Product Reviews

Santa Rosa Comfort Height One-Piece Compact Elongated 1.28 GPF Toilet 5 5 1 1
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. May 21, 2011

Why don't we show the price?

Like many retailers, FaucetDirect.com can choose to set its own prices independently. And even though manufacturers require FaucetDirect.com and other retailers to display a product's "minimum advertised price" (or MAP), the retailer can choose to sell for less than that. But the price must be conveyed in other ways, and each individual manufacturer's MAP policy determines where the price can be seen.

To see the price for this product at FaucetDirect.com, you'll need to place it in your shopping cart, and maybe even proceed to final checkout. If you're not ready to buy the product, simply remove it from the cart.

FaucetDirect.com apologizes for any inconvenience. We'd just like to offer you the chance to save extra money while we adhere to manufacturers' MAP policies. FaucetDirect.com is also working to educate manufacturers on how their policies impact customers and their buying behavior.
