If I purchase the Kohler Portrait tank and Portrait elongated bowl separately online, will I need anything else from Home Depot to install it?

Asked by: Anonymous
Greetings Cheryl, My name is Tom, also known as HD116 both here and at Home Depot's How to Community. I am here today assisting with some product questions and saw yours. In addition to the tank and bowl, you will need a supply line and wax ring kit to complete the installation. Sorry for the delay in response, and thank you for your question.

Customer Reviews

Portrait 1.6 GPF Single Flush Toilet Tank Only in Black Black is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Top quality product delivered quickly My total experience buying this product was great. I quickly found what I wanted, bought it easily and it was shipped quickly. What more could I ask for!

Rated 5 out of 5 by from Just the item I needed I purchased this to replace a cracked tank, and saved a good deal of money over buying a complete commode. The color match was identical, even though the original commode is more than 15 years old. Congratulation to Kohler for maintaining the older product lines! The unit included the valve, and all the necessary hardware it took to install, and was only a 10-minute, one person job.
