A former imperial resort, Biarritz stretches between the Grande Plage, the Rocher de la Vierge and the Côte des Basques, with Anglet, Bidart and Saint-Jean-de-Luz as neighbours. On this Atlantic coast, the weather changes quickly and the ocean stays cool for much of the year. Several hotels have a thalassotherapy centre with a heated seawater pool. The selection mixes a palace hotel, thalasso hotels and villas inland. I've selected 11 places, all rated at least 8/10; the top-rated is Villa lumineuse, piscine chauffée près de Biarritz (4.98/5).
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.

In my selection, the top-rated is Villa lumineuse, piscine chauffée près de Biarritz (Villa for rent · Airbnb), with 4.98/5 (44 reviews · Airbnb). Next come Villa en bois vue mer, piscine chauffée (4.92/5) and Hôtel Maison Chiberta (8.9/10).
None of the places selected in Biarritz and on the Basque coast clearly advertises a pool heated all year round. At Novotel Resort & Spa Biarritz Anglet and Le Talaia Hotel & Spa, MGallery, heating is seasonal (april to october). Hôtel Maison Chiberta, Grand Hôtel Thalasso & Spa and Madison Saint-Jean-de-Luz have an indoor pool, sheltered from the wind. Either way, ask for the heating dates before you book.
None of the places selected in Biarritz and on the Basque coast gives a precise temperature. Ask the property before booking, especially out of season.
Yes: Grand Hôtel Thalasso & Spa, Madison Saint-Jean-de-Luz and Hôtel du Palais also have a hot tub in addition to the heated pool. No confirmed heated pool, but a hot tub: Thalazur Saint-Jean-de-Luz and Villa sur le golf avec piscine et spa.

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.
