Everyone likes a trip to the spa, but it seems the whole process would be that much more pleasant if you could soak, steam, and luxuriate without ever leaving your building. And if you're willing (and able) to shell out huge amounts of money, plenty of towers in NYC have spa amenities that'll let you do just that. Forget the in-building gym: we just want a sauna.

Besides a pretty major view of the Statue of Liberty (seriously, you could supplement your income by charging for tickets), residence in this $4.1 million Battery Park City three-bedroom also includes access to Jacuzzi spa treatment, as well as an on-site sauna, steam room, and swimming pool.

If you rent one of the sleek condos at the W Residences in the Financial District—this one-bedroom is on the market for just over $1.3 million—you can take advantage of the building's "hotel-style" amenities, which include sauna and spa facilities, plus room service once you've sweated out all your toxins.

Apartments at One57 in Midtown come with many, many bells and whistles—and for this three-bedroom rental, a $55,000 a month price tag—not the least of which is access to the Park Hyatt Hotel's indoor pool, steam rooms, custom Jacuzzi, and "spa portico."

For $6,500 a month, you can net the penthouse of Trump Place at 120 Riverside Boulevard, an amenity-laden building with a spa that includes a Jacuzzi, steam room, sauna, massage rooms, and a pool.
