Best compact toilet buyer’s guide

 Size of the toilet

Typically, the length and width of the toilet are not of great importance, but the distance from front to back is really crucial. Always consider going for a shorter toilet so that you can shade off some inches.

Water usage

In the past, toilets used up to 6 gallons of water per flush, but this has changed a lot with today’s toilets. Look for the best compact toilet that uses 1.28 GPF or less than 1.6 gpf. This helps conserve water and reduces the water bill.

Flushing system

The two most popular flushing systems are gravity flush and siphoning action. Choose the right flushing mechanism if you want to flush effectively.

Type of toilet

It can either be a one-piece or two-piece toilet. One-piece toilets take up much lesser space than two-piece toilets because they have the tank and bowl integrated into one unit.

Ease of installation

One of the advantages of having a two-piece toilet over one-piece is that they are easier to install. They come with a separate tank and bowl, which makes them easy to set up, unlike the heavy one-piece toilets.


Round bowl toilets occupy the least space, but the most recent compact toilets come with elongated bowls as manufacturers have come up with compact designs that fill the same space as round bowl toilets.


Pick a toilet made of the best durable materials on the market, such as vitreous china. Ceramic is also great but not anywhere close to vitreous china.


Pressure-assisted toilets have the most efficient flushing system, but they are also the noisiest. Choose a gravity-fed toilet with a good performance but very little noise.


Ensure that you pick a toilet with a warranty as reputable brands offer warranties on their products. This will help you in case you get a damaged product or one with a defect in material and workmanship. The warranty can be on mechanical parts, chinaware, accessories, or even seat.

A small bathroom space can be fully utilized by installing one of the above compact toilets. You no longer have to sacrifice some features found in standard toilet when installing a compact toilet. Pick the best compact toilet that is elegant but with the features that you desire. From elongated bowl design to a high-efficiency, and powerful flushing system, getting a compact toilet that performs outstandingly is now easy. Just pick the right toilet for your bathroom needs and have a great experience.


Question: Are compact toilets difficult to clean?
Answer: No, they are not. This is because you use the same cleaning techniques as you would with a normal toilet. Also, depending on the technology that the toilet comes with, some are even easier to clean than standard toilets.

Question: What’s the best way of preventing mold from developing behind the toilet in the bathroom?
Answer: Mold and mildew easily develop behind the toilet because of the damp conditions. To avoid this from occurring, you need to ensure that there are o leakages, keep humidity levels in the toilet at a minimum, and ensure that there is good ventilation in the toilet.
