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 "what to do about drinking water."
Unlike Japan, where it's customary to drink tap water directly, in Thailand, it's common to prepare separate drinking water at home or in condominiums.
Especially in Bangkok, there are various options:
- Water dispensers
- Bottled water
- Delivered bottled water
- Water purifiers
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 preparing separate drinking water in Thailand
In Thailand, water conditions vary by region and building.
Therefore, many people prepare separate drinking water.
Common reasons include:
- Concerns about the taste and odor of tap water
- Concerns about old pipes
- Concerns about drinking water for babies and children
- Want to avoid stomach problems
- Want to feel safe, just like in Japan
Choosing drinking water directly impacts the comfort of life in Thailand.

Family household
If you use a large amount daily, the convenience of a water dispenser may outweigh other factors.
