Santa Rosa toilet
I bought this toilet a month ago and it works fine but the quality of the finish on the tank is below expectations. You can see where it was not glazed and the tank top doesn’t cover it. So far no reply from Koehler how to hide. I love Koehler product but wish I picked a different toilet.

Jenzap, my name is Jessica with Kohler Co. I am sorry to hear that you aren't completely satisfied with the appearance of your Santa Rosa toilets. Due to the unique design of this toilet, there may be a small gap between the tank lid and top of the tank. We do have a tank lid that overhangs the top of the toilet tank. This will hide the gap. Please call our Customer Service team at 1-800-4KOHLER for additional assistance. We're here to help. - Jessica P. Kohler Customer Service.
VERY disappointed with lack of porcelain finish around lid
Just had our new Santa Rosa installed. We are VERY disappointed the porcelain is not finished to the top of the tank. Rough, light brown tank is exposed on the front even with the lid fitting properly. We expected MUCH better from a Kohler product. Otherwise, the toilet appears to work ok.

I like the function of the toilet. I’m not sure if this is how they are all made but in the front at the top of water reservoir the porcelain isn’t covered completely to the top. The lid doesn’t hide it all.

I never gave much thought to toilet style and functionality until I visited Japan. When I remodeled my master bath, I wanted a high quality, minimalistic toilet without spending the money for a Toto. The Kohler Santa Rosa is great. It fits perfectly with my modern Asian design and it takes care of business. When I remodeled my guest bath, I bought a second one. It’s the perfect throne!

Toilet seat will not stay on
Instead of being closed the holes for the mounting of the toilet seat are open and tend to spread open. Cannot keep the seat mounted, I can't imagine why they would have this configuration. The only solution I see is to buy a new toilet seat. I would not recommend anyone to buy this unit with this configuration.

Hello Len, this is Laura with Kohler Co. I am sorry your seat is not staying mounted on the bowl. The hinge caps must be closed to prevent the seat from moving. If the hinge caps are not working properly, the seat may come loose. Please call 1-800-4Kohler so we may assist you with the hinge on your toilet seat. We want to help! Sincerely, M. Laura K., Kohler Customer Service
Hard to repair
From the beginning the seal in the tank has leaked. Periodic “whoosh” noise as water escapes into bowl. Paid plumber several times to replace the seal, but it doesn’t last long. Now there is a high-pitched squeal at end of flush cycle as water finishes filling the tank, probably coming from the float mechanism. I agree - don’t buy unless you are a plumber - not easy to repair.

Katie, my name is Jessica with Kohler Customer Service. I am sorry to hear of the issues you are experiencing with your Santa Rosa toilet. This is nothing you should expect when you choose Kohler. The squeal you are hearing when the water is filling the tank can be due to there being debris in the fill valve, the following link is to an instructional video showing how to flush the valve out: https://bit.ly/39x9Tgo. If the issue continues after the valve has been flushed out, please contact our Customer Service team at 1-800-4Kohler. We look forward to hearing from you soon! - Jessica P. Kohler Customer Service.
leaking from the factory
Highly recommend not buying this product! Bought 2 brands and this overpriced product leaked from the reservoir immediately!!! The other brand purchased was the Glacier Bay for $160, no issues.

Hello, this is Sarah with Kohler Co. I'm very sorry to hear your Santa Rosa toilet is leaking upon installation. This is nothing you should expect during normal use on a new toilet. This may be caused by a seal not holding within the tank. To narrow down the location of the leak, we would suggest performing a water test. Please follow this link for an explanation on how to perform this test: https://bit.ly/2O4cg0R. Please email our Customer Service team directly at KohlerCustServ@kohler.com with the results. We look forward to helping you soon!. -Sarah S. Kohler Customer Service

My experience with this has been very pleasant. The installation was easy and not difficult, the prep work for the install was somewhat involved but that was the existing conditions not the unit. The operation and function of the unit has been excellent so far, time will tell regarding the internals build durability and performance. See how the Aquapiston holds up. Very comfortable in use and is efficient. An area for improvement would be get a more complete glazing on the top surface rim of the tank. Very pleased with them, purchased 3 and installed them, all good to date. Have had them for several months now, no issues as of yet. I am content and happy with these units, would not hesitate to recommend them.

I bought 3 of these to replace 20+ year old low flow tech toilets that could not flush childrens #2s. The Kohler Santa Rose toilets were easy to install once i got the process figured out. I'm not a plumber but fairly handy around the house, made a couple trips to the hardware store for a flange repair kit (one cracked), extra wax rings (resetting the toilet due to cracked flange) and longer supply lines (toilets were taller than my old ones). These toilets look great, the one piece feature seams like it will be easier to clean, the flush is low flow but seams powerful. If you hold the handle down it seems to flush harder versus quick flush We have only had them for two days and we are pleased so far.

I'm disappointed
Too bad Home Depot's toilet display is up so high a person can't get a good look at the products or I likely wouldn't have bought this about 5 months ago. I don't it. The tank lid only stays put on the left side, so every time someone sits, the right side pushes back against the wall. The tank rim isn't glazed, bacteria to get in there & you can see already mold is growing. There is a warning sticker about cleaning the tank, and voiding the warranty, so I'm not sure what is okay to use. Inside the bowl at the front is a "spout" that makes cleaning impossible. The toilet is uncomfortably high and narrow for a 5'7" 128 lb person. It does flush okay or I'd give it 1 star.
