Scuba diving cost in Thailand & Koh Tao (2026)
Koh Tao certifies more divers than almost anywhere on Earth, and the price is the reason. Here's the real, all-in cost of learning to dive in Thailand.
If you ask experienced divers where to get certified on a budget, one answer comes up again and again: Koh Tao. This small island in the Gulf of Thailand certifies a staggering number of new divers every year, and the reason is simple — volume drives prices down, and the diving is genuinely good. Here's what it really costs in 2026.
Open Water certification on Koh Tao
Koh Tao is famous for some of the lowest Open Water prices anywhere. A verified all-in Open Water course on the island typically sits around ฿11,000–฿12,000 (roughly €290–€320, depending on the exchange rate). That usually includes training, materials and certification — but always confirm what's bundled.
Verified Koh Tao pricing
Open Water on Koh Tao runs about ฿11,000–฿12,000 all-in. Because so many centers compete on the same small island, the headline prices are unusually honest — but gear, accommodation deals and fun-dive packages still vary. See current verified prices on our Koh Tao page.
Fun dives and continuing education
Already certified? Koh Tao is also a bargain for fun dives, with multi-dive packages bringing the per-dive price down further. It's a popular place to continue to Advanced Open Water or even start a professional path (Divemaster), partly because the cost of living and training is so low.
| Open Water Diver course | ฿11,000–฿12,000 |
| Fun dives | best value in multi-dive packages |
| Advanced Open Water | popular, competitively priced |
What Koh Tao prices usually include — and what to check
- Training, instruction and the four open-water dives are standard.
- Materials and certification are usually included on Koh Tao — but confirm in writing.
- Some centers bundle a few nights' accommodation with courses — great value if you need a bed anyway.
- Check whether gear rental is included or extra.
- Marine and boat conditions are seasonal; ask about the best months for your dates.

How Koh Tao compares to the Red Sea
Both are excellent value, but for different reasons. Koh Tao wins on raw course price thanks to fierce competition and low costs. Egypt's Red Sea is closer for European travellers and offers spectacular reefs and wrecks, though its diving tax nudges prices up. Neither is 'better' — it depends on your route and budget.

The DiveCost approach to Koh Tao
Koh Tao's prices are unusually transparent already — but 'unusually transparent' still isn't 'all-in'. We label what's included and date every price so you compare like for like.
Bottom line: if your priority is the lowest possible certification cost with solid quality, Koh Tao is hard to beat. Just confirm what's bundled, and budget for the all-in number.
