Axis order sourcedDrawn to scale from the published dimensions. Manufacturer states: 16 × 13 × 33 in — 33 in (838 mm) high, 16 in (406 mm) wide, 13 in (330 mm) deep. The figure is a 1.75 m (5 ft 9 in) reference, not a supplied photograph. Outlines show overall size only. The string above does not label its axes. We read it as W × D × H — Harvia's measurements table for this SKU lists height 33 in last, width 16 in and depth 13 in first (Harvia spec). Confirm against the installation manual before cutting anything to fit.
