The TOTO NEOREST WX2 Dual Flush 1.2 or 0.8 GPF Wall-Hung Toilet Bowl Unit is designed for use with the NEOREST AC Top Unit and NEROEST In-Wall Tank Unit. The NEOREST AC bowl features a sleek, skirted bowl, which makes for easier cleaning and provides a modern look. The NEOREST in-wall tank unit will conserve space in your bathroom and allows you to adjust the rim height between 15 and 19 inches from the floor. The CEFIONTECT(R) glaze minimizes waste from sticking to the ceramic. The NEOREST AC bowl features TOTO's 3D Tornado Flush(TM), a hole-free rim design featuring three powerful nozzles that generate a centrifugal, cyclonic rinsing action. The dual flush function will effectively remove waste with only 0.8 or 1.2 gallons per flush. Includes bowl unit only. For use only with separately sold NEOREST WX2 SN9548MX top and WT175MA in-wall tank unit.
