Siphonic One-Piece Toilet, 10/12/16 Inch Rough-In, 700 × 370 × 810 mm

HSJ-2201 is a siphonic one piece toilet when ordered in its siphonic version, and the same model code also covers a washdown version. Buyers therefore choose flush type per line rather than per product. Mixed projects can keep one body for both groups of rooms. The printed size is 700 × 370 × 810 mm (27.6 × 14.6 × 31.9 in) for the model. Request written confirmation from the factory of the flush version on each confirmed line.

Back-outlet rooms use the 180 mm P-trap version of HSJ-2201. Floor drains use S-trap at 250 mm (10 in), 300 mm (12 in) or 400 mm (16 in). A drain survey that records outlet type and distance for every room makes the line split straightforward. Floor mounted placement applies to every entry, and white ceramic is the listed color, so neither needs a separate field. Group identical rooms together on the schedule so each flush and outlet pairing appears once with its total count.

Length on HSJ-2201 is 700 mm (27.6 in), set against a 370 mm (14.6 in) width and 810 mm (31.9 in) height. The catalog lists these as length × width × height for every version of the model. Siphonic and washdown flush versions are printed, with S-trap rough-ins of 250, 300 and 400 mm (10, 12 and 16 in) and a 180 mm P-trap outlet. Verify against the official technical drawing before fabrication of boxing or tiled ledges.
