It was once very rare to see a bidet seat sell for around $100. That price range was usually limited to add-on units that, while effective, had equally limited features.
The Slim Zero from Bio Bidet is starting to change all that. It lacks some of the features of higher-end models but delivers many of them at a substantially lower price than usual.
Basic Features
Like higher-end bidets, it’s a replacement for your standard toilet seat. As such, it houses a pair of spray wands under a slow-closing seat and lid, along with controls that make it easy to maximize comfort and hygiene.
Among those controls is the ability to adjust the pressure. You can select front or rear cleansing by an easy push backward or forward on the side lever. One thing that requires a little more care with this simple bidet is remembering not to get off the seat with the water turned on. Many high-end units will automatically shut off the spray, if you do. There’s no sensor here; the lever operates a simple on-off valve.
One other limitation of this low-priced model is that the spray is strictly “room temperature”. There’s no electrical warming mechanism and no ability to hook it up to your hot-water supply. So, whatever the temperature of your home’s water supply is at the toilet valve – and that will vary from summer to winter in a lot of places – that’s the temp that strikes your body. For some people that will be just fine; for other buyers that might be a deal killer.
The Slim Zero also lacks a seat warmer, but I suspect fewer buyers will miss that. It gets pretty cold some winter mornings where I live, but I very rarely use my own bidet’s seat warmer.
There are other “nice to have” features. One that surprised and delighted me when I installed other bidets is shared by this model: a night light. I didn’t anticipate how helpful it would be to have a glowing light in the interior. But like a lot of people, I sometimes get up in the middle of the night, and it’s a big help not to have to turn on the room light.
Since there’s no electrical hookup, the light is powered by four AA batteries, but you’re not likely to need to replace them very often. Anyway, they’re simple to remove and insert by extracting and re-installing a little tray on the side.
Installation
Another aspect potential buyers should consider is installation. It’s easy, but some buyers not so skilled at do-it-yourself projects might need some help.
Unfortunately, the Slim Zero comes only in an elongated version, so be sure to measure your toilet carefully before moving ahead, to ensure a good fit. This seat will fit your toilet as long as there is 1.5 inches of space between the tank and seat bolt holes and 5.5 to 7 inches width between the seat bolt holes.
Like higher-end units, you still have to integrate this unit into your toilet’s water supply. That requires care with plumber’s tape to ensure no leaks, as well as some strong fingers or a facility with a wrench. You’ll need enough space around the toilet base to get everything in place. That won’t be a problem for most buyers, but measure carefully.
During the installation (and for long afterward) you’ll be pretty pleased with the parts. The valve is brass, excellent for long-term durability, and the hoses are well made of PVC and metal. There are mounting bolts of metal or plastic (with rubber nuts or plastic butterfly nuts), whichever better suits your circumstances and preference.
By the way, there’s a 1-year warranty so you’re covered for any problems well-beyond the usual return period at your hardware store or online vendor.
Summary
The Bio Bidet Slim Zero offers a highly functional bidet at a relatively modest price. It doesn’t have the water warming and drying ability of more expensive models but you can adjust the pressure. And the dual nozzle system enables both posterior and feminine wash. A lot of value for a low price.
