Gerber he-21-538 Logan Square Elongated Toilet Bowl

Product Description

The GERBER he-21-538 is a floor-mount elongated toilet bowl from the Logan Square series, constructed from vitreous china in a White finish. Designed for residential and light commercial plumbing installations, this bowl features a siphon jet flush action rated at 1.28 gallons per flush, meeting WaterSense-class efficiency standards. The elongated bowl shape and standard 12-inch rough-in make it a straightforward specification for new construction and replacement projects alike. A licensed plumber or experienced installer handles the rough-in, connection, and final set. Seat is not included and must be specified separately.

The he-21-538 is suited for residential bathrooms and light commercial restrooms where a floor-mount elongated bowl is required. It pairs with a separately supplied tank and flush valve assembly. The 12-inch rough-in dimension is the most common residential specification in North American construction, making this bowl broadly applicable across typical bathroom configurations. When specifying for a full toilet assembly, confirm tank compatibility with your distributor before ordering.

Compatibility

Designed as a floor-mount elongated toilet bowl replacement or new-installation component within the GERBER Logan Square series. Requires a compatible tank, supply line, wax ring, floor bolts, and separately purchased toilet seat for a complete installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and drain the existing toilet completely before removing a prior unit. Set the bowl onto a wax ring or wax-free seal aligned to the floor flange, and secure with closet bolts — do not overtighten the nuts against the vitreous china base, as this can crack the bowl. Connect the tank per manufacturer instructions before restoring water supply and testing for leaks.
