Customer Questions & Answers

The waste pipe rises from the floor 5/8ths inch with a support ring on it that makes it about 1.5 inches larger in diameter. Will this fit over it ?

Asked by: Anonymous
No, but Home Depot sells plastic pieces that attach to via the closet bolts that may help you. Then, build up around the toilet for support and finishing looks & who (but you) will know?

Is the San Raphael a high-efficency toilet?

Asked by: Anonymous
It's supposed to be efficient but the lack of performance requires you to flush more than once for simple jobs.

Thank you for your inquiry. The model toilet you have selected comes with the French Curve toilet seat. The model number for that seat only in Ice Grey is K-4663-95.

Customer Reviews

San Raphael 1-Piece 1.6 GPF Round Front Toilet in Thunder Grey is rated 4.3 out of 5 by 41.
Rated 1 out of 5 by from Terrible design ! Looks nice, but has a fatal flaw. The screws that hold the toilet seat go directly into the toilet base unit. In contrast to most toilets where the bolt or wing nut can be reached from underneath, there is no way to reach this part. The screws get corroded and are difficult to screw out. Worse, in my case, the bolt embedded in the toilet unit apparently came loose. The screw just kept turning uselessly, and there was no way to pry out the screw because the bolt was still attached to the screw even though it had come loose from inside the toilet itself. The toilet had to be disposed !!!

Rated 1 out of 5 by from kohler Rosario one peice tiolet This one piece kohler tiolet is good in theory only. This has been a nightmare, just to change the simpliest things. The tiolet seat and cover does not replace easy. Took 5 days to get the 2 screws out, after almost breaking the tiolet. Screws had to be cheiseled out. Kohler's customer sevice is the worst. After the 1 yr. warranty is over-good luck.Their reps, told us tough, and hung up on us.I will never purchase another one of their products again. Buyer BEWARE!!!!

Rated 5 out of 5 by from Love it! I absolutely love this toilet! It's stylish while being energy efficient. It has a quite refill and flushing system that can be very deceiving, because it leaves you thinking that there's no way it's going to have the flushing power that's required. But, surprisingly and to my amazement, it is more so efficient and powerful than the one I replaced, and it exceeds it's requirement.

Rated 4 out of 5 by from Stylish..(for a toilet) and great performance. I was a bit apprehensive about buying a toilet online, but home depot did a great job! Arrived in perfect condition. Toilet comes with the flexible hose to connect to the waterline, which was a pleasant surprize bc I don't remember it mentioned being included when buying it. The only reason I didn't give it 5 stars is bc sometimes when you are flushing a #2, you have to flush it twice. I adjusted the water level knob, & now it's quite a bit better. Fills quickly and quietly. Love that I'm saving the water and stress on my septic system! Good purchase:)

Rated 1 out of 5 by from Horrible Toilet / poor performance!!! This toilet might be fine with little to no use! It is always clogging and you need to flush twice just for it to flush clean. Changing the toilet seat is impossible and you need to buy a special$50 kit to replace the usually rusted anchors. Do yourself a favor and DO NOT BUY THIS TOILET! Something as simple as changing seat should not require the extra cost of a kit over the price of the $50 seat! I'm extremely disappointed with Kohler and thier lack of help with this matter!

Rated 5 out of 5 by from Good flusher as well as attractive Kohler has two superior flushing systems: Ingenium and Class 5. We bought one of each and both are superior flushers in comparison to what we had before. This model, being a one-piece, is more expensive but certainly more attractive for certain settings.

Rated 5 out of 5 by from Nice compact toilet The Kohler San Raphael was just the ticket for my small Bathroom remolding job. I really like the modern look of the low profile design. The concealed trap way does make it easier to clean. I've had it a week so far and have had no problems with it plunging. Flushing seams as good as my old Toilet that used 3.5 gal. per flush. So the Ingenium flushing system does as advertised.. The Home Depot shipped it to my door step free of charge, plus what I liked about ordering form the Home Depot if there was a problem with it, I could return it to the store in my neck of the woods. No hassle shipping it back.

Rated 5 out of 5 by from This is a Keeper This is a great looking, one piece toliet, perfect in a smaller space. We also have the Rialto, which has some "flushing" issues. Although this one is in a guest bathroom, so far, so good! The Home Depot price is a very good value.
