Nestled within a Grade II-listed chalet on the banks of the Thames, this bathroom is a masterclass in opulent excess. Located in Macau, China, The 13 hotel is obscenely high-end with absolutely zero expense spared on the bathrooms. This master ensuite takes your breath away with a stained glass rain shower, freestanding marble tub and gilded candelabras. Guests who are wealthy enough to afford a night or more in the sumptuous Affresco Suite at Florence's Hotel Il Salviatino , a converted Renaissance palazzo, can gaze up at beautiful ceiling frescos while they relax in the bathroom's magnificent ancient stone tub. Soaking in this whirlpool tub surrounded by colourful tropical fish has got to be heaven. The Honeymoon Suite at the high-end Madikwe Hills Private Game Lodge is blessed with the most incredible space: an outdoor terrace bathroom where guests can watch elephants, lions and other big-game animals roam as they sip champagne in the tub.
