Frequently Asked Questions

What if my order arrives damaged?
While we take great care in the packaging and handling of orders, we ask that customers inspect all shipments within 48 hours of delivery, and in the rare event that your order arrives damaged, please send us an email with a photo showing the damages (so we can file a claim with the carrier), and let us know whether you prefer a free replacement or a refund.

Why do you ask for phone numbers during checkout?
Some shipping carriers, especially those handling freight, require a phone number to coordinate your delivery. We respect your privacy and guarantee that any information you provide will never be shared with third parties, except for shipping purposes.

The TOTO Aquia IV Cube Dual Flush 1.28 and 0.9 GPF Auto Flush Compatible Toilet Tank is designed for use with the Aquia IV dual flush bowl. The smooth rectangle shape offers a modern and sleek design to complete your bathroom. Features TOTO's Dual-Max dual flush option, allowing you to proactively conserve water usage, allowing you to choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs.

This version of the Aquia tank offers TOTO T40 WASHLET+ and Auto Flush compatibility for when you are ready to upgrade to a hands-free flush system with electronic bidet seat. The Aquia IV Cube tank meets the standards for EPA WaterSense, and California's CEC and CALGreen requirements.
