Corbelle® Tall two-piece elongated toilet with skirted trapway, 1.28 gpf

Corbelle® Tall two-piece elongated toilet with skirted trapway, 1.28 gpf

The Corbelle Tall two-piece elongated toilet is 2-1/2" taller than Comfort Height® toilets to provide ultimate accessibility and ease of use. Corbelle Tall delivers a powerful swirling flush with Revolution 360® flushing technology to keep your bowl clean longer than a conventional flush.
