At the foot of Mont Blanc, Chamonix is a mountain town that's lively all year round, with the Aiguille du Midi and the Mer de Glace a cable car ride away. Climbers, skiers and hikers often come back exhausted: an indoor pool or a heated outdoor pool facing the glaciers is part of the pleasure. The selection covers the centre, Argentière, Les Bossons and Le Lavancher. I've selected 15 places, all rated at least 8/10; the top-rated is Chalet Hôtel Le Prieuré & Spa (8.8/10).
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 don't have a confirmed heated pool, but they do have a hot tub: the water is hot all year round. A good way to relax in the warm.
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 Chalet Hôtel Le Prieuré & Spa (Hotel), with 8.8/10 (712 reviews · Expedia). Next come Hôtel Mont-Blanc Chamonix (9.8/10) and Le Refuge des Aiglons (8.8/10).
None of the places selected in Chamonix clearly advertises a pool heated all year round. Chalet Hôtel Le Prieuré & Spa, Big Sky Hotel & Spa and Le Hameau Albert 1er have an indoor pool, sheltered from the wind. Either way, ask for the heating dates before you book.
None of the places selected in Chamonix gives a precise temperature. Ask the property before booking, especially out of season.
Yes: Chalet Hôtel Le Prieuré & Spa, Hôtel Mont-Blanc Chamonix and Le Refuge des Aiglons also have a hot tub in addition to the heated pool.
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.
