Thank you for your question regarding the warranty for the Delta Single-Setting Raincan Shower Head.
I am very sorry to hear that the rubber nubbins are wearing away and I am happy to assist you today.
This model has a limited-lifetime warranty, so as long as you are the original owner of the shower head, the product will come with a limited-lifetime warranty for as long as you own the model.
At your earliest convenience, if you could please respond back to the email I sent to you or you may give us a call at 800-345-3358 and we will be happy to help you.
We hope to hear back from you soon!
