The best dual flush elongated toilet depends on whether you prioritize a compact one-piece design, chair-height seating, a lower-water flush option, or a complete installation package. The Gerber Maxwell is a two-piece option with a soft-close seat; DeerValley and HOROW models add chair-height comfort; American Standard offers a simple push-button choice; and Swiss Madison features a vortex-style flush.

The Gerber Maxwell Select is best for buyers who want a straightforward two-piece toilet with two flush-volume choices. Its split-flush mechanism uses 1.0 or 1.28 gallons per flush, and the listed features describe it as a high-efficiency model designed for bowl-clearing performance.

An elongated slow-close seat is included, which helps prevent slamming and noise. Its two-piece construction may suit shoppers who prefer that configuration over a seamless one-piece toilet. Choose this model if the listed flush rates and included seat match your priorities.

Limitation: The provided product details do not list the toilet’s overall dimensions or rough-in measurement, so verify fit before ordering.

The dual-flush system offers 1.0 and 1.28 GPF options. Product details also specify dual nozzles and a 1000g MaP score. Its rimless bowl and seamless one-piece build are features to consider if an uncluttered exterior is a priority.

Its dual flush uses 1.1 or 1.6 GPF. The product information also lists siphon flushing and a fully glazed 2-inch trapway. Choose it if those flush specifications and compact dimensions suit your bathroom.

Buying Guide: How To Choose A Dual Flush Elongated Toilet

Which flush rate should you compare?

Check both numbers in the dual-flush rating. The lower figure generally identifies the reduced-volume option, while the higher figure is the other flush setting. In this selection, rates range from 0.92/1.28 GPF to 1.1/1.6 GPF. Compare the complete pair rather than relying only on a “water-saving” label.

Should you choose one-piece or two-piece?

A one-piece toilet has a seamless body, while a two-piece toilet has a separate tank and bowl. The products here include both configurations. Consider the design you prefer and compare the listed dimensions. Do not assume that one construction type will fit a particular bathroom without checking measurements.

What does chair height mean for comfort?

Seat height affects how high or low you sit. Several listed models specify heights from 17.3 to 17.5 inches, and the DeerValley and HOROW details describe chair-height seating. Compare the stated measurement with the needs of household members, and check whether the number refers to the seat or another part of the toilet.

How do you check installation fit?

Measure the rough-in, typically the distance from the finished wall to the center of the floor drain, and compare it with the toilet specifications. The Swiss Madison and BAYROLL listings specify a 12-inch rough-in, but not every product description here provides that measurement. Also verify overall depth, width, plumbing access, and included installation parts.
