Easy-Clean Glaze

The CEFIONTECT glaze creates an extraordinarily smooth ceramic surface that helps keep the bowl clean. By preventing debris and mold from adhering to the porcelain, it ensures that routine bathroom maintenance requires less time and effort. A common feature in Toto Two Piece Toilets.

Powerful Tornado Flush

The TORNADO FLUSH system utilizes two powerful nozzles to create a centrifugal, cyclonic rinsing action with an ultra-low 1.0 GPF volume. It delivers a strong and efficient clean with every flush, sweeping away waste efficiently.

Frequently asked questions about the TOTO Glaston 1G MW4723346CUFG

What is the primary difference between the Glaston two-piece model and a one-piece skirted toilet?

The Glaston features a separate tank and bowl that are bolted together during installation. This two-piece configuration can make delivery and maneuvering into small spaces easier since the weight is split across two individual pieces, while still offering the premium look of a fully skirted base once assembled.

What makes a WASHLET+ toilet different from standard bidet seat installations?

Standard bidet seats leave external water hoses and electrical cords exposed on the side of the bowl. A TOTO WASHLET+ toilet features a dedicated internal channel molded into the porcelain body, allowing the bidet lines to pass directly through the toilet base for a completely hidden, seamless look.

Can I add an Auto Flush feature to any of the bidet seat options?

No, the convenient Auto Flush upgrade option is exclusively available if you customize this system using either the premium WASHLET S7 or WASHLET S7A bidet seat configurations.
