Yes, I have the LG it’s one attached unit
It’s really great! And we got it in red. The color is seen small from website but the actual description and name can be looked up for additional colors. (We got ours from Costco)

1. What are the dimensions of the available space?
2. Is there a 240 volt outlet for an electric dryer?
3. Is there a vent to the outdoors?

I also have a Washtower by LG, and it's a really good unit. No complaints; I've only had it about 2 years (but I've had other LG washers that have lasted a dozen years). It's 27" wide.....if you need a 24" wide unit, I still recommend LG.

Miele. Pick your model. They are all great. Dryers are ventless and run on 120V so you can put them anywhere you have a water hookup and a drain, like a bathroom.

My mom has a Miele and she really likes it. I don't know the models offhand, though, and she's two states away!
