George: Thank you for your inquiry with HomeDepot.com. We do not have information as to how many of the Symmons Dia Wall Mounted Toilet Paper Holder in Chrome are in a box. You can order 45 of this item by going on line and "add to car" or by calling HomeDepot.com Customer Service at 800-430-3376. We hope this information is helpful, we appreciate your business.
Dear jewels: Please ignore the reference to 'tank mounted.' I'm not sure why this has been applied to this item, but I have notified our HD rep so it can be removed. This item is designed for wall-mounting and comes with mounting hardware to allow the unit to be attached to either a wood surface, or drywall. Sincerely, Shane Symmons Customer Service
