There are numerous one-piece toilets, and finding the best one piece toilet models for your household may seem like an overwhelming task. Finding the perfect one for your bathroom involves locating one that is stylish, fits your decor, is suitable for your budget, and fits the space. Keeping all these things in mind when buying a toilet can be exhausting!
Things to Consider
With hundreds of toilets flooding the market, make sure that you purchase one that is ideal for all family members. Since toilets are one of the most important features in a bathroom, it not only needs to be functional, but also aesthetically pleasing while complementing the style of your bathroom.
Dimension and Size
What makes one-piece toilets beneficial is they are smaller than traditional ones. This makes them perfect for smaller bathrooms or powder rooms, and they allow for more floor space. Check the toilet’s dimensions prior to purchasing and pay attention to the distance it protrudes from your wall.
Shape is equally important. Toilets come in round and elongated sizes. Traditional ones are round, while elongated toilets extend further forward and provide greater comfort. Comfort is additionally important in a toilet, as some of us may spend quite a bit of time in the bathroom. There are square and rectangular designs available for purchase.
One-piece toilets come with either dual flush or standard flush. Standard flush does not have a variation in the amount of water per flush. Every time the lever is pressed, it provides the same amount of water. This full flush is not as effective at saving water.
Dual flush systems incorporate a partial and standard flush. Partial flushes remove liquids, while full flushes are for everything else. Partial flushes are also quieter than full flushes. Measured in gallons per flush (gpf), partial flushes use 0.8-1.2 gallons per flush. Meanwhile, a full flush uses 1.5 gpf.
Whenever possible, examine the height of your toilet seat. Generally, 16.5” is the standard height. For people who are smaller in stature, toilets that are 16” may be more comfortable. However, if you have anyone in your household with mobility challenges, this may not be a good choice as they may struggle to get up and down.
Seats should be 16.5” from the floor to be ADA compliant.
Is the Seat Included?
Not all seats are included with a toilet. Some one-piece toilets may contain unusual dimensions. Purchasing a replacement seat or a new one may cost more and be more time-consuming to locate due to an odd size. Lids that offer a soft close are wonderful if you don’t want to hear dropped lids, or if children are sleeping.
