Let’s get practical. Taste: Tap water has character (or funk). Distilled water is dull.
Safety: Both are safe to drink in most places. Tap water is regulated. Distilled water is too regulated—by the laws of physics. No bugs, no minerals, no worries.
Price: Tap water is basically free. You pay a tiny bill. Distilled water costs money. You buy it in jugs or boil your own. It’s the fancy water that does nothing fancy.
Best uses: Tap water for drinking, cooking, and brushing your teeth. Distilled water for steam irons, car batteries, fish tanks, and CPAP machines. Your plants won’t thank you for distilled water, by the way. They need those minerals.
