Summary : Looking options which are not labor intensive for bathroom remodel , which is already in great condition.  The option doesn't have to be cheap , but should be less labor intensive

Longer version :

Bathroom : Great condition , well built , but outdated , needs cosmetic update to make it look modern

Problem statement : Feel bad to rip off everything , found some options online , but I feel the demo videos from these companies don't tell the whole story , so was looking for things that BP members practically used and have feedback on.

Ideas researched so far :

• Luxury tile like wall panels - so you can install the panel in one go rather than tiling
• Tile over Tile - of course with some important considerations such as condition of existing tile
• Reglazing bath tub
• Painting existing tiles and grouting 
• Updating all the fixtures , cabinets with high end items
