I am looking for 2 kohler toilets. I like the look of the San Rapheal and I prefer the comfort heiight. I noticed there are different prices

for what looks like the same toilet. Could you explain. Also, I want a quiet flush. What do you recommend.
Asked by: Anonymous
Hello Lisa, The flushing type mechanism, color, lid closure upgrade and seat choice (round & elongated) will effect the cost.

will this toilet fit under a formica counter extention from bathroom vanity?

Asked by: Anonymous
The unit is 21.5" high, and you may want to leave a few inches so you can remove the lid and get inside the tank if needed. If you have further questions, please call a customer care representative at 800-4-KOHLER.

Sometimes needs more than one flush to get toilet paper dropped near front of bowl. Does not always clean waste from sides of bowl. Needs more use of toilet brush than toilets using more water in the flush process. Piston flush is fairly loud.

Just got tires of flapper and ball cock problems so decided to try something completely different. They sure flush well and still haven’t clogged them yet. Pricey but I am thinking they are worth it long term…..

Rated 5 out of 5 by from Elegant low profile I installed this toilet in my shop/office bathroom. I chose 1.0 gal/flush because I am on a septic tank. It's pressurized, so it's a louder flush, but it works well. It's compact and well built.

Rated 4 out of 5 by from Excellent toilet but some drawbacks I purchased two Kohler San Raphael toilet to replace 25 year old toilets that weren't functioning well and to save water. They are pricey plus I had to pay a plumber $150 to install each toilet. This didn't stop me from then replacing the other two in my house (which were still working) so I now have four. The toilet is high quality and looks beautiful in my bathroom and the comfort height is very nice. The Flushmate technology is powerful and literally sucks everything away. It reminds me of an airplane toilet. Two drawbacks though: 1. Noisy flush but not so much that it prevented me from buying the second pair and 2. It doesn't always flush all the paper so OFTEN requires two flushes. That sort of voids the water saving idea. The great features definitely outweighs the two negatives and would recommend this toilet to anyone searching for a quality, high functioning toilet.
