I used to visit the nearby Yamada-yu (which closed about a year ago), and on its closing days, I'd explore various other sento, always impressed by their distinctiveness.
I heard that Kyoto sento lack the iconic painted Mount Fuji murals common in Tokyo. Instead, the painted areas are tiled, often featuring tile art. Some sento are said to have Fuji depicted in tile.

The sento I know with a "tiled Mount Fuji" is Funaoka Onsen. Visiting this bathhouse moved me deeply. Funaoka Onsen is, quite simply, astonishing.
The building is a Tangible Cultural Property registered by the Agency for Cultural Affairs, its exterior so grand it could be mistaken for a Kabuki theater. Inside, the elaborate interior is even more surprising.

Look up at the ceiling. It's vermilion. A carving of a tengu immediately catches the eye. On closer inspection, it's Yoshitsune and Kurama Tengu, with a young tengu as well.
Furthermore, the transom surrounding the changing room features openwork carvings depicting scenes of war, which I recall reading in the Kyoto Shimbun were inspired by the Shanghai Incident. Despite being a changing room, it exudes an unexpectedly refined atmosphere.
As a side note, the day after reading that newspaper article, I visited Funaoka Onsen for the first time.
