Gerber av-21-852-25 Round Front Toilet Bowl 1.28/1.6 Gpf

Product Description

The GERBER av-21-852-25 is a round front toilet bowl from the Avalanche series, designed for residential bathroom installations where water efficiency and reliable flush performance are required. This bowl supports a dual-flush configuration rated at 1.28 and 1.6 gallons per flush (GPF), meeting WaterSense criteria at the lower flush volume. Finished in Bone, it is intended for use as a replacement or new-installation bowl and is installed by licensed plumbers or qualified trades working on residential bathroom fixtures. The bowl ships at 53 pounds and requires a matched tank for complete toilet assembly.

The av-21-852-25 is suited for residential bathroom applications where a compact round front footprint is preferred over an elongated bowl profile. The dual-flush 1.28/1.6 GPF rating makes it appropriate for installations in jurisdictions with low-consumption plumbing requirements. The Bone finish coordinates with standard trim and fixture color lines in that finish family. This bowl is sold as a standalone component and requires a compatible Gerber Avalanche tank to complete the toilet assembly.

Compatibility

Installation Notes

Installation of this toilet bowl should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and flush the existing toilet to drain the tank and bowl before beginning any removal or installation work. Use a new wax ring or wax-free seal appropriate for the floor flange height, and verify bolt spacing before setting the bowl. Do not overtighten closet bolts, as this can crack the vitreous china.
