FAQs

What defines Model 6638 and how is it built?+
Model 6638 is a tall-profile one-piece toilet cast from vitreous china in a glossy white glaze. It pairs an elongated bowl with a modern skirted body, so the trapway is fully concealed behind a smooth side panel for easier wipe-down and a clean fixture face. It runs a dual-flush system actuated by a top-mounted push button. As a single-piece casting there is no tank-to-bowl seam, which removes a common leak and assembly point for downstream installers.
What are the dimensions of Model 6638 and which projects suit a tall unit?+
Model 6638 measures 27.4 x 15.2 x 30.4 in (W x D x H), placing it in our tall class at 30.4 in overall height. The taller silhouette gives a more substantial presence and reads well in standard-to-spacious bathrooms, hospitality suites, and residential builds where buyers want a fuller-bodied fixture. Confirm seat and rough-in figures against the spec drawing before committing to a layout, since fit depends on the finished installation footprint rather than overall height alone.
How is Model 6638 installed and what should be verified first?+
Model 6638 is floor-mounted and bolts to a standard floor flange, shipping as one piece so there is no on-site tank assembly. Model 6638 uses a standard 12 in (305 mm) rough-in so installers match common North American waste outlets; confirm the exact rough-in on the spec drawing per shipment. For procurement teams spec'ing across a project, confirm the drawing for each model in the lineup; you can review the full skirted one-piece toilet range to match rough-in needs across units.
What flush system and button does Model 6638 use?+
Model 6638 uses a dual-flush valve with a top-mounted push button, giving users a separate solid and liquid selection from a single control on the tank top. Top actuation keeps the button within easy reach on a tall unit and presents a clean, uncluttered top surface that suits markets used to deck-mounted controls. Model 6638 runs a siphonic dual-flush at a standard 1.28 GPF (4.8 L) full and about 0.8 GPF reduced; OEM flush volumes can be configured to your market water-consumption rules.
How does Model 6638 compare to other tall dual-flush models?+
Within the tall dual-flush group, Model 6638 at 27.4 x 15.2 x 30.4 in sits between the more compact 26.8 in-wide tall Model 6618 and the wider 27.9 in-wide Model 2025. All three share the skirted elongated vitreous china body, top-button dual flush and floor-mount install, so the choice comes down to footprint: 6638 offers a mid-range width and depth that fits standard bathrooms without the larger bowl projection of the wide-class units.
Is there a single-flush alternative if a buyer prefers one button action?+
Model 6638 is dual-flush only. Buyers in markets that prefer a single flush — or who want to simplify SKUs and end-user training — can look to a single-flush sibling such as Model 6654, which keeps the same one-piece skirted elongated vitreous china construction with a top button but uses a single-flush valve. Both ship floor-mounted in export crating, so a mixed order across flush types stays consistent on freight and packaging.
What are the procurement terms and compliance for Model 6638?+
Model 6638 is supplied factory-direct by SANIKB, so importers, distributors and project buyers source from the manufacturer that controls the casting, glaze and QC line — not a trading layer. It is cUPC-ready for North American projects (confirm current certification scope at quote stage) and ships in export-grade crate packaging built for ocean freight. MOQ is 30 pcs, and OEM/ODM and private-label programs are available for branded packaging, logo glazing and custom cartons.
