TOTO WASHLET+ Aquia IV Cube Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet with Auto Flush S7 Contemporary Bidet Seat, Cotton White, Vitreous China|Plastic, MW4364726CEMFGNA#01

The TOTO T40 WASHLET+ Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and Contemporary Auto Flush WASHLET S7 Bidet Seat is designed to conceal the WASHLET power cord and water supply hose for a seamless installation. The WASHLET S7 features TOTO's technologically advanced EWATER+ system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The TOTO WASHLET S7 is operated by a luxury style illuminated touch button remote with 4-user memory storage to save preferred settings. The WASHLET features 5 spray settings, Auto Flush, heated seat, a nightlight, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamlined look and giving the impression of an integrated system. This minimalistic display provides a more subdued appearance to your WASHLET. The sleek tank design coupled with the skirted bowl create a sophisticated look and minimizes the need to reach behind the bowl to clean in between the nooks and crannies of the exterior trapway. The Universal Height design allows for a more comfortable seat position across a wide range of users. The Aquia IV features TOTOs DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. CEFIONTECT, EWATER+, and DYNAMAX TORNADO FLUSH create a synergy that optimizes flush performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. New Auto Flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush. Allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines.

Great product!
Style: 30 sqft
I can say this product makes a huge difference with road noise and is cleaner and easy to work with when applying compared to other mats that cost about the same price.

Very heavy and thick
Style: 30 sqft
I purchased mini brands of sound ending and this is by far the heaviest sound deadening I've ever ordered. I'm not installed yet but I have a good feeling that is going to work exceptionally in blocking sound. If weight is a concern for you I would recommend a lighter product however if sound quality and a quiet ride is your priority this is the one for you.

Siless Hybrid 3-in-1 - Far Exceeded my Expectations!!!
Model: SLH20025
I recently installed the Siless Hybrid 3-in-1 sound deadening mat in my vehicle, and I’m genuinely impressed. For just $80 for 25 square feet, this product delivers performance that rivals materials costing twice as much — and with far less hassle. If you're on the fence......Just buy it! You will not be disappointed. Easy to Install: Unlike traditional sound deadening products that are stiff, sharp, and temperature-sensitive, this mat is soft, flexible, and easy to work with. I cut it cleanly with regular scissors and pressed it into tight spaces using just my fingers, so if in you don't have a roller or install tool, a good pair of scissors and your hands can get the job done. With other brands like Dynamat, the aluminum layer often leaves micro cuts on your hands and tears up your fingertips, but Siless does not due the acoustic layer being on top and above the aluminum layer that holds the butyl layer. So, it's very easy on your hands. Even in cooler temperatures (around 50°F), I had no trouble applying it but it goes on better heated. If warm outside, I would leave the entire box out in the sun for at least 30 minutes when it's warm or heats it's very pliable and easy to mold. Make sure its where you want it because once applied it's not ever falling off. and it became even more pliable and easy to mold. No heat gun, no mess — just straightforward application. I installed 40–50 square feet throughout the interior, covering everything except the headliner and the flooring forward of the rear seat. The difference in cabin noise is astonishing. I can turn my radio up concert loud with gut-punching bass, and from outside the car, it sounds like a factory sound system at mid volume. I was blown away by how well it contains sound — both inside out and outside in. My exhaust is pretty aggressive and now is barely audible from inside the cabin. While driving, it almost sounds like a stock factory setup. The Siless matting actually changed the driving experience and feels refined. If you're skeptical about sound deadening gimmicks, I get it, but this is the first product I've used and when I needed more, I went Stright to the 3 in 1 Hybrid matting and purchased it again. I love researching before buying and that's very uncommon for me to do. Note: Proper installation is key, and it does take time and patience. But if installed correctly and in the right places, it works better previously used from paint-on sound deadening to Dynamat. Update Nov, 2025 After using it this in 4 separate vehicles now. I feel the Siless’s 3 in 1 Hybrid has nailed it for best budget deadener that is better than dynamat extreme in performance and installation Protip: buy a roll of 2-3” aluminum tape and tape the seams. After trimming the edges tend to very sticky between the panels. I ran a strip of aluminum tape over the seems to create a better seal and true moisture I used it on four vehicles now and have I have not been paid to review and purchased every order myself. 3 in 1 Hybrid deadener by Siless is the best all around easy to apply sound deadner period!

Top quality
Model: SLH20025
This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels. After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell. At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.

Made a big improvement in cabin noise—highly recommend
Model: SLH20025
Siless Hybrid made a huge difference in reducing noise in the floor of my truck cabin. In some areas, there was basically just bare sheet metal between the inside and outside, so adding this really helped the truck feel more solid and noticeably quieter on the road. I used Kilmat on the doors, and honestly I wish I had used Siless Hybrid there too, but it was too late by the time I realized the difference. This material is very sticky, easy to cut, and simple to apply, which made the install pretty smooth. Just a heads-up: the tacky side gets messy and will bond to clothing really easily, so be careful during installation. Overall, I’d definitely buy it again—great product with real results.
