Is the warm water dial/handle always on the left side in a shower, tub, or sink?

    The US Universal Plumbing Code specifies that the hot water tap be on the left side as you face the fixture. You do find that occasional anomaly where someone has worked on the fixture and reconnected it incorrectly.

    In the special case of the single handler shower/tub controls, the COLD water always comes on FIRST. The further you turn the control, the more hot water you get. If you encounter one that behaves differently, I would say you have found one that is connected incorrectly.

      Uniform, not universal. A mere slip of the keyboard. In the meantime, educate yourself: http://www.iapmo.org/Pages/IAPMOgroup.aspx

    No, not "always". But that is the general rule in most countries I have ever visited. Also, consider that many showers, tubs or sinks have only a central dial or handle, making your question inapplicable.

    Of course.

    It is a standard rule. But the owner could reverse them if he desires. Here is something to think about. The hot water side will always be guaranteed sterilized, even when cold, when it comes out of the faucet as long as the hot water heater is working and set above 170degrees!

      Setting a "hot water heater" [sic] or delivering water at the tap at above 135F would be a code violation in many places.

    If you hold your plumber upside down it will be on the right.

    In the US, that is the standard.

    In actual practice, it is possible to install plumbing with the hot water supply on either side.

    That is the industry standard. But the water lines can be hooked up so hot is on the right, cold on the left.

    while the north american standard is hot water on the left, not all are actually that way [usually because a home plumber did the work]
