TOTO Drake Two-Piece Elongated 1.6 GPF
The TOTO Drake 1.6 GPF model uses a Tornado Flush system that swirls water to thoroughly rinse the bowl surface. CEFIONTECT glaze helps prevent waste buildup, making cleaning easier. Its universal height supports easier seating and standing for a wide range of users, with ADA compatibility in mind. Best for households prioritizing strong one-flush performance while saving water without compromise. Caution: Some users may prefer a softer water-sound profile and the 1.6 GPF can still feel more aggressive than lower-flow options.
TOTO Drake 1.28 GPF MS776124CEG
This Drake model reduces water use to 1.28 GPF while maintaining robust flushing thanks to a wide three-inch flush valve and siphon jet bowl. The design leans toward a modern aesthetic and fits standard 12-inch rough-ins. Best for homes prioritizing WaterSense-certified efficiency with a contemporary look. Consider this if you want strong, reliable performance with lower water per flush. Caution: Dual-flush performance depends on installation accuracy and line pressure.
Gerber Maxwell Select Dual-Flush
The Gerber Maxwell Select offers a versatile dual-flush mechanism with a choice between 1.28 GPF and 1.0 GPF. Its two-piece, soft-close seat setup supports quiet operation, and its modern styling blends with many decors. Best for budget-conscious buyers who want dual-flush efficiency with straightforward maintenance. Choose this if you value a practical, quiet, two-flush solution; avoid if you need higher-than-1.28 GPF performance in a single flush under heavy waste conditions.
DeerValley ADA Comfort Height Two-Piece
This DeerValley model emphasizes ADA-compliant comfort with a 17 13/16-inch seating height and a quiet, soft-close seat. The 360-degree jet ensures a thorough clean while conserving water with a dual-flush option. Best for accessibility-focused bathrooms and users who value ease of use and quiet operation. Limitation: Some installations may require additional components for optimal dual-flush alignment.
Gerber Viper Force Elongated Two-Piece
The Gerber Viper Force features a 1.28 GPF high-efficiency flush with a soft-close elongated seat for quiet, convenient use. This two-piece model blends modern design with practical dual-flush functionality. Best for bathrooms that need a reliable, space-saving option with simple maintenance. Caution: If you frequently have very heavy waste, a higher flush option (like 1.6 GPF) may be more forgiving in a single flush.
DeerValley Elongated One-Piece ADA DV-1F0437
Although a one-piece model, this DeerValley offers an ADA-compliant chair-height seat with a rimless bowl design. Dual-flush capability ranges from 1 to 1.28 GPF, delivering reliable performance while prioritizing water efficiency. Best for users seeking a compact, integrated look with accessible height. Limitation: Rimless bowls can be less forgiving for some cleaning routines compared with traditional rims.
Buying Guide: Key Purchase Considerations
- Flush options and water use: Decide between 1.0–1.28 GPF for maximum efficiency or 1.6 GPF for extra power in a single flush. Consider your household’s typical waste load and local water restrictions.
- Height and accessibility: ADA-compliant and comfort-height toilets reduce strain for seated users and those with mobility concerns. Measure rough-in and seat height to ensure a proper fit.
- Flushing technology: Tornado or dual-flush mechanisms can impact cleaning performance and noise. Look for siphon jet designs and smooth rims for consistent results.
- Seat type and closing action: Soft-close seats prevent slamming and are often included; verify whether the seat is included and if replacement parts are readily available.
- Installation considerations: Some models require standard 12-inch rough-ins; others may differ. Check compatibility with your bathroom layout and existing plumbing.
- Maintenance and glaze: Glazes like CEFIONTECT reduce waste buildup, simplifying cleaning. Consider glaze durability and ease of replacement.
