Height And Flush
A 773 mm body described as comfort height
The title puts 6638 at 30 inches tall and calls it comfort height. The published height entry is 773 mm.
Overall height is not seat height
Comfort height refers to where the seat sits. The record publishes the overall body height only, so ask for the seat figure separately.
Title and tag disagree on flush
The title says single flush while the listing tag records dual flush. Have the flush arrangement confirmed in writing before ordering.
Comfort height and standard bodies are often quoted together on one project. Both sit in the one-piece toilet line.
Fit & Clearance
Why 30 inches tall does not fix seat height
The title quotes 30 inches while the size line reads 773 mm.
The title describes the configuration. Before this model goes into an accessibility submittal, request dimensional evidence for the seat height.
Rough-in is also missing from the record. The dimensional drawing settles both figures and we issue it on request.
Never submit a height claim without the drawing behind it.
Construction & Finish
Material entries on a taller skirted pan
The material record on 6638 is short and worth reading exactly.
Name given, method withheld
One line covers the body and it names the material. Nothing on this page describes how that body is made, and nothing here should be quoted as if it did.
A taller body shows more of the skirt to the room. Ask for a sample if this model is going onto a display floor.
Display units should be checked against the shipped sample.
Compliance
Accessibility wording and what evidence it needs
A description in a title is not an approval. Ask for measured evidence whenever a height claim reaches a specification.
No approval or accessibility mark is recorded for 6638. The title describes the configuration, so request dimensional evidence before submittal.
The flush contradiction in the listing has to be settled before any document is quoted. A file that names the wrong flush type comes back from review.
Procurement
Points to settle before ordering 6638
Volume starts at 30 pieces, but the flush type comes first.
Carton print and instruction sheets are handled through the SANIKB OEM and ODM program. Settle the flush question before any artwork is printed.
Include these details with the RFQ
- Confirmed flush arrangement
- Seat height on the drawing
- Quantity and delivery window
- Destination port and Incoterm
- Seat and cover scope
- Carton print and shipping marks
- Documents required at destination
Printed artwork should wait until the flush type is confirmed.

Model 6638 is a floor-mounted, one-piece toilet cast in glossy white vitreous china with an elongated bowl and a modern skirted, concealed-trapway body that wipes clean in seconds. It measures 27.4 x 15.2 x 30.4 in and sits in the tall size class, paired with a dual-flush valve actuated by a top button.
Model 6638 runs a siphonic dual-flush at a standard 1.28 GPF (4.8 L) full and about 0.8 GPF reduced, mounted to a standard 12 in (305 mm) rough-in so installers match common North American waste outlets. As factory-direct production, SANIKB controls vitreous-china casting, glazing and quality control in-house, and OEM flush volumes can be configured to your market water-consumption rules.

The tall footprint of Model 6638 makes it a practical specification for buyers standardizing one-piece toilets across a project. Typical fits include:
- Residential and light-commercial bathrooms preferring a taller tank profile
- Multi-unit residential and dealer floor stock
- Hospitality guest rooms
- Projects standardizing on a single elongated one-piece across many units
As a one-piece toilet OEM and ODM manufacturer, SANIKB supports private-label programs on Model 6638 so importers and brands can build a cohesive bathroom assortment under their own identity. Programs can include:
- Your logo and branding on the product and packaging
- Custom cartons, inserts and documentation
- Branded fittings and tailored model variants
- Configured flush volume to suit your market water-consumption rules
Model 6638 is supplied factory-direct at an MOQ of 30 pcs, which keeps trial orders and mixed-model container loads workable. Distributors, importers, dealers and project buyers deal with the manufacturer rather than a trading layer, with direct pricing and consistent batch quality across repeat orders. Combine Model 6638 with other sizes from the one-piece range in a single shipment, then request a quote with your target quantities and destination port.
Model 6638 is high-fired vitreous china, supplied cUPC-ready for North American projects, with exact certificate scope confirmed per model and market. In-house QC covers kiln firing, glaze coverage, water-tightness, flush-and-drain function and dimensional checks before packing, and the unit is crated in foam-cushioned export packaging engineered for ocean freight. Third-party and pre-shipment inspection are welcome so your team verifies build quality before goods leave the plant.
