Wirecutter's pick for the bidet-curious: a cheap cold-water attachment that looks nicer than most and installs without an outlet. Its aim can't be adjusted, the water is cold, and CNN found its stream far less comfortable than the Tushy's. Amazon owners report some leaks at the T adapter.
Top complaints
- Cold water
Wirecutter says the most noticeable difference from electric seats is the lack of hot water. On Amazon, 571 reviews mention temperature, and 397 of them are negative; reviewers describe the water as icy or super cold.
- Fixed aim, so you have to shift around
Wirecutter says the spray position can't be adjusted, so plan to wiggle a bit. CNN says one knob handles front and rear wash, but you can't adjust the position beyond that.
Source: Wirecutter, CNN Underscored - T-adapter leaks; pressure too strong for some
Amazon's review summary says several customers report leaks at the T adapter, and that some find the water pressure too strong. CNN found its stream only okay and nowhere near as comfortable as the Tushy Classic 3.0's.
What owners love
- Easy install, no outlet, keep your seat
Wirecutter says you just remove the seat, place the SlimEdge and put the seat back on; no outlet is needed. Amazon shoppers also find it easy to install.
- Simple one-dial control
Wirecutter says turning the dial one way starts the rear wash and the other way the front wash, and that it does the cleaning work just fine. Amazon shoppers say it leaves them feeling clean.
- Looks better than most cold-water models
Wirecutter says most cold-water models look like they belong in a hospital, while the SlimEdge has a rubbery grip and nicer curves. Amazon shoppers also like its appearance.
