Factors to Consider When Buying a Dual Flush
When it comes to picking a dual flush toilet there are a few things to consider:
For some it is important to consider the overall height of the compact toilet. Some compact toilets, while they may be considered a space saving toilet can still take up vertical space; therefore, when shopping for a compact toilet it is important to consider whether you want one that is a shorter toilet than the standard height or if a low height toilet suits the compactness you seek.
The shape of a toilet seat is just as important as the height. It is important to consider whether one wants a compact elongated toilet or a round compact seat. Comfortability and safety is an important consideration for the seat shape. For a narrow toilet the seat will most likely be compact; whereas, standard, low profile toilets may be round. An added feature that one may consider when shopping for a compact toilet for small bathrooms is whether the seat itself can be interchangeable – if so, this does open up the options for a compact toilet.
While the name says it all – compact toilet, it is still important to consider the overall space that one has to work with when purchasing a compact toilet for small bathrooms. One thing to consider is the measurement from the front to the back of a toilet, some may be not take up that much space or they may be awkward to install; therefore, knowing where and how you plan on installing the toilet will help when doing the research before the purchase. Compact toilets may be ideal for a tiny house with minimal space and the best way to add functionality and space is to go with a toilet suitable for small space – but it is also just as important to ensure you know the exact space you have to work with.
When it comes to the compact toilet, height can be an important consideration especially if users of the compact toilet are the elderly or they lack mobility. While they may be compact, they don’t necessarily have to be a low height toilet – if anything, a compact toilet can have the characteristics of a standard height toilet. It is important when purchasing a compact toilet that if one chooses to go with a short toilet, they make sure no one will be uncomfortable using it.
Choosing to go compact means purchasing a small tank toilet in comparison to standard tank toilets that can be add extra length from back to front. Going with a compact toilet means some brands will offer a smaller tank that doesn’t jeopardize functionality or aesthetic appeal. Picking a compact toilet for small bathrooms means considering the tank as well.
When buying a dual flush toilet- whether it be tankless, wall-hung or technologically advanced or even ADA approved – testing the unit can prove beneficial and even essential. Knowing the amount of space, the type of plumbing or wiring needed will help with making the right purchase. Knowing something such as the plumbing can help ensure that the water pressure will be no issue, especially when it comes to a dual flush toilet. Most toilet brands will offer a single flush while also offering a dual flush alternative. Purchasing a dual flush toilet is often a smart investment for those conscientious of water consumption but feel that a dual flush system may jeopardize quality. It does not, consumers can rest assured that the quality is there and all that is left to consider is the features as well as appeal and style desired. Not only is the outer appeal important but choosing one that will offer comfort in seating, height and feel. Selecting a compact toilet and factoring the reduction in height and considering the shape of the bowl will enhance the comfortability and support of a toilet for a user.
No matter your budget, we at Best Toilet Guide break down the pros and cons of the best units available. From toilets certified as WaterSense to two-piece and one-piece models, pick a toilet that not only matches your budget but your needs as well. Don’t be limited the next time you are on the lookout for a toilet—consider factors such as height, which can impact not only the placement of the toilet but also the functionality of a single or dual flush and accessibility of it as well. Other factors that might not be as important to some are colour, shape, and if the lid has a built-in closing mechanism preventing it from slamming when closed. These added features and ratings can enhance a toilets functionality and also its safety features, which for some toilets can mean it is suitable in family and elderly home residences.
The next time you search for a new toilet, remember that just because it’s a higher-end model, doesn’t mean it’ll meet your needs. Always consider what you are looking for before making that purchase, or you just may be flushing your money away.
