What we see on O'Fallon homes
The median house in O'Fallon went up in 2000, and 80.4% of the town was built from 1990 onward. 35,553 housing units, 80.2% of the occupied ones owner-occupied. That is a high share, and it means most of these conversations are with the person who will live with the result rather than with somebody signing off on a property they never see. 17.7% 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.
