  • Comfort Height: Comfort Height toilets offer the greatest accessibility and ease of use with a bowl height of between 16-1/2" and 18", the same as a standard chair.
  • WaterSense Certified: To help make a difference on a global scale and to further its role as an industry leader in eco-performance practices, Kohler has established partnerships with a number of environmental organizations, including WaterSense.

Rated 5 out of 5 by from Throw away the plunger Purchased and installed three white Santa Rosa's in our new construction. Was a bit concerned as we had no experience with 1.28 gal flush models, but I have to say, Kohler has definitely figured it out. They've now been in service for 8 months and not one clog! Better than the AS Champions we had in our previous home. Comments about them being noisy? It sounds like a toilet flushing... you were expecting something different?. A great value without breaking the budget.

Rated 5 out of 5 by from Great Toilet, great service I got this toilet in the "Mexican Sand" color which was as portrayed on the website. It was less $$ than the local dealer (of course!) plus it was in stock where the local dealer was going to take 4-6 weeks. It It came exactly on the day they said it would - the morning of Hurricane Sandy which didn't hit our area until later that day! No problems with the delivery, the box was intact with no damage and the toilet was in perfect condition. It was installed a few days later and I just LOVE the operation. Love too that it uses only 1.28 gals instead of the 1.6 gals that I had had there. All in all, a great experience with Facetdirect. Would order from them again and again (and have)...

Rated 5 out of 5 by from EXCELLENT CUSTOMER SERVICE Well, we opened the box yesterday, only to find that there was a HUGE broken piece on the toilet base. I called and expected to receive the usual run-around ('You accepted it, so you deal with it.' Sorry, it's been more than 2 weeks....'). To make a long story short, I got a 'Sorry, we'll ship you another on in 1-2 days.' Smart, very smart. THIS is the way to keep happy customers and get great word of mouth advertising. THANK YOU, FAUCETDIRECT !!

Rated 5 out of 5 by from best valued one piece toilet This is the best looking, best performing, best priced one piece toilet on the market in my opinion. I use it in almost all my bathroom remodels and new builds.

Rated 5 out of 5 by from High quality product I have used Kohler products before so as expected I was very satisfied with my purchase. Only issue I had was that it was a chore to get the seat to line up properly with the bowl. Kohler have changed the attachment fittings to allow for simple seat removal for cleaning but the result is too much play in the fittings but not enough adjustment. The purchase was simple and delivery very quick.

Rated 5 out of 5 by from Kohler Santa Rosa Looks great, flushes well, easy to install. Installed about a month ago, very happy with the performance: flushes completely and cleans sides well. We've had to flush a second time once or twice, but I think that's to be expected with any 1.28 gallon toilet.

Rated 5 out of 5 by from Great purchase; Great service We ordered 2 Santa Rosa Kohler toilets, which were much less expensive than ordering from Kohler direct for the same exact product. The sales rep. worked with us to help with shipping costs (coupon) since because of the weight we had to pay freight. We received both toilets in one shipment within 3 days. They are now installed and look great, with terrific functionality! Thank you Faucet Direct.com!

Rated 5 out of 5 by from Toilet Purchase Wanted a black toilet for our bathroom we were remodeling and didn't want to spend 600-800 as we have seen them priced. Found a Kohler on your site and not only did we get a great price...it arrived quickly and it looks great in our bathroom. We have ordered many things and this was another great product! Thank you!
