Question: is the flushing button made of metal or plastic?
Document: we wanted an attractive commode for a small cottage bathroom and this fits perfectly, looks great AND helps conserve water with the built-in dual flush technology.
We just remodled our bathroom and were very pleased at the sleak design of this toilet! It also was designed not to have the indentions on the sides, which catch everything in a bathroom! We were very happy with it!
My wife and I had a new home built two years ago and had the Kohler Persuade Comfort Height Dual Flush Toilet installed in the master bathroom. It is without a doubt the worst toilet we have ever owned. It flushes solids fine but does not flush toilet paper properly. It usually takes two flushes, sometimes three to get the toilet paper to go.
I know its strange to have accolades for a toilet, but this is a wonderfully constructed toilet. It is a bit different on how you put it together and the only thing we had to do different is had to get a hammer drill to put the bolts to the floor, I have a cement slab. But renting the drill was easy and it worked out very nicely. It flushes great and it refills very fast.
Answer: no
