C3 230 Lifestyle 01

The C3 230 toilet seat brings you the freshness of bidet cleansing in a slim, low-profile design made to fit most elongated toilets. This heated bidet seat comes with an easy-to-use touchscreen remote that allows you to adjust and set all your personal preferences, from water temperature and pressure to seat temperature and air-drying. A built-in night-light provides illumination of the bowl, and the self-cleaning stainless steel wand uses UV light for automatic sanitizing.

ummmm..kinda disappointed

lacks the stylized lines of the original, no way to keep the dryer from starting up upon sitting down, no discreet night light, uv cleaner activates in the middle of the night and strobes, is slighly longer than the rim of the toilet so fits poorly.

We replaced a Brondell whose seat cracked. I’ve been on toilet seats for 55 years, never a crack (other than my OEM of course.) No comparison!!

Kohler Bidet

The Bidet is wonderful! Originally I was exposed to a Toto while visiting this summer, but I like this product better. The nightlight is wonderful as is everything else about the product; thus, I highly recommend it.

Good but...

This is the second unit I’ve purchased through Bidet King. Highly recommend them for both price and selection. Much better than Amazon in my opinion.

This Kohler unit has some nice features. I particularly like the night time blue bowl lighting. It’s replaced the need for bathroom night lights with a distinctive blue LED radiance with helps find your way at 2 am. I also find the system controls easy to operate compared to my earlier system.

On the not as good list, number one peeve is the latching system that holds the seat to the bowl. It works loose way to easily and often. I’m in there forcing it to snap back into locking place weekly. I also find the water temp control isn’t nearly as effective as on my previous unit, giving me a slight chill when turned on.

Bang for the buck... as this is a premium unit, I’d have expected little things like the seat latch to be more robust. You’re paying for a brand name and somewhat elegant remote control.

Reeks of Kohler design and quality

This is the second Bidet product I received from BidetKing. The first product, a premium Bidet toilet seat, did not have a strong enough seat to support large people. After the replacement seat also failed, BK was willing to credit full price to purchase this unit. The step up to Kohler was welcome. The unit is sturdy and showed the Kohler design flair in bathroom fixtures. The seat seems stronger and positions you precisely. This may seem uncomfortable at first but consistent, precise, positioning is what makes the bidet functionality “hit the spot” every time. I loved the automatic seat lift on the unit I replaced. The Kohler lacks this feature but IMHO the automatic lifting seats (and lids) are made very light to lift and lower with small motors. The Kohler seat and lid are sturdier and have no weight or avoidance warnings (re:sitting on the lid). The seat is still two-piece to accommodate the heated seat feature. Living in So.Cal, I could do without that feature but most will love the comfort in the wintertime. The remote is really sharp-similar to an iPhone screen. The icons light up clearly. They require just the right touch so you don’t accidentally activate features. You can store settings so If someone messes them up all you do is touch an icon and your individualized preferences are restored. I greatly missed this feature on the brand returned. My only beef was that the installation manual was an “a” version. They are now on “d”. Kohler Customer service was incredibly responsive in replacing a bum part and emailing me the updated instructions. While on the phone he talked be through linking the remote and the seat and tested out features. Both BidetKing and Kohler have been 5 star in after purchase support. The Kohler remote is the best, by far, and the remotes on these units are ALWAYS used. Customization includes spray positioning, water and seat, and dryer heat. Everything easy to adjust and “savable” so you can restore without going through the whole process all over again. And one other Kohler WOW factor is that everything (fittings, wand, and hardware) are all stainless steel. Very little plastics in fasteners and hardware. Quite a difference from my first unit. Instructions clear (with updated manuals, downloadable). DIY is realistic with little skills needed. I hope it lasts with my size. The ultimate torture test. I’m glad BK added this unit to their product lineup.
