Quoting that same person's latter reply: "One of the things about commercial equipment is the lack of insulation. So there could be issues with the booster heater affecting the counters around it. The moisture that comes with a high temp machine are also an issue. Maintenance can be a problem if he doesn't have a softener. EDIT: probably the worst thing though, which is mentioned by someone else below, is that if a c…

I’ve been kicking around the idea of a proper commercial kitchen in the house I’m thinking of building in the next few years, and it seems like this is definitely the kind of stuff you need to plan the whole room around. That said, who doesn’t want a big gas griddle, serious fume hood exhaust, and a giant three door stainless fridge in their kitchen?! I’m so tired of smoke detectors going off when I try to cook a ste…

Yep you can do it. One problem is that they are noisy. You will want to hide the extractor fans in the ceiling if you vent up out the roof. Bear in mind that a newer house will be tightly sealed too so your stove/ vent will need it's own air intake as well. I mean you can open a window but I think code will require it to prevent backdraft. Basically the air intake opens when you turn the fan on. Most of your other gas equipment (gas water heater and a gas clothes dryer) will be direct vent though in new builds.

In my bathrooms, there's already a drain in the shower (the shower is recessed an inch) and in the centre of the main area. They don't clog. I don't know about you, but I don't tend to wash baked-on lasagne from myself in the shower as happens in a dishwasher. I think it would largely be dust and the like if it wasn't left to build up. I'm thinking these things would be designed for new-builds rather than retrofitted…

Yes, wife and one daughter have long hair. We've not had a clogged drain in 10ish years in this house.

I don't think the sprays required to keep tiles clean would be enough water to flood an inch-deep recessed floor.

Rotating pressure sprays mounted about 6-7' up that spray the shower walls and bathroom floor, aiming diagonally down. Water would quickly drain via floor drains. Besides the toilet, it really only needs to deal with a bit of dust that wouldn't be hard to dislodge if cleaned every few days. I don't think it would need to be so hot that it was an issue if you were caught inside - just like being on the lawns when spri…

The key is that the volume of the dishwasher is small, and in fact it has heating elements (plus insulation) to raise the water temp, so it can recirculate that hot water (mixed with soap). I can imagine a bathroom with a drain (mine in fact has a concrete floor and a drain, so I can mop the whole floor into it) but there's no way to recirculate (or heat) water sprayed all over it, so the waste of water and energy wo…

I think a pressurised spray done frequently enough (every few days) wouldn't need much water and certainly less than I use in a daily shower.

There is a whole sub-industry of plumbing that clears clogged drains. Suffice to say the risk should at least be considered.

I'm not thinking of something that sprays a high volume of water for a long period. More like 15-60 second spray down of a shower, for example. And then a second spray if there was a way to rinse/dry/whatever. Shouldn't be enough to flood a typical recessed shower floor, or a purposefully recessed bathroom floor.

I find that recent models of dishwashers don’t work nearly as well as older models. They don’t heat up enough to dry water off of plastic, and the enzyme based detergents don’t seem to clean as well as the old phosphate detergents. Also, the dishwasher in our current apartment (a cheap Whirlpool) often leaves a wet dog smell on the glasses, and we can’t figure out where it comes from or how to get rid of it. Apparent…

We had a bad fish smell on glasses; it was due to food particles trapped in the pump housing behind the screen filter. Disassembly and a hose-down of the screen, plus a vinegar load, fixed the issue.

I suspect the offending food particles will tend to always be somewhere near the heating element, aka bacterial incubator.

I wish they invented the dual side-by-side dishwasher. I want separate dirty and clean units. I’m tired of using the sink or shelves as a buffer. Just pull from the clean unit and push into the dirty unit and rotate which is which. Voilà, dramatically less handling.

Buy two slimline units. An ex colleague of mine did that years ago.

That's how I remodeled my bathroom. I opted against materials that require grout lines, among other things. It looks boring and utilitarian but its a hell of a lot easier to clean.

Giant fiberglass bathroom?

Or if you eat fresh foods.

Why is this being downvoted? A balanced plate may be easier to wash. Starch absorbs fat, some acidic liquid will keep the fat and starch from sticking too much. Get your plate to the dish washer, rinse, and without need none to little soap will get rid of all the residues. The fat is already stuck to other particles so won't need much soap. What's the point of teaching Chemistry if the kitchen always looks like a cum…

What on earth are you on about? How are you going to prepare a meal with fresh ingredients with that list?

There are widely known fresh ingredients containing fat, acidic liquid, or starch (e.g. avocados, tomatoes, sweet potatoes respectively, although tortilla would be a more conventional third example given the first two).

This list. Where are you going to cut your sweet potatoes? On a plate? How is this list of equipment sufficient to prepare and cook meals?
