Inax 8013A Bidet Review

Please note that this page may contain affiliate links.

Inax is a well-established Japanese bidet brand with a long history. Along with Toto, they are one of the leading bidet seat brands in Japan. However, since they don’t have a large selection of bidet seats for the US and Canadian market, many people may be more familiar with the Toto brand than the Inax brand. Whether you buy a Toto or an Inax, it’s hard to go wrong. The most important thing is to pick the model that works for you. Here, we’re going to take a look at the Inax 8013A bidet seat, and by the end you should be able to see whether or not this is the bidet you want to buy!

INAX 8013A bidet


To start, we’re going to take a look at the design in terms of its appearance, dimensions, and built.

The first thing you will notice about this bidet is that it comes with an attached control panel that would be on your right side when seated on the toilet. The buttons are big and the layout is easy to follow. There are three large buttons for “Stop”, “Cleansing” (rear wash), and “Bidet” (feminine wash). Next there are adjustment buttons for the “Spray Strength”, “Nozzle Position”, “Seat Temperature” and “Water Temperature”. If you press the “Seat Temperature” and “Water Temperature” together you will be able to extend and pull out the nozzles (there are two) for cleaning. And finally there is an “Eco” power saving button and a “Massage” button that activates the massage function.

The Inax 8013A is available in elongated design only. This could be a problem for you if you have a round toilet. You should be able to see what kind of toilet you have fairly easily – a round toilet has a circle shape and an elongated toilet has an oval shape. Precisely, elongated toilets are about 18.5 inches long from the mounting bolts at the back to the front, and round toilets are about 16.5 inches.

The Inax 8013A bidet will fit most elongated toilets. Its dimensions are 21-1/16″ (the back of the hinges to the front most part of the seat), 18-14/25″ (left most point to the right most point on the seat), and 6-22/25″ (rim of toilet fixture to the highest point on the seat). At less than 7” tall this bidet seat is nice and slim!

The Inax 8013A comes in Canvas White.


It would be wrong to talk about a bidet seat without starting off with the cleansing function first! The Inax 8013A has a highly customizable spray. There are two nozzles for front and rear cleansing. And you can enjoy five different spray patterns: rear, rear oscillation, rear massage, front (feminine), and feminine oscillation. Oscillation means that the nozzle will move forward and backward so that you can clean a wider area.

As we mentioned already, the spray of the Inax 8013A is customizable.  Besides spray pattern, you can adjust the water pressure and temperature to 5 different levels. The minimum water temperature is 90°F/32°C and maximum water temperature is 104˚F/40˚C which, comparatively speaking, gives you a wide water temperature range. For most people, the ideal temperature is generally at 38˚C, give or take 2˚C.

A neat feature of the Inax 8013A bidet is that it has a seat and lid that closes slowly and softly. You can detach the seat quickly with a single click when you want to clean the area around the bidet. There is also a deodorizer with the bidet seat that works by charcoal filter cartridge and helps keep your toilet smelling clean.

A useful feature of this bidet is the Eco function. This function shuts off the water and seat heater for 8 hours (which is useful during the night when the toilet isn’t used). This is a particularly useful function for this bidet seat because it uses a tank heating system where water is kept warm in a reservoir. This kind of system requires energy to keep water warm so that it can be ready to use at all times. The Eco mode allows you to save energy when the bidet is not in use.

Why the Inax 8013A bidet?

Buying a toilet seat bidet is a huge investment. After all, you’re going to be sitting on it multiple times a year for many, many years. You have to make sure that you get one that suits your needs (which is why you’re reading this, of course!). To help with your decision, we put together some reasons why the Inax 8013A might be the one you’re looking for.

You should buy the Inax 8013A if:

  • You want a bidet toilet seat with a heated seat, warm water, and customizable cleansing
  • You want an attached control panel
  • You want a bidet seat that will help you save energy with an “eco” mode
  • You want to maintain a clean, odor-free toilet with relative ease
  • You have a 3-prong plug near the toilet or are willing to install one
  • You want a quality bidet made by a reputable Japanese company
  • You want to spend less than $500


One major drawback with this bidet seat is that it doesn’t have an air dryer. Besides the wash and heated seat, most people want an air dryer with their bidet seat as a minimum. So if you’re looking for this feature, this bidet seat may not be for you. The other drawback is you’re out of luck if you don’t have an elongated toilet, as the Inax 8013A is only designed to fit elongated toilets.

If you want a bidet that is similar in price and function to the Inax 8013A and has an air dryer, then we recommend getting the Toto C100. The Toto C100 is available in elongated and round versions, so it should work for most people too. The Toto C100 also has a couple of other neat features that make Toto stand out from some of its competitors. Check out our Toto C100 review to read all about it.

Final Thoughts & Where to Buy

This Inax bidet is very beautiful. It’s a well-designed product – as you would expect from a Japanese company. The cleansing function is its major selling point. Front wash, rear wash, massage, oscillation – whatever you need, it will deliver, and you can adjust it to your preferences. If you don’t need an air dryer with your bidet, this is one of the best bidet seats in terms of cleansing function and quality that you can get. And did we already mention how beautiful it looks?
