My rough in seems to be 11 !/2 inches not 12 " - will this still work?

Asked by Cheryl November 29, 2020
1
Answer

Yes. With a 12 inch rough in there is just over an inch between the tank and the wall. You'll end up with about 3/4 to 1 inch of space.

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.

Response from Kohler Product ExpertAugust 9, 2020
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 ordered this toilet for my master bedroom renovation with the expectation of a larger than normal (by today's standards) water surface area and excellent Kohler performance. After completing the renovation and testing it out, I was not disappointed. I really hate the tiny water surface area of most of today's water sense toilets. The water surface area of this toilet is about 11.5" long by 9" wide and sits higher than most. Don't ask me to explain if you don't know why this is important. The flushing action is also great. Compared to my other toilet (Delta), the effort to push the flush handle is so gentle. And now that I have the soft close on this toilet seat, I have to stop myself from accidentally slamming the seat when visiting other people's houses. Know that if you're installing this yourself, it's very heavy when compared to the two-piece toilets that you can install one piece at a time. The one thing that disappoints on this toilet is the porcelain finish. Rather than seeing all white porcelain, Kohler did not glaze the edge at the top of the tank and even with the tank lid on, you can see a darker, un-glazed rim along the top at the front. I expected better for a Kohler product, but still a great toilet.

Toilets IN STOCK at my local Home Depot with tanks that fit under my 29" bathroom counter were limited to two; this top-of-the-line Kohler and a less expensive Glacier Bay.  I hadn't planned on spending $300 on a commode but now I'm glad I did. Here's why: This is a one piece toilet. It will never, ever leak between tank and bowl/pedestal. It's got Kohler's latest jet flush technology ("Aquapiston") that works exceedingly well. The "stuff" goes away. Every time. Using a minimum of water.  The height of the water in the Kohler's bowl is correct (and adjustable) so "product" lands in water, not on dry porcelain, meaning you don't have to clean this toilet after every use like SOME low-flush commodes. Those are the worst designed toilets ever.  They're simply not sanitary!   They often stink, nullifying the whole purpose of having water in the bowl to begin with!  The toilet bowl and seat on the Santa Rosa are  LARGER than average, despite the tank being a few inches shorter. It's a potty suitable for BIG people. But that also means for us men, a bigger target to aim at and fewer drops on/over the rim.  It's not excessively large or anything, you're not going to fall in.  Downsides?  A) Price, and B) This commode doesn't use the traditional float and flush valve hardware available in ANY hardware store for the past 75 years.   NONE of the new "jet-flush," "power piston,..." hi-tech toilets are constructed using "generic" parts anymore.  Traditional parts simply can't make a 1.28 gallon toilet flush successfully., EVERY SINGLE TIME.  But the added cost and complexity, spread out over ten years, is peanuts compared to the aggravation of a low-flow that performs poorly. This potty doesn't have high/low flush capability.  Why?  It doesn't need it!  At a mere 1.28 gallons per flush it still gets rid of the big poops with multiple papers.  Every. Single. Time.  Dreading having to install a low-water toilet? Hate the one you currently have? Here's one that actually WORKS!   It will, however, co$t you!   Summary: A top of the line toilet that makes the nasty stuff go away using the least amount of water. Never requires a second flush. Suitable for large people but fine for the rest of us too. Easier to get on and off of because it's a bit taller than most despite having a SHORTER tank height. One piece design. Justifies it's premium price because it DOES exactly what you want a toilet to do.

I've had mine installed about five weeks. Paid about $300 for it. Had to special order it because the one in the store (looked identical) did not come with a seat - and the one you special ordered, came with the slow-close seat. it was worth the $20 or $30 savings to wait a few days. Obviously, these one-piece units are harder to install because you need to lift the both the bowl and the tank at the same time. My tip: there is an opening between the bowl and the water path. I used a 2-inch wide tie-down strap to make a loop and then I was able to use my shoulders to lift and use my hands to fine-tune the position of the toilet. I also needed my wife to help align the bolt holes in the base. The bathroom floor is not perfect, so I had to use wooden shims to level, but this was very easy to do and I trimmed them so they can't be seen and the toilet feels rock-solid. It looks beautiful. My two complaints are 1) If you want a complete flush, you have to hold the flush handle down until the water from the reservoir has completely emptied. If you just flick the handle you will not get a good flush. Some people might like this, but this is the guest bathroom and it's kind of embarrassing to give them a tutorial on how to use the toilet! 2) there a slight leak somewhere and the toilet runs for about six seconds every 90 minutes. Not a major problem, but a brand-new $300 toilet should not have this problem.

I would recommend this toilet. But know that it is a high seat level which is great for me as I am 6‘3“ tall but the rest of my family feels it’s a bit too high. It flushes very efficiently. We love the fact it’s a one piece and few were nooks and crannies to clean on the toilet.

Finally after 28 years I needed to upgrade the toilet in my master bath. Did a lot of research on the web and finally decided to go with Kohler’s Santa Rosa model. It always seemed to appear in everyone’s top Kohler toilet list. It was easy enough to install and it looks sleek and stylish. Will have to get used to the quick refill times, it’s ready to flush in seconds unlike the old 5 gallon toilet I’ve had for years. This thing uses a minimum of water and seems to flush everything ok. Love the included “slow close” seat and lid! It does not contain a wax ring! Hopefully it’ll last like the old ones!
