Powerful Gravity Fed Flush Mechanism
The toilet features a gravity-fed flushing system, one of the most powerful and effective in performance. In addition, it has the AquaPiston flushing canister that allows water to flow into the bowl from all sides. It increases the power and effectiveness of the flush. The big flush valve (3 inches) and large concealed Trapway (2.125 inches) play a vital role in the effective clearance of waste in the bowl.
Easy to clean and maintain
Since it is a one-piece toilet with an integrated tank and bowl, cleaning will be easy and fast. Furthermore, this toilet is easy to maintain as the bowl and tank are one piece. Thus there is no place for debris, mold, or dirt to hide.
Comfort Height Toilet
The toilet is of a standard height which makes it ideal for use by different people. However, the round front bowl is not as comfortable as the elongated bowl design.
Meets WaterSense Standards
Kohler San Souci meets the EPA standards, using less than 1.28 GPF. This implies that the toilet will help you save water and have a lower water bill. You will be able to save more than 16,500 gallons of water per year.

Installing this one-piece toilet isn’t very difficult. All you need is a helper, and you will fix it within no time.

Hence you will have to purchase it separately.
One-year limited warranty
The manufacturer offers a one-year limited warranty and a 90-day money-back guarantee. This is great, but the warranty should be improved on.

Solve common Kohler San Souci toilet problems
There are lots of internal issues that the Kohler San Souci toilet faces. If you do not take proper measures, the entire toilet system may collapse. Here I am enlisting some of the severe problems of the san Souci toilet,
The Fill Valve Collapsed
The fill valve, which is the main part that allows water to enter the tank, may collapse. If the water has excessive iron or minerals, it may block the toilet parts. The fill valve may have faced the same problem. It allows the water to keep flowing into the tank, which causes over-flooding.
Solutions: You need to clean and replace the seal if it is damaged or collects rust in it. Replace the flush valve seal and the fill valve with new ones. Replace the damaged piston or seat washer, and fill the valve seat if necessary. Tight the flush valve gasket nut if it is leaking.
Poor flushing performance
Poor flushing may be initiated due to a worn-out flush button or if the water level is not at the correct level. A blockage in the main water supply line can also yield no flushing.
Solutions: Repair the chain to the trip lever or flush valve and adjust the correct water level for strong flushing. The trapway, jet, and rim holes must be cleared.
Lack of efficiency of the Toilet Tank
The tank can exert some unwanted issues, just as not filing itself in the quick possible time.
Easy Fix: Clean and clear the supply line and the valve inlet and open the water supply shut-off valve.
Excessive noise problem
The toilet might produce some unnatural ghostly gurgling sound while filling the tank or during flushing. This is because the valve head might have been dirty or the water pressure is too high. Sometimes a jam in the bolts and connection also produces this horrible sound effect.
Solutions: You should close the water supply shut-off valve, clean the valve head, and flush the lines.
Comparison: Kohler San Souci Vs. Santa Rosa
The Kohler Santa rosa is a tremendous one-piece toilet that comes with a powerful flushing system. It is a comfort height toilet that spectacularly consumes minimum water in every flush, accurately 1.28 gpf. Its excellent ergonomic design can please anyone. The toilet seat is elongated in shape, ensuring maximum comfort and ease, and the fantastic WaterSense technology can save much of your bill. And the best part of this toilet is that it is a budget-friendly product that will not put much pressure on your pocket.
The san Souci is another colossal edition by the renowned brand Kohler. The main difference between San Souci and Santa Rosa is that Santa Rosa has an epic MAP score of around 1000. The MAP value of the san Souci is less than 800, which means Santa rosa can evacuate a much larger amount of waste in each flush. San Souci uses a weak AquaPiston flush valve, which makes the flush far more clumsy than the Santa rosa. So, according to this informative comparison, Santa Rosa seems more powerful and effective than Kohler San Souci.
The Kohler San Souci is a great toilet for smaller bathrooms due to its compact design. It has a very effective flushing mechanism and clears waste in just a single flush. Also, there are no leaks, and it uses only 1.28 gallons of water per flush. With its lovely design and outstanding features, this is a nice toilet to invest in.
Question: Can I install this toilet in the restroom?
Answer: No, you can’t. This is because the toilet is not ADA-compliant. It is a requirement that only ADA-compliant toilets should be installed in restrooms or public areas. But the Kohler San Souci is a wonderful toilet for homeowners or offices.
Question: Can I install the toilet by myself?
Answer: Though this is possible, it is not recommended at all. This is because the San Souci one-piece toilet is quite heavy, as the tank and bowl are adjoined together. Installing this toilet yourself is risky as you may drop or damage it while installing it. You should get a helper to assist you in proper and safe installation.
