What to Consider When Choosing the Best Dual-Flush Toilet

1. Water Conservation

The idea of getting the best dual flush toilets is to save water in your home or workplace. Thus, getting a toilet that saves one’s water is always recommended. From the above analysis it is clear that various models require varying amounts of water. For instance, the fourth strategy in the list above saves water while the other four strategies do it in better ways.

So if you want the least water to be used, you can look at how many gallons are used per flush. Moreover, the usage of dual flush makes the usage of water far much less than that used in the traditional single flush toilet.

2. Toilet Type

There are different types of toilets, including one-piece toilets, two-piece toilets, and wall-hung toilets. The first option is preferred most of the time because it requires very little assembly. Indeed, what you will come to realize from this design is that the tank and the bowl are actually one and the same. This results in a one-piece toilet with a modern look that is very easy to maintain. Furthermore, in the one-piece toilet case, you may not worry of bacterial buildup on this toilet you are using.

Cleaning and maintaining the two-piece toilet is easier and it’s best suited for the more conventional bathrooms. But at times may need the services of a good plumber to guide assist in fixing this type of toilet so that there will be no future leaks. The bowl and tank are coupled to each other by a seal.

These types of toilets are affordable. The third type of toilet is mounted to a wall. This wall mounted toilet is gaining more acceptance, particularly to those clients who have a small baths and want to create some space. This one below you can get for your downstairs bathroom.

3. Shape and Size

When choosing the best dual flush toilets, it depends on the size and the shape of the toilet to fit your space. On this we get two shapes, the round bowled and the elongated bowls. What you will find out is that the round bowl is chunkier and has shorter height than the elongated bowl.

The elongated dual flush toilet is about 2 inches longer than the round toilet and has its length varying between 18-19 inches. The elongated bowls make the toilet easier to sit on as compared to other toilets especially to the male person.

It therefore does not matter whether you own a Kohler K 3987 0 or any other toilet that utilizes the dual tornado flush system, the comfort of the seat follows a different statement. That extra inches at the front research can do a lot.

4. Technological Innovations

Modern toilets come with cool features that improve your bathroom experience. For example, many modern toilets use a pressure-assisted flush system that uses air to suck the water and the waste from the bowl when it comes to the flushing system.

Old models have a gravity flush structure that cannot compare to the Dynamax tornado flush system or any other dual-max flushing system.

Although modern systems are more expensive, they are with them because they are more efficient and leave your toilet extremely clean.

Conclusion

Of all the best dual flush toilets above, which one did you find most appealing? In the process of grappling into a new dawn of a cleaner environment there is need to factor water conservation and having a dual flush toilet must be a way forward towards saving a lot of water.
