10 Best Dual Flush Toilets 2025 in the United States

The Kohler K-5401-PA-0 Veil Comfort Height Skirted One-Piece Elongated Dual-Flush Intelligent toilet offers a mix of advanced features and modern design. It stands out with its dual-flush technology, allowing users to choose between a full or partial flush, which can be cost-effective and environmentally friendly. The elongated bowl shape and chair-height seating provide comfort, while the tankless design and integrated personal cleansing system give it a sleek, minimalist look.

The toilet also boasts a variety of high-tech features, such as a motion-activated lid, LED lighting, a heated seat with adjustable temperature, and a touch-screen LCD remote control for ease of use. Additionally, the self-cleaning function with UV light and electrolyzed water maintains hygiene, and the emergency flush function ensures usability during power outages. Installation is relatively straightforward with standard rough-in requirements and included accessories.

However, some potential drawbacks include its high price point and the reliance on electricity for many of its features, which may be a concern during power outages despite the emergency flush capability. Additionally, its complex features might require a learning curve for some users. This toilet is best suited for those looking for a high-end, technologically advanced toilet with a focus on comfort and modern aesthetics.

The Kohler Leap One-Piece Smart Toilet is designed for those looking for a modern, high-tech dual-flush toilet with added bidet functions. It offers two flush options (1.0 and 1.28 gallons per flush), helping to save water while maintaining effective waste removal. The elongated bowl shape provides extra comfort compared to standard round bowls, and the comfort height (around standard chair height) makes sitting and standing easier for most adults. Its fully skirted trapway means the sides are smooth, which helps keep cleaning simple and neat. Installation is floor-mounted, which is the most common type and should fit most bathrooms. The toilet’s material is plastic with a white finish that matches typical bathroom styles, although plastic might not feel as premium as ceramic for some.

Unique to this model is the integrated bidet with adjustable spray settings, warm water, and self-cleaning features, including UV wand cleansing and hands-free lid operation, adding convenience and hygiene. The Quiet-Close lid prevents loud slamming, which is a nice touch. The toilet is quite heavy (over 100 pounds), which might make installation more challenging without professional help. Also, while the smart bidet features are advanced, they might be more than some users need or want, possibly increasing the price and maintenance complexity.

For those seeking a sleek, all-in-one toilet with water-saving flush options and integrated personal cleansing, this model fits well. However, those looking for a simpler or more budget-friendly option may find it more than necessary.

The HOROW T0338W One Piece Toilet is a solid option if you're looking for a dual-flush toilet. One of its main advantages is the dual flush system, offering both 0.8 and 1.28 gallons per flush, which is efficient and water-saving. The elongated bowl design provides comfort, and the chair height of 17.3 inches makes it ADA compliant, making it easier for elderly and disabled individuals to use.

The fully-glazed 2-inch trapway ensures powerful flushing, with a high MAP score of 1000 grams, ensuring waste is cleared effectively. The porcelain material and white finish offer a sleek and modern look, and the slow-close seat adds to the quality, reducing noise and wear over time. Installation is simplified with big opening holes on the sides, and the provided components and instructions make it accessible even for non-professionals, though a plumber might still be necessary for some users.

Weighing in at 99 pounds, the toilet is quite heavy, which might make handling and installation a bit challenging. Also, it has a 10-inch rough-in, which is somewhat less common and might limit compatibility with existing plumbing setups. Despite these minor drawbacks, this toilet performs well and is especially suited for those needing an ADA-compliant and water-efficient option.
