How would you design/build a bathroom to be able to clean it with pressure washers?

I guess this is far more complicated: how would you build a sewerage system for bathrooms and kitchens that can clean and reuse a percentage of the (mostly clean or soapy) water? Is something like that even possible with current technology?

Its called a wet room

Nice, I didn't know that was a thing. Thanks anon.
I guess this thread is kind of useless now. I can't delete it though.

It takes careful design from the ground up.
You start with LVL OSB beams for the floor joists, then layers of OSB for the sub floor.
Next you want to use another layer of osb coated in epoxy on one side and set your tile work on that. Make sure to use the cheapest caulk because it will be fine

build it out of concrete

It's called grey water recycling
There's a ton of methods and a bit of a rabbit hole

encapsulate it one piece made of abs plastic like they do in many apartments in Japan or in cruise ships.

I did this. I didn't even need to use wax rings on the toilets.

Only retards go to that thread, retard

I'm a tourist and I don't know this board that well. I did look for the sqt but I only glanced over the first few threads and it wasn't there.

tile anon is gonna have a stroke

You should use epoxy grout, a pressure washer would probably erode sand grout.

I see you too build modern homes. It's nice to meet another man of class.
