Our take on the TOTO Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Universal Height Toilet

The TOTO Aquia IV is a two-piece elongated toilet with a dual flush: 1.28 gallons for solids and 0.9 gallons for liquids. It uses TOTO's Dynamax Tornado Flush, which jets water around the rim for a quieter, more thorough rinse than gravity-fed rivals. The soft-close seat is included, and the bowl is WASHLET+ ready for a later bidet seat upgrade. It suits remodelers who want a slim, contemporary skirted look and water savings without stepping up to a one-piece. Owners like the flush and the low profile, but some report weak flush performance and fit issues, and the 3.8 rating reflects that split.

Questions and answers

Does the Aquia IV come with a seat?
Yes. A soft-close elongated seat and cover are included, so you do not need to buy one separately.
Can I add a TOTO WASHLET to this toilet?
Yes. The bowl is WASHLET+ compatible, so a compatible bidet seat can be added later without exposed cords or hoses.
What rough-in does it need?
It uses a standard 12-inch rough-in and mounts on the floor. Measure from the finished wall to the drain center before buying.
How much water does each flush use?
The full flush uses 1.28 gallons and the light flush uses 0.9 gallons, selected with the dual-flush buttons.
Is it a one-piece or two-piece toilet?
It is a two-piece: the tank and bowl are separate. That makes it lighter to move but adds a seam to clean compared with a one-piece.
Is the Aquia IV good for a small bathroom?
It is fairly compact at 15.5 inches wide and 27.6 inches deep, with a slim tank, so it fits many smaller bathrooms.
