I wish more developers understood this very basic concept instead of introducing layers of unnecessary complexities in the specs and plumbing that don't necessarily improve a sink or shower "for the better". If you're installing lots of sinks and showers, it's OK if you make the pipe fittings, materials, and plumbing a bit easier to work with. Coming up with dozen of all all new sets of pipe fittings, materials and plumbing designs every other week doesn't make installing sinks and showers easier. Imagine walking into Home Depot and discovering there are about 100 'standard' styles of sinks, faucets, fixtures, pipes, fittings, etc. all with varying degrees of support from none to complete for interoperability. Not only that, every other month, 10 of each of those pieces are no longer manufactured or supported and 20 complete new designs are created with all the same cavets as before. Meanwhile, you install these sinks daily and the customer really doesn't care at all about how elegant the back pieces are from a mathematical or structural view, they just want a functioning sink that they can assume is easy to fix or replace parts on when it breaks. Not only that, they want to be able to call any plumber and have that done without the plumber spending 2 weeks just figuring out what the hell the previous plumber did before they figure out just how to fix it. At which point they decide its easier to just rip everything out, set it on fire, and pick the latest sets of pipes and fittings for no necessarily justifiable reason than it will cost more in time and effort to deal with the previous sink install than to start from scratch.
