Our daughter fell in love with the bidets at her office then put them in her house. We visited and decided they were nice. Now we have them in our new build house and are very happy campers.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
Well, if using about 75% less toilet paper and having a much cleaner undercarriage is life changing, then yes. Yes it has.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
Absolute game-changer for our house bathroom. The design is clean, and every single feature works good!
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
Obsessed with this smart toilet—it's an absolute game-changer for my NYC apartment setup! After ten days of use, the design is sleek, the footprint is apartment-friendly, and every single feature works like a dream.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
I’m kinda a clean freak, so the UV nozzle sterilization is probably my favorite feature. It helps keep the nozzle cleaner between uses and gives me extra peace of mind. Small detail, but huge for me. Really happy with this toilet so far.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
I just finished renovating my home in a clean, modern minimalist style, and this toilet fits in sooo well. The sleek, simple look goes perfectly with my bathroom—it feels polished without being flashy. As a woman, I especially love the feminine wash setting and warm water; honestly, it’s a total game changer. The hands-free lid and foam shield are such nice little extras. I’m def obsessed lol… I’m not going back to a regular toilet anytime soon.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
I am so impressed with this smart toilet! The remote control panel is incredibly responsive—the buttons react instantly with zero lag, making it super easy to adjust the settings. As a woman, I really want to highlight the feminine wash feature. It’s gentle, positioned perfectly, and works like a charm. It honestly makes such a difference in my daily routine.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
We just finished remodeling our bathroom, and I’m so glad we went with this smart toilet. It looks great in the new space, and there are so many features I’m excited to try. Still getting familiar with all the settings, but no regrets so far! Looking forward to using it more now that the remodel is finally done.
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
Looks great in our bathroom. Love the simple design. Really happy with it so far!
SERIN Smart Bidet Toilet with Auto-Open/Close Lid, Foam Shield, UV Nozzle Care & Child Wash
You can see the paper moving in the airflow from the dryer. It looks like there’s a decent amount of air coming through.
The night light gives enough light to see the bowl clearly, but the glow is still soft. Handy for nighttime visits.
The foam comes out quickly and looks nice and dense. It takes just a few seconds to form a layer on the water.
The foot sensor is pretty responsive. Just move your foot near it and the lid opens—no need to lift it by hand.
Posting a close-up because I had a hard time finding a real photo of the display before ordering. It is easy to read when you are standing next to the toilet, but it is not so bright that it lights up the bathroom at night. The water temperature has stayed consistent and the seat warms up quickly. The black panel does pick up a little dust, which is noticeable in direct window light, but a quick wipe takes care of it. We have had the toilet for just over a month and everything is still working well.
We bought this for our primary bathroom because our old toilet had a separate bidet attachment that was awkward to clean around. We have been using the SERIN for almost two months now. The foam feature was not the main reason we chose it, but it has ended up being one of the most useful features. There is less splash and the bowl does stay cleaner between regular cleanings. The warm-water temperature has been consistent, and my husband and I can adjust the wash settings easily from the remote. I also like having the UV nozzle care between uses. It was not a small purchase, but it feels like a real upgrade rather than just a gadget.
This picture was taken before we finished cleaning up, so the box and tools were still on the floor. The toilet is heavy and getting it through our small doorway was honestly the hardest part. Two people definitely made that easier. We measured the space and checked the outlet location before ordering, which I’m glad we did. Once it was in position, our plumber had no issue making the connections and it powered on correctly the first time. We have only been using it for a few days, but so far the wash, heat and automatic functions are all working properly.
The controls looked a little intimidating when we first unpacked everything. The side control is easy enough for the basic functions, and we use the remote when we want to change the water temperature or wash setting. I do think the instructions could explain the remote better because we had to go through it a few times. After the first week it became pretty automatic. The glossy dark panel does show fingerprints and water spots, but they wipe off easily. Taking off one star mostly for the learning curve, not for how it works.
I took this photo at night so the color looks a little yellow, but the toilet itself is a normal clean white. We’ve been using it for about six weeks. The heated seat and warm water are the features I notice most, especially when I get up early in the morning. The lid sensing has also been working consistently and it is quieter than our old toilet when it flushes. I didn’t think I would care that much about a smart toilet, but now the regular one in our other bathroom feels very basic.
Put this in our downstairs guest bathroom. We already had an outlet close by, so the installation was pretty straightforward. It fits the room better than I expected and doesn’t make the bathroom feel crowded. Looks good and works well.
We went back and forth between buying another bidet seat and replacing the whole toilet. Since we were already updating this bathroom, we decided to go with the all-in-one and I’m glad we did. We’ve had it for a little over three weeks now. The warm water comes on quickly, the seat heat is comfortable, and the hands-free lid is one of those things that felt unnecessary until we started using it every day. The remote has more settings than we will probably ever use, so it took us a few days to figure out what we actually liked. Our bathroom is narrow, which is why I took the photo from the hallway, but the toilet doesn’t feel oversized in the room. So far everything has been working as expected.
