From what I have seen, when it comes to plumbing fixtures, you never can tell what is outdated. As long as a plumbing fixture does its job in an efficient way, it could be in or out, depending on the current design trends.

But, plumbing fixtures are not really outdated for good in most cases.

I believe this is the case with standard spout kitchen faucets. Like you mentioned, many people enjoy the look and the operation of a standard spout kitchen faucet with a remote spray head over the pull-out or pull-down models.

With this in mind, faucet makers have made updates to keep standard spout faucets trendy. Some changes are sleek one-handle designs with high-arch swinging spouts, state-of-the-art ceramic disk valves and water-saving aerators.

Bottom line: Standard spout kitchen faucets are far from being a washed-up plumbing fixture.
