The Roster Never Held Still
Every summer, Bravo's Hamptons docusoap swaps some of its main cast in and some out — a face or two some years, six at once in others. This ranks all ten seasons by the size of that turnover, not by who ended up staying the longest.

The 10, in order.
- #01
Six new roommates join in one summer — the biggest single-season addition the show has ever made
Six new members enter the main cast at once while several longtime housemates step away, the largest roster shake-up in the show's run. A three-part reunion, also a first, gives the overhauled group extra room to land. - #02
A lost lease forces the show's first relocation, and the cast turns over right along with the house
East Hampton denies the group's return, so the show moves to Watermill for the first time. One recurring friend gets promoted to the main cast, two newcomers join her, and three of the original cast don't come back. - #03
The weekend commute comes back in full, and so does one of the format's biggest cast reshuffles
With the classic commute format restored after the pandemic detour, three new members join the main cast while three depart for good and two more scale back to guest roles — one of the bigger turnovers the show has run. - #04
A second year in the same house still can't keep the roster from turning over
The Watermill house holds for a second summer, but three new full-time cast members join — two of them future fixtures — while four of the original housemates don't return. The setting stays put; the people don't. - #05
A lighter reshuffle than the year before, but the roster still isn't the same twice
Two new members join the main cast this year, while two others leave the show for good and two more scale back to guest appearances — a quieter turnover than the season prior, but turnover all the same. - #06
The season named for its own cast transition earns the name
Two new faces join the main cast for the show's longest order yet, while two others depart and one scales back to a guest role. A longtime cast member announces a departure only after the reunion has aired. - #07
A new Hamptons house arrives with three new faces to match
The group's first relocation since settling into Watermill years earlier brings three new members into the main cast, while the last of the show's second-season arrivals departs for good. A two-part finale closes out the reset. - #08
The lightest cast turnover the show had run up to that point
A third straight year in the Watermill house pairs with the smallest roster shake-up yet — two new faces join the main cast, and only one prior newcomer scales back. The show's longest order to date lets a settled group breathe. - #09
The quietest turnover on record arrives in the season remembered for something else entirely
Only one new face joins the main cast and only one prior member scales back — the smallest roster shift the show has had. The real disruption this year is structural: a full-time pandemic live-in replaces the usual weekend commute. - #10
The founding cast, before there was any roster to turn over
The show's debut season has no turnover to measure — every face in the house is new by definition. Ten episodes of a fixed friend group's shared Hamptons rental set the format the show has reshuffled every summer since.

cross-canon listA change of addressA show's whole identity can rest on one fixed set — a share house, a restaurant floor, a brokerage office, a boat's home waters. These are the seasons where that address changed, sometimes on purpose, sometimes because the old one fell through.similar single-show listThe anchor count set the ceilingRHOA's ceiling has tracked one variable more than any trip or twist: how many long-tenured cast members were actually in the room. This ranks all seventeen seasons by anchor count, not by drama volume.
