Get outta my bathroom, kids!
Upgrading a 2BA/1BA to Something More

The Vacuum family bought into Seward in 2019, back when a $1.25 million budget could secure a very solid two-bedroom with a balcony. At the time, they had an infant and a second child on the way — though they didn’t know it yet.
Cash was tight, but they wanted to lay down roots and secure the family for about ten years.
What they found checked the boxes: A handsome two-bedroom unit with a balcony (that their kids would never see without an accompanying grown-up and a leash for extra protection). The apartment had relatively new appliances, including a GE refrigerator and dishwasher, and Toto toilets in the bathrooms.
Despite the absence of a washer/dryer — admittedly a nice-to-have — the family submitted an offer and, following a brief negotiation, had it accepted and were under contract shortly thereafter.
A few months later they happily moved in, knowing that they would be a family of four by the end of the year.
Fast forward seven years — present-day — and the Vacuums are three-quarters of the way through that imagined timeline. Broadly speaking, their plan worked: Two bedrooms, one bathroom, no major complaints.
Well, two bedrooms, one bathroom, and the equivalent of an unceasing car alarm sounding out from the street below every 30 minutes without end.
The bathroom.
As a family of four — all mostly potty-trained — the system works. But, when Grandma and Grandpa stay over — the system is slightly compromised, especially with all of the fiber in Grandpa’s diet.
Then, one day, Mom wakes up and she’s had it. She’s tired of sharing a single bathroom with three other people. Tired of the constant interruptions. Tired of sharing with three other messy people. Tired of having a moment interrupted by a child who suddenly, urgently, needs to brush their teeth, shower , or ask a question that absolutely cannot wait.
She thinks, as only a Vacuum can: “This sucks.”
So, she takes stock, and poses a very specific question: can we fix this without leaving?
They like their home. They like their building. They like Seward Park. And they’re still operating within a budget that doesn’t make a larger purchase — or a major leap — particularly viable now.
Here’s how we thought about this:
First, we examined the viable ways to solve a one-bathroom constraint in a Seward Park two-bedroom balcony unit. We considered the tradeoffs and looked at three options, mostly avoiding the temptation to consider more expansive renovation plans.
Option 1. Do nothing.
This option is technically viable, obviously, but not particularly useful (and also very unsatisfying for a reader). Because we’re operating on a tight (but unspecified) budget, we are preserving (theoretical) capital. We avoid disruption, but avoid solving the problem.
The only real value in this option is as a benchmark: if the cost, disruption, or logistics of renovation don’t make sense, the family may ultimately decide to wait, sell, and upgrade later — either within Seward or elsewhere in the neighborhood. (That’s why it’s here.)
Option 2. Add a half bathroom.
This is the most targeted solution. If the core issue is toilet access — particularly during peak usage times or when guests are present — a half bath can materially relieve pressure on the system. It doesn’t solve for showering capacity, but in many Seward layouts, the existing full bathroom is already accessible without passing through a bedroom, so that’s less of a concern.
While this won’t be an inexpensive venture, it will be less costly and less disruptive than Option 3, forthcoming.
Here is an example of the 2BR/1.5BA balcony unit:
Option 3. Add a full bathroom.
Here, the family has choices within the choice. One approach is to create an ensuite bathroom from the primary bedroom, giving the Vacuum parents a private bathroom and removing them from the daily competition for space. Another is to simply add a second full bath accessible from the common area, maximizing utility for the entire household and for guests.
This option delivers the greatest functional improvement and the strongest resale impact. A true two-bathroom home operates very differently than a one-and-a-half. It changes how mornings work. It changes how guests are hosted. It changes how the apartment is perceived in the market.
But, this is the most expensive path. It requires more extensive planning, more approvals, and typically more invasive construction — potentially including moving walls, reconfiguring layouts, and extending plumbing lines in more meaningful ways. The timeline is longer. The disruption is greater. Temporary relocation — whether for a few weeks or a couple of months — becomes more likely.
That said, there’s a strategic argument here. Once you’re opening walls and running new plumbing, much of the heavy lift is already underway. The incremental step from a half bath to a full bath may be meaningful, but it’s not starting from zero. If the budget can support it, this is often the moment to “do it right” rather than “do it twice.” (The same goes for adding a washer-dryer into the mix.)
Here are a few examples of the 2BR/2BA balcony units:
383 Grand Street #M304 (with ensuite)
417 Grand Street #D504 (with ensuite)
413 Grand Street #F1706 (with ensuite)
Ultimately, it comes down to priorities. For the Vacuums, they just don’t want to get totally cleaned out.
