🗓 Last updated: February 2026 — SAT registration, FBA rules and trainer permit requirements updated

Drive along the main road through Chalong on a Tuesday morning and you will see it everywhere: Western fighters, Japanese tourists, Thai teenagers, and middle-aged European men all sweating through pads in open-sided gyms. Phuket has been the world's Muay Thai destination since before most of the island's current expat residents were born. Tiger Muay Thai, Phuket Top Team, and Dragon Muay Thai are internationally recognised brands. And every year, someone new arrives thinking: I can build a better gym.

Sometimes they are right. But the market is more competitive than it looks, the legal requirements are more layered than most people expect, and getting the trainer relationships wrong is the fastest way to build a gym with no soul — and no clients. This is the honest guide to doing it properly.

Key Facts at a Glance

  • FBA restriction: Sports/fitness service — max 49% foreign ownership without FBL or BOI
  • SAT registration: Sports Authority of Thailand registration required for commercial operation
  • Trainer work permits: Required for all foreign trainers — no tourist visa instruction
  • Best areas: Chalong (established fight hub), Rawai/Nai Harn (community), Kamala/Bang Tao (premium)
  • Typical startup cost: THB 1,500,000–5,000,000+
  • Biggest success factor: Your Thai master trainer relationships — not your business plan

The FBA Structure Question

Muay Thai gyms are sports and fitness service businesses, classified under Schedule 3 of Thailand's Foreign Business Act. The standard restriction applies: foreign nationals cannot own more than 49% without a Foreign Business Licence (FBL) — which is rarely granted for this type of business.

The two realistic options for expat gym owners:

Thai-Majority Company

The standard approach in Phuket's gym market. Thai nationals hold 51%+ of shares; the foreign operator holds up to 49% and obtains a work permit as 'sports facility manager' or 'Muay Thai instructor'. This is by far the most common structure — including at many of Phuket's most well-known gyms. Your Thai co-shareholders should be genuine participants — a Thai business partner who knows the local market and has connections with trainers is genuinely valuable, not just a legal necessity.

BOI-Promoted Sports Tourism Business

Thailand's BOI has a sports tourism and wellness category that can accommodate Muay Thai training camps meeting specific investment thresholds (typically THB 1–3 million+ in qualifying investment). BOI promotion allows 100% foreign ownership and comes with additional benefits. See the Phuket BOI guide for qualifying criteria.

Sports Authority of Thailand Registration

Commercial Muay Thai gyms should register with the Sports Authority of Thailand (SAT), specifically through the Phuket regional SAT office. SAT registration establishes your gym as a legitimate sports facility and is relevant to:

The SAT registration process involves a facility inspection against sports facility standards: ring specifications (full-size competition ring: 6.1m x 6.1m inside ropes minimum), adequate training floor space, safety padding, ventilation, first aid equipment on-site, and adequate changing and shower facilities. Allow 4–8 weeks and budget THB 2,000–5,000 in government fees plus any facility upgrades required to pass inspection.

Ring and Equipment Specifications

The ring is your single most visible quality signal. Tourists and serious fighters judge a gym's legitimacy by its ring before anything else. Phuket-quality training rings that will pass muster:

The Trainer Question: The Heart of Your Gym

Your Thai master trainers are not an operating cost. They are your product. A Muay Thai gym without respected, experienced Thai masters is a fitness class with Thai pads — it is not Muay Thai. This is the non-negotiable truth of the market.

Finding and Retaining Thai Trainers

Experienced Muay Thai trainers with strong English and international client skills earn THB 25,000–55,000/month at Phuket's established gyms. Younger trainers with fighting backgrounds but less English: THB 15,000–25,000/month. The Chalong and Kathu areas have the densest pool of available talent, but the best trainers have their pick of employers — they will evaluate your gym's culture, management style, and training environment as much as the salary.

Trainer retention is harder than acquisition. High turnover of Thai trainers destroys a gym's reputation. Provide trainers with genuine respect, cultural sensitivity, health insurance, and career development opportunities (trainer certification support, international seminars). Gyms that treat Thai trainers well build loyalty that money alone cannot buy.

Foreign Trainer Work Permits

Any foreign national instructing at your gym — Muay Thai, strength and conditioning, yoga supplementary — needs a work permit specifying their role at your company's address. This is actively enforced in Phuket. Work permit applications go through the Department of Employment in Phuket Town. See our Phuket work permit guide for the full process. Budget THB 15,000–25,000 per permit annually (government fees + lawyer costs).

Get the Right Health Insurance for Your Trainers and Staff

Muay Thai trainers sustain occupational injuries. Proper group health insurance with Bangkok Hospital Phuket network access is both an ethical obligation and a trainer retention tool. Cigna offers competitive group plans for sports businesses.

Business Models: Camp vs Gym vs Hybrid

Phuket's Muay Thai business models have evolved significantly. The main structures in 2026:

ModelDescriptionRevenue per StudentStrengthsChallenges
Training camp (residential)Accommodation + training packages; students live on-site for 1–8 weeksTHB 15,000–45,000/week all-inHigh revenue per student; captive audienceHigh capital; accommodation management
Day-class gym (non-residential)Morning and evening class schedule; daily/weekly/monthly passesTHB 400–800/session or THB 8,000–18,000/monthLower setup cost; simpler operationsRequires strong local/tourist base
Professional fight teamSupporting active Thai and international fighters; competition focusRevenue through fighter sponsorship, fight feesReputation and credibility buildingLow direct revenue; requires serious training environment
Hybrid (training + gym + wellness)Combines Muay Thai with fitness classes, yoga, massage, nutritionHigh — cross-sell and upsell opportunitiesYear-round revenue streams; diverse clienteleComplex management; multiple licence requirements

The most financially resilient model in Phuket combines day-class access with some residential camp capacity and a wellness component. Pure residential camps are vulnerable to seasonal dips and the challenge of consistently filling accommodation. Day-class gyms are more resilient but require consistent marketing to drive walk-in and repeat business.

Location Strategy

Chalong (Soi Yodsanklai area)

The global brand hub of Phuket Muay Thai. Tiger Muay Thai, Phuket Top Team, and Dragon Muay Thai all operate here. The Chalong location carries inherent credibility with serious fighters who travel to Phuket specifically for this cluster. Rent: THB 50,000–200,000/month for suitable spaces. Competition is intense but the market is genuinely large and world-class.

Rawai and Nai Harn

A community-oriented market with long-stay expats, retirees, and health-conscious tourists who prefer a smaller, less tourist-factory environment. Lower rent (THB 25,000–70,000) and a loyal repeat student demographic. Suits a quality-focused gym with smaller class sizes and a reputation for skilled individual instruction.

Kamala and Bang Tao

Premium pricing opportunity targeting high-spend tourists from the Laguna and Andamanda resort area. Smaller-class, private-session model with higher per-session rates (THB 1,500–3,000 for private sessions). Lower volume but higher margins. Works well as a secondary or boutique gym.
