Living in Koh Samui: Schools, Healthcare & Cost of Living (2026)

Plenty of people arrive on Koh Samui for a holiday and start quietly wondering what it would be like to stay. Before that daydream becomes a property search, it helps to know the practical reality of living here: the schools, the healthcare, what it actually costs each month, and the visa routes that let you stay long term. This guide gives you the honest picture for 2026.

What Is Healthcare Like on the Island?

Better than most people expect for an island. Koh Samui has five hospitals, anchored by Bangkok Hospital Samui, an internationally accredited private facility with over 25 specialist physicians, English-speaking staff, and modern equipment, alongside Samui International Hospital and a network of clinics. Care is both accessible and affordable by Western standards: a doctor's consultation typically costs between 200 and 1,500 baht (often around USD 14 including basic medication), and it is common to be seen by a specialist within the hour at a private hospital. Dental and optical care are high quality and inexpensive, which is part of why Thailand is a medical-tourism destination. Most expats carry private health insurance, with premiums commonly starting around 86,000 baht (roughly USD 2,500) a year depending on age and cover. For anything highly specialised, Bangkok's flagship hospitals are a short flight away.

Are There Good Schools for Families?

Yes, which is what makes the island viable for families rather than just retirees and couples. The International School of Samui (ISS) offers the Cambridge curriculum, with annual fees in the region of 350,000 to 500,000 baht. There are several other international and bilingual schools across the island catering to the expat community. For university, students typically head to the mainland or Bangkok, though there is a tourism-and-hospitality-focused international school on the island itself. For most school-age children, the island's options are genuinely sufficient.

What Does It Cost to Live Here?

This depends heavily on how you live, and it is worth being honest about the range. At the modest end, expats report living comfortably from around USD 1,500 a month. A more typical comfortable lifestyle sits higher, and a genuinely luxury monthly budget, larger sea-view villa rental, dining out, help around the house, runs in the region of 150,000 to 250,000 baht (roughly USD 4,150 to 6,950) a month.

Housing is the biggest variable. Long-term rentals are far cheaper than buying: a one-bedroom apartment typically runs 8,000 to 15,000 baht a month, while a luxury sea-view villa on a long lease might be 60,000 to 120,000 baht a month. Everyday costs are low, a meal at a local Thai restaurant is 50 to 120 baht, while imported goods and international restaurants cost much closer to Western prices. The trick most long-termers learn is to live somewhat locally rather than importing your home country's habits.

How Do You Get On and Off the Island?

Koh Samui has its own international airport, with Bangkok Airways operating direct flights to Bangkok (about an hour), plus Singapore and Kuala Lumpur, and residents get discounts. There are also car and passenger ferries to the mainland at Surat Thani, and connections to neighbouring Koh Phangan and Koh Tao. A 31-mile ring road makes getting around the island straightforward. The connectivity is a genuine quality-of-life factor and a big part of why the northeast (near the airport) is so desirable.

Which Visa Lets You Stay Long Term?

This is where you need current, careful advice, because Thai visa rules change and 2026 has seen several updates. The main routes for property buyers and long-stayers are:

Retirement visa (Non-O / O-A): for those aged 50 and over, requiring either 65,000 baht per month in income or 800,000 baht held in a Thai bank account. The most common route for retirees.

Long-Term Resident (LTR) visa: a 10-year visa aimed at wealthier residents, requiring annual income of at least USD 80,000, or USD 40,000 combined with investment in Thai property. It includes work-permit benefits and a 17% flat-tax option, making it attractive for higher earners.

Destination Thailand Visa (DTV): launched in 2024 for remote workers, allowing stays of up to 180 days per entry over a 5-year validity, requiring proof of 500,000 baht in savings and employment with a foreign company.

Thailand Privilege (formerly Elite) visa: a membership-based long-stay visa requiring a substantial one-off fee, popular with those who want a straightforward long stay without the income tests.

One important 2026 note: health insurance is mandatory for several visa categories (commonly a minimum of 400,000 baht inpatient cover), and the rules around entries and digital arrival registration have tightened. Always confirm the current requirements with a qualified visa agent or lawyer before committing.

What About Tax?

Worth flagging honestly because it changed recently. As of 2024, spending 180 or more days in Thailand in a year makes you a Thai tax resident. And in 2026, foreign-sourced income remitted into Thailand is generally treated as taxable, unless you can show the funds were earned before 1 January 2024. Rental income from a Thai property is taxable too (non-resident owners face a 15% withholding rate, Thai tax residents 5%, with progressive rates on filing). This is not a reason to be put off, but it is a reason to get proper cross-border tax advice before you move, rather than after.

So, What Is Living Here Actually Like?

For many, very good. You get a tropical island with real infrastructure, a sizeable and sociable international community (which swells toward 40,000 in peak periods), good healthcare, viable schooling, easy regional travel, and a cost of living that, lived sensibly, stretches further than back home. The trade-offs are the practical ones of island life, a monsoon season, occasional connectivity hiccups, and the need to stay on top of visa and tax paperwork. But as a place to base a life rather than just a holiday, Koh Samui genuinely works.

If you are weighing up a move and thinking about buying rather than renting long term, the lifestyle and the property decision go hand in hand, which area suits your life here shapes which property makes sense.
