A Buyer’s Guide to The Best Toilet With Powerful Flush
There is a surge in the number of toilets with a powerful flush in the market, which makes choosing the best one overwhelming. For this reason, you should consider these factors to choose the best toilet with powerful flush.
1. Flushing Toilet Type
Flushing toilets come in different styles and types, so you should choose one that suits your home depending on your taste and preference. The different flushing toilet types include;
a) One-piece Toilet
This toilet type integrates the toilet and bowl as one unit. As they are a single unit, one-piece toilets are easy to install and clean. They are common in modern, contemporary, and eclectic bathrooms, thanks to their sleek appearance.
b) Two-piece Toilet
As their make suggests, two-piece flushing toilets come as two units, the bowl and the tank bolted at the top.
c) Tankless Flushing Toilet
This flushing toilet lacks a tank, so it connects directly to the water supply line. Thanks to the lack of a tank, these toilets take less space, so they are ideal for both small and large bathrooms.
The tankless unit is among the quickest and strongest flushing toilet as it connects directly to the water supply line, unlike other flushing toilets that depend on tanks. A tankless toilet can suit a modern, contemporary or eclectic home.
d) Wall-mounted Flushing Toilets
These toilets are bolted to the wall; therefore, they do not take up much floor space. Wall-mounted toilets, also known as wall hung toilets are ideal for both small and large bathrooms. You can further install this type of toilet in an eclectic, modern or contemporary interior.
If you or a family member has limited mobility, this type of toilet is suitable for your home as it makes transferring fom a walker or wheelchair easy. That said, ensure that your house’s walls are thick enough to support the unit before selecting this toilet type.
2. The Toilet Size
You want to ensure that the flushing toilets fit properly into your bathroom space; therefore, you should consider the size before purchasing. You should consider the distance between the floor drain and wall when determining the best flushing toilet size. The standard toilet measures 12 inches, but you can still find a larger one measuring between 10 and 14 inches.
Additionally, consider the height of the toilet. An ideal flushing toilet height should guarantee maximum comfort, especially if you or a family member has limited mobility. A more comfortable toilet height measures 17 inches, while the standard flushing toilet is 15 inches tall.
3. The Toilet Bowl Shape
When choosing the best toilet with powerful flush, the shape of the bowl or seat is of paramount importance. This is because it contributes to your comfort while using the flushing toilet. Now toilet bowls come in different shapes, including;
a) Elongated Bowl Shape
These are toilets with a larger rough-in measurement and is a few inches deep to provide comfort while using the toilet. The large rough-in measurements on the elongated flushing bowl toilet provide accommodation for its increased depth.
The elongated bowl is the most common best flushing toilet and is available in various styles, including one-piece toilet, two-piece toilet and wall-mounted toilets.
b) Round Toilet Bowl Shape
As their name suggests, round toilet bowl shapes have circular rims with short rough-in measurements and are ideal for small bathrooms. These bowl shapes are available in different toilet types, including the one-piece, two-piece and wall-mounted flushing toilet.
4. The Flushing Technology
You cannot choose the best toilet with powerful flush without considering the flushing technology. This is because the strongest flushing toilet technology determines the toilet’s ability to eject waste while ensuring nothing is stuck to the sides. The following are the different flushing technologies you could choose from;
a) Dual Flush
This best flushing toilet technology allows you to select either a partial or a full flush. You could choose either a 1.1 or 1.6-gallon flush, depending on the contents of your elongated flushing bowl. That said, the 1.1-gallon dual flush is ideal for liquid waste, while the 1.6-gallon flush is suitable for solid waste.
b) Gravity Flush
The best toilet with powerful flush that uses this technology depends on gravity to eject waste contents. The toilets store water in tanks, then generates flushing power from gravity to drain the water into the bowl and trap way.
Looking for the best toilet with powerful flush that is pocket-friendly? Consider one with a gravity flushing technology as they are easy to maintain therefore cost-effective.
c) Pressure-assisted Toilets
These are toilets with a pressure tank inside the system’s water tank. The function of this pressure tank is to increase the flushing power of the water as it drains into the bowl. While this flushing system cleans your toilet perfectly, it may not be your choice for the best toilet with powerful flush as it is noisy and can be difficult to maintain.
Looking to cut down on your water bills? Consider installing toilets with double-cyclone flushing technology. This system uses 1.28 gallons for every flush, so it consumes less water.
Double-cyclone combines gravity and pressure-assisted flushing technologies to eliminate waste, making it the strongest flushing toilet and is common with Toto flushing brand. It is worth noting that the double-cyclone technology opts for two nozzles and not the usual rim holes common with other flushing units to eject waste.
5. Water Consumption
When looking for the best toilet with powerful flush, you should consider its water efficiency. Often, the toilet contributes 30% of the water used in households, so you should opt for a water-saving unit. You should purchase a unit with a lower GPF to lower your water bills.
You could further go for a unit with a dual flush system to regulate the amount of water to use depending on the contents in the bowl. A Toto flushing toilet uses 1.28 GPF; therefore, it is a pocket-friendly option to save on water consumption.
6. The Toilet Material
The material used to make the flushing toilet determines its durability. Most flush toilets are made from vitreous china, ceramic and Porcelain materials. You should go for toilets with ceramic and porcelain materials as they are long-lasting and durable.
That said, it is worth noting that the more durable the toilet material is, the more expensive it is likely to be.
7. The Design and Color
While choosing the strongest flushing toilet is crucial, ensuring that the unit blends with your bathroom decor is equally important. So you should choose the best flushing toilets with designs and colors that complement your home’s appearance.
8. Noise Level
The best toilet with powerful flush should produce the least noise. This is crucial, especially if you intend to install the toilet next to a baby’s nursery or bedroom. To determine the noise produced by a specific elongated flushing system, you should consider the flush’s technology. The gravity flush model is best for flushing toilets as they produce the lowest noise levels.
Some toilets that use alternative powerful flushing technologies such as the dual flush system, or pressure-assisted unit, to mention a few, have a fill-flush valve that allows a quiet flush. That said, ensure that you purchase a unit with a quiet closing toilet lid to avoid the loud banging noise when locking the system.
9. The Brand
When choosing the best toilet with powerful flush, you should consider the unit’s manufacturer or brand. This is because the toilet’s brand contributes to the quality of the unit you purchase. But how will you identify a reliable brand?
