The Colosseum, Sydney Opera House, Central Park and reefs along under the Persian Sea are among the views guests can take in from their hotel bathtub.
With acres of marble framing postcard-worthy vistas, here are 10 views that make us never want to leave the bathroom.
Travelzoo Tip: The line for these bathrooms can run long -- that underwater suite for instance books up far in advance. Don't worry if you can't find these exact rooms, as these hotels excel on all sides: no matter where you book in the building, you'll get great design, top service and a prime location.
You'll shrivel up to a prune in this bathtub, trying (and failing) to peel yourself away from that view of the Opera House.
Anyone can be the fairest of them all when the mirror is crowned by this stunning panorama.
They've proven that shampoo and conditioner are more effective when applied against a backdrop of Central Park in a double-wide shower.
Don't be bashful bathing in front of the sharks that swim around this underwater suite -- they're not wearing any clothes either.
Sure, you could go across the street to the crowded beach, or you could stay in this quiet, private bathroom, where you don't have to share the sun and sea views with anyone.
You book an oceanfront suite because you never want to stop looking at the ocean, even while bathing. You don't have to worry here, where they plunk the tub right in the middle of the room.
At press time, traffic on Toronto's University Avenue (pictured) was verging on code red. That means lots of people sitting in stopped cars looking up at this hotel's glistening glass skin, into the sleek marble bathrooms within. Look good and don't be shy.
We could stay in here from sunrise to sunset. There's enough space next to the tub to fit a room service trolley, so don't judge.
You'd need to capsize a cargo ship full of bubble bath to foam up Shanghai's Huangpu River. Best to just stay in your room and stick to smaller-scale suds.
Repeat that lather-and-rinse all day if you must -- there's no rushing out of the shower when your next-door neighbour is the Colosseum. (See it peeking in there?)
