About Tokumitsu Taanto Interior de lavabo públic

Tokumitsu Taanto és un interior de lavabo públic situat a Hakusan, Ishikawa, Japó. La sala ocupa 25 metres quadrats i té una alçada de sostre de 2,90 metres. Més de 3.000 rajoles de pa d'or cobreixen les parets. Cada rajola és una peça de porcellana quadrada de 200 mil·límetres amb superfície texturada, acabada amb pa d'or de Kanazawa aplicat a mà. Les rajoles es disposen sobre un fons fosc, i la il·luminació indirecta està organitzada per revelar la qualitat reflectant de l'or. El disseny aplica una artesania tradicional japonesa a un espai públic contemporani.
