Yes.

It is not anything new, one ambient light (Uber or AOA), a couple of key lights depending on the scene (infinite or spot) and a lot of fine tuning but it also requires a lot of knowledge in shading and texture to make it match, and for that I have at least 10 different 3Delight compatible surface shaders I mix here and a hell of other tweaks.

For the settings you must take a look online and find what works best for you, it is a bit impossible to cover light as a tutor with the amount of work have now, also talking about surfaces (shader/texture) is a whole other thing, so, I could give you a tip or two when you get stuck but I really recommend building your knowledge online first, there are a lot of info available at Daz Forums and on the internet.

Considering the unified universe, there's a "domina sized", most common in Domina's Valley, of course, where stuff comes in sizes about 50% bigger than normal, so, you would get appliances and other things in a bigger size, this covers most stuff in their life.

It is also common pairs of toilets with different sizes.

Otherwise, stuff is custom made, and if you're a giantess, or you know people who makes customs, like Tony does, or you're rich. Or you live in Domina's Valley where a big part of the population is bigger than average...

Vanessa cup size can't be measured in normal standards, to be honest I ain't aware of most of the cup sizes there... gotta fina a way to measure them.

As for Tony, well, I'm not exactly too curious about that, but he might have about 20 inches of dick. Dude, that's a lot...
