Washdown One-Piece Toilet, 10/12 Inch Rough-In, 700 × 360 × 750 mm

HSJ-2364 is a washdown one piece toilet, 10/12 inch rough-in being its S-trap pair. On outlets, HSJ-2364 prints 250 and 300 mm S-trap; HSJ-2501 prints 250 mm only. On width, HSJ-2501 prints 350 mm; HSJ-2364 prints 360 mm. On height, HSJ-2501 prints 765 mm; HSJ-2364 prints 750 mm. Both list a 180 mm P-trap. Distributors stocking one washdown model for mixed drains can read that outlet list as the deciding line. Confirm against the model spec sheet before the stock order is placed.

S-trap entries on HSJ-2364 sit at 250 mm (10 in) and 300 mm (12 in). A drain survey sorts rooms into those two groups, and each group becomes one RFQ line with its own toilet count. Drains measuring anything else need another model. Floor mounted placement applies to both lines. Keep the measured readings with the purchase file so site teams can match each toilet to its room on delivery.

Rear discharge rooms use the HSJ-2364 P-trap entry, printed at 180 mm. That line pairs with the same washdown flush and white ceramic body as the S-trap lines. Apartment refurbishments with wall wastes on some floors and floor drains on others can stay on one product across the block. Mark the outlet type for each bathroom on the schedule before the quantities are totaled. The P-trap line then sits beside the 250 mm and 300 mm S-trap lines under a single model code.

Washdown is the one flush printed for HSJ-2364, and white is the one color. The one piece toilet design joins tank and toilet bowl in ceramic. Those fixed points leave outlet type and rough-in as the only variables a buyer sets per line. Projects that want a single look across every bathroom can specify this model without color or flush options to manage, and request written confirmation from the factory of the final outlet split.
