Changing bath, toilet and washbasin in fully tiled bathroom

My main bathroom walls are fully tiled floor to ceiling as is the bathroom floor

The washbasin, pedesal, toilet and bath are bit dated now and thinking of changing them

Does anybody know or had experience of just changing the washbasin, toilet and bath in fully tiled bathroom

Is this something that plumber can easily do or am i looking at them going to have to break existing tiles to remove the units and fit new ones and looking at re tile of whole bathroom as well as changing the units (dont have any spare tiles that could use if existing ones got broken)

Any other options to changing the units. Someone mentioned about painting them but never heard of this - anyone know about this

Thanks

Was the washbasin, pedesal, and toilet removed before the tiles were layed in the first place? If so there should be no problems..

Never ever heard of people painting bathroom ware. When the bath is removed, the first row of tiles resting on the bath (and making the seal) will have to be removed and replaced when new bath is fitted. If the room was tiled prior to toliet and WHB being fitted then refitting new ware is easy.
