What are your best Tenant-Proofing Rehabs? (Kitchen counters,etc)

[Richard Melino]

I am trying to plan out renovations for a B-class duplex and want to tenant-proof with timeless style. Not trying to go low budget, as want things to last through multiple tenant turns...but also don't want to spend a fortune if avoidable (have cake and eat it too, I guess?)

What are you good and bad experiences with:

Kitchens: countertops, flooring, appliances, etc.

Bathrooms: tile types and materials, shower/bath (plastic insert vs. tub & tile, etc.), toilets, faucets, etc.

General: flooring, window treatments, anything else.

Thanks!
