Depends, if it's a bigger house, and it's in a properly isolated room that has it's own vapor barrier and is overall well built, and that there is still lot of basement left for a rec room and server room, and storage, then maybe. But if it's a standard size house and this thing is taking up precious basement space that could be used for something else, then no. It's one of those things where if it's there I'd probably use it, but I would not go out of my way to get one.
Indoor pools in a house are generally a bad idea unless it's well designed by someone that knows what they're doing, so there arn't mold issues. Seeing stuff on shows like Holmes on Homes done by "contractors" makes me think most people would not install an indoor pool properly.
If I was rich and had money to burn, I'd probably make a "pool room" just because. Something like what you see at hotels, it's properly sealed off from the rest of the building, has good ventilation etc. And a water slide! You have to have a water slide.
Can always do it outside too, but then it's a skating rink that turns into a pool for 2 months.
