28 Inch Washdown Two-Piece Toilet, 10/12 Inch Rough-In

HSJ-3007 is a 28 inch washdown two piece toilet with 10/12 inch rough-in versions printed at 250 and 300 mm. Survey every bathroom before quoting: measure the floor drain, record the reading, and match it to one of those two values. Wall-waste rooms skip that step and take the 180 mm P-trap version. Group rooms by version and total the toilet counts. Request written confirmation of the version split from the factory before production starts.

HSJ-3007 is a two-piece toilet: tank and bowl are separate ceramic pieces in white. Washdown is the single flush. The model is floor-mounted, with the outlet leaving through the floor on S-trap versions and through the wall on the P-trap version. One printed size, 700 × 380 × 790 mm, applies to the model. Buyers can list it across a building with outlet as the only variable per line. Rooms with 10 inch and 12 inch drains can go on the same purchase order.

Length on HSJ-3007 is 700 mm (27.6 in), the first figure in its printed size. Width is 380 mm (15.0 in), and height is 790 mm (31.1 in). The catalog reads these as length × width × height. Washdown is the listed flush, and white ceramic is the listed color. Verify these figures against the official technical drawing. The 28 inch label rounds the 27.6 in length, and the millimeter figures are the printed values.
