Closed sales on Centris from 2016 to September 2026: 394 1-bathroom houses, 891 with 2 bathrooms and 333 with 3 or more. A year with fewer than 10 sales in a class is left blank (n/a). When a year has few sales, its median swings a lot: read the trend, not a single year.
What ten years of sales say in Saint-Lambert
- The house with 3 or more bathrooms rose fastest in Saint-Lambert: +175%, against +112% for 1 bathroom, +98% for 2 bathrooms. That is the case in 7 of 50 cities: the large recent house, with a bathroom on every floor, became the scarce product.
- The second bathroom costs less than it did: +19% in 2016, +12% in 2026 ($115,000). The 1-bathroom house caught up: a sign that the entry level has become scarce, and that buyers take it on as a renovation.
- The 3-plus-bathroom house cost more than the 2-bathroom house every year with enough sales: in Saint-Lambert, 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, 26% in 2026 (over ten years: 1 bathroom 24%, 2 bathrooms 55%, 3 or more 21%).
- 2019 to 2022, the three rock-bottom-rate years: 1 bathroom +47%, 2 bathrooms +42%, 3 or more bathrooms +71%.
- 2026 (January to September) versus 2025: 1 bathroom +13.7% ($857,500 to $975,000), 2 bathrooms -9.2% ($1,200,000 to $1,090,000), 3 or more bathrooms +17.6% ($1,678,500 to $1,973,750).
- Annual peaks: 1 bathroom $975,000 in 2026, 2 bathrooms $1,200,000 in 2025, 3 or more bathrooms $1,973,750 in 2026. The 2-bathroom house fell in 2023, 2026.
- Benchmark: all bathroom counts combined, the median house in Saint-Lambert sells for $1,120,000 in 2026 (January to September) (all-types series); the 2-bathroom house sits below that benchmark.
Is the second bathroom worth paying for in Saint-Lambert?
In Saint-Lambert, the second bathroom costs little: $115,000 (+12%). That means 2-bathroom houses look like the others: same age, same size, a bathroom added in the basement. The buyer who wants the second bathroom pays almost nothing extra; the seller who thinks the new bathroom is worth a fortune has the wrong city. The third bathroom, for its part, costs $883,750 (+81%): in Saint-Lambert, the 3-plus-bathroom house is the large recent home with an ensuite, and its market is narrow (20 sales from January to September 2026).
How to read these numbers
One median per year and per bathroom count, for all of Saint-Lambert. 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.
