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.
• What about the seat height?
Most standard toilets are 16-17 inches from the floor to the top of the seat, or about 15 inches to the bowl rim. Universal height (or comfort height) toilets, like the one you're looking at, are roughly an inch taller—around 16 inches from the floor to the bowl rim, or 17-18 inches to the seat. Universal height toilets are designed to provide greater comfort for a wider range of users, making it easier to sit and stand, especially for older adults. Keep in mind that while universal height is one of the requirements for ADA compliance, other factors also come into play.
• Is the seat included?
Yes, this toilet includes the original TOTO SoftClose toilet seat.
• Will I regret not choosing a toilet with a higher flush volume?
Unlikely. TOTO has been working on flushing technologies as if their livelihood depends on it – and in some places, it does. The truth is, it's more about engineering than just volume – think of a car with a smaller engine that can go faster than one with a larger one. TOTO's Tornado Flush technology uses 3-inch flush valves (instead of traditional flappers) to force water into dual nozzles, creating powerful cyclonic rinsing action. This causes the water to spin in a vortex inside the bowl, making sure every part of it is thoroughly cleaned. The pressure from the nozzles improves both cleansing and bowl evacuation. Other innovations include fully glazed, extra-smooth trapways that prevent debris from sticking, extra-large siphon jets, and seamless, concave rim designs – all working together to make this toilet's flush more than enough for jobs of all magnitudes.
• What is this Washlet+ stuff?
This toilet is Washlet+ compatible. Washlet+ compatible toilets have a special channel (a strategically placed hole) on the bowl surface to help conceal a bidet seat's supply line and power cord for a cleaner look. Other than that, it functions as a standard toilet, and you can use it without a washlet. A washlet will also work with a non-Washlet+ toilet, but the wires will be visible.
The Aquia IV is a sleek, modern one-piece toilet that combines style with serious performance. It uses TOTO's DYNAMAX TORNADO FLUSH technology to deliver a powerful clean while using less water – 1.28 GPF for full flushes and 0.9 GPF for liquid waste.
The elongated bowl fits universal height installations, and it comes with a matching soft-close seat already included. The skirted design hides the trapway for a cleaner look and easier maintenance. What really sets this toilet apart is the CeFiONtect ceramic glaze, which creates a super-smooth surface that resists stains and buildup, so you'll spend less time scrubbing. Plus, it's Washlet+ ready, so you can add a Washlet bidet seat whenever you want. Bone finish.
Universal Height offers sinks and toilets at a more manageable height, making the bathroom more accessible and enjoyable for everyone. This simple design principle allows all people, from the beginning of their days through the rest of their lives, to completely enjoy their bathroom experience, regardless of age or ability.
