Two public records describe Swannanoa's housing, and they do not quite agree — which is the most useful thing to know before a conversion. The Census place pins the median build year at 1985 with 42.5% of homes pre-1980; Buncombe's appraisal file, sorted by Swannanoa situs address across the broader valley, reads older at 1980 and 49.7%, with 59.1% of its 3,424 homes built before 1990. Both are right about their own map. For a tub-to-shower job the difference is concrete: where you sit in the valley predicts whether demo meets cast iron or fiberglass behind the tile.
What the two maps mean behind your tile
The newer CDP-edge homes — the ranches and infill that pull the Census median to 1985 — usually gave their bathrooms a one-piece fiberglass tub-shower set against bare studs, the cleanest conversion we do: sectioned out in a morning, open framing ready for backer and membrane. The older situs-area cottages the county file captures tend toward a cast-iron tub at 250 to 400 pounds and galvanized supply lines at the valve, both worth retiring while the wall is open rather than burying behind new finishes. Neither outcome changes whether the conversion works; both change the labor line, which is why we price after seeing the room and not from a phone script.
A stay-put market, not an aging-in-place one
Swannanoa breaks the Western NC pattern in a way that should shape the project. At 16.4% residents 65-plus it is genuinely young for the region, and at 78.6% owner-occupied it is overwhelmingly people remodeling a home they intend to keep. That points the spend toward daily quality of life — a real standing shower, a niche your shampoo fits, glass instead of a sticking curtain — rather than the seated-and-low priorities a heavily-elderly town would lead with. We still build a low or zero threshold when an owner wants to plan ahead, but here it is a choice made early, not a reaction to need.
| Scope | Low | Typical | High |
|---|---|---|---|
| Tub-to-shower conversion — one-day acrylic liner system | $1,200 | $4,500 | $9,500 |
| Tub-to-shower conversion — full custom tile | $3,500 | $8,000 | $15,000 |
| Walk-in shower, installed (all types) | $3,500 | $8,000 | $15,000 |
| Walk-in shower — custom tile with frameless glass, installed | $3,500 | $9,000 | $15,000 |
Every Swannanoa figure traces to HomeGuide / Angi — Tub to Shower Conversion Cost (2026), with the Cost vs. Value South Atlantic report for resale context. On a $247,600-median valley home the smart move is keeping the existing drain and putting the budget into the surface you touch daily — that holds your job to the low half of each band.
Built to outlast the owner who paid for it
Because these are houses people keep, the part nobody sees is the part that matters most: a continuous bonded waterproofing assembly — membrane on the walls, sloped and sealed pan, banded corners and curb or recess — under every tiled conversion we set in the valley. Tile and grout are the finish, not the watertight layer, and confusing the two is how a quiet leak becomes a framing repair a decade on. We install the names any Buncombe plumber will still service in 2050 — Schluter membranes, Kohler, Moen and Delta valves — file permits through Buncombe County Permits & Inspections, and keep our license checkable at the NC Licensing Board for General Contractors.
