Self-service coin laundry near Mae Haad and Sairee, wash-by-kilo drop-off shops, real THB pricing, and an honest note on why dedicated dry cleaning isn't available on the island.
Koh Tao's laundry scene is genuinely informal -- there's no island-wide chain the way Bangkok has Otteri or Wash Coin. Shops are identified by landmark rather than brand: next to a particular vegetable stall, near a supermarket, along a stretch of road between Sairee and Mae Haad. That's not a research gap, it's simply how the island's small businesses operate. Here's what's actually there, what it costs, and an honest note on the one service that doesn't exist locally.
The largest self-serve station sits next to the Chumporn Fresh Mart vegetable stall, near ChaiWat Supermarket, on the main road between Sairee and Mae Haad -- an 8kg machine runs THB 50 and a 14kg machine THB 80 per cycle. A smaller self-serve station also sits roughly between Chalok Baan Khao and Mae Haad. Bring your own detergent or buy a sachet on-site; you load, wash and dry it yourself.
Small drop-off laundry shops cluster along the Sairee strip and near the Naypon walking street, charging roughly THB 30-60 per kilogram depending on how close to the main tourist strip you are -- prices drop the further you go from central Sairee toward Chalok Baan Khao. None of these operate under a consistent island-wide brand name; they're independent, informally-run shops identified by their location rather than signage you'd recognise from elsewhere in Thailand.
Most dive resorts and hotels offer their own laundry service, typically THB 40-60 per kilogram -- broadly in line with, or a little above, town drop-off shops. Convenient if you're not leaving your accommodation, but rarely the cheapest option on the island.
An extensive search turned up no dedicated dry-cleaning business on Koh Tao, separate from the wash-and-fold and self-serve options above. If you have a genuine dry-clean-only item, the honest answer is to hold it until you're back on the mainland (Surat Thani or Bangkok) rather than assume a local option exists.
No -- unlike Bangkok's Otteri or Wash Coin, Koh Tao's laundry scene is made up of small, independently-run shops identified by their location (next to a particular vegetable stall or supermarket, along a stretch of road) rather than a recognisable island-wide brand. Ask locally for the nearest current option.

Roughly THB 30-60 per kilogram at drop-off shops, generally cheaper the further you go from central Sairee toward Chalok Baan Khao, plus THB 10-20 per kilogram extra for same-day express. Hotel and resort in-house laundry runs a little higher, around THB 40-60 per kilogram.
Not that could be verified. An extensive search found only wash-by-kilo and self-service laundry options, with no dedicated dry-cleaning business distinct from those. If you have a genuine dry-clean-only garment, plan to deal with it back on the mainland rather than assume a local option exists.
Standard wash-by-kilo drop-off service is typically ready the next day. Same-day express is often available for an extra THB 10-20 per kilogram if you ask up front. Self-service machines are the fastest option if your schedule allows waiting around an hour for the wash and dry cycle.
Laundry locations, pricing and the dry-cleaning gap reflect published traveller and expat sources as of this writing. Small island businesses open, close and relocate without much notice — confirm the nearest current option with your accommodation or dive shop before relying on a specific location.
