Washdown One-Piece Toilet, 10/12 Inch Rough-In, 700 × 390 × 740 mm
HSJ-2497 is a floor-mounted washdown one-piece toilet in white ceramic. The catalog prints one size for the model: 700 × 390 × 740 mm (27.6 × 15.4 × 29.1 in). Floor-drain installs choose a 250 mm (10 in) or 300 mm (12 in) S-trap rough-in, and wall-drain installs use a 180 mm P-trap outlet. Kitchen and bath dealers can show one display model to customers on 10 or 12 inch drains and keep the outlet as the only choice on the order.

FAQs
Is the HSJ-2497 washdown one-piece toilet available as a P-trap WC?+
What is the HSJ-2497 size?+
How does HSJ-2497 compare with HSJ-2427?+
HSJ-2497 washdown one piece toilet lists a length of 700 mm (27.6 in) and a width of 390 mm (15.4 in). Overall height is 740 mm (29.1 in), completing the printed length × width × height. The catalog lists S-trap rough-ins of 250 and 300 mm and a 180 mm P-trap outlet for the white ceramic body. Verify the printed size against the official technical drawing.
The HSJ-2497 S-trap toilet bowl is listed at 250 mm (10 in) or 300 mm (12 in) rough-in. The P-trap WC is listed at 180 mm. One model therefore covers 3 outlet conditions, each ordered as its own line. Each RFQ line states its outlet entry and toilet count, with washdown flush and white ceramic fixed. Confirm against the model spec sheet for each outlet before release.
Washdown is the one flush printed for HSJ-2497. The one piece toilet design joins tank and toilet bowl in white ceramic, the single listed color. Flush and color are the same on every HSJ-2497, so the RFQ only varies outlet entry and count. Request written confirmation from the factory of the outlet split and quantities before production. One printed size covers every entry.
