There are quality modern baths out there, they need to be properly supported when you fit them to stop a lot of flexing. Seems like you would be making a mistake to go for roll top, if it's not just an occasional guest bathroom in your mansion you would be better off with a modern bath/shower that's compact and easy to keep clean.
You have to be a bit practical about bathrooms and kitchens, if they are only small rooms you can spend good money on tiles and flooring and they will feel luxurious. Think 5 star inner city hotel rooms.
It doesn't exist yet - we're trying to find a solution that works. Modern baths that we've seen look a bit shit though. Want something solid that's not going to flex when you get in.
