Depreciation schedule for Kitchen Appliances/Cabinets and Bathroom Fixtures Renovation

I renovated a kitchen and two bathrooms and then put a rental property into service.  I've read appliances can be depreciated over a 5-year schedule and kitchen cabinets over 7-years.

 

How are kitchen countertops depreciated?  How about bathroom fixtures?  

 

Are there any downsides to using a faster depreciation schedule on the aforementioned items?
