The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the TOTO WASHLET C5 is the benchmark premium electric seat, and r/bidets sentiment runs strongly positive, with one owner calling it 'nothing short of a miracle worker' and praising TOTO's reliability and build quality. Its PREMIST and EWATER+ wand-cleaning features, warm water, adjustable pressure, and wireless remote are the headline draws, and a community comparison thread frames the Costco-style WASHLET and C5 as delivering 'the core TOTO experience at a fraction of the cost' of higher-end models. We surface the disagreement honestly: a prominent r/bidets review titled around avoiding it 'like the plague' exists, and a recurring, specific complaint, echoed even by satisfied owners, is that hot water runs only about 40-55 seconds before going cool, since the C5 uses a reservoir rather than fully tankless heating.
What reviewers liked
- TOTO reliability and build quality repeatedly praised in r/bidets
- Warm water, adjustable pressure, PREMIST bowl misting, and wireless remote
- 4,100+ verified reviews at 4.4 plus strong community endorsement
Where it falls short
- Reviewers report warm water lasts only ~40-55 seconds (reservoir-based, not endless)
- Community reviewers warn the lid isn't rated to sit on due to fragile electronics
- At least one vocal r/bidets review strongly advises against it; premium price

An r/AllAboutToto poster also dislikes that the lid isn't rated to sit on due to fragile electronics.
The trust-weighted takeaway: this is a well-built, widely satisfying premium seat whose main limitations, finite warm-water duration and a non-sittable lid, are consistent enough across sources to take seriously before buying.

I paid about 450 for this toilet seat and man is it the worst seat I've ever sat on. Here's a list of reasons you should avoid it like the plague.
I own the C5.. it is nothing short of a miracle worker. The only downside I see is the 40 to 55 seconds of hot water.
