Siphonic One-Piece Toilet, 8/10/12/16 Inch Rough-In, 720 × 370 × 790 mm

HSJ-2343 is a 28 inch siphonic one piece toilet, 8/10/12/16 inch rough-in options covering 200 to 400 mm floor drains. Siphonic is one of two flush versions; washdown is the other. The buyer measures each drain, finds the matching printed value, and writes it on the RFQ line. A building with uneven slabs can stay on one model and still match every drain. Confirm against the model spec sheet before releasing the order, and keep the drain readings with the purchase file.

Flush type on HSJ-2343 is a line-level choice: siphonic or washdown, confirmed at quotation. Projects with a house standard for flush type keep every line on the same version. Mixed projects split lines by room type. White ceramic is the listed color for both versions. Request written confirmation from the factory of the flush version on the final order. Siphonic and washdown entries share the printed 720 × 370 × 790 mm size, since one size is printed for the model. A schedule column for flush type next to rough-in and outlet keeps the split readable for site teams and the quotation desk alike.

Wall-waste rooms use the HSJ-2343 P-trap version, printed at 180 mm. This entry pairs with either flush version. Sites with both floor and wall wastes can use either entry room by room. Keeping one model across those rooms simplifies spare stocking and site training. Record outlet type beside every room on the survey sheet. The P-trap line then sits beside the S-trap lines at 200, 250, 300 and 400 mm under one model code. Floor mounted placement and white ceramic apply to all of these entries, so outlet and flush are the only variables a buyer sets.

Length on HSJ-2343 reaches 720 mm (28.3 in), the longest of the three printed dimensions. Width is 370 mm (14.6 in), height 790 mm (31.1 in). Siphonic and washdown versions share this size across S-trap rough-ins of 200, 250, 300 and 400 mm. Verify against the official technical drawing before fabrication of tiled surrounds. The 28 inch name rounds the 28.3 in length, so the millimeter value should drive decisions rather than the label.
