Drain before design
Rear outlet toilet sourcing: four checks before you compare models
A rear outlet toilet is bought around a pipe that already sits in a wall, so the drawing matters more than the catalog photo. Work through these four checks in order to narrow the 150 models before styling comes in.
1. Read the spigot height off the drawing
Note where the drain sits in the wall, then compare it with the printed P-trap figure on the drawing. 180 mm is printed on 133 models; the remaining bodies print 135, 150, 170, 175 or 185 mm, and the 135 mm figure belongs to wall-hung smart units.
2. Settle the body type
Wall-hung bowls are listed as wall-hung; one-piece, two-piece and back-to-wall bodies are listed as floor-mounted. Fix which of these the project drawing calls for before comparing outlets.
3. Ask whether a floor drain is also in play
Many floor-standing bodies print an S-trap figure next to the P-trap one, which gives the same body a second outlet option for rooms with a floor drain. If one order serves buildings with both drain types, shortlist those dual-outlet bodies.
4. Fix flushing system and color last
Once the outlet and body type are settled, choose washdown, swirl, rimless, dual jet or siphonic, then the glaze color. Flushing is fixed per model, and most models list one glaze; TC-7311, TC-7102 and TC-7002 each list two.
Keep the drawing from each product page with the order file; the installer will need it before the wall is closed.

Models with a reason
Where specific models fit a brief
Some bodies stand out for a concrete spec reason rather than looks. These are the ones worth naming in an inquiry.
Matched two-piece setTC-7304, TC-7305, TC-7308 and TC-7309 print the same 640 × 350 × 800 mm size, CE mark and 8 / 10 in S-trap plus 180 mm P-trap, so a distributor can stock four designs with identical printed figures.
Wall drain onlySL-8016 and its sister SL-8015 print a 180 mm P-trap and no S-trap figure, for orders where only the wall outlet is needed.
Longer floor rough-inNBK-3076 is the only model in the table above printing a 12 / 16 in S-trap pair alongside its 180 mm P-trap.
Colored wall-hungTC-7006G in gray and TC-7107B in black are rimless, CE-marked wall-hung bowls with a 180 mm P-trap.
Bidet featureSL-8848, SL-8048H and TC-58107H carry a bidet feature tag on one-piece bodies with dual S-trap and P-trap outlets.
Two glazes, one bodyTC-7311 comes in white or marble on a 670 × 370 × 790 mm two-piece body.Who orders these
Typical rear outlet toilet buyers
Wall-drain plumbing shows up in a few predictable kinds of B2B orders.
Distributors in wall-drain markets
For markets plumbed through the wall, the range spans one-piece, two-piece, wall-hung, back-to-wall and smart bodies, and each model is quoted as its own line, so one container can mix body types.
Renovation contractors
Replacing an old unit starts from the existing wall drain. Bring its measured position; many floor-standing bodies also print an S-trap setting as a second outlet option.
Hotel and apartment developers
Repeating floor plans favor one body across many rooms. Pick a model whose printed outlet matches the riser design and order it in a single color code.
Private-label brands
Own-brand product and packaging run through the OEM/ODM service. Marks such as CE are confirmed per model, since only some models carry one.
Inquiry checklist
What to put in a rear outlet toilet RFQ
A quote comes back faster when the first message already answers the questions the factory would ask. For a back outlet toilet order, list each model code with its quantity, the P-trap height your drains use, and whether the same unit must also accept an S-trap connection and at which rough-in.
Add the flushing system, glaze color, the certification mark your market requires, carton marking, and the destination port. Pricing is quoted per order and MOQ is set per model, so mixed orders are normal.
Written replies arrive within 12 business hours. For your own brand on the product and packaging, see the OEM and ODM service.
Rear outlet toilet supply in this collection covers 150 ceramic models, from 470 mm wall hung bowls to 750 mm floor-standing bodies. Projects with drains running through the wall can choose from one-piece, two-piece, wall hung, back-to-wall and smart toilet bodies. Each model is quoted as its own line, so a single project can mix several body types in one order.
Rear outlet toilet planning starts from the printed P-trap height, which is 180 mm on 133 models here. Other models list 135, 150, 170, 175 or 185 mm, so filter by outlet height before fixing the drain position in the wall. Many floor-standing models also list an S-trap setting, which gives the same body a second outlet option for rooms with a floor drain.
Rear outlet toilets here list washdown on 54 models, swirl on 39, rimless on 27, dual jet on 15 and siphonic on 13. White is listed on 146 models and black on 17, with gray, beige, gold, green, marble and other colors on selected models. Flushing style and color are fixed per model, so choose the combination first, then compare footprints and outlet heights.
