Water Dispensers or Plastic Bottles in Thailand: Which Is More Cost-Effective? A Thorough Comparison for Residents

When Japanese people start living in Thailand, a common concern is "how to get drinking water."
Unlike Japan, where it's common to drink tap water as is, in Thailand it's typical to prepare separate drinking water at home or in condominiums.
Especially in Bangkok,
- Water dispensers
- Bottled water
- Home delivery bottled water
- Water purifiers
and other options are available.
So, which one suits the Japanese lifestyle best?
This time, we will thoroughly compare water dispensers and bottled water for residents in Thailand.

Reasons for separate drinking water in Thailand
In Thailand, water conditions vary depending on the region and building.
Therefore, many people prepare drinking water separately.
Common reasons are as follows:
- Concerned about the taste and smell of tap water
- Concerned about old piping
- Worried about drinking water for babies and children
- Don't want to get an upset stomach
- Want to feel safe, just like in Japan
Choosing drinking water directly affects comfort in Thai life.

Families
If you use a large amount daily, the convenience of a water dispenser may outweigh the cost.
However, be sure to check the monthly fee, bottle cost, electricity bill, and delivery fees.

Whichever you choose, how you use it is important.
