Duravit Starck 3 Two-Piece Elongated 1.28 GPF Toilet

Duravit Starck 3: Philippe Starck's Two-Piece Classic — Restrained Modernism for Traditional Rough-Ins

The Duravit Starck 3 Two-Piece Elongated 1.28 GPF Toilet is the rare premium two-piece — most premium-tier Duravit specifications go to one-piece or wall-hung form factors, but Starck 3 exists for buyers who need a two-piece configuration (typically because of existing 12-inch floor rough-in geometry, or because they want the slightly easier serviceability of a two-piece) but refuse to compromise on Philippe Starck's design language. The result is a refined two-piece with cleaner tank-to-bowl proportions than competing brands, more deliberate edge transitions on both tank and bowl, and a profile that reads premium-modernist where Kohler Cimarron and American Standard Cadet 3 read functional-traditional. At its price (typically $799-$1,099 in White Alpin), Starck 3 is more expensive than mainstream US two-piece toilets but delivers Duravit-quality ceramic finish and Starck design pedigree at a meaningfully lower price than Starck 2 one-piece or wall-hung variants.

HygieneFlush Rimless Bowl Design

Starck 3 uses Duravit's rimless HygieneFlush — the same technology found across Vero Air, ME by Starck, and other premium Duravit models. The bowl interior has no traditional rim cavity where mineral deposits and bacteria accumulate. Water enters from a precisely-engineered single-channel inlet that distributes around the bowl perimeter for full rinse on every flush. Combined with the 1.28 GPF water volume, Starck 3 delivers MaP 800g+ flush performance with excellent bowl rinse — well above the regulatory minimum (350g) and competitive with premium one-piece toilets at higher price tiers.

Optional WonderGliss Upgrade

WonderGliss hydrophobic glaze is available as an upgrade on Starck 3 ($60-$120 premium over standard glaze). For hard-water regions or high-use bathrooms, the upgrade meaningfully reduces cleaning frequency over the toilet's service life. For typical residential use with moderate water hardness, the standard glaze is fully adequate — WonderGliss is a nice-to-have, not a necessity. HygieneGlaze antibacterial glaze is also available as a separate upgrade for healthcare-adjacent applications and shared bathroom installations.

Two-Piece Construction Advantages

The two-piece form factor (separate tank and bowl) offers practical benefits over one-piece designs:

• Shipping and handling: easier and cheaper to ship in two boxes, less damage risk in transit
• Installation: easier to maneuver in tight bathrooms — bowl installed first, then tank attached on top
• Serviceability: internal flush mechanism is more accessible for repair or upgrade compared to one-piece designs where the tank and bowl share a single ceramic body
• Replacement: if the tank cracks (impact damage), you can replace just the tank rather than the entire toilet unit (subject to Duravit replacement part availability)
• Rough-in flexibility: Starck 3 fits standard 12-inch rough-in (the dominant US residential standard) — easier retrofit than wall-hung Duravit models that require in-wall plumbing rework

Designer Profile and Proportions

Starck 3 maintains the visual restraint of the Starck design language while accommodating two-piece geometry. The tank is taller and slimmer than typical American two-piece toilets — closer to European tank proportions — which results in a more vertical-leaning silhouette rather than the squat traditional American profile. The bowl is elongated (closer to 17.5" length than a round 16.5"), the seat height is ADA comfort height (~16.5 inches floor to rim), and the bowl width is approximately 14 inches. Tank-to-bowl proportions are designer-tuned: the tank doesn't visually overwhelm the bowl, and the transition between tank and bowl is clean without the bulky molded-in tank base found on most mainstream two-piece toilets.

Installation Requirements

Starck 3 fits standard US residential rough-ins and is significantly easier to install than wall-hung Duravit models. Typical installation:

• Standard 12-inch closet flange (most US homes built post-1970)
• Cold water supply line, 3/8" or 1/2" compression fitting
• Bowl placed over flange with wax ring sealing the connection to the building drain
• Tank installed on top of bowl with tank-to-bowl gasket and mounting bolts
• Flush mechanism connected and tested
• Seat installed on bowl (separate purchase)

Total installation time: 1.5-2.5 hours for an experienced plumber. Installation labor: $200-$400 depending on metro area.

Care and Cleaning

• Standard glaze: any porcelain cleaner safe — Lysol, Clorox, Soft Scrub with Bleach, Scrubbing Bubbles. Pumice stones safe for mineral deposit removal.
• WonderGliss upgrade: gentle cleaning recommended — microfiber + mild dish soap for daily use, periodic Method or eco-friendly bathroom cleaners. Avoid abrasive powders that compromise the hydrophobic treatment.
• HygieneGlaze upgrade: standard cleaning is fine. Avoid extended bleach soaks (overnight) which can degrade the silver-ion antibacterial efficacy over time.
• All variants: AVOID steel wool, harsh acidic cleaners in extended dwell, and impacts from dropped cleaning tools (especially metal brush handles dropped on the rim).

Pros

• Philippe Starck design pedigree in a two-piece form factor — rare and meaningfully different from mainstream two-piece toilets
• Standard 12-inch rough-in fits most US homes without re-plumbing
• HygieneFlush rimless bowl for superior cleanliness vs. traditional rim-cavity designs
• Premium ceramic finish quality consistent with Duravit's broader catalog
• Optional WonderGliss and HygieneGlaze upgrades for specific use cases
• Lower price than Starck 2 one-piece or wall-hung Duravit options

Cons

• Higher price than mainstream US two-piece toilets ($799-$1,099 vs. Kohler Cimarron $349-$449)
• 5-year china warranty weaker than Kohler lifetime china at lower price point
• Seat sold separately — adds $189-$269 to total cost
• Limited US dealer network — must source through Ferguson, Build.com, or specialty plumbing retailers
• Less aesthetic refinement than Starck 2 one-piece or wall-hung Duravit Starck options
• Tank-to-bowl gasket and mounting bolts are wear points over 10+ year service life (typical for all two-piece toilets)

Who Should Specify Starck 3

• Renovations requiring two-piece form factor (existing 12-inch rough-in, no in-wall plumbing rework planned)
• Buyers wanting Philippe Starck design language but constrained by rough-in geometry
• Premium bathroom renovations with $15,000-$25,000 total budget where toilet is one of multiple Duravit-specified fixtures
• Architects specifying Duravit ecosystem across multiple bathrooms where some require two-piece and others one-piece or wall-hung
