Things To Consider Before Buying The Aquia IV

Size & Shape:

When it is time to buy a toilet, you must be careful about the size and shape. There are different sizes of sizes & shapes. All of them provide comfort, but you have to choose which is an exact match for you. 

We recommend a medium size toilet because it provides comfort for all ages people. If you specifically need a toilet for your own, then talk with a professional who can suggest the perfect toilet according to your demand.


Material is essential because proper cleaning depends on it. Must try to choose the ceramic material because it looks good, lasts for long and cleaning is easy. As it’s too much slippery so, dirt can be washed easily by only one flush.


Color does not represent quality. It depends on your choice. 

There is some color available for this toilet. Our suggestion is to select the color matching with another piece of equipment in your washroom, and it will look beautiful.

Installation Process:

This one is an important thing, always choose simple toilets because complex design toilets need lots of time to install, and it is also sometimes tricky to fit correctly.

Flushing System:

Toilets need to be appropriately clean always. A proper and effective cleaning depends on its flushing system. A weak flushing system uses lots of water to clean the toilet. 

A better flushing system consumes less water and provides a powerful water flow that properly cleans the whole toilet.
