Does HSJ-2332 have a rear outlet version?+
HSJ-2332 is a 25 inch washdown one piece toilet, with 4/8/12/16 inch rough-in listed as S-trap options. Washdown is the single flush type printed, so the flush field on every RFQ line reads the same. Printed length and width are 640 × 370 mm (25.2 × 14.6 in). White ceramic is the listed color. That leaves outlet type and quantity as the two decisions for each room. HSJ-2332 prints 640 × 370 × 685 mm; the HSJ-2202 one-piece toilet prints 680 × 380 × 670 mm, so the buyer can weigh the two bodies on paper.
S-trap settings on HSJ-2332 run 100, 200, 300 and 400 mm, or 4, 8, 12 and 16 inches. Each is measured from the finished wall to the floor drain center. Short settings help where the drain sits tight to the wall. Long settings help where the drain sits far out from the wall. Request written confirmation from the factory of the version picked on each line. Writing the measured distance beside the room count on the survey sheet makes the rough-in split easy to check later. A project can carry all 4 settings under one model if the slab readings call for it.
Rear discharge rooms take the HSJ-2332 P-trap entry, printed at 180 mm. This entry serves bathrooms where waste pipes run inside walls. The P-trap and S-trap entries share the model code, so a mixed building can order one product with several outlet lines. Note outlet type and rough-in on the schedule for each bathroom before the RFQ. Washdown flush applies to the P-trap entry just as it does to the floor-drain entries. White ceramic is the listed color throughout, so the wall-outlet rooms match the rest of the building visually.
Overall height on HSJ-2332 is 685 mm (27.0 in). Width is 370 mm (14.6 in) and length is 640 mm (25.2 in), printed in that model's spec as 640 × 370 × 685 mm. S-trap rough-ins of 100, 200, 300 and 400 mm are listed for this washdown body. Verify against the official technical drawing before fabrication of any tiled boxing. The 25 inch label rounds the 25.2 in length, so a buyer comparing listings should read the millimeter figure as the reference.
