This American Standard H2Option® Two-Piece Dual Flush toilet performs well with strong flushes and its narrow width is a plus. Installation was straightforward. However, I was disappointed that the included insulation liner doesn't completely cover the bottom of the tank. This results in the portion of the tank that overhangs the bowl still experiencing condensation and sweating. Tanker18. Seaside, OR. Wed Jan 22 2025
