How To Choose The Best One-Piece Toilet: A Guide
When looking to buy an efficient one-piece toilet, you may want to consider performance, comfort, and convenience in terms of the features that the product provides.
Calculate the size and rough-in dimension
It is important to measure the distance between the wall and the seat bolts as they can range anywhere between 10 to 14 inches. You would also need to measure the total distance of the bathroom to see if the one-piece toilet fits perfectly.
Select the ideal bowl height
Ideally, the bowl height should be between 14 to 18 inches for adults and 10 to 14 inches for children. Make sure you are aware of the height so you can conveniently get on and off the toilet.
Choose the bowl shape that best suits your need
Toilet bowls may be round or elongated and it is important to make sure that you choose one that fits your bathroom space and design perfectly.
Decide on the type of flushing system that you would like to use
Ideally, the flushing system should be convenient and powerful so you wouldn’t have to worry about re-flushing. Certain options even come with a hands-free flushing option that may work better for some.
Consider water efficiency
Saving water usage is an exceedingly important factor when it comes to selecting an ideal toilet. Most toilets are efficient and use a 1.28 GPF that ensures saving time and water resources.
Features Of One-Piece Toilets
Easy to clean: The best one-piece toilets have no tough corners that make cleaning a difficult task. Instead, you will not require special cleaning devices because all it takes is a simple washcloth and some cleaning solutions to get your product sparkly clean.
Easy to install: The one-piece toilet construction often arrives already complete and will only require connecting it to the plumbing system of your bathroom.
Leak-free: One-piece toilets are solid constructions and are less likely to leak because they do not have holes or junctures.
Durable and sturdy: Good quality one-piece toilets use a modern design with strong and durable materials, that tend to make them a long-lasting investment for your bathrooms.
Comfortable height: While larger toilets sit at 17 inches, the single-piece toilet comes at a comfortable height of 15 inches that makes it suitable for adults and youngsters alike.
Save space: Most one-piece toilets are compact and can fit in small spaces, making your bathroom look larger and allowing you to make room.
Save water: With one-piece toilets, water resources can be saved considerably.
Difference Between One-Piece And Two-Piece Toilets
Unlike two-piece settings, one-piece toilets feature an integrated tank and bowl. This construction eliminates the gap between the tank and bowl that tends to get dirty. A two-piece toilet is more popular because it is cheaper. As far as the tank and the bowl are separated, it is lighter to carry and less bulky and has a taller water tank. On the contrary, the joining area is a paradise for bacteria, grime, and dirt. It takes a lot of time to clean that area. Also, you should pay attention to the tightness of the junction to control possible leaking. I like a one-piece toilet more because it has a seamless design.
