    One-Piece Toilets — Sleek & Seamless Designs

    Explore our curated collection of one-piece toilets at Dupont Kitchen & Bath — combining tank and bowl into a clean, seamless design that’s easier to maintain. Choose from a variety of shapes, heights, and smart technologies to suit your bathroom.


    Shapes, Heights & Styles

    • Elongated vs Round vs Compact Elongated — elongated often offers greater comfort; round is better for tighter spaces.

    • Comfort Height vs Standard — comfort height (chair height) is easier to sit and stand from.

    • Skirted / Concealed Trapway — makes surfaces easier to wipe clean.


    Features & Technology

    • Water Smart / Dual-Flush Options — use less water on partial flushes.

    • Anti-Bacterial Glazing — resists bacteria and simplifies cleaning.

    • Integrated Smart Toilet Combos (for example, from StoneTouch’s IKLEEN line) combining one-piece structure with advanced washlet functions.

    • Lead Time & Stock — filters show items in revolving stock, or with lead times of 4–7 days, 2–3 weeks, etc.


    Installation & Compatibility Tips

    • Confirm rough-in depth (commonly 12", but may vary).

    • Check for clearance behind and around the unit for plumbing access.

    • Smart toilets need GFCI-protected power nearby.

    • For heavy one-piece units, ensure floor & mounting hardware are adequate.
