No, our old basement laundry sink had one built into one side of it but our “new improved” one doesn’t. I should probably pick one up. In a pinch, I could use a 5-gallon bucket with a gamma seal and agitate it manually.

I love the sound of that old sink!

I've got loose plans in my head to make a cycle washing machine when I get settled off-grid, I've never seen one before, but it strikes me a no-brainer - a washing machine drum, connected to a bike with manually controlled water inlets/ outlets - it'd be a bit of a mission, but very achievable, and a spin work-out too.

There are small hand-cranked ones commercially available:

Haven’t looked, but I’d be surprised if there weren’t bike-powered designs on the web.

I couldn't imagine hand cranking a wash - cycling seems so much easier, it must be a thing already!
