Do you drool over the rows of pretty little shampoo bottles in the housekeeping cart in the hotel hallway? You’re not alone. Recently, Hilton Hotels conducted a survey that found that 73% of travellers take home their shower amenities. Starwood Hotels marked a 30% increase in people pilfering moisturizer over the last 10 years.

Luxury hotels (and some budget-friendly ones too) are upping their powder room prowess, offering some of the best products money can buy, included in the price of your room. So, don’t feel guilty -- they want you to take these pricey potions home with you.

From Oscar de la Renta to Asprey of London, the world’s best fashion designers, perfumers and salon magnates are creating exclusive lines of bath products for hotels the world over. Here are the hotel bath products that are worth checking an extra bag for.

Peninsula Hotels

A classic designer for a classic hotel: This 100-year old hotel chain has teamed up with fashion powerhouse Oscar de La Renta to provide an exclusive line of soaps, shampoos and body lotions at all of their 5-star properties.

Fairmont Hotels

The New York based luxury fragrance line Le Labo curated a scent just for this hotel chain. Rose 31’s aromas fill the steamy bathrooms of Fairmont Hotels all over the world with their shampoos, conditioners, body washes and lotions, as well as soap bars.

Waldorf Astoria

Ultra-famous Italian shoe designer Salvatore Ferragamo left a dynasty behind (he invented the wedge heel), so it’s fitting this fashion house paired up with the equally exalted Waldorf Astoria Hotels. The Tuscan Soul scent combines citrus, floral and woody notes and includes a wide variety of bath products from lip balm to anti-aging face masks.

W Hotels

This New York City spa’s Canadian owner started out doing facials in her loft. A decade later, she has a line of products available at luxury retailers Saks Fifth Avenue, Harrods and now in the comfort of your hotel room. The Lemon+Sage line ranges from body butter to foaming face wash.

Ritz Carlton

Asprey’s luxury goods range from jewelry to polo equipment, and include their signature citrusy scent, Purple Water. These swanky suds retail for over $150 a set, making it totally worth your while to pack a couple in your carry-on after a stay at the Ritz.

Shangri-La

BVLGARI is the expert in all things lavish, so it is only fitting that their signature White Tea bath line appears in luxury hotels like the MGM Grand in Las Vegas and Le Meridian in New Delhi. The rare white tea used in these products only grows in remote areas of the Himalayas in Nepal, so no wonder a 200-mL bottle of BVLGARI shower gel goes for $62.00.

Westin Hotels

Molton Brown is a standard in 5-star bathrooms all over the globe. You can find their hotel line at the Emirates Towers, Westin Taipei, Only Ocean Club Bahamas, Hotel Cipriani, the Pierre, the Mandarin Oriental and the Meadowood Napa Valley. Their Gingerlily collection was inspired by Tahiti’s exotic and inviting atmosphere.

Le Boutique Hotel Bordeaux

Much like the Hermès Birkin Bag is their signature purse, Eau d’Orange Verte is this luxury brand's signature scent. The scent was derived from the inaugural Hermes cologne, known for its distinct freshness. If you too want to lather up with this authentically luxurious line, you can also visit the bathrooms of Alvear Palace Hotel and Sofitel Hotels.

Kimpton Hotels

Kimpton Hotels carry bath products from America’s oldest apothecary, C.O. Bigelow. Nothing says luxury quite like showering with top-notch bath products, and then relaxing in one of Kimpton’s signature leopard print robes. The robe might not fit in your suitcase, but the C.O. Bigelow soaps certainly will. Other hotels that carry these classic toiletries are Triton, the Chicago Athletic Association, Soho Grand NYC, Hotel Adagio and the Cosmopolitan of Las Vegas.

The Gramercy Park Hotel

Lucky for us, the Australian brand Aesop is now available in hotels just across the border in New York at Gramercy Park Hotel and Hotel Americano. The Geranium Leaf Body Cleanser is Aesop’s best-selling product, and all Aesop products are created by the company’s own team of chemical scientists, so you know that the products in your bathroom (and probably your suitcase) are top of the line.
