It is a Toto, a brand I love  have brought me great pleasure. Cleans easily but don’t use any strong cleaners on it. A bit pricey, the skirt makes a tight area to fasten it. But skirt gives it a clean look and makes cleaning much easier. Having huge trouble putting a Toto bidet on it, tried three times. Still no success. The water surface is a bit small. Not sure if the big flush will do it. Looks nice, not quite high enough for me.
