Thank you for your question. The tumblers are not sold separately.
Hi, Sue Sue. You can view the size specifications by clicking on the More Info tab, then the link to the Specifications PDF, or you can view it here: http://www.homedepot.com/catalog/pdfImages/68/68ac9d5e-be98-4caf-94b8-2177da0d81e1.pdf. Thanks for reaching out.
Thank you for your question. They do not supply us with the size of the tumbler but one is included with the purchase of the holder.
