In Short
Bidets, shower toilets and bidet seats come in seven common types for cleaning yourself with water after the toilet. They differ in whether they need power, where the warm water comes from and how much of the bathroom changes. Most of them fit a completely normal toilet.
What We've Been Sold as Normal
A bidet means a French basin. A shower toilet means a bathroom designed by an architect. Supposedly there's nothing in between, so paper it is.
The Honest Explanation
| Type | Power | Warm water | Bathroom changes |
|---|
| Shower toilet as a complete toilet | yes | heated in the unit | new ceramics, professional installer |
| Electric bidet seat | outlet | heated in the unit | replaces the toilet seat |
| Bidet seat, cold water only | no | none | replaces the toilet seat |
| Bidet seat, warm and cold mixed | no | from the hot water line | replaces the toilet seat |
| Attachment under the seat | usually no | depends on the model | sits under your existing seat |
| Handheld sprayer at the toilet | no | only with a mixer | connection at the wall |
| Freestanding bidet | no | via the faucet | its own basin and drain |
| Portable butt shower | no | as warm as you fill it | nothing |
Where the cold water comes from depends on the toilet. With a visible cistern, it comes from the angle valve next to it. With a cistern in the wall, it comes from the angle valve under the sink.
What You Often Hear – and What's True
“Warm water only comes with power.”
No. A bidet seat that mixes warm and cold takes it from the water line, for example our New Standard.
“Shower toilet means new toilet.”
Only with the complete toilet. An electric bidet seat only replaces the seat, for example our Deluxe.
“The expensive type cleans better.”
Cleaning is always done with water. The price pays for features and installation.
Putting It in Context
If you know whether an outlet and a hot water line are within reach, you've already made half the choice.
