As more homeowners plan to stay in their homes rather than downsize, aging-in-place remodels - walk-in showers with grab bars, wider doorways, lower counters, no-step entries - are a steadily growing category, often requested by adult children planning ahead for aging parents, not just by seniors themselves.
This is a genuinely underserved niche most remodelers don't market to directly, despite doing work that already qualifies. A dedicated page or a few blog posts on this topic can capture a motivated, less price-sensitive audience with comparatively little competition.
