When vacationing in the Dominican Republic, it's best to play it safe. Always avoid drinking local tap water unless your hotel or restaurant has a purified water source. Use caution when consuming ice cubes, fresh salads, and fresh fruit.

Yes, you must exercise significant caution regarding water consumption in the Dominican Republic, as tap water throughout the country is not potable and can lead to severe gastrointestinal illnesses. Tourists are strongly advised to drink only bottled or purified water, which is readily available at all resorts, supermarkets, and convenience stores. Most major resorts provide complimentary bottled water in guest rooms and use purified water for their ice machines, but it is always wise to double-check or ask for "no ice" if you are dining at smaller, local establishments outside the main tourist zones. Additionally, you should use bottled water even for brushing your teeth and try to keep your mouth closed while showering. Be wary of fresh salads or unpeeled fruits that may have been washed in tap water. By sticking strictly to sealed beverages and avoiding any non-purified water sources, you can significantly reduce the risk of "traveler's diarrhea" and enjoy your Caribbean vacation without health interruptions.
