What we see on Florissant homes
The median house in Florissant was built in 1963, and 76.7% of the housing stock there predates 1970. 23,221 housing units, 66.5% of the occupied ones owner-occupied. That leaves a real share of rented property, and a landlord asks different questions than an owner: what fails soonest, what a tenant will call about. The quote is the same either way. Only 1.4% predates 1940. Most bathrooms here have been done once already, and the question is usually whether whoever did it moved the plumbing or worked around it.
Bathrooms in postwar houses are typically five feet across with the tub at one end, and the tile is either original or an eighties refresh laid over the top of it. Where those rooms fail is the grout at the tub-to-wall joint. Water has been getting behind it for years by the time anyone notices the floor flexing. Once the surround is out we can see how far it traveled, and that is the point where the honest scope of the job becomes clear. On a shower specifically the real question is usually whether the tub stays at all, because the conversion is much the same job either way.

What the water does here
Missouri American Water, St. Louis County publishes a total hardness of 4 to 13 grains per gallon for Florissant, which is hard at the top of the range.
Hardness that swings across the year is harder on a bathroom than a steady number, because the scale builds fastest at the top of the range and then stays. Grout takes it worst, because it is porous, so the calcium goes into the joint rather than onto it. High Performance Polymer Acrylic has no joint, which is the practical difference between resealing a shower every couple of years and leaving it alone.
