Customer Questions & Answers

I have a Kohler Portrait Model K-3506-0 toilet and I need to replace the flapper. Which one should I get?

There are two flappers available that look like the one that was in the toilet. The Kohler Flapper for One-Piece toilet looks the most like it, but I can't find a list of which models it will fit. The Kohler flapper with Shark fin looks similar also.

Customer Reviews

Portrait 1-Piece 1.4 GPF Elongated Toilet in Black Black is rated 3.0 out of 5 by 2.
Rated 5 out of 5 by from Great flush power Had a powder room remodel. Professional plumber installed. Easy clean since water flows along all sides of bowl when flushed. Flush is comparable to a power flush. Quiet flush since the tank is small and fills quickly. Uses less water for flushing than my older toilets. Easy flush mechanism for people with disabilities. Have two more toilets to replace and this model will be used again.

Rated 1 out of 5 by from Looks Nice But Doesn't Flush Good At All Have owned this toilet for 10 years. Due to the cost when purchased, I have not replaced it but will sometime this month (enough is enough). Needs at least two to three flushing to send everything down. Constant rodding or plunging. Own two other Kohler toilets and they have no problem.
