950s were 3 bedroom, 2 bathroom… but the bathroom in the hallway was originally tub only (probably most have been remodeled by now). I guess the builders never thought that the kids using the tub would eventually want to take showers and have to go through their parents’ bedroom to use the bathroom that had the shower (often had shower but no tub).
The story goes that my parents’ farmhouse didn’t get its first real bathroom (or a washing machine) until mom got pregnant with me. 
We are lucky to have a lot of bathrooms relative to our families size but it is worth noting I have never found myself using more than one at a time😀
You definitely don’t have the skillz our ladies had… delocalized like electrons… each sufficient to occupy both bathrooms at the same time. 
Our young friends bought a fifties rambler with a luxury feature: 1/2 bath off master bedroom in addition to the full hall bath. They laughed that this is fine by them because they mostly shower at the clubs where they teach fitness classes.
I grew up in a house with a full bath downstairs and the bedrooms and a half bath upstairs. The stairs were open to the living room making it awkward to shower when my parents had guests over. There was plenty of room for a shower upstairs and my father now says he doesn’t know why he never thought to just install a shower.
Our house has 2 baths, one upstairs with the bedrooms and one downstairs that could be used to age in place if we turned the family room into a bedroom. No en suite bath, but it’s fine.
D’s house has a half bath downstairs and a full bath upstairs with the bedrooms. That makes so much more sense than the house I grew up in.
