However, if you have the right knowledge of what to look for when deciding on the unit to purchase, the process becomes much easier.
Here we discuss key factors to consider when looking for the best bathroom fixture. Besides, we also answer two crucial questions to enlighten you on how to choose a dual flush toilet that meets all your requirements.
The following are some of the factors that you need to put into consideration to ensure that you choose the right unit:
When it comes to dual flush toilets, there are two different styles to choose from, two-piece or one-piece style. The most toilet style of the two is the two-piece, which means that the tank and the bowl of the tank are separate pieces that are bolted together.
As mentioned earlier, two-pieces are mainly preferred by some users, as it is easier to find their parts and tend to be less expensive than one-piece toilets.
On the other hand, one-piece toilets are easier to install as compared to their counterparts. Moreover, one-piece offers a sleeker design and is less likely to trap bacteria as there no hidden spaces.
The other important factor to consider is the height of the toilet seat. Selecting a product with an ideal height offers much-needed comfort.
Besides, it also determines whether a suitable toilet for people with mobility issues and different sizes. Usually, most individuals prefer elongated toilets, as they are more comfortable than conventional toilets.
The dual flush toilet should have a great design that enhances the look, functionality, and performance. Choosing a toilet with a round-front bowl helps create enough space on the sides, making it ideal for bathrooms with limited space. Moreover, it is also good to pick a unit with a compact design, but without compromising on your comfort.
Studies have shown that toilets account for about one-third of the water used in most households in the U.S on average. Therefore, there is a great need to invest in a unit that works efficiently with little water.
The best product should be certified by WaterSense (EPA), which means that it should utilize 1.28 GPF or lesser than that amount of water.
Usually, the gravity-flush and the pressure-assisted systems are the most common flushing system in most toilets on the market.
