What we see on Waterloo homes
The median house in Waterloo went up in 1991, and 51.9% of the town was built from 1990 onward. 4,651 housing units, 76.9% of the occupied ones owner-occupied. Mostly owners, then, which usually means the decision turns on how long you plan to stay rather than on what it does to a rent roll. 15.2% has been built since 2010, which means a lot of original builder fixtures now at the age where the surround and the seals start to go.
Bathrooms in post-1990 houses are bigger than what came before, often with the tub and shower separated, and they are now at the age where the finishes are dated rather than failed. That is a different conversation. There is no water damage to chase, so the real question is whether the tub is earning its floor space. A lot of people in these houses convert an unused garden tub to a walk-in shower and take the room back. On a full remodel the order is what matters: the room comes out, whatever is behind the walls gets put right, and only then does anything new go in.
