A quick note about Toto model numbers: "Eco" versions of Toto toilets have the same model number as the original version, but will have an "E" somewhere after the number. The only difference between the original and "Eco" versions is the amount of water they flush (1.6gpf vs 1.28gpf) - thus, they use a different flush valve and/or a different flapper. The other internal components will typically be the same. Any internal differences will be noted on the product page.

Additionally, be aware that on occasion Toto has changed the NAME of certain lines, but the model number remains the same. For example, the Gwyneth one-piece is now the Ultramax II and the Gwyneth two-piece is now the Drake II. We have provided the most current names to better assist our customers, but please refer primarily to model NUMBER when selecting your toilet parts to ensure you're getting the right parts for your model.

If you are uncertain about what your model number is, please refer to our FAQs or contact us for additional assistance.

Frequently Asked Questions

Q. "How can I find the model number and color of my Toto toilet?"
A. Look inside your tank. Always exercise caution when removing the tank lid, as it is fragile and can be easily broken if stepped on or dropped. Inside your tank on the back wall of the tank or sometimes on the right hand wall (opposite the trip lever), you will see a model number stamped or engraved in the porcelain. Typically, for Toto toilets, you will see letters with a three-digit number. There may be more letters following, depending on additional features available on that model of the toilet. Elsewhere in your toilet tank, you will find a color code. Color codes start with a # followed by a two-digit number. The most common Toto colors are #01 - Cotton White, #03 - Bone, #04 - Gray, #11 - Colonial White, #12 - Sedona Beige, and #51 - Ebony.

How to find Toto toilet model number and color code

Q. "I didn't see any water saving eco-friendly toilet tank conversion parts on your site and was wondering if you might add them in the future?"
A. There are many so called eco-friendly products on the market. However, eco-friendly does not necessarily mean user friendly. In our opinion, we have not found one that is user friendly. Toilets are designed to flush with a set water usage and that is why the federal government passed a law in the 1990's that all new toilets made must flush using 1.6 gallons of water or less. Once the waste is flushed from the toilet, a certain amount of water is still needed to push the waste down the drain line to the sewer or septic tank.

Most "eco-friendly" conversion devices we have seen allow the user to flush a toilet at two levels. Some are called dual-flush, meaning one level is set higher to allow a lesser amount of water to be flushed into the bowl, and the other lower level to allow a full flush when needed. The one set higher will not necessarily flush the water in the bowl, but can dilute it. Not eco-friendly in our minds if it is not sanitary.

If you have to flush a toilet twice to get the water in the toilet to flush completely out, then it is not "eco-friendly", and possibly should be replaced with a toilet that is designed to use less water and still flush properly. Possibly in the future, if someone designs a tank coversion product that is both eco-friendly and sanitary, then we would certainly consider offering that product. However, we do offer parts for certain brands of dual-flush and/or eco-friendly toilets. These toilets were specifically engineered to use the lesser amounts of water and maintain sanitary conditions, and so are very different from standard toilets with an "eco-friendly" conversion kit installed.
