Beauty and Toilet Humor Too

 from mt vernon., NY– Verified Buyer

The elegant shape alone is worth the price. Added feature on top. Within one small chrome circle, two semi-circle push buttons. Button number one for less water and button number two for more water. Use your imagination.

very satisfied

 from Jackson, WY– Verified Buyer

first, the toilet is beautiful and works very well in small & large flushing. it gets the job done. No problems with operation or installation. however, your listing this item as aquia LI is incorrect as aquia I has been discontinued and replaced by aquia II. aquia I has an open back design with a pvc trap that sticks out the back of the base of the toilet. The aquia II which is the model you sold me, is a much better design, no funky pvc trap piece and closed base design make this unit much more desirable. wayfair had the best price on this unit, but the better part of the savings went away after charging $140.00 for shipping on an item that was advertised as with free shipping. this would not be so bad if delivery was timely, but this was not the case. at least it arrived unbroken, so i guess i should'nt complain too much.
