Well I can't agree with that point of view, but I see what you're getting at. However, there's always a compromise, and wall hung toilets and sinks look great (in my opinion), but at a cost... you have to hide the plumbing. Plumbing is ugly and detracts from the clean look - you can't have it both ways... unfortunately.
I'm making it as accessible as I possibly can anyway. It won't be as bad as the marble disaster - although if you can afford 50k for some marble tiles, I doubt the re-tile really hurt his budget - if he has a budget.
Worst case for me is taking some tiles and plasterboard down - I better keep some spares ! The cistern is accessible through an access panel behind the flush panel though... it's not all bad!
Had to repair a leak on one of those a few weeks back, pan connection at rear started to leak after 3 years(fitted by others) Soil water was running down pipework in Lounge boxing. Nightmare job, remove tiles, boarding etc.
Insurance job, new carpet etc. Replacement tiles don't match the rest of the bathroom anymore, so hey good luck, but always look up at the ceiling, cos you never know.
