The Toto Aquia IV Washlet+ Elongated Skirted Toilet Bowl with Cefiontect is designed for use with the Aquia IV tank. The skirted design conceals the trap way, which enhances the elegant look of the toilet and adds an additional level of sophistication.

When paired with its tank, the Aquia IV features TOTO's Dynamax Tornado Flush®, utilizing a 360-degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT®, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces.

The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The Aquia IV bowl offers TOTO T40 Washlet®+ compatibility for when you are ready to upgrade. Compatible with T40 Washlet®+ electronic bidet seat models only. The Washlet®+ toilet features a channel on the bowl surface to help conceal your Washlet®+ supply line and power cord for seamless integration. When paired with its tank, the Aquia IV meets the standards for EPA WaterSense, and California CEC and CALGreen requirements. The Aquia IV comes ready for installation into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter.

I love this toilet. I had to order the bowl from Wayfair bc it arrived in broken pieces bc the first vendor didn’t package it properly. This was packaged very well and arrived in perfect condition. Highly recommend Wayfair and this product. Anonymous. Fort Lauderdale, FL. Wed Aug 27 2025

Arrived quickly and it looks great! I will update my review once it’s installed.. Kimberlyn. US. Mon May 17 2021

Better service and quality than buying a your local shop! :). Viviana. US. Mon Apr 03 2023
