  • The TOTO Eco Promenade Two-Piece Round 1.28 GPF Universal Height Toilet is a high profile, traditionally designed toilet. The Eco Promenade bowl and tank set includes a tank to bowl gasket, tank to bowl hardware, and toilet bolt caps. The Eco Promenade utilizes TOTO''s E-max flushing system, featuring a 3'' wide flush valve, extra-large siphon jet, and a large trapway. This reliable, highly efficient combination generates a powerful cleansing flush while only using 1.28 gallons of water. The Eco Promenade is designed to feature TOTO’s Universal Height which allows for a more comfortable seat position across a wide range of users. The Eco Promenade features a decorative chrome trip lever on the left-hand side of the tank. The Eco Promenade is ADA compliant and meets the standards for EPA WaterSense, and California’s CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, and toilet seat.

About TOTO:

At TOTO, we’ve always been inspired by a desire to improve everyone’s quality of life. Through almost a century rich with innovation, TOTO has changed the perception of what a bathroom can be — and how it can be used.

Our founder, Kazuchika Okura, had a vision more than one hundred years ago in 1912, before the concept of public sewage systems was widespread in Japan. After seeing more advanced systems overseas, he was moved to establish a ceramic sanitary ware laboratory to develop healthier and cleaner living spaces.

In 1917, Okura founded Toyo Toki K.K. (which became known as TOTO LTD.) to supply the market with these products. TOTO was founded on a commitment to provide a comfortable living space for people, while always protecting the planet and its water.

Japan’s rich artistic heritage in pottery and porcelain is alive in every TOTO product we create today. Throughout our expansion worldwide, TOTO has remained true to the Japanese traditions that have shaped our Company Motto and Philosophy.

TOTO has always embraced technology, pursued the highest levels of cleanliness, incorporated high aesthetic standards, protected the environment, and worked to improve people’s lifestyles. Because we continually innovate in all of these areas, TOTO has become the world standard of excellence for a quality bathroom experience.
