Floor sloped to middle, floor drain, and marble, granite, or some other kind of waterproof tile and grout on the floor, up the walls, and even on the ceiling. Plumb a steel line through the walls to a quick connect to plug in your pressure washer outside and run it inside to wash it all down.

Or stainless sheeted and fully welded seams.

>self cleaning toilet
i'd probably not design it like this

>>2977903
The biggest issue with toilets is piss, it splashes even if just a little, dries and starts to smell over time. If you had a toilet for shitting and a urinal for pissing you'd need very little maintenance.

>>2977914
What about other parts of the bathroom, like the shower? Soap scum builds up over time

Oh man, those 1950s style bathroom-of-the-future UV disinfecting lights that briefly came back during COVID have always intrigued me, but they sound like a pain in the ass in practice

Build the bathroom out of non-porous materials and cleaning it will be a breeze

>>2977937
They only disinfect, they don't clean.

Just build out of non-porous materials, SS steel, glazed tile (grouted with Opus signinum or other GP mortar), granite etc

The annoying parts of cleaning are cracks crevices and porous surfaces

Every surface is one solid slab of marble. Apply a peelable clear film on each surface. Once a week peel off old film and apply new one.

Any tips to make my flat easier to clean generally? I spent a few days fixing my cable management, that helped but ideally I would like most things to take as little time as possible. I already have a robot vacuum and mop.

>>2978537
Have less stuff. Put stuff in closed storage spaces so less dusting is needed. Make it easy to move furniture around so you can clean underneath/behind. Always consider how much effort is needed to clean something if you want to buy something new. Have the right cleaning agent for each job. Have someone else do the cleaning.

>>2977923
if you dont have hard water, soap scum isnt as bad...probably should be filtering any water you put on your body anwyay and then reusing it for non vegetable irrigation

>>2977903
It takes 15 minutes a week to keep a bathroom clean. If you spray the bowl, just clean it right after flushing instead of letting it sit for weeks. Keeping things clean is easier than cleaning.

>>2977923
I just keep a small squeegee in the bathroom, once a week I use it right after I finish taking my shower, takes a minute.

>>2977903
Toilets used to be self cleaning before they put in all this water rationing bullshit. The turds would also make it all the way to the street.

I'll give it to you straight: we've been trying to work this out for the past 40 years. There still isn't a good solution. The in-tank chemicals are some of the closest that there is when it comes to extending time to between cleaning, but ultimately there is no replacement for physical displacement. Eventually, the chemicals will run out, bacteria will build resistance to chemical attacks enough to grow where concentrations are lower, and once the bacteria establishes a layer of biofilm on the surface it's just a matter of time for it to spread. The biofilm creates a protective layer where the bacteria underneath can continue to spread. Even if you kill the surface, the carcasses of the film still create a layer protecting the bacteria underneath, so higher chemical concentrations aren't the solution here. Different chemicals can remove this film but are also so incredibly bad for the environment that you would be fined for flushing them down the drain should the authorities find out.

Next, consider where the filth is. Hydrophobic surface coatings can help reduce skid marks and the like underneath the water, but anything that dries above the water line becomes difficult to remove. Splashing piss will never have a good solution with conventional bowl shapes and flushing methods (spoiler: those are also unlikely to change anytime soon due to codes and standards regulating them). Hard water will also negatively impact cleanliness. Do NOT use pumice to remove hard water stains; this will damage the enamel and lead to faster bacteria buildup since you create thousands of little cracks that bacteria can hide in. Turn supply stop off, flush, then use chemicals to dissolve away the hard water. And sit down to piss, you'll get less splashing, extending time between cleaning.

Also if you don't have a bidet why are you worried about your toilet when you're walking around with shit smeared all over your ass.

They bleach the shit out of everything according to what I've read, which is the pain in the ass part. But yeah, they won't wipe up for you.

>>2980126
I hate the laws so much. Fucking retards are just like 'those old guys were just being wasteful we can use less water with modern science!!'


No now it just sucks

>>2977903
I used to work as a butcher in a factory and the entire workplace was washed using a pressure washer. Everything mechanical was waterproof, there were drains in the floor every couple meters and the walls were covered in some vinyl sheeting. The pressure water would first shoot a foaming detergent/sanitizer that we'd have to leave for 10 mins or so, and then we'd rinse everything down with hot water, use a big squeegee broom to push water to the drains and the ventilation system would get rid of any residual humidity.

I've always fantasized about implementing something similar for a kitchen or bathroom. Just a minimalistic space with stainless steel or porcelain furniture that you could just blast with a pressure washer to sanitize and clean.

>>2980226
it's been like this in basically every factory i've ever worked, drains sprinkled everywhere, pressure wash the walls / ceiling.

>>2977903

Bump for more ideas

OP- There used to be a style of combination unit (sink and commode) that was used on railway cars, for the roomettes/suites. It was made of stainless and would fold into the wall.
If you improved on that, so that when folded it initiated a wash function similar to what is used in a dishwasher, you'd probably achieve what you're after.
Here's a pic of a modern, similar stand alone folding sink.

>>2977905
All of this but instead of a pressure washer use steam jets to clean everything.

>>2977905
op should just make a giant dishwasher and he can just climb in the fork basket and get sprayed in the face for an hour. also it can have garbage disposal in the drain for poop

Plastic floor and walls, centrally placed showerhead with a bidet nozzle that reaches everywhere. No small hidden corners.

Every time i shower i hose down the whole bathroom and scrape the water into the drain. Sometimes i hit everything with chlorine foam.

It is so great you cannot believe.

>>2985417
Used to hit it with the power washer, but it really isnt neccesary.

>>2977903
just clean your fucking bathroom.

OP here. Tbh I was asking about both toilets and whole bathrooms in general.

>Hydrophobic surface coatings can help reduce skid marks and the like underneath the water, but anything that dries above the water line becomes difficult to remove.
so hydrophobic materials don't work on fecal matter? above water?

>>2980226
that's kinda what I was thinking of. waterproof/metals/plastic materials, drains, and powerful fans + good, well thought out ventilation.

>>2986341
kek. I can imagine that.

You guys are overcomplicating the fuck out of this problem .

Asians figured this out centuries ago. You don't need space age materials or automatic cleaning cycles. You just make a bathroom out of concrete or tile (Japs use plastic) and put a drain in the floor. When you take a shower you can spray down everything in the bathroom, the toilet and sink etc. There you go. Self cleaning.

>>2977937
The light that comes off them is much more damaging and cancer causing than your wild-harvested uvc. It also makes ozone which kills everything and gives hella cancer as well.

For the past six months I've had a Toto washlet with pre & post mist, using what they call EWATER+. Pic is how they describe it.

Premist is good because it means any poop that touches the porcelain above the water line is less likely to stick/more likely to get washed down by the flushing action.

Postmist is good because it's kind of spraying down the bowl with a weak bleach solution. It uses the same stuff for the nozzle self-cleaning routine.

I still clean the bowl with a brush as part of my bathroom cleaning routine, but it pretty well stays clean on its own.

>>2977937
They're worth it IMHO

>>2980069
Wat

>>2992426
Toilets used to flush with like 2.5 gallons and your shit would actually make it all the way to the street and the bowl wpuld get almost entirely cleaned out. California and NY mandated 1.1 gal max and they're such huge markets manufacturers just limited all their toilets to it. They literally don't make them like they used to

I have a water gun in my toilet, so I can blast the shit stains on the toilet bowl with it. I ain't scrubbing that shit.
