Patrick Bateman’s bathroom cabinet is one of the best ever featured in the history of cinema. He’s a psychotic narcissist who spends a great deal of time and money to take care of his physical appearance. No wonder that the selection of perfumes and hair, skin and body products in his bathroom is very refined and luxurious.
On the middle shelf of his cabinet we can see the fragrances Caron Eaux de Caron Pure and Yves Saint Laurent Pour Homme. The other products are L’Occitane Spray Coiffant (now discontinued), Phytoplage sun protection oil (old packaging) and Phyto Men Eau Vigoureuse body splash (now discontinued). The white jar – by L’Occitane – presumably contains a face cream or a mask.
On the bottom shelf there are three Phyto Men products and another fragrance – Pour un Homme by Caron.
On the top shelf there are two deodorants – Oscar de la Renta Pour Lui and Yves Saint Laurent Pour Homme. A bottle of Pour Lui eau de toilette can be seen on the far left side by of the screencap above.
We are also given access to Patrick’s shower, so we can see he uses Yves Saint Laurent Pour Homme all-over shower gel and L’Occitane Eau de Contadour body and hair shower gel.
More L’Occitane products are in the shower: there’s a bottle of milk shower cream (old packaging) and two shampoos – Shampooing Eclat and Shampooing Nourissant (now discontinued).
On the bathtub metal tray there’s a bottle of Antica Erboristeria 
From a different perspective we see there are other two shampoo bottles on the tray – Johnson’s Baby 
On the table by the door there’s a bottle of Roberts Borotalco 
There are two cans of Barbasol shaving cream in Richard Chance’s bathroom cabinet.
There’s a can of Barbasol Soothing Aloe shaving cream in Joe’s shower.
There are several toiletries in Dodd’s bathroom, among which a can of Gillette shaving foam and a bottle of Pepto-Bismol.
The bottle right behind the Pepto-Bismol one contains Resdan
