Most people
go for toilet paper caddies 
nowadays rather than hard wiring it. The main advantage is that you don’t have to touch the walls to get the tissue, which is more hygienic. But choosing the right caddy for you is a simple task, if you give attention to the details, else you end up bringing the wrong one which then becomes the greatest flaw of your bathroom. So how do you choose the right one? I had the same question, while I thought of purchasing one.
Well, the toilet caddies come in three different finishes: chrome for modern bathrooms, golden-hued satin nickel for classic bathrooms, and oil-rubbed bronze for European continental bathrooms.
These are just the basics, nowadays you can find different varieties of these in the market. So, have an idea in your mind, how you want to pair the caddy with your bathroom. Then try to select. Also, think of the different features the toilet caddies have. The most common feature is a toilet paper dispenser. However, even that is optional! If you already have a dispenser but just want a stylish place to store your additional rolls of toilet paper, then you can select the caddy accordingly.
