Questions & Answers

Is this product available with stainless or brushed nickel trip level handle?

Asked by: Sas
I had the same issue and purchased a brushed nickel trip lever kit, part number is K1025329-BN. All you have to do is unscrew the piece that came with the toilet and attach it to the new handle after removing the inside parts that came with the new handle. Super easy, it took 5 minutes. I paid $28 for the kit.

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: Lisa
Hello Lisa, The flushing type mechanism, color, lid closure upgrade and seat choice (round & elongated) will effect the cost.

San Raphael Comfort Height 1-piece 1 GPF Single Flush Elongated Toilet in Black is rated 3.9 out of 5 by 45.

Noisy 4, Trip arm only loosely attached to trip clever and sometimes falls off when you flush it. 5. Doesn't always flush all the paper: despite what you see in the Sloan/Flushmate videos. 6,Kohler staff should be versed in all aspects of the toilet function. As it is now, Kohler only deals with problems related to the china. They refer you to Sloan for all other issues. Since it is relatively new technology you will probably have questions about function.

We originally purchased this toilet from Home Depot online using the ship to store option. When we unpacked it at home, the base was broken. Home Depot processed the return and refund without question but the hassle and delay of locating another toilet after waiting 10 days was not appreciated. We wound up purchasing a replacement toilet from a local plumbing supply distributor because we could not wait any longer to install. My suggestion when picking up a toilet from Home Depot, open the box and inspect it before leaving the store, it will potentially save you a lot of time and hassle. The toilet is a little loud but the extra oomph on the flush is well worth it.

Ever since the late 1990's, when the government started to tell toilet manufacturers how to make more "efficient" toilets, the stools that we have purchased have largely proved to be ineffective if not useless. We have multiple bathrooms and every 3-4 years, we charge out a stool to see if they have gotten any better. Well, for those of you like us - who have been waiting for the functional stool - it has finally arrived. This stool is terrific. For anyone who has tested toilets, you have heard of the five big mac capacity and this stool is that - and more. It has commercial toilet pressure and aside from the 3 second jet engine roar of the pressure mechanism, this stool is effective, quiet and quick to refill. This is one terrific apparatus.

Since I ordered it online, I did not have the opportunity to see it before it was installed and started using it. I thought of returning it, but it would be too costly to have the plumber remove and install a different one. I paid $700 for it, and thought it would be perfect, being a Koehler. I've had it less than a month. Please feel free to pass my review on to the company. Thank you.

After about 3.5 hours of conversations with the flush company and Kohler, Kohler gave me the name of a warranty repair service about 1:30 hrs away. They will be at my house in Cleveland on Nov. 17, 2017 to see if they can fix it.

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.

I don’t know how the toilet worked, but it was broken when it arrived and I was told I had to reorder on line. when I went to do that it was no longer available on line and we had already peeped the bathroom for it. so, there were major e delays and additional expense because of it.
