There is nothing else in the SHUIDAO basin range that looks like this. The AR-015 is an origami construction translated into vitreous china — a vessel basin whose entire formal vocabulary is built from flat, angled planes meeting at sharp creases, with no curve anywhere in the design. The exterior is a faceted diamond-like form finished in deep matte black, each flat panel meeting the next at a crisp folded edge. The interior bowl is a contrasting high-gloss white, its angled flat walls converging toward an offset matte black drain that anchors the basin's geometric composition. The diagonal division between black exterior and white interior — the gloss inner surface cutting across the matte outer rim at a sharp angle — is the basin's most arresting detail: a two-tone origami fold that makes the AR-015 as much a design object as a functional fitting.
Colour is the first thing the AR-020 says, and it says it without apology. A deep, saturated forest green — the kind of green that reads simultaneously as botanical, architectural, and quietly luxurious — covers every surface of this vessel basin in a uniform matte finish that absorbs light rather than reflecting it. The form underneath the colour is a rounded square: not quite a circle, not quite a square, but the gentle hybrid between the two that ceramic designers refer to as a squircle — four sides that curve continuously into one another with no corner and no straight edge, the rim tracing a soft, closed loop that shifts almost imperceptibly as the eye follows it around. A white centre drain provides the only colour contrast, sitting flush at the bowl floor as a deliberate white accent against the deep green field.
The CT-014 is a study in considered restraint — a back-to-wall close-coupled unit that takes the tall rectangular cistern of the CT-001 series and pairs it with a fully rounded, compact skirted pan, then unifies the two with a top-flush button that keeps every visible face clean and uninterrupted. Two small fixing points are visible on the side of the pan body — likely water inlet or wall-bracket connection points — suggesting a design engineered for precise back-to-wall installation. The overall proportion is vertical and composed, with the pan's soft roundness offering just enough contrast to the cistern's strict geometry to prevent the unit from feeling severe.
The CT-004 introduces the most distinctive silhouette in the CT series — a pan body that flares outward from a narrow waist at the cistern join and sweeps dramatically wide at the floor, like the bell of a trumpet caught mid-breath. It is a toilet that owns the floor space it occupies, projecting quiet confidence rather than shrinking into the background. The cistern sits closer to standard height here, its proportions more balanced, making the entire unit feel grounded and complete.
The CT-008 occupies the pragmatic centre of the one-piece range — neither the smooth contemporary sweep of the CT-006 nor the ornate classical relief of the CT-007, but a clean, no-excess form that simply does everything right. The cistern is compact and flat-topped, the skirted pan body is gently rounded without theatrical gesture, and the whole unit presents an honest, resolved silhouette that will harmonise with virtually any bathroom scheme without demanding attention. A dark circular cap is visible at the front base — likely a floor bolt access cover — adding a subtle graphic detail at ground level. cUPC certified for the North American market.
A departure from the two-piece close-coupled forms of the CT series, the CT-006 is a true one-piece toilet — cistern and pan cast and fired as a single, seamless ceramic body. The profile is classically American in proportion: a tall, gently curved cistern flowing without interruption into a fully skirted elongated pan, the whole unit anchored to the floor on a broad, stable base. The chrome side-lever flush handle signals its intended market immediately — this is the CT series' North American export specification, confirmed by the cUPC certification mark visible in the image
The CT-010 is the most architecturally resolved toilet in the CT series — a full commitment to the rectangle from lid to floor, with barely a concession to organic curvature anywhere along its body. The cistern and pan share the same vertical plane on the rear face, creating a single unbroken flat back wall. The sides taper with the gentlest of angles toward the front, and only at the very base do soft rounded corners acknowledge the floor. It is a toilet designed for the bathroom that takes its geometry seriously — where square-edge tiles, flat-front cabinetry, and rectilinear basins demand an equally disciplined sanitary ware specification. The top-flush button replaces the side lever entirely, maintaining the unbroken surface of every visible face. cUPC certified for the North American market.
The CT-012 takes the proportional drama of the CT-011 and introduces a new formal move — a defined waist. Where the CT-011 transitions directly from its tall slim cistern into a broadly swelling pan, the CT-012 narrows deliberately at the mid-body before flaring back out into an expansive oval base that extends generously in all directions. The effect is of a form that gathers itself before opening up — the pan silhouette reading almost like a tulip or a wine glass in profile, with genuine sculptural intentionality. The chrome top-flush button sits neatly centred on the flat cistern lid, and cUPC certification confirms this unit's North American market readiness.
