Can I deduct full amount paid for these improvements and do I need an appraisal

Converted home to rental. Made all these improvements beforehand. Can I depreciate total amount paid on these on taxes over 27.5 years or do I need an appraisal to assess the value added to depreciate?

 

1. broken shower pan, tore out tile, new shower pan, re-tiled

2. new flooring

3. took down beam for open concept

4. granite counters

 

Thanks,
