Corrected entry: Just after Wesley's first training with the Butcher, he's in the healing room. His left hand had been punctured by the knife, so it makes absolutely zero sense that his hand is not submerged along with the rest of his body.

Correction: The liquid in the healing room is not explained, nor does it need to be. As a result, the audience doesn't know what properties are involved with healing in the healing room. It's possible that just breathing vapors, or osmosis through skin while in the room can have a healing effect.
