I have the glacier bay ceramic towel bar and my grand kids broke one of the holders for the bar. All I need is the ceramic end. Can you tell me where to finb one?

There actually is no Glacier Bay company, this is Home Depots store brand name. You might be able to gets individual parts but for a towel rod I really doubt it. An entire re[lacement is about $20. 24 in. Towel Bar in White Ceramic-BA00007 at The Home Depot (http://www.homedepot.com/Bath-Bath-Hardware-Bath-Accessories-Towel-Bars-Single-Towel-Bars/Glacier-Bay/h_d1/R-202330820/h_d2/ProductDisplay?catalogId=10053&langId=-1&productId=202330820&storeId=10051)

I think it is a Home Depot item. You will need to buy the whole bar or contact manufacturer and they might sell you the part you need.
Good luck.
