FAQs
How narrow is the HSJ-2501 washdown one-piece toilet?+
How does HSJ-2501 compare with HSJ-2364?+
Which drains fit HSJ-2501?+
HSJ-2501 washdown one piece toilet is printed at 700 × 350 × 765 mm (27.6 × 13.8 × 30.1 in), length × width × height. Width is 350 mm, length 700 mm and height 765 mm. The catalog lists a 250 mm (10 in) S-trap rough-in and a 180 mm P-trap outlet for the white ceramic body. Verify the printed size against the official technical drawing.
Floor drains for HSJ-2501 must read 250 mm (10 in) from the finished wall to the drain center, the single S-trap value. Wall wastes use the P-trap entry at 180 mm. Readings at 300 mm or more need a different model. Each outlet entry is quoted as its own line with a toilet count. Confirm against the model spec sheet for both entries. Washdown flush and white ceramic apply to each line.
Washdown is the single printed flush for HSJ-2501, and white ceramic is the single color. The one piece toilet design joins tank and toilet bowl in one body. Projects that need one uniform specification across the order can specify the model without flush or color fields. Outlet entry and count stay as the only variables. Request written confirmation from the factory of the outlet split before shipment planning. Both outlet entries are floor-mounted.
