Frequently asked questions (FAQ) about toilet bidet seats

How much power do bidet seats draw?

Tank-type bidet seats generally draw a maximum of 600W at their peak, while tankless-type bidet seats draw up to 1400W. However, a bidet seat will only draw a high wattage during an active wash cycle when all temperatures are set to maximum levels. It may be 4-5 minutes per day. Most of the time, the bidet seat will be sitting idle with a very low power draw (especially if eco modes are active). They do not require dedicated circuits so long as there aren’t any other heavy appliances active on the same circuit. 

Features to consider while buying toilet bidet seat or washlet:

There are several features you should consider while buying a washlet. Such as-

Standard features:
Most toilet bidet seats have standard features such as a heated seat, hot water, warm air dryer, front feminine wash, and rear bidet washing modes. You should check the availability of those features. The other features, such as the water temperature, spray pressure, nozzle positioning, and seat temperature, should be adjustable.

Unique features:
Bidet seats may have some unique features that set them apart, like an automatic opening/closing lid, LED night light, etc. When comparing the various bidet models, you’ll need to decide which of these features is most important to you.

Size compatibility:
Before buying a bidet seat, you should first make sure you have a compatible toilet. So, you must find out what kind of toilet you have.

Spray pressure strength:
The strength of the spray is a very important feature. Some users prefer a gentle spritz, and others want a blast. Therefore, most models have an opportunity to adjust the spray pressure to do the job as per your expectation. You may buy a bidet seat specializing in higher spray pressure for those looking for extra strength of spray pressure.

Warranty coverage:
Warranty coverage is also an important point for the bidet comparison factor. A longer time warranty is always a great thing to have in your back pocket. Most models offer one to two to three years of warranty coverage, and some also have optional extended warranties. Make sure to pay attention to what’s covered as part of the warranty.

Brand reputation and reliability:
Warranty coverage is also an important point for the bidet comparison factor. A longer warranty is always great. Most of us have a horror story about an expensive item bought and having some issues. This can happen to anyone. However, what makes the experience truly horrible is when the company that produced it doesn’t stand behind it. Buying a bidet seat is no different. So, we always recommend buying products from a reputed brand. At least you can get great support if there any issue arises after your purchase.

Mistakes to avoid while buying a toilet washlet seat:

Not having an electrical outlet nearby:
The vast majority of bathrooms do not have an outlet near the toilet. Although it may seem funny, a few individuals purchase an electronic bidet seat and have no idea they need an electrical outlet. Electric bidets do not run off batteries, and all models need to be plugged into an outlet.

Purchasing the wrong size bidet seat:
It is very troublesome to purchase the wrong size bidet seat. It is very important to understand whether the new bidet size is compatible with your toilet or not. 

Buying less when expecting more:
A bidet seat is a home appliance used daily, multiple times a day, often by multiple members of a single household. You should buy the cheapest option possible just because “it’s a toilet seat.” Think of buying a bidet seat as a long-term investment regarding your health and hygiene. For a long time use and a hygienic lifestyle, you should buy something dependable and high-quality product.

Not knowing the difference between a tank, tankless, and hybrid heating bidet:
When buying a bidet toilet seat, a key feature is what kind of water heating system it uses: tank, tankless, or hybrid. The difference in performance can influence the overall experience of your bidet seat.

Unrealistic expectations:
Bidet toilet seats are incredible hygiene devices that can change your bathroom habits. However, the toilet washlet or bidet seats are not miracle products. Using a bidet will be a positive life-changing experience, but a huge mistake some users make of having unrealistic expectations for what they can do. Doing a little research is the best way to avoid making mistakes while buying a bidet toilet seat.

Things to notice:
Before buying a washlet, be sure about each & every detail and how it should be implemented & how to use it. Sometimes lack of knowledge may lead to unexpected failure of product functionality. The device may get damaged within a few days & you can get yourself hurt. It is necessary to be realistic about your expectation. You should know your budget and what you’ll be getting at the desired price range, understand the sizing of a bidet seat, and know what features you want.
