Renovating a property in Phuket is equal parts exciting and humbling. The labour costs are genuinely cheap by Western standards, the craftsmanship of skilled Thai tradespeople can be exceptional, and the materials markets in Phuket Town and along Chao Fa Road stock everything from Italian tiles to bespoke teak joinery. But the island also has a thriving ecosystem of middlemen, rushed quotes, permits that nobody mentions until it's too late, and rainy-season delays that can stretch three weeks of work into four months.
This guide is for expats who have bought or are renting a house or villa in Phuket and want to renovate — whether that's a bathroom update in Rawai, a pool and terrace in Chalong, or a complete interior overhaul in Bang Tao. We cover realistic costs, how to find and manage contractors, permits, and the common mistakes that cost people real money.
How Much Does Home Renovation Cost in Phuket?
Renovation costs in Phuket span a huge range depending on the scope, finish level, and who you hire. Here are realistic 2026 benchmarks.
| Renovation Type | Cost (THB per sqm) | Notes |
|---|---|---|
| Basic cosmetic (paint, flooring, fixtures) | 5,000–10,000 | Tile work, painting, basic joinery |
| Mid-range interior renovation | 10,000–20,000 | New kitchen, bathrooms, electrics |
| High-end villa renovation | 25,000–50,000+ | Imported materials, custom joinery, smart home |
| New kitchen (standard) | 150,000–400,000 THB total | Thai-made cabinets, standard appliances |
| New kitchen (high-end) | 500,000–1.5M+ THB total | European brands, island bench, built-in appliances |
| Bathroom renovation (standard) | 60,000–150,000 THB total | New tiles, toilet, shower, vanity |
| Bathroom (luxury) | 200,000–500,000+ THB total | Freestanding bath, imported fittings |
| Pool construction (standard) | 800,000–1.5M THB total | 6×3m concrete, basic finishes |
| Pool renovation / resurfacing | 200,000–450,000 THB total | New plaster, tiles, equipment |
| Roof replacement (standard) | 300–600 THB/sqm | Thai tiles or metal sheet |
| Air conditioning installation | 25,000–60,000 THB/unit | Split system including installation |
| Solar panels (3–5kW system) | 200,000–380,000 THB | Installed, with grid tie-in permit |
Always add 20–30% contingency to any renovation budget in Phuket. Hidden structural issues, material price fluctuations, and scope creep are the norm, not the exception. The more you uncover an older property, the more surprises you'll find — especially around plumbing and electrical in houses built before 2010.
How to Find and Vet Contractors in Phuket
This is where most renovation horror stories begin. Phuket has excellent contractors and deeply unreliable ones, and the two categories are not always easy to distinguish before you hand over a deposit.
Get referrals, not cold quotes
The single most reliable approach is referral from someone who has recently completed a similar project. Phuket's expat Facebook groups — Phuket Expats, Rawai Expats, Bang Tao Community — regularly see renovation discussions and recommendation requests. Post your project type and ask for recommendations; you'll typically get 5–10 genuine referrals with contact details and photos of completed work.
Always visit completed projects
Before committing to any contractor for work over 200,000 THB, ask to visit at least two completed projects. This is normal and any reputable contractor will arrange it. Look specifically at tile grouting, door and window fitting, external rendering (mould and cracking are Phuket's two most common defects), and bathroom waterproofing. Bad waterproofing in Phuket's humidity is catastrophic and expensive to fix.
Get three written quotes — itemised
Verbal quotes are almost worthless. Require written, itemised quotes that specify materials (brand, grade, quantity), labour rates, timeline milestones, and payment schedule. A contractor who won't provide an itemised quote is telling you something important about how they'll manage your project.
Payment structure
Never pay more than 30% upfront. A professional contractor will accept a 30% deposit, with further payments tied to milestone completions (e.g. 20% on structural completion, 20% on rough fit-out completion, 20% on final fit-out, 10% on defects snagging completion). Contractors who ask for 50% or more upfront should be treated with significant caution.
Watch for: requests for more than 30% upfront; no written contract; no itemised materials list; inability to provide references; reluctance to obtain permits ("we never bother for small work"); subcontracting to a crew you never met; dramatic price increases once work has started. These patterns appear repeatedly in Phuket renovation disputes.
The Renovation Process: Step by Step
Define what you want to achieve with a clear brief. Separate "must have" from "would like." Set your budget including a 25% contingency reserve before approaching contractors.
