Is this toilet quiet compared to top quality toilets
Asked by: BL
I am not very familiar with many "top quality" toilets, but this one is relatively quiet, although not silent. The flushing mechanism seems quieter than the older flapper models. It is definitely quieter than the "power flush" models.

A lot of reviews reference the seat being flimsy. Are the seats on each of the two models the same except one has the slow close feature? I'm wondering if I should buy the model with the slow close seat if it will ultimately need to be replaced anyway or just get the other and plan on upgrading the seat. Model # 3810-0 (w/ slow close seat) Model # K-10491-0 (w/out slow close seat)

We installed a quiet close lid which is very good.

Santa Rosa Comfort Height 1-piece 1.28 GPF Single Flush Compact Elongated Toilet with AquaPiston Flush in Black Black is rated 4.5 out of 5 by 1435.

However, for $300 it should have better fit, finish and seat. The Tank Lid does not seat flush with the tank. The Seam is not glazed and is very visibly different. The bottom edge of the toilet that rests on the floor had a bunch of uneven casting shards which would not seat flush to the floor. It caused some rocking of the toilet. So I had to take a file and file the shards smooth. This should not be shipped like this! But it would have been too much of a hassle to return it to the store to order another! And Don't get me started with the AWFUL toilet seat this high end toilet comes with! It is Thin, Flimsy and UNCOMFORTABLE! It also shifts around! And yes, I tightened it! The Aqua Piston is a joke, this thing barely moves any water! It is on the quiet side but I'm not sure it's going to be a great flusher, time will tell.

After 24 years of reliable service the old toilet gave up, and after much research, I decided on this make and model. Installing the new toilet was somewhat of a challenge, since toilet dimensions have changed in 24 years. The first was the toilet shutoff valve was too close the back of the new toilet so that the shut valve handle would not turn without hitting the toilet. I had to remove new toilet and cut out drywall to move the valve slightly over. The other advice I have is this toilet is a one piece design, so it is heavy and awkward to lift and place over the hold down bolts, and making sure you are aligning the wax ring correctly to the floor flange. This was trying in a small space! Now to the toilet itself. Sleek looking one piece design with low flush capacity. One slight touch of the flush handle and the waste is gone in a flash! This toilet design acts like a vacuum when flushed, with no splash back from bowl. I am on a septic tank system and didn't expect this toilet to work as well as it does. I'm amazed how easy it flushes with so little water!

It has powerful flushing with little water. It is a great toilet by design and function, but unfortunately, porcelain coating quality drags down the rating. I bought four toilets. Two are fine and two have imperfect porcelain coating. One has a small grey spot on top of bowl, oh well, I decided to keep it. The other has two long grey hairlines on top of bowl, too obvious to ignore and I decided to exchange. One lid has uneven coating and looks weird. For a toilet with price tag @$300, this is unacceptable. Kohler should 1) improve porcelain coating process, and 2) rinse off dust/debris before reaching their quality control, so the ones with cosmetic deficiency can be caught. I am very happy with Kohler customer service and Home Depot customer service. Both are very responsive. Home Depot customer support scheduled a shipping company to pick up the bad one from my house, and placed a replacement toilet to deliver to my house in two days. Therefore, I still recommend this toilet - do check your new toilet thoroughly right after delivery.

Purchased this model specifically because of the low profile, and this was the only low one we could find under about $500. We've had it just over one month and had to use a plunger twice. Problem is, the shape of opening doesn't work with a standard plunger. Our old toilet, 27 year old, builder installed, never had this kind of problem. Equally disturbing is that it doesn't really clean out with a single flush. So much for saving water. AND, we noticed what looked like blue paint floating around and sticking to the sides of the bowl! We contacted Kohler and they explained that ours was one of the 'random test' models that they spray a blue 'paint like' material into the tank, and it would eventually go away. Sure enough, over a month later and it is going away. We purchased this from Home Depot because it was at least $50 less than other places. Maybe they get all of the test models? I do NOT recommend the Santa Rosa.

Ordered 2 of the Kholer Santa Rosa toilets online with free shipping and pickup at local Home Depot store. Order included online sale price and extra 10% discount with Home Depot coupon that I had received. I was advised when toilets arrived at local store for pickup and traveled to store for product pickup. Upon inspection of product boxes did not have a good feeling due to box damage. Loaded toilets and transported to residence. When boxes opened found both toilet fixture bases broken. Returned fixtures to store and inquired about reorder for replacement toilets at original price paid. I was advised that toilets could only be reordered with my 10% discount as the toilets were no longer on sale. I refused the offer due to the increased cost and requested a credit to my account for the original order purchase price. What started out as a good sale price for the toilets turned into considerable inconvenience considering my time to order products online and travel to retrieve products from store and return to store.

The first Santa Rosa Toilet that I purchased 5 years ago is fantastic.......easy to clean with a simple design. I purchased another Santa Rosa in June, 2019 and after installation noticed that the top lip of the tank was unglazed. Looking at the toilet one would see an unglazed line across the top of the toilet. My existing toilet is perfect with glaze applied over the lip. Kohler advised me that the only remedy was to return the toilet to Home Depot. I returned the toilet and purchased the same model from Home Depot's website. The replacement toilet was not perfect but slightly better than the first. Now for the next problem! When the replacement toilet is flushed, there is a loud gurgling noise at the end of the flush. The original toilet did not do this. Also, my older Santa Rosa did not present with this issue. I decided to pull the toilet and re-seat it with with a new wax ring......still loud gurgling. My guess is that there is an internal casting issue that is causing this sound. Finally, I just gave up due to the exhaustion from having to hump toilets to and from the 2nd floor of my home. I have Kohler products throughout my house and am very disappointed that they would allow this model toilet to pass through their quality control process.

Rated 5 out of 5 by from A nicely designed, functional toilet Bought this to replace an older Kohler normal height 2 piece toilet that developed a leak at the bowl-to-tank gasket that was hard to fix. Anyhow, we needed a "comfort height" toilet for, well, comfort as we get older. The toilet was ordered on the Internet and sent to the local Home Depot. I arranged for pickup and installation through Home Depot, as this is a one-piece toilet and a bit too heavy for my old back. The installer came and put the toilet in, took the old one out and after a week of use, it works great. One would not think the 1.28 GPF would provide a good flush, but it really does -- no problemos. The flush valve is different for a one-piece, and Kohler has a different flush valve system than say American Standard for a one-piece toilet, but I think this will last a long, long time before I need to worry about replacing it. All in all a very good toilet, but it does cost a bit more for the one-piece feature and and a bit more for color, but for us, well worth it.

This is the 4th Santa Rosa we have purchased for our house, it was not level and we didn't notice until it had been installed by our plumber. Definitely a QC issue at Kohler. The the floor was level, water tank was level, it was the porcelain bowl that wasn't. To try to level the bowl plumber would have had to shim about 1/2 inch, and then the back side would have looked crooked. It had to be removed and returned; due to the long lead time we will be purchasing another brand as the contractors are short on time. I would definitely recommend checking that before you install, the first 3 purchased last year, were all fine and function very well.
