Mansfield 4115-3106 Barrett SmartHeight Elongated Two-Piece Toilet – 1.28 GPF

Brand: Mansfield Plumbing | SKU: 4115-3106

Product Overview

The Mansfield 4115-3106 Barrett combines an elongated bowl, SmartHeight seating height and a 1.28 GPF high-efficiency flush in a two-piece toilet designed for a standard 12-inch rough-in. The taller SmartHeight format can make sitting down and standing up easier for many users, while the elongated bowl provides additional front-to-back seating room compared with a round-front design.

A concealed trapway gives the base a cleaner appearance and reduces exposed contours around the discharge path, making routine exterior cleaning easier. Mansfield specifies its MagnaFlush flushing system with a 3-inch flush valve for this configuration, along with a 2-1/8-inch trap diameter and 800-gram MaP rating. The toilet is WaterSense certified and ADA compliant when installed according to applicable requirements. A toilet seat and water-supply line are not included.