The CT-024 is the most fluid and organically resolved toilet in the CT one-piece range — a unit where the transition from cistern to pan is not a step or a junction but a continuous, unhurried curve that flows the angular cistern form into the rounded pan body with the kind of seamlessness that only a true one-piece casting can achieve. The cistern shoulders angle gently outward and downward before surrendering fully to the oval pan below, and the pan itself maintains this sense of motion — widening evenly, holding its volume through the mid-section, then closing smoothly to the floor. No hard edges interrupt the journey from lid to tile. The chrome top-flush button punctuates the flat cistern top as the only deliberate accent in an otherwise unbroken ceramic composition.
The CT-016 occupies a quietly confident position in the CT series — a one-piece unit that neither reaches for drama nor retreats into neutrality, but finds its character in an unusual formal quality: the pan body is nearly cylindrical. Where most skirted toilet pans taper, flare, or cinch to establish a silhouette, the CT-016's pan maintains an almost perfectly consistent width from the cistern base to the floor, its sides running nearly vertical before closing into softly rounded lower corners. The result is a pan that reads as a solid, stable volume — more column than curve — anchored to the floor with quiet authority. The compact square cistern above mirrors this discipline exactly, and the chrome top-flush button keeps every surface uninterrupted.
The CT-020 finds its identity in balance — a one-piece unit where the cistern and pan achieve a proportional equilibrium that feels settled and complete rather than deliberately contrasted. The cistern is medium in height and width, the pan below it broad and full but not dramatically so, and the transition between the two is smooth enough that the eye reads the unit as a single coherent form rather than two geometric statements. The slightly squared rear shoulder of the pan — visible where it meets the cistern base — adds a subtle structural note that keeps the form from reading as purely organic, while the softly rounded front and sides carry it comfortably into warm, residential territory. The single top-flush button sits centred and small on the flat lid, the only accent on an otherwise pure white surface.
The CT-022 introduces a formal move not seen elsewhere in the CT series — a pan body that tapers. Where most CT pans expand outward from the cistern base or maintain a consistent width, the CT-022's pan is widest at the upper section just below the seat, then narrows progressively and evenly toward the floor, the skirt converging inward to a base that is notably smaller than the pan's mid-section. The effect is of a form that concentrates its volume in the upper body and releases it toward the ground — an inverted proportion that gives the unit a distinctive forward-leaning, slightly elevated visual presence. Paired with the tall rectangular cistern and centred top-flush button, the CT-022 reads as refined, unhurried, and quietly original.
The CT-018 is the most architecturally assertive toilet in the CT series — a unit where the square is not merely present but dominant, governing every face and every corner from cistern lid to floor tile. The cistern rises tall and perfectly flat, the pan body below it carries the same squared geometry with only the most minimal corner rounding, and the two-button top-flush mechanism sits centred on the lid as a chrome accent against an otherwise uncompromising white surface. If the CT-010 was the CT series' commitment to the rectangle, the CT-018 is its full conviction — a toilet that makes no visual concessions and asks the bathroom around it to rise to the same standard.
Clean, low-profile, and unhurried — the SHUIDAO AR-009 is the basin that disappears into a well-designed vanity and lets the rest of the bathroom do the talking. The form is a rounded rectangle held shallow and wide, its exterior walls rising from the countertop with a gentle outward curve before meeting the flat rim in a single clean line. The interior bowl follows the same softened geometry, the corner radius generous enough to feel organic without sacrificing the basin's essential rectangular discipline. A chrome centre drain sits flush at the bowl floor, and the absence of any tap hole keeps the rim surface completely uninterrupted — a detail that signals wall-mounted or deck-mounted tap installation and gives the basin a purity of surface that flat-rim square basins rarely achieve.
Texture is the argument the AR-017 makes — and it makes it confidently. While most vessel basins present smooth, uninterrupted surfaces, the AR-017 wraps its exterior in a dense sequence of precisely spaced horizontal ribs that run continuously around all four sides, each groove casting a thin shadow line that builds into a quietly complex surface pattern. The effect references Japanese woodworking joinery, mid-century ceramic craft, and contemporary architectural brise-soleil — all at once, and without straining for any of them. The interior bowl is smooth and clean, the matte charcoal finish uniform from exterior rib to interior floor, and the offset matte black drain sits positioned toward one corner as a considered compositional detail rather than an afterthought.
The CT-021 is the close-coupled back-to-wall companion to the CT-010's one-piece rectangular philosophy — a two-piece unit that commits fully to the square from cistern lid to floor tile, maintaining sharp edges, flat faces, and right-angle corners at every junction. Where the CT-010 achieves this in a single seamless casting, the CT-021 delivers the same architectural rigour in a more accessible close-coupled two-piece format, making the rectangular design language available at a different price point and installation context. Two small fixing or inlet points are visible on the pan side — consistent with a back-to-wall configuration engineered for precise wall alignment. The chrome top-flush button sits centred and minimal on the flat cistern lid, the only detail on an otherwise uncompromising white surface.
