The construction choices that decide the decade
Box and core materials set moisture behavior: plywood boxes tolerate humidity swings and hold fasteners well; quality engineered cores with fully sealed edges also serve, while raw or thinly sealed cores at cutouts and edges are where swelling starts. The sink cutout is the tell, a sealed, clean cutout marks a maker who understands the posting; a raw one forecasts the failure photo.
Fronts, finishes, and hardware carry the daily interaction: painted and film fronts want quality substrates to resist edge peel in humidity; catalyzed and factory finishes outlast site-brushed ones; and drawer slides plus hinges are the vanity's moving parts, where soft-close quality and load ratings are felt every single day. Drawers themselves reward dovetails or robust joinery, because the toothpaste drawer cycles thousands of times.
The room's plumbing and floor finish the audit: cutouts for supplies and drain should be tight and sealed, not torn; floor contact matters in wet rooms, legs and toe-kicks handle puddles differently, and wall-hung boxes exit the puddle conversation entirely at the price of carrier framing. Stock, semi-custom, and custom span the same construction questions at rising freedom: sizes and finishes first, then dimensions and interiors, then geometry itself.
