TOTO Introduces the Aquia IV® Arc and Aquia IV Cube

Company Extends Popular Aquia IV Dual-Flush Product Line with New WASHLET®+ and Toilet Designs

(Morrow, GA) December 14, 2020 — TOTO, the world’s largest plumbing manufacturer with more than $5.47 billion in annual sales, announced today that it will extend its much sought-after Aquia IV Dual Flush Toilet line.

Aquia IV Cube Toilet

The company is adding its new Aquia IV Arc and Aquia IV Cube designs, which are available as WASHLET+ models or floor-mount toilets.

Design: Global developments in architecture, design, and lifestyle trends inspire TOTO’s design philosophy. The new Aquia IV Arc and Aquia IV Cube designs will be welcome additions to any bath space.

The Aquia IV Cube provides a fashionable contemporary design with its boldly geometric tank. In turn, the Aquia IV Arc offers a sophisticated transitional design statement with its elegant flared tank. Both models’ elongated skirted design is aesthetically pleasing and offers easy cleaning by removing the nooks and crannies where dust collects, while their slender tank gives them a heightened sensibility.

Like their handsome predecessors, the new Aquia IV Arc and Aquia IV Cube are Universal Height, TOTO’s ergonomic, comfortable height design that facilitates rising from a sitting to standing position. These aesthetically-pleasing toilets are ADA height compliant with their SoftClose® Seat or WASHLET.

CLEANOVATION: TOTO articulates its philosophy of clean innovation technology as CLEANOVATION. TOTO believes that cleanliness is a fundamental human value that enriches beauty, peace of mind, feeling refreshed, consideration for the environment, and wellness. TOTO uncompromisingly pursues innovation that brings to market cleanliness technologies that enhance consumers’ daily lives.

WASHLET+ Concealed Connection

WASHLET+ Design: The Aquia IV Arc and Aquia IV Cube toilets seamlessly connect with their WASHLET+ models, leaving no protruding supply connections (water or electrical). This TOTO innovation -- called WASHLET+ -- improves the units’ appearance and enhances their cleanliness by inhibiting dust and dirt buildup. With the WASHLET+ connection structure, WASHLET+ models easily detach from the Aquia IV Arc and Aquia IV Cube toilet, so consumers can reach areas where dust and dirt tend to collect. This design innovation is just one way TOTO makes it easier to keep the Aquia IV Arc WASHLET+ Toilet and Aquia IV Cube WASHLET+ Toilets cleaner longer.

Flushing Performance: The Aquia IV Arc and Aquia IV Cube WASHLET+ Toilets offer the DYNAMAX TORNADO FLUSH® system by TOTO, which features two powerful nozzles that create a centrifugal, cyclonic rinsing action that reduces waste buildup and keeps the bowl cleaner. Using only 1.28 or 1.0 gallons per flush (gpf) for the full flush and 0.8 gpf for the light, this high-efficiency flushing system is more effective in one flush than most toilets are with multiple flushes. Its modern, seamless concave rim design means that these high-efficiency toilets perform more consistently and are easy to clean.

Clean Synergy: TOTO coined the term “Clean Synergy” to describe the interplay of its PREMIST®, DYNAMAX TORNADO FLUSH, CEFIONTECT®, and EWATER+® bowl cleaning technologies, all of which are only available from TOTO.

  • PREMIST: The bowl’s interior is sprayed with a fine mist of water to reduce matter’s ability to stick to its surface.
  • CEFIONTECT:This nano-technology glaze by TOTO seals the porcelain with an ionized barrier, creating a super-slippery, non-porous surface that repels matter, mold, and mildew.
  • DYNAMAX TORNADO FLUSH System: A TOTO innovation, the rimless bowl design and 2.5-inch diameter trapway use 100% of the water to remove waste effectively and clean every inch of the bowl and rim. The company’s DYNAMAX TORNADO FLUSH System optimizes water conservation while setting a high bar in quiet world-class flushing performance.
  • EWATER+: The bowl’s surface and WASHLET wand’s cleanliness is ensured by automatically spraying them with EWATER+. EWATER+ uses no chemicals or cleaning agents, providing peace of mind every day that microscopic buildup has no place to hide.

Auto-Flush: The new Aquia IV Arc and Aquia IV Cube WASHLET+ Toilets and Aquia IV Cube WASHLET+ offer Auto-Flush, a sensor-operated, hands-free flush feature. The company’s proven touchless technology enables the toilet to flush automatically when the user simply rises and walks away. There is no need to wave a hand over a sensor to activate it; the unit responds automatically. Users may also manually flush the unit if they desire by using the toilet’s push plate panel.

Aquia IV Arc Toilet

Sustainability:Beneath their sophisticated contemporary exteriors, the Aquia IV Arc WASHLET+ Toilet and Aquia IV Cube WASHLET+ Toilets’ matchless DYNAMAX TORNADO FLUSH system delivers an unparalleled flush that clears the bowl the first time, every time using a mere 0.8 gpf (light flush) or 1.28 or 1.0 gpf (full flush). The company’s market-leading DYNAMAX TORNADO FLUSH system is more effective in one flush than most toilets are with multiple flushes.
