What are the pros and cons of installing a bidet?

How expensive/difficult would be to add a bidet to my bathroom (or a toilet with bidet functionality)? Will it add value to my home? Is this a feature that’s increasing in popularity?

Pros:

  • more comfortable to use a bidet instead of toilet spray because it allows the mix of hot/cold water.

Cons:

  • requires a bathroom with extra room for its placement
  • requires an extra drain connection and water supply (cold and hot)
