Best Private Pool Villas in Koh Samui (2026)

Koh Samui has six hotels with a confirmed private pool that belongs to your villa, and at only one of them – Banyan Tree Samui – does every villa have one. That gap matters more than the rates do: at several of the island's best-known pool-villa resorts, the cheapest category has no pool at all, under a name that reads almost identically. Entry rates start at $221 a night.

Those are entry rates in the villa tier that actually includes a pool – on Koh Samui that distinction is the whole game. Two more confirmed properties sit outside the grid: the Ritz-Carlton for ultra-luxury and Sareeraya on Chaweng itself, both written up below.

Which Koh Samui private pool villa should you book?

Book Banyan Tree Samui. It's tied for the highest guest rating on the island, and it's the only resort here where every villa – all 88 of them – has a 35 sqm private infinity pool as standard. There is no cheaper category hiding without one, no name to decode, no confirmation email to double-check.

On an island where that's the single most common booking mistake, it's worth the rate on its own. Check Banyan Tree dates – 88 villas is the whole property, and December to March goes early.

Then the specialists. Want to walk to dinner instead of ordering a taxi: book Anantara Bophut, at the edge of Fisherman's Village. Watching the budget: book Melati Beach, the cheapest confirmed pool villa on Samui. Want the hillside ocean panorama: book Six Senses – and read the category name twice.

Banyan Tree Samui

Every villa on this property has a pool. All 88 of them, from the entry Ocean View Pool Villa to the Presidential, each with its own 35 sqm private infinity pool – there is no standard hotel room at Banyan Tree Samui, which is genuinely unusual even among the island's other confirmed pool-villa resorts. Whatever you book, you get the pool.

Move up the tiers and the Royal Banyan Ocean Pool Villa, the Family Deluxe and Family Ocean Pool Villas and the Presidential add a separate heated jet pool alongside the infinity pool, plus bigger covered pavilions. The setting is a secluded stretch of Lamai Bay on the south coast, a protected shallow cove that's good for swimming and snorkeling straight off the sand.

The trade is nightlife. Lamai is the quieter of Samui's two main strips, with its own restaurants at a smaller scale, and Chaweng or Bophut is 25–30 minutes by road. If your evenings are the point of the trip, that's a real cost. If they aren't, the south coast is the better side of the island.

Book this one if you want the safest booking on Koh Samui – there is no category here that leaves you without a pool. Check Banyan Tree availability now – it's the pick most readers of this guide should hold, and the dry-season months fill months ahead.

Six Senses Samui

Six Senses is built into a hillside above Choeng Mon on the northeast tip, and the views are the reason to come: villas step down the slope, each with an 18 sqm private infinity pool framing the water. 59 of the resort's 66 villas have one.

The entry Hideaway Pool Villa sits at the top of the property with partial ocean views; Ocean View, Ocean Front and Ocean Front Pool Villa Suite move progressively closer to the sea with larger decks.

Now the trap, and it's an expensive one. The resort's cheapest category is the "Hideaway Villa" – no "Pool" in the name, and no pool on the deck. It reads almost identically to the Hideaway Pool Villa on a booking page. Only the categories with "Pool" in the name include one.

Choeng Mon itself is a quieter beach a short drive from both Chaweng and Bophut, so you're not cut off. Book this one if the hillside ocean panorama is what you're paying for – and confirm the words "Pool Villa" on the reservation. Check Six Senses rates.

Anantara Bophut

This is the one you book to walk out to dinner. Anantara sits at the edge of Fisherman's Village, Koh Samui's most walkable dining and nightlife strip – no taxi, no resort-restaurant fatigue on night three. Nowhere else on this list puts a private pool that close to somewhere worth walking to.

Both pool categories are genuinely private, which keeps it in the low-risk column. The Garden Pool Suite has a 14 sqm private pool set in landscaped gardens; the Beachfront Pool Suite swaps the garden for direct beach frontage and a private plunge pool reached through its own archway. Bophut is on the north coast, roughly 15–20 minutes from the airport.

The rate is the honest catch – from $900, more than double Banyan Tree's entry and by some distance the highest in the grid. You're paying for the address. Book this one if walking to restaurants matters more to you than the size of the pool. Check Anantara Bophut rates.

