TOTO Aquia IV 1G WASHLET+ C5 One-Piece Toilet and Bidet, 1.0 & 0.8 GPF, Universal Height

If you want to upgrade your bathroom with an efficient new toilet plus a top quality bidet seat, TOTO’s WASHLET+ systems are for you! These specially designed toilet and bidet pairings keep the bidet’s water and electrical connections hidden from view for an elegant, streamlined look. Plus, these systems are less expensive (and more traditional looking) than TOTO’s integrated bidet toilets, so they’re a great option if you’re renovating on a budget.

With an elegant silhouette and a powerful, high-efficiency flush, the Aquia IV 1G toilet is a perennial customer favorite. This one-piece model features a chic push button on top of the tank and provides two water-conserving flush options: 1.0 gallons and 0.8 gallons. With a seated height of 17-5/8″, it’s also easier to get on and off this toilet than a standard height version.

The C5 WASHLET (bidet seat) offers a lot of bang for your buck! Notable features include front and rear wash modes, pulsating and oscillation spray options, heated seat, a warm air dryer, a deodorizer, and nozzle sterilization with electrolyzed water. The C5 comes with a sophisticated wireless remote that can be mounted to the wall for easy access.

If you want to upgrade your current bathroom with a brand new toilet and bidet seat from one of the most trusted companies in the business, a TOTO WASHLET+ system is the way to go!

*Note: WASHLET+ toilets can only conceal the cords and hoses of the WASHLET+ bidet seat it came with (and other select models). WASHLET+ bidet seats can only be installed on compatible WASHLET+ toilets. Reach out to our support team if you have questions about fit.

What our Customers Have Written About us

I discovered Many Bidets through their excellent series of YouTube videos. Very informative in helping with general understanding and specific models and features.

I became sold on Many Bidets through their pre-sales support and advice. I had several questions which I asked both through Chat and via telephone. Both experiences were outstanding - no pressure just clear explanations. They even did some research for one of my questions.

They were proactive in following up after delivery in case we had any questions or problems.

All at very competitive prices!

Many Bidets is a smaller family owned operation but don't let that shake you. They handled my business with a personal touch that you can not get from a major online outlet. Dan made sure that I got the seat I wanted, with the features I needed and beat the best price that I could find anywhere else on the internet.
Once I made the purchase, the seat was delivered in 3 days. Many Bidets has since followed up twice to make sure that my install went well ( it did and it was very easy ) and to make sure I was completely satisfied with my seat.
I am very happy that I found Many Bidets and if there are any bidet purchases in my future, they will be the first company I contact.

If you are looking for honest reviews, got to their YOUTUBE page where the boss talks honestly about the actual functions, features, and perks of their top Bidets. Thats how I made my choice.
Dealing with them was not only easy but a pleasure. My bidet showed up days after I ordered it. The online install video was SUPER helpful, and last but not least they helped me online in the chat when I was narrowing down my choices.
It might seem like I'm gushing, but after walking into a few grocery stores where people just shrug and tell me they don't know where the ICE is... this was Customer Service:Advanced Edition and my experience couldn't have been any better!

Because you were very easy to talk
with, knew your products and
ordering was very easy. Because I purchased from them before and it
was a very satisfactory experience!
Joanne H

It was very easy to order, and the bidet arrived quickly. They had the best price for the bidet we wanted.
Nicole D

Staff is extremely helpful and friendly. They were quick to answer my questions, deliver a quality product and even personally follow-up up after delivery to ensure everything was up to our satisfaction.
I would highly recommend this company to anyone!

Many Bidets says it's a family owned business; and believe me it treats you as if you're part of that family too. I recently made a purchase and I was immediately impressed by the service. Dan, the owner, was very friendly and professional, responding to all my concerns. He understood that, like other customers, I wanted the best quality product that fit my budget and to be happy and confident about my purchase. Believe me I got all of that and more. Delivery was super fast, the product was as described, the price was also reduced beyond the advertised discount. Dan followed up to make sure I was 100% happy with my purchase.
Recently, I had a question involving the manufacturer of a product I had purchased, nothing to do with excellent service at Many Bidets. Instead of merely referring me to the manufacturer, Dan stepped in when he didn't have, to make sure everything worked out to my satisfaction. That's the kind of customer service that Many Bidets provided. I would highly recommend dealing with Dan and Many Bidets if you value excellent all-round service, quality product at a great price, and peace of mind.

I’ve purchased twice from Many
Bidets with fast service and good interactions both times. The
products they sell have served me
well and are of a good quality. I
would recommend them to anyone else looking to buy a good product and receive the best discounts.

Fantastic experience dealing with this company. Great price, fantastic response to questions, and delivery was actually ahead of schedule of when they said it should arrive. Delivery was professionally handled and well communicated.
I am a sticker for detail and had a fair amount of questions during the purchase. Each communication was dealt with promptly.
I would use this company again if possible in the future.

Great price, selection and finish options. The customer service agents are very responsive and the delivery process was very clear and well explained. They also followed up after delivery to check on the install and product. I would definitely order from here again and would recommend this place!

Profile Picture Romina Perez

I had originally reached out to Many Bidets through email because I had a question about which type of bidet would fit a one-piece toilet. Someone emailed me back very quickly on a Sunday and was SO helpful. I ended up working with that person directly to then go on and purchase my bidet seat through the company. When it arrived I had some questions involving installation and they answered my email immediately. Their customer service and response time is incredible! Don't give Amazon your money when buying a bidet. Use these guys!
