As the floor-mounted one is supposedly more secure and can hold more weight. On the other hand, a wall-mounted toilet will take up less space and makes cleaning the floor easier.

Adjustable Height:

Just like the size of a toilet, the height also varies. For single people having one height toilet is fine. But a family with members of different ages might not feel comfortable with one size.

A toilet does not have a wide range of waste temperature adjustments. But, any product with 4 to 5 adjustments will suit most of the users. Just check what these adjustment temperatures are and if you are comfortable with them.

Dryer & Heater:

Most people prefer having a dryer in their toilet seat for obvious reasons. But having a dryer is not enough. The built-in drying feature should be adjustable. A toilet with at least 2 different drying levels would work great. A heater feature is a bonus for those living in cold cities. As people like using the dryer in summer and heater in winter.

Automatic Toilet Lid:

Whether the toilet is tankless or not, the automatic lid is popular nowadays. What does an automatic toilet lid do? Nothing fancy. To make it simple, a toilet with an automatic lid has a sensor.

But if you want to just install a toilet and forget about it then lubricated one is the best for you. So what this feature does? Well, it creates a moist layer on the inside. This lubrication makes cleaning easier.

Built-in Deodorizer:

There are few ways to make a toilet smell great. Some people use air spray while other wash towels with fragrant soap in the hope that it will enhance the overall smell of the toilet. You can also use perfumed pockets. But if you are lazy, just get a toilet with a built-in deodorizer. This feature prevents bad odor and makes the toilet smell fresh. You will also save a lot of money on scented toilet products.

Smart Wand:

Some toilets have built-in sprayers while others have a wand and some have both. While one is not better than the other but if the toilet has a wand it should be a smart one. Why is that important? Users can change the direction of a smart wand using the remote. Some wands even have a self-cleaning feature that creates a bacteria-free environment.

Remote Controller:
