The TOTO Neorest NX1 and TOTO Neorest 550H are high performing units packed with cutting edge features designed to maximize comfort, convenience and cleanliness. Functionally, they’re very similar, though  the NX1 does feature a redesigned bowl, flushing system and seat that are even more high performing than on past models. They also look quite different and are constructed from different materials.

Looks & Construction

The TOTO Neorest NX1 is crafted from high quality vitreous china and has ultra-modern, rounded curves that will automatically elevate the look of any bathroom. While the TOTO Neorest 550H is a stylish unit with streamlined, angled contours, it can’t quite match the NX1’s exceptionally clean, sleek design. The Neorest 550H also includes more plastic components than the NX1, which some feel represent a decrease in quality.

Though few units on the market today can measure up to the Neorest NX1’s gorgeous silhouette, one potential downside is that it is only available in white, so it may not be the best fit for users who need a beige unit. On the other hand, the TOTO Neorest 550H comes in both white and beige, making it a versatile choice for a variety of bathroom color schemes.

NX1 Upgrades

The TOTO Neorest NX1 comes with a few upgrades to the bowl, seat and flushing system that set it head and shoulders above its competition. First, TOTO has reconfigured its signature Tornado Flush system to make it more powerful than ever before, enabling the flush to sweep waste away from areas of the bowl where its likely to stick. In addition, the new rimless design of the bowl gives dirt, germs and residue no place to hide and makes cleaning the bowl easier and more convenient than ever before. Finally, the updated seat design provides a generous, sturdy base for increased comfort and support, and the universal seat height makes it easily accessible for users with physical mobility limitations.


Final Thoughts

When all is said and done, both units offer exceptional performance and are an instant upgrade for any bathroom. However, the TOTO Neorest NX1 is crafted out of solid porcelain, features an unbeatably sleek design, and offers several upgrades to the bowl, seat and flush system that the Neorest 550H doesn’t have. If, however, you’re in need of a beige unit, the Neorest 550H is a great option to consider as it comes in that color and still offers many of the top tier amenities included with the Neorest NX1, all for a lower price.
