Flush System
A siphonic flush with a tornado flush port
The flush is listed as siphonic with a tornado flush port. The valve opening is 2 inches and the published single flush volume is 1.28 gpf, given as 4.8 litres.
2 inch flush valve
The flush valve is listed at 2 inches. Spare parts are ordered against that opening size, so record it in the maintenance file at handover.
1.28 gpf single flush
Single flush 1.28 gpf (4.8 L) is the standard build. A 1.06 / 1.28 gpf dual flush version is available on request and is fixed at the production order.
Flush configuration is set at the production order, so it has to be stated in the purchase order. Other bodies in this format are listed in the one-piece toilet range.
Fit & Clearance
Setting a 700 by 385 mm body on a 305 mm rough-in
The published dimension set is 27.6 by 15.2 by 30.7 inches, given as 700 by 385 by 780 mm.
Rough-in is listed at 305 mm, measured from the finished wall to the outlet centre. Ceramic rim height is listed at 420 mm (16.5 in), measured to the china rim with the seat excluded, so add the seat thickness before you compare that figure against a drawing that includes the seat.
Check the 305 mm rough-in against the slab drawing before the order is released.
Construction & Finish
One-piece vitreous china with a fully glazed trapway
Material is listed as vitreous china in a one-piece body. The trapway is listed as fully glazed and the finish is glossy white.
Finish and glaze
A soft-close seat is supplied with the fixture. Confirm in the carton specification that the seat is packed with every unit, and state who holds replacement seats after handover.
The fully glazed trapway is a published construction detail, so put it in the incoming inspection sheet with the glaze tone and the flush valve size.
Agree a damage reporting window with photographs before the first shipment.
Compliance
Listing paperwork is issued against model 1938
Request paperwork against model 1938 by name. On a mixed-model container each reference is documented separately.
1938 is cUPC listed. The published specification also holds material, type, mount, finish, size and MOQ. Before it goes into a submittal, request the current listing number and certificate validity so the documentation matches your destination market.
Requirements differ by destination market. State the market and the documents your submittal needs in the enquiry; both are settled at quotation stage. Enquiries are answered within 12 business hours.
Procurement
Container planning at 50 pieces
Published minimum order quantity is 50 pieces, and a mixed 1 × 20 ft container is accepted.
A mixed 1 × 20 ft container lets this reference share a load with other models on the same order, which keeps the 50 piece minimum from setting the size of the whole shipment. Private label work is handled through the SANIKB OEM and ODM program.

- Destination market and port
- Single flush 1.28 gpf or the 1.06 / 1.28 gpf dual flush build
- Seat and cover scope

Lead time is listed at 30–45 days after deposit and stays indicative until the quotation is issued.

Model 1938 is a one-piece tornado flush toilet in vitreous china, floor-mounted with an S-trap. The figures below are the published specification and are the set used for submittals.
- Overall size 700 × 385 × 780 mm (27.6" × 15.2" × 30.7")
- Rough-in 305 mm (12 in), finished wall to outlet centre
- Ceramic rim height 420 mm (16.5 in), seat not included
- Siphonic flush with tornado flush port, 2 in flush valve
- Single flush 1.28 gpf (4.8 L); 1.06 / 1.28 gpf dual flush on request
- Fully glazed trapway, glossy white, soft-close seat supplied
- cUPC marked. MOQ 50 pcs, mixed 1 × 20 ft container accepted
The flush is listed as siphonic with a tornado flush port. The flush valve opening is 2 inches, which is the figure to record for spare parts.
Single flush 1.28 gpf (4.8 L) is the standard build. A 1.06 / 1.28 gpf dual flush build is available on request. The build is set at the production order, so the flush configuration has to appear on the purchase order rather than being chosen at installation.
Rough-in is 305 mm (12 in) from the finished wall to the outlet centre, with an S-trap outlet. The body measures 700 mm front to back and 385 mm across, with an overall height of 780 mm.
Ceramic rim height is listed at 420 mm (16.5 in). That figure is measured to the china rim and excludes the seat, so add the seat thickness before comparing it with a drawing that quotes a figure taken over the seat. Clear floor space rules differ by market; verify them against the drawing at design stage.
The body is one-piece vitreous china with a fully glazed trapway. The finish is glossy white, and a soft-close seat is supplied with the fixture.
Put the glaze tone, the fully glazed trapway and the 2 inch flush valve size on the incoming inspection sheet so each container is checked against the same list.
1938 is cUPC listed. Documents are issued per model rather than per range, so request the current listing number and certificate validity against 1938 by name before the submittal is filed. On a mixed-model container each reference is documented separately.
State the destination market with the enquiry. Document requirements differ by market and are settled at quotation stage.
Published MOQ is 50 pieces and a mixed 1 × 20 ft container is accepted, so 1938 can share a load with other models on the same order. Lead time is listed at 30–45 days after deposit and remains indicative until the quotation is issued.
Private label work, including brand marking on carton and insert, is handled through the SANIKB OEM and ODM program. Enquiries are answered within 12 business hours.
