<p>Well thats creative The floor probably couldnt support it, though. When I was in college several students tried to install waterbeds. That was also a no-no.</p>
<p>Someone installed an honest to goodness hot tub on top of a roof of an academic building at umich a few weeks ago. I didn’t search for any follow up articles but the one I read said that they’d had no idea who did it and that it disappeared as mysteriously as it had appeared the next day. Apparently it was a big deal, apart from the obvious, because nobody had any idea how they fit it through the door to begin with.</p>
<p>Never underestimate the ingenuity of college students. At my college we would take the sliding wooden doors off the closets, put them in the shower and plug up the drains to make a mini pool.</p>
<p>My structural engineering professor told us that MIT students blocked the drain of one of the buildings with a concave roof (who thought that was a good idea?) and made the entire roof a swimming pool. Luckily he had over-engineered the roof to accommodate just such a hack.</p>
<p>^ I would think the engineering would have taken into account the drain becoming (accidentally) plugged and figured in the weight of the water. Now as to the weight of the swimmers… </p>
<p>It’s not as a cool of a story as it sounds. The hot-tub was placed on a large 4th floor balcony. The people involved in installing it included two faculty members who had access to maintenance/freight elevators, etc…</p>
