Features of Kohler Santa Rosa Toilet

This model has very appealing and immense features. Let’s have a detailed look at each of the Santa Rosa toilet specs.

Low Water Consumption

The Kohler Santa Rosa comfort height toilet consumes only 1.28 GPF. However, this doesn’t mean it is weaker in flushing; it uses the AquaPiston technology that allows for an all-rounded 360 degrees flush while saving water. Also, the canister design provides leak protection as the seal material is 90% less exposed than the 3-inch flapper.

It is WaterSense Certified which means your water bills will be eligible for rebates.

Powerful Flushing System

Easy Installation

It is quite easy to install the Kohler Santa Rosa since it comes with provisions for mounting holes. These holes are beneficial when it comes to installing toilets on varying types of bathroom floors as well as making it stable.

Frequently Asked Questions

Q1: Is the Kohler Santa Rosa Toilet a good Choice?

Yes, it is. Though quite affordable, the Kohler Santa Rosa is a one-piece toilet that comes with the revolutionary AquaPiston technology, in addition to its compact design. The Kohler brand is well-known for its production of high-efficiency toilets and the Santa Rosa is no exception. It boasts of features that will have you save on your water bill as it highly conserves water using only 1.28 gallons per flush.

Q2: What are the Steps for Installing the Kohler Santa Rosa Toilet?

KOHLER Santa Rosa Toilet
    1. Ensure that the flange is ready – the hole should be open. You don’t need to worry if you already had an old toilet in the same position you intend to install the new toilet.
    2. Place the bolts on the flange. The holes are already created for the bolts to just slide in. Once you complete this process, slide down the wax ring which acts as a gasket between the toilet’s base and the flange.
    3. Assess the installation environment to ensure that the line supplying the water is not in a tight corner. If this is the case, this would be the appropriate stage to have it fixed to avoid problems in the future.
    4. Now, place the Kohler Santa Rosa toilet in. The best way would be to lift it from the seat and have it between your legs. Due to its asymmetrical shape, lifting it from another angle might cause it to fall and break. The toilet should perfectly fit into the bolts you had placed previously.
    5. Once the toilet is correctly in place and it’s not rocking, you can now put the bolt washer in. Look out for the instruction that reads “This Way Up”. Then add a nut. When using a plier to tighten the toilet, don’t make it excessively tight because it will be susceptible to cracking. We would recommend that you tighten the bolts manually instead of using a socket wrench so that you lessen the chances of breaking the bowl. If you are skilled and would know when to halt the tightening, then you can use the socket wrench.
    6. Connect the line that supplies water to the tank using your bare hands instead of tools. The reason is to avoid breaking the material or shifting the fill valve since the pipe and fittings are made of plastic.
    7. Once you have fixed the supply line, it’s necessary to try out if the toilet is actually working. Allow the water to fill the bowl and tank, put some toilet paper into the bowl then flush it severally to check if it works well without leakages and all. In case there’s a problem, you may have to get a plumber to check it out.
    8. Next, place the tank lid on, followed by the toilet seat, not forgetting to cover the bolts with the dust cap.
    9. Finally, another flush won’t hurt just to check if everything is working as it should.

Q3: How can I effectively clean the Kohler Santa Rosa Toilet?

Kohler Santa Rosa Review

Before cleaning you’ll need: toilet cleaner, paper towels, eye protection wear, face mask, rubber gloves, sprayer cleaner, and a brush.

    1. First and foremost, remove any items on top of the tank cover and around the toilet to avoid splashing toilet water or toilet cleaner on them as well as preventing items from falling into the toilet bowl.
    2. Next, flush the toilet then pour cleaning detergent close to the rim of the toilet bowl to avoid dilution. Also, ensure that the lid of the seat is down to prevent splashing or spraying.
    3. As the solution is soaking in the bowl, you can use that time to clean the toilet’s exterior starting with the tank lid, the tank exterior, and the handle.
    4. Shift your attention to the toilet seat. Scrub it thoroughly then use a wet cloth to wipe the hinges and the seat.
    5. Now you can scrub the toilet bowl with the brush from the top moving downwards, also under the rim. Don’t hesitate to push the brush further into the drain hole as you scrub to remove stains.
    6. Once this is complete, wipe the Kohler Santa Rosa toilet parts with a paper towel then flush it for a clean rinse. Once in a while, you may need to get a plumber to help you clean the tank to prevent it from rusting.

A few Precautions to note when Cleaning:

  • Consider the necessary safety measures you’ll need to take, especially using protective equipment since some of the solutions you may be using could irritate your body.
  • Avoid using sponges. They are a perfect breeding ground for bacteria. If you don’t have an alternative, then ensure that they are first sterilized.
  • Ensure that the detergents you are using are porcelain-friendly. The Kohler Santa Rosa toilet body is made of porcelain. So, avoid any products with chemicals that could damage it. You’d rather opt for popular cleaning brands if you aren’t sure.

Final Thoughts

We definitely recommend the Santa Rosa toilet from Kohler for a number of reasons; it is WaterSense certified as it meets the EPA standards; it features the AquaPiston flushing technology while it uses 1.28 gallons per flush yet eliminates all the waste subsequently conserving water.

It also comes in a variety of colors and you get to select one that goes along with the fixtures and fittings in your bathroom.

Another feature is the comfort height which means the toilet seat is two inches higher than popular models making it suitable for use by even people with disabilities. While there are other equally good Kohler toilets like the San Souci, Santa Rosa is a great option if you are on a budget.

This Kohler Santa Rosa toilet review has covered in great detail what you need to know while you make a decision on which toilet model to settle on.
