I also feel 17 is too wide even 19mm is extremely wide,,, although I shoot bathrooms as well,,, But that is where 14mm comes in handy.
The buildings of today are stacked so closely so 19mm will do the job nicely since 24mm often is too little coverage.
Today I often have to stitch to get the shot, if there is not enough space to move back or if there are unwanted obstacles in the way when moving back.
