A 'yù tǎn' (bath blanket) is a large, absorbent, soft textile used after bathing or showering—similar to a towel but thicker, warmer, and often quilted or fleece-lined. The character 浴 means 'bath' or 'bathing', and 毯 means 'blanket' or 'rug'; together they literally denote a blanket specifically designed for post-bath use. Unlike regular towels, bath blankets prioritize warmth and comfort over quick drying, making them especially popular in colder climates or for children, elderly users, or spa settings.

This item is commonly found in homes, hotels, and wellness centers across China and other Chinese-speaking regions. It's typically hung near the bathroom or laid out on a heated floor before stepping out of the shower. While functionally overlapping with bath towels, the bath blanket emphasizes thermal retention and gentle skin contact, reflecting cultural attention to post-bath body care and comfort.