For any structural work or a renovation over 500,000 THB, hire a local architect. They handle permits, provide drawings contractors can build from, and can supervise independently — worth the 5–10% of project cost.
Your architect files with the relevant local administration (OrBorTor or Phuket City Organisation depending on location). Standard permits take 30–60 days. Don't start structural work without approval.
Get three itemised quotes. Visit completed projects. Check references. Negotiate payment milestones and have a lawyer or your architect review the contract before signing.
Visit the site daily if you're in Phuket. If you're remote, hire a project manager (your architect can often do this). Take dated photos of all stages. Issues caught early are far cheaper than discovered at completion.
Create a formal snagging list before your final payment. Hold 5–10% of the total project cost until all defects are corrected. Professional contractors will accept this — non-professionals will resist it.
Permits, Planning, and Legal Considerations
When do you need a permit?
Building permits (ใบอนุญาตก่อสร้าง) are required in Phuket for new construction, structural modifications (removing or adding walls), extensions, changes of use, and installations of specific types (including septic systems). Cosmetic work — painting, flooring, replacing like-for-like fixtures — generally doesn't require a permit. When in doubt, ask a local architect; the cost of a consultation is trivial compared to the fine for unpermitted structural work.
Who issues permits in Phuket?
Within Phuket City: Phuket City Municipality (เทศบาลนครภูเก็ต). Outside city limits: the relevant Tambon Administration Organisation (OrBorTor / อบต.) for your area. Properties in some development zones have additional restrictions under their juristic person rules — check your property's chanote (title deed) documentation.
Foreign ownership constraints
Foreigners cannot own land in Thailand but can own the structure. If you're renovating a property under a lease arrangement — common for expats — your renovation rights depend entirely on what your lease contract says. Have a Thai property lawyer review your lease before starting any significant renovation. Some leases explicitly prohibit structural modification; others grant full rights to the building. Don't assume.

Timing Your Renovation: Dry Season vs Wet Season
Phuket's wet season (roughly May–October) significantly affects renovation timelines and costs. Here's what to plan around:
Dry season (November–April)
Ideal for exterior work — roofing, rendering, external painting, pool construction, landscaping. Contractors are in higher demand during this period; book early and expect less flexibility on start dates. Materials deliveries are faster and concrete curing is more predictable.
Wet season (May–October)
Interior renovation — kitchen, bathrooms, electrics, flooring, joinery — proceeds fine in the wet season. External work will be interrupted regularly. If your project has both interior and exterior components, smart scheduling puts exterior work in the dry season and uses the wet season for interior fit-out. Contractor availability is better and some will offer slightly lower rates in the quiet months.
Phuket's humidity makes mould a serious consideration in any renovation. Use anti-mould primers as standard on all interior walls. External renders need a quality waterproof topcoat, not just paint. Grout lines in wet areas must be sealed after laying. Bathrooms need positive pressure ventilation — not just an air gap. Getting this right at renovation stage is vastly cheaper than treating the consequences later.
Where to Buy Materials in Phuket
Phuket's building materials market is better stocked than most expats expect. Here's where to source what you need:
Tile and ceramics
The Chao Fa Road industrial area in Phuket Town is home to multiple large tile showrooms stocking Thai, Italian, and Spanish tiles at all price points. For designer or large-format tiles (1200×600mm and above), Kaveepong and Pacific Tile on Chao Fa Road are well regarded. Thai-made tiles are excellent quality and a fraction of imported prices for standard sizes.
Hardwood and joinery
Teak, merbau, and treated hardwoods are available locally. Phuket Town's woodworking district along Ong Sim Phai Road has traditional carpenters producing quality bespoke joinery — particularly shutters, door frames, and furniture. Prices are dramatically lower than imported equivalent work.
Plumbing and sanitary ware
Home Pro and Global House (both on the bypass road near the airport and near Central Festival) carry Thai and imported sanitary ware. For higher-end European brands (Grohe, Hansgrohe, Geberit), Bangkok-based suppliers ship to Phuket within a week; prices are significantly lower than buying locally at premium retail.
Electrical
Always use Thai-standard electrical components (220V, 50Hz). Attempting to import foreign electrical fittings to reduce costs creates inspection issues and insurance problems. Local electrical wholesalers on Tilok Utit and Phang Nga Road in Phuket Town carry commercial-grade stock.
Need to transfer money for your renovation?
Transferring renovation budgets into Thailand with Wise saves significantly on bank exchange rates and fees. Most expats use it for large contractor payments.
