We have an 18 year old daughter living at home still, my husband, baby son and I.
Our shower is a bit of a nightmare, and we only have 1! (This house is too small for us, Luckily the shower is large!)
I have a 3 tier shelf that hangs off the shower spigot and one of those 4 tiered shelves that goes from the tub to the ceiling. And it's loaded, I probably should get rid of it, because I absolutely hate it and swear at it every 3 or 4 days when I clean it!!
On the shelves there are 3 bottles of conditioner, one deep conditioner for dry hair, and 2 different types fruity scented ones, 1 bottle of apple cider vinegar, (I like to do a vinegar rinse a few times a week) 5 bottles of shampoo, One for dandruff, one for psoriasis, one baby shampoo and two fruity scented types.
One bottle of pomegranate scented body wash, 2 bars of homemade bar soap, one oatmeal and goat's milk (baby's skin) and one magnolia scented, 1 bar of Coast deodorant soap.
On the shelving unit that hangs from the shower, there are 3 types of facial cleansers, 2 buff puffs, 2 razors, one shower mirror, and one shower radio.
(waterproof radio) A loofah, And a back brush.
