This model has all of Kohler’s best features and a little extra.

Flush Ability

The San Raphael is a Water-sense certified toilet that uses 1.28 gallons per flush, saving you thousands of gallons of water annually.

The canister flush valve provides a convenient flushing operation and is powerful enough to get rid of clogs without wasting extra water.

Furthermore, the glazed, skirted trapway increases the efficiency of the flushing system; that means reduced chance of clogs or leaks.

Design

Right off the bat, the one-piece toilet catches your attention.

The seamless integration of the tank and bowl takes away any nooks and crannies where dirt and grime can hide.

The skirted trapway also eliminates spots for bacteria to accumulate, so you don’t have to worry about intense weekly scrubbing; the San Raphael only needs a wipedown every once in a while.

The San Raphael has a seat height of 15” and an elongated bowl to increase user comfort by dispersing body weight.

While the toilet’s height is average, it’s important to note that it’s not ADA compliant so it won’t be accessible to all potential users.

The toilet comes with a Quiet-Close elongated seat to eliminate unintentional slamming.

The Quiet-Close seat also comes with Quick-Release hinges, making cleaning yet again!

The Santa Raphael is only available in the classic white color.

Optional Accessories

If you’re interested in upgrading the San Raphael, there are plenty of compatible Kohler products you can purchase.

The Cachet Nightlight Quiet-Close elongated seat has all the best elements as the traditional Quiet-Close seat with the added bonus of a night light for nighttime bathroom visits.

For heated seats, a 1362736 mounting plate is required. The C³®-23 elongated bidet seat with remote takes your toilet to the next level with adjustable bidet settings.

Pro and Cons

The Best Parts
  • 1.28 gallons per flush
  • Quiet-Close seat included
  • Unique look 
What Needs Work
  • On the expensive side
  • Shipping issues

Summary of Reviews

Users like the toilet’s look and feel, praising its unique build. The Quiet-Close seat is a big hit, as many models usually require you to purchase it separately.

The most common complaint is the toilet’s state upon arrival. Multiple users claim that the first time around they received the toilet in pieces and had to contact Kohler support for another model.
