Great toilet, easy to use. This is the second one I have installed in my house. I love the two button system for flushing.
This is a standard size toilet.
They are standard so where did you measure from and when was your house built? They should work anyway being 1 piece they will not break like a two-piece might.
No. I purchased one.
If you're referring to slow-close seat cover, I'm sure if HD doesn't carry, any plumbing supply should. You could also check online. Good Luck
Brent: Fluidmaster makes the replacement valve. I think under $18. Check it out on you tube. Looks like a 10 minute job. Less on the second one. Homer probably has one on the shelf just for you.
Not sure what you mean by "intention," but the toilet fits any standard toilet flange--flat or tapered. The toilet comes with a wax ring and mounting bolts.
It is the exact height of my kitchen chairs, approximately 18” tall.
This is the chair height or comfort height bowl which is 16.5 inches to the bowl. Seat adds height. I’m unaware of any standard manufactured toilets with a taller bowl height.
