27 Inch Siphonic One-Piece Toilet, 10/12/16 Inch Rough-In

HSJ-2403 is a 27 inch siphonic one piece toilet, 10/12/16 inch rough-in versions sharing an 820 mm (32.3 in) overall height. Length is 685 mm (27.0 in) and width is 385 mm (15.2 in), so the printed size reads 685 × 385 × 820 mm. A washdown version and a 180 mm P-trap outlet are also listed. Verify against the official technical drawing before fabrication of fitted furniture.

Flush on HSJ-2403 is chosen per line: siphonic or washdown. Both versions are white ceramic and floor mounted, and the model prints one size across them. A hotel or apartment program can keep a single flush type throughout, or split by room type where the specification calls for it. Request written confirmation from the factory of the flush version on every confirmed line so the delivery matches the bathroom schedule.

S-trap entries on HSJ-2403 read 250, 300 and 400 mm, covering 10, 12 and 16 inch floor drains. Wall wastes take the P-trap entry at 180 mm. With 2 flush versions and 4 outlet entries, the model can cover a mixed building under one code. Measure each drain, group rooms by reading, and write flush and outlet on each RFQ line with the toilet count. Keep the survey with the purchase file for the site team.
