Washington State Directory Lists 278 Bitcoin-Accepting Merchants

Bitcoin-accepting merchants — A new community-maintained directory lists 278 businesses across Washington state that now accept Bitcoin, including a hot tub manufacturer that uses mining rigs to heat its water.

The list, compiled via the BTC Map survey, spans 94 cities, with Seattle leading at 46 listed merchants. The businesses range from coffee shops and restaurants to salons and specialty retailers, highlighting growing local adoption.

One standout merchant is Snorkel, a hot tub maker that began accepting Bitcoin in 2025 after a bet by owner Michael Diederich. The company has since developed a prototype tub heated by two Bitcoin miners, which can raise the water temperature to 104°F in under four hours.

Diederich, working with Hashrate House, envisions a future where mining income offsets the energy cost of heating electric tubs. The project recently won an innovation award at the Heat Punk Summit in Denver.
