Questions & Answers


Does toilet come with flush/refill valve and flap or do I need to get my own.

Asked by BigTime73 November 26, 2020

Hi, this is Laura with Kohler Co. I am happy to assist you with your question. All the parts inside the tank are included with the toilet. The supply line and wax ring will be separate purchases. Thank you for choosing Kohler.

Is it quiet?

Asked by Nemo November 22, 2020

It is about the same a a standard toilet.

What is the difference between the Santa Rosa Model 3810-0 and the Santa Rosa K 10491-0

Asked by Goanna November 19, 2020

K-10491-0 and K-3810-0 are both the same toilet; the only difference is that K-3810 is packaged with a Quiet-Close toilet seat. Both models include the Aqua Piston flush valve #1216612.

What is the difference between this product and model number 3810-0?

Asked by Dave November 12, 2020

Hi, this is Laura with Kohler Co. I am happy to assist you with your question. The toilets are identical. The difference lies in the packaging. The Santa Rosa K-3810-0 has recently been revised to include the Brevia Quiet-Close toilet seat. The K-10491-0 Complete Solution box includes the Brevia standard hinge seat, wax ring, and floor hardware. Thank you for choosing Kohler.

the was ring has failed. what size wax ring should i get for a replacement?

Asked by mlminpcb November 2, 2020

The Kohler Santa Rosa Comfort Height is an excellent toilet. I bought four when I remodeled my home. I purchased the EVERBUILT 3"-4" standard wax ring in a six pack. Works great!!

To change the top seat its hard, one screw rotatate with the screw, unable to remove it.

Asked by Tatyka October 10, 2020

Underneath is a wing type nut. Just grab it with your fingers or a pair of pliers and you should be able to remove the screw from the top.

The lid doesn’t even fit :( It’s a $300 toilet and the lid wiggles and doesn’t fit flush. I’m so frustrated. Of course we didn’t notice until after we lugged it down a flight of stairs and installed it. It will be such a hassle to return.

We just had this KOHLER Santa Rosa toilet installed in our guest bathroom 2 days ago. It is a very nice toilet! It’s comfortable and functions very well. The one-piece low profile looks sleek. It is a 5 STAR toilet! HOWEVER, this toilet did not come with the slow-close seat as advertised. The photos describing this toilet show it has a Slow-Close seat. The Product Description says it comes with the Brevia seat. How am I to know that the Brevia seat DOES NOT slow-close as shown in the photo description? The description lead me to believe that the Brevia toilet seat slow’s not confusing at all. Obviously the description is not accurate and lacks clarity. I am very disappointed. This is the 2nd Santa Rosa toilet I’ve purchased. The 1st one, installed a year ago in a different house came with the slow close seat. My daughter also purchased one based on my recommendation. I plan to contact Home Depot Customer service tomorrow. I feel they should provide me with the slow-close seat as currently advertised. And KOHLER needs to change the product description for HD to read...”Comes with the BREVIA seat. Does not Slow-Close” and provide a product link to the Slow-Close seat so it is clear that It must be purchased separately.

Excellent Toilet, the 'comfort height' does make a difference!

Three for Three
Needed to replace three 25-year old builder grade toilets that Mr. Plunger and I became all too familiar with. These new Kohler Santa Rosa toilets are uni-body and a bit heavy. Two toilets went upstairs so I padded the upstairs mid-way landing with cardboard to set the toilets down in order to regain my strength for the final trek to the bathrooms. One toilet flange was below floor level so wax ring SKU 256731 was used. The other two flanges were more or less floor level so wax ring SKU 256462 was used. However, composite shims on two of the toilets were necessary using shim kit SKU 526445. The shims were lightly tapped into place with a hammer and then cut with a retractable utility knife. DAP Alex Fast Dry caulk SKU 753709 was used to caulk the toilet base where it meets the floor tile after the toilets were leveled and the toilet closet bolts tightened down. Fluidmaster SetFast 5/16 in. x 2-1/4 in. No Cut Brass Closet Toilet Bolt Kits SKU 1005074693 were used instead of the supplied toilet closet bolts. However, I still used electrical tape to keep the toilet closet toilet bolts in-place and free from movement once centered 12" from the wall. The caps for the toilet closet bolts move around when using the Fluidmaster kit but so what? The caps are there for aesthetics and don't move unless hit with a mop. It helps to have an extra set of eyes to guide the heavy toilets exactly centered with the toilet closet bolts for final seating. As to toilet operation, all three are flawless performers with real use. When pushing the toilet handle down, there is a momentary lag and then a quiet but brisk single-flush "whoosh". All three toilets are very quiet and refill in a short period of time. No adjustments were required for the fill-line as they were flawless performers out of the box. The "Comfort Height" feature of the Santa Rose toilet is a nice touch toward seated comfort. The stock toilet seats are okay. One of the seat mooring tabs cracked while being made tight to avoid side-to-side movement, but electrical tape adequately holds it together and can't be seen when the cap is engaged. One final note, if you are replacing an older toilet, the tank portion of this toilet may likely have a different, less wide, profile than the toilet you're replacing. It will be helpful to paint the wall behind the toilet if it was already painted around the replacement toilet so as to avoid a visible wall color mismatch.

Love Kohler
Very happy with my purchase. We upgraded all of our toilets to kohler. Great one piece toilet with a good flush, no more double flushing or little flow anymore! Would definitely recommend.

Works great. Uses very little water, but gets everything down with the first flush.

For the money.....
I finally rolled the dice and bought this toilet as a replacement after reading countless reviews. I have to say many people who had some negative things to say were spot on. When I first got the toilet unpacked I honestly was expecting a little more in the packaging given the what I spent. KOHLER provides only the very basics in bolts, with no extras whatsoever. Not even a standard 3/8 water line hose connector, or even a paper instructional booklet to help those who might be mildly challenged trying to do a self install. Not the end of the world, but your left having to read very basic installation instructions on the top of the huge box the toilet shipped in. The same box that eventually gets tossed out for recycling. What happens when something breaks and you need a parts list and item numbers for repairs? Throw in a pretty cheap plastic and non self closing toilet seat, and it really leaves feeling that you paid just for the KOHLER name. There are no added touches to the packaging that I could see which would greatly differentiate this product from that of any competitor. All that aside the toilet runs well so far nsd I've had no issues. The AquaPiston flush technology is very efficient and keeps the noise to a minimum. I've also had no issues with clogging in the week I've owned it with my only real fear being just the thought of what I might have to go through for warranty purposes should something break requiring me to reach out to KOHLER. Some mental KOHLER insurance money would really go a long ways should HD want to call me and say I won 1K for throwing in some pics and writing this review.
