29 Inch Washdown One-Piece Toilet, 10 Inch Rough-In

HSJ-2389 is a 29 inch washdown one piece toilet, 10 inch rough-in being its single S-trap entry. HSJ-2389 prints 730 × 430 × 750 mm; HSJ-2365 prints 720 × 390 × 750 mm. HSJ-2389 prints a 250 mm S-trap; HSJ-2365 prints 250 and 300 mm. Both list a 180 mm P-trap and washdown flush. Buyers choosing between them can start from drain readings and available bathroom width. Confirm against the model spec sheet before ordering.

Width on HSJ-2389 is 430 mm (16.9 in). Length is 730 mm (28.7 in) and height 750 mm (29.5 in), listed as length × width × height. The washdown body lists a 250 mm (10 in) S-trap rough-in and a 180 mm P-trap outlet. Verify against the official technical drawing before fabrication of tiled boxing or vanity units. The 29 inch label rounds the 28.7 in length, so use the millimeter values on the plan.

Floor drains for HSJ-2389 must read 250 mm (10 in) from the finished wall to the drain center. Wall wastes use the 180 mm P-trap version. These are the two outlet entries on the order. Washdown flush and white ceramic apply to both. A survey listing each bathroom with S or P and the reading turns straight into RFQ lines with toilet counts. Drains that read 300 mm or more belong to another model.

HSJ-2389 is a floor mounted one piece toilet: tank and toilet bowl form a single white ceramic body. White is the only listed color, and washdown is the only flush. That leaves the design fixed across every line on a project, which suits buyers who want identical toilets throughout a building. The variables left are outlet type and count. Request written confirmation from the factory of those figures before shipment planning.
