The Gulf of Morbihan is a small inland sea dotted with islands, between Vannes, the Rhuys peninsula and Locmariaquer. Further west, Carnac lines up its menhirs and Quiberon stretches out facing the ocean. The seawater stays cool: the thalasso centres of Quiberon and Carnac, the spa hotels of Vannes and the long stone farmhouses with indoor pools around Auray take over. I've selected 25 places, all rated at least 8/10; the top-rated is Villa avec piscine, spa et hammam (4.97/5).
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.

These places were suggested to us directly by their owners. The heated pool is declared by them; they don't yet have enough guest reviews to join the selection.
In my selection, the top-rated is Villa avec piscine, spa et hammam (Villa for rent · Airbnb), with 4.97/5 (100 reviews · Airbnb). Next come Appartement contemporain avec piscine (4.96/5) and Ondine Cottage (4.95/5).
None of the places selected on the Gulf of Morbihan clearly advertises a pool heated all year round. At Villa avec piscine, spa et hammam, Villa Alba and Grande longère rénovée (15 personnes), heating is seasonal (1 march to 11 november). Appartement contemporain avec piscine, Ondine Cottage and Ti Braz (Gîtes Parenthèse Breizh) have an indoor pool, sheltered from the wind. Either way, ask for the heating dates before you book.
Advertised temperatures: 29 °C at Sofitel Quiberon Thalassa Sea & Spa. For the other places the temperature isn't published: ask the property.
Yes: Sofitel Quiberon Thalassa Sea & Spa, Mercure Quiberon Hotel & Spa and Hôtel & Spa Thalazur Carnac (Les Salines) also have a hot tub in addition to the heated pool. No confirmed heated pool, but a hot tub: Le Diana Hôtel & Spa, Hôtel & Spa Le Churchill and Cabane sur l'eau avec jacuzzi.
Yes, 14 villas and holiday homes are selected: Villa avec piscine, spa et hammam, Ondine Cottage and Ti Braz (Gîtes Parenthèse Breizh). Heating is sometimes charged extra: check the listing.
The word "heated" on a booking page isn't enough. Every place must have a rating of at least 8/10 (or 4/5) and carries one of these four levels.
Guests mention the heated water in their reviews, with the season when they say so.
A journalist or guide who stayed there describes the heated pool.
The hotel or the platform says so, but I haven't yet found a review that confirms it.
Heating isn't specified, but the water is sheltered from the wind and cold air. Ask for the temperature before you book.
I left these out because guests report water colder than advertised, or because no heating or indoor pool is mentioned.
