What ten years of sales say in Rosemère
- The 2-bathroom house rose fastest in Rosemère: +127%, against +121% for 1 bathroom, +124% for 3 or more bathrooms. That is the case in 22 of 50 cities: the standard family format, a full bathroom upstairs and a second one downstairs, is the one in shortest supply.
- The second-bathroom premium is stable: +19% in 2016, +23% in 2026 ($155,500 between the two medians).
- The 3-plus-bathroom house cost more than the 2-bathroom house every year with enough sales: in Rosemère, the third bathroom belongs to the large recent house with an ensuite, not to converted basements.
- Share of 1-bathroom houses in sales: 29% in 2016, 25% in 2026 (over ten years: 1 bathroom 21%, 2 bathrooms 56%, 3 or more 22%).

Is the second bathroom worth paying for in Rosemère?
In Rosemère, the second bathroom is a different product: $155,500 more at the median (+23%). At that price you are not buying a bathroom, you are changing house: newer, larger, a full bathroom upstairs and a second one downstairs, often a garage. For a family, the cheaper route is often the 1-bathroom house with a basement where one can be added; for the seller of a 2-bathroom house, it is the argument to lead with. The third bathroom costs $354,500 (+42%), on 21 sales of houses with 3 or more bathrooms from January to September 2026.
How to read these numbers
One median per year and per bathroom count, for all of Rosemère. The count comes from the Centris listing (full bathrooms, powder rooms apart) and says nothing about their condition. The gap between two classes measures what the market pays for the typical house of each class, not what one more bathroom would add to yours. Years with fewer than 10 sales are not published. A broker evaluation settles it for one specific house.