Melati Beach Resort

From $221 a night, this is the cheapest confirmed private pool villa on Koh Samui – roughly half Banyan Tree's entry rate and a quarter of Anantara's. The Pool Villa is a one-bedroom layout with its own swimming pool and an outdoor sun terrace, and larger tiers – Pool Villa Suite, Family Pool Villa, Presidential Suite – scale up for groups.

It sits on Thongson Bay, a private cove near Choeng Mon that most of the island's traffic never reaches. That seclusion is the appeal and the limitation in the same breath: there's very little outside the resort, and Chaweng is about 15 minutes away by taxi when you want dinner elsewhere.

Book this one if the private pool is non-negotiable but the budget is. Check Melati Beach rates – it's the entry point to this category on Samui, so it's also the first to sell out in the December–March window.

Ritz-Carlton Koh Samui

The Ritz-Carlton holds a private bay across 58 acres of former coconut plantation at the island's northern tip – the largest and most resort-scale property in this guide by a distance. The clifftop Ultimate Pool Villa has an 18 sqm pool with panoramic ocean views and carries the highest confirmed rate on Samui, from around $2,500.

The Exclusive Pool Villa, from $1,200, is the more accessible way into the private-pool inventory, with a separate living area and ocean or resort views.

What the acreage buys is everything else: a Muay Thai ring, tennis courts, and a spa village with eight treatment suites. Choeng Mon's beach is shared with Six Senses nearby, but the Ritz-Carlton's own bay is private.

Book this one if the resort itself is the destination and the rate isn't the constraint. Check Ritz-Carlton Koh Samui rates.

Sareeraya Villas and Suites

Sareeraya is the only confirmed private-pool property directly on Chaweng Beach, Samui's main strip – and it's at the quiet north end, so you get walking access to the restaurants and bars without sleeping above them. From $250, it's also the second-cheapest confirmed pool on the island, and under 2 km from the airport, the shortest transfer here by a wide margin.

Read the category name carefully. The "Villa" category has a private plunge pool (sea or lotus-pond view, subject to availability). The separate "Suite" categories have a terrace or an outdoor Jacuzzi – not a private pool. Same property, same booking page, completely different product.

Book this one if you want Chaweng on your doorstep – and make sure the word "Villa" is on the confirmation. Check Sareeraya rates.

Why the cheapest room at a Koh Samui pool resort often has no pool

It's a topography problem before it's a marketing one. Samui's coast rises fast into hills, so the resorts that trade on views – Six Senses on its slope, the Ritz-Carlton on its clifftop – are built on terraced plots where each pool is its own small engineering job, cut into the hillside and plumbed uphill.

That makes the pool a tier rather than a standard. A resort carves pools into the buildable plots and sells the rest of its rooms without one, which is exactly how you end up with a Hideaway Villa and a Hideaway Pool Villa on the same page.

Banyan Tree is the exception because it committed at the design stage: 88 villas, 88 pools, no other category. And it explains the size differences you see across this list – the flat, walkable, beach-level properties run small plunge pools around 14 sqm at Anantara, while the hillside resorts get the 18 and 35 sqm infinity decks. Flat land near the restaurants is expensive; hillside land isn't.

The same pattern repeats along Thailand's other coasts, at different price points – the private pool villas hub runs the same is-the-pool-actually-yours test on every one. Phuket has the deepest pool-villa inventory in the country, Krabi and Phang Nga put them against limestone karst scenery, and Koh Phangan is the quieter, cheaper neighbor an hour by boat from Samui.

When to go

December to March is Koh Samui's dry season and the best window for a pool villa: low humidity, little rain, calm seas. It's also the busiest, so it's the one to book early.

Here's the part travelers get wrong. Koh Samui sits on the Gulf of Thailand side and runs an inverted monsoon compared with Phuket and the Andaman coast. October and November are Samui's wettest months – precisely when the Andaman side is drying out. If you're planning a two-island trip, the two coasts are rarely at their best in the same week.

April to September is hot but generally dry, with July and August a secondary high season driven by European and Australian travelers. One logistical note: Samui's airport (USM) is small and serves fewer long-haul routes than Bangkok or Phuket, so most itineraries connect through Bangkok – build the extra leg into your dates before you lock the villa.

What to do beyond the pool

A private pool covers the mornings; the water outside the resort covers the rest of the trip. Ang Thong Marine Park is the full-day option, Pig Island and Koh Tan the half-day one, and a jet ski safari, sunset cruise to Koh Phangan or day trip to Koh Tao and Koh Nang Yuan cover the rest of the island's water.
