One-Piece Elongated Toilet- Toto Ultramax Reviews

The flushing toilet is easy to install as it comes with a 12-inch rough-in. It also weighs 93 lbs with 28 x 17 x 28 inches measurements. Being a 1-piece toilet design, it is quite heavy, and you will need help installing it. Check the user manual to help guide you during installation. Alternatively, you can hire a professional plumber to install the toilet. Here are the features-

Quality and design

Toto has made a stride when it comes to durability. Past users of the Toto Ultramax one-piece toilet highly applaud it for its outstanding durability. Made of vitreous china material, this is a toilet that will last for more than 20 years. Thus, it is a great investment, and you won’t have to purchase or replace it with any other toilet anytime soon.

Apart from that, the Ultramax one-piece toilet is a stylishly designed toilet with a seat included. Unlike some Toto toilet models, you won’t have to buy the seat separately. Another outstanding feature of this toilet is its SanGloss finish, which gives it a sleek and sparkling look. With the vitreous china material, this is a toilet that you can count on to use for a longer period of time.

Toto Ultramax Has a Powerful Flushing System

If you’re tired of flushing your toilet more than once for it to clear the contents in the bowl, then the Toto Ultramax toilet will be a great option for you. The G-max flushing mechanism is the industry benchmark for flushing performance. It will clear both solid and liquid wastes in just one flush and leave the toilet sparkling clean. It can be used as a commercial toilet because of its powerful flush.

This is all thanks to the larger 2.125-inch glazed Trapway that provides increased flow, drawing water into the bowl faster and then away with greater force to avoid clogging. In addition to the larger Trapway, the toilet comes with a 3-inch flush valve that creates a quicker, quieter, and more forceful flush that clears all the waste in the bowl. The extra-large siphon jet creates great power for one-flush superiority to ensure that what is pushed down remains down.

Easy to clean

The Toto Ultramax self-cleaning toilet not only features a powerful flushing mechanism but is also easy to clean. The powerful siphon jet clears contents in just one flush, leaving the toilet clean and without dirt.

The SanaGloss ion barrier also plays a major role in keeping the toilet clear as well. It makes sure that nothing sticks on the toilet after every flush. Moreover, it makes the toilet look sparkling clean, so you’ll not have to scrub your toilet hard to remove stains and dirt. Being a one-piece toilet, cleaning the entire toilet will be swift as there are no hard-to-reach areas.

Sleek and Comfortable

Whether your bathroom is of modern or traditional design, this toilet will still fit in perfectly. The Ultramax one-piece toilet is excellently constructed with a sleek design. It is easy to fit in the bathroom as it has a 12-inch rough-in. In addition, the elongated bowl design provides enough sitting space for users.

The manufacturer offers a variety of colors to pick from, which include bone, cotton white, colonial white, and Sedona beige. Most people prefer cotton white because it easily matches most interior décor.

SoftClose seat included

The days of banging or slamming the toilet seat are over. The Ultramax toilet has simplified things for its users as it has a SoftClose. After using the toilet, the seat will close slowly without slamming. The seat and lid use a built-in SoftClose hinge system, slowly and quietly lowering the seat to the bowl.

N:B: The updated version is Toto UltraMax II which has a powerful double cyclone flushing system.

If you’ve kids at home, this may not be the best toilet to install, as the toilet seat may need to be replaced almost every year.

One-year limited warranty.

Though not the best warranty, Toto’s one-year warranty is nothing compared to the quality of its toilets, and previous users have high praise for Toto toilets as being one of the most durable on the market. But the manufacturer should improve the warranty to increase the confidence of new buyers.

Final Thoughts on Toto Ultramax

Overall, the Toto Ultramax toilet is a good addition to most bathrooms and is very easy to maintain. The powerful G-max flush system, together with the SanaGloss ion barrier, ensures that nothing sticks to the surface of the toilet.

There is no need to flush twice with this fantastic toilet, as the powerful siphon jet will ensure the waste is cleared in just a single flush. The toilet is also quiet in operation and won’t distract people or create unnecessary attention. However, it is quite expensive, and the one-year warranty should be worked on. Besides these, this is a sleek and comfortable toilet to have in the house. I have explained everything you need to know in this Toto Ultramax review.


Question: How do I know whether or not the Toto toilet model I am buying has a SanaGloss finish?
Answer: This is a good question, and many people are not aware of it, only to find out later. To know if the toilet has a SanaGloss finish or now CEFIONET glaze, check its SKU number. For instance, for this model, it should be MS854114SG. If the SKU number doesn’t have SG in the end, then it doesn’t have a SanaGloss finish.

Question: I have a 10-inch rough-in. Will this toilet fit in?
Answer: No, it won’t. Toto makes most toilet models with either a 12-inch or 10-inch rough-in. But for this particular model, it only comes with a 12-inch rough-in. So, if your toilet has a 10-inch rough-in, you will have to consider buying another Toto toilet model not named Toto Ultramax toilet.
