I was apartment hunting this year, and one apartment I visited had a Jacuzzi as one of its selling points. It turns out it was just a Jacuzzi-branded bathtub. In the corner of the bedroom. Surrounded by carpet.
I didn't think to take pictures, and the posting is long gone. I assume someone was desperate enough for an apartment that they were willing to pay for that crummy place.
Wait that's a hot tub? Holy cow, did the designers of this house never stand within 5 feet of a hot tub before? The air around a hot tub is always very humid and smells like chemicals. Plus there's always some noise even when the jets are off. Who on earth would want to put that in the middle of their main living area?!
I think this one is meant to be just a large bathtub, so no smell of chemicals/noise and potentially just for one person or two depending on size, plus you can have a bath while waiting for your roast
