Renting a Pool Villa Long Term on Koh Samui (2026 Guide)

A private pool is one of the biggest reasons people choose a villa over an apartment on Koh Samui — and one of the biggest sources of disputes with landlords, because Thai law simply does not spell out who is responsible for it. If you are looking at a koh samui pool villa long term rental, the practical questions that matter most are rarely covered in the lease template: who pays for pool chemicals, who calls the electrician when the pump fails, and who checks the electricity bill before you move in.

This guide walks through what to expect on cost, maintenance responsibility, the handover process, and pool safety — using current market estimates and the general legal framework that applies, since there is no villa-specific law to fall back on.

Typical rents for a pool villa on Koh Samui

Based on our local team's ongoing contact with the island's rental market as of September 2026, pool villas typically start at around 60,000–70,000 THB per month and rise to 150,000–200,000 THB or more for larger or higher-end builds, depending heavily on size, finish, and how loosely a listing uses the term "pool villa" (a small plunge pool and a full resort-style pool both get marketed the same way). For comparison with apartments and standard houses, see our full breakdown in long-term rental prices on Koh Samui.

Who is responsible for the pool, garden and repairs?

Thailand has no pool-villa-specific rental law. What applies instead is the general rental framework in the Civil and Commercial Code (Sections 537–571), under which a landlord is generally responsible for maintaining the property and for major repairs, while day-to-day upkeep is commonly assigned to the tenant by the contract itself. In practice, the split between landlord and tenant for pool cleaning, gardening and appliance servicing is a matter of negotiation and what your specific lease says — not something set by statute.

Since September 2025, a consumer-protection notification from Thailand's OCPB adds extra protection for tenants renting from a landlord who operates three or more residential units as a business: it is meant to stop tenants being billed for normal wear and tear, and to prevent marked-up utility charges. This rule does not apply to a private individual who owns and rents out a single pool villa — which describes most villa landlords on Koh Samui. Our guide to Thailand's 2025 rental law covers this distinction in full.

In practice, and regardless of what the OCPB rule technically requires, private villa owners on Koh Samui commonly charge tenants 7–10 THB per kWh for electricity — noticeably above the state PEA tariff — based on our local team's ongoing contact with the market. Ask for the exact per-kWh rate in writing before you sign, and request a recent electricity bill if the landlord has one.

Pool service, gardening and pool electricity: what they typically cost

None of the figures below come from an official price list — Koh Samui has no published, government-set rate for these services. They are market estimates gathered from property managers and pool-service providers, and can vary noticeably with villa size, pool size and how far the property sits from town.

Before agreeing a price with any provider, get two or three quotes locally — the range above is wide enough that a single quote tells you very little. It's also worth clarifying upfront in the lease whether the landlord arranges and pays for pool and garden service directly (common, since it protects their own asset) or whether it's the tenant's cost and choice of provider.

Air conditioning and appliance maintenance

Air conditioning follows a similar pattern to the pool: there is no statutory rule dictating who pays for what, so the contract does the work. The common-sense split that most landlords and tenants land on is that routine servicing (filter cleaning, gas top-ups from ordinary use) sits with the tenant, while a compressor failure or another major repair is the landlord's cost as part of maintaining the property under the Civil and Commercial Code. Get this written into the lease explicitly rather than assuming it — "who pays for AC repairs" is one of the most common landlord-tenant disagreements on the island.

The handover checklist

A written handover record with photos is standard good practice on Koh Samui, even though it isn't a legal requirement. Do this together with the landlord or their agent on move-in day, and again on move-out:

• Photograph the pool, garden, and all rooms, noting any existing damage or wear
• Record electricity and water meter readings, with photos of the meters themselves
• Test the pool pump, filter and any pool lighting, and note whether they work
• Test every air conditioning unit and note its condition
• Check that gates, doors and window locks close and lock properly
• Make an inventory list of furniture and appliances included with the villa
• Get both parties to sign and date the handover record, and keep a copy

Pool safety: there is no legal requirement for a fence

If you are renting with young children, it is worth knowing upfront that Thailand has no legal requirement for a pool fence or self-closing gate around a private rental villa's pool. Thailand's Department of Disease Control has published general recommendations on drowning prevention around pools, but these are guidance, not enforceable rules for private landlords. In practice, this means pool safety for children is entirely something you need to negotiate and verify yourself: ask specifically about fencing, gate locks and alarms when viewing, and don't assume a villa marketed as "family-friendly" has any of these features unless you see them yourself. Families settling in more broadly may also find it useful to read alongside our guide on living on Koh Samui with kids.

Deposit and getting your money back

Deposit rules for a pool villa follow the same framework as any other long-term rental on Koh Samui — see our guide to Thailand's rental law for the current caps and refund timelines that apply depending on the size of your landlord's rental business. For a villa specifically, it's worth agreeing in writing, before you move in, how normal wear on pool tiles, garden plants and outdoor furniture will be assessed at move-out, since these are exactly the items that tend to cause disagreements over a security deposit.

Pool villa checklist before you sign

• Get the exact electricity rate per kWh in writing
• Clarify who arranges and pays for pool service, gardening and AC servicing
• Ask about pool fencing, gate locks or alarms if you have young children
• Do a full photographed handover with meter readings before moving in
• Confirm how wear on the pool, garden and outdoor furniture will be assessed at move-out
• Get two or three independent quotes for pool and garden service before assuming the landlord's price is standard

Once the villa itself is sorted, our first-30-days checklist and guide to setting up utilities and internet cover what typically comes next.

Frequently asked questions

Who pays for pool cleaning on a rented villa in Koh Samui?

There's no law that decides this — it depends on your lease. In practice it is usually negotiated between landlord and tenant, with many landlords arranging and paying for pool service themselves since it protects their asset, and others passing the cost to the tenant.

How much does pool and garden maintenance cost per month?

According to our local team, pool service starts at about 2,500 THB a month and rises with pool size, and a plain lawn cut on one rai (1,600 m²) costs about 1,500–2,000 THB, more if clearing up or tree cutting is included. Always get a couple of local quotes rather than relying on one figure.

Is my landlord required to install a pool fence if I have children?

No. Thailand has no legal requirement for pool fencing at a private rental villa. If pool safety for children matters to you, you need to check and negotiate this directly with the landlord.

Can my landlord charge me extra for electricity because of the pool pump?

A pool pump does add a real cost, typically an extra 2,500–5,000 THB a month in electricity. Private villa landlords commonly bill electricity at 7–10 THB per kWh rather than the government tariff — ask for the exact rate before signing.

Do I need a written handover record for a pool villa?

It isn't legally required, but it is strongly recommended. A dated, photographed handover covering the pool, garden, meters and appliances is the best protection for both sides when it comes to returning the deposit.
