A little pricey but it functions well and looks FANTASTIC. The AquaPiston Flush Technology seems to work better than older technology of the past. Will I be saying this a year from now? Time will tell. For now, I would recommend buying this product.

Huge upgrade for the money
Very high quality, fit and finish in this lower priced toilet. It has a timeless but brand new look and it transformed our bathroom. We were looking for an "old timey" toilet with modern internals and this is it. Great looks, powerful flush, uses less water than our old one too. Now to replace the sink!

Very Pleased
Very pleased, we purchased to match the pedestal sink. The toilet stands a little taller than our standard unit and is more comfortable to use in a sitting position. It has a duel flush system; one for liquids and one for solids which is very efficient and save water. The tank refills quickly and surprisingly is very quite. The unit is very solid and is stylish for our power room. We are very pleased with this purchase

Great product! Super happy!
This toilet is perfect for our tiny little bathroom! It's the only toilet I could find with a round bowl (not elongated) at comfort height, and it's perfect! We are actually getting another one for our second bathroom! It has a nice look, classic style. Very Nice!!!

Nice toilet
I wanted a round toilet in my mudroom since I needed easy access to an open closet I am building that sits next to this toilet. I save about 3" in length with the round opposed to an elongated and I think it will make a difference. The toilet is attractive and flushes well. One quick flush for liquids and small solids. Hold down the handle a second or two longer for bigger solids....sorry if this grosses anyone out. The reason I gave 4 stars for quality is that the front of my base comes to a small point where the two sides of the porcelain bowl were fused together. Almost looks like second quality. I didn't have time to reorder so I installed the toilet anyway. Still disappointed that the base has a small "nose" in the front. Easy install and very pretty toilet. I have the elongated Memoirs with the "stately" tank lid in my powder room.
