Gerber gmx21958 Round Front Ergoheight Toilet Bowl White

Product Description

The GERBER gmx21958 is a two-piece, round front, ErgoHeight toilet bowl in white vitreous china, designed for residential bathroom installations where space efficiency and reliable performance are priorities. The bowl pairs with a separate tank and features a 3-inch flush valve, a dual-fed siphon jet flushing action, and a large 2-inch fully glazed trapway engineered to minimize clogs. With a WaterSense-certified flush rate of 1.28 gallons per flush, this bowl is part of a high-efficiency toilet system that delivers a 1,000-gram MaP score. Installation is handled by licensed plumbers working on new construction or retrofit projects.

This bowl fits the Maxwell collection and accommodates a 10-inch rough-in, making it suited for standard residential bathroom configurations. The ErgoHeight bowl height meets ADA requirements, providing easier sitting and standing access for a wide range of users. The round front profile is well matched to smaller bathroom footprints where an elongated bowl would not fit. The toilet seat is not included and must be sourced separately. This bowl is intended for use as part of a complete two-piece toilet assembly.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code where applicable. Shut off the water supply and flush the existing toilet to drain the tank and bowl before beginning any work. The multi-point tank-to-bowl mounting system is tool-free and uses stainless steel bolts, rubber channel pads, and double-wing nuts for a secure seal. Confirm rough-in measurement before installation to verify proper fit.
