Size at a glance

Axis order sourcedDrawn to scale from the published dimensions. Manufacturer states: 19.69 × 20.87 × 34.65 in; net 73.9 lbs — 34.7 in (880 mm) high, 19.7 in (500 mm) wide, 20.9 in (530 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 880 mm last, width 500 mm and depth 530 mm first (Harvia spec). Confirm against the installation manual before cutting anything to fit.
