Smart toilets and bidet seats have moved from an Asian luxury to a growing presence in the UK bathroom market. Models from Geberit, TOTO, and a growing range of specialist suppliers now offer heated seats, water washing, warm air drying, and automatic lid operation. The question for UK homeowners is whether these features justify the cost — and what installation involves.

The options broadly fall into three categories: bidet seats (fitted to an existing toilet pan, adding a water wash function), bidet shower attachments (a simple cold water spray attachment, the cheapest entry point), and integrated smart toilets (a complete pan and seat unit with full electronic features). Integrated units offer the most seamless look but require the whole toilet to be replaced.
What electrical connection is needed
Any electronic bidet seat or smart toilet requires a switched fused spur (a dedicated electrical connection point) near the toilet. This is a notifiable electrical work in England under Part P of the Building Regulations when in a bathroom — it must be done by a registered electrician or notified to building control. The socket must be positioned so that no cable can reach into the bath or shower zone.
The hygienic benefits of bidet washing are well-documented, and the environmental case — reducing toilet paper consumption — is genuine. Smart toilets are not a gimmick; they are a different approach to personal hygiene that has been mainstream in Japan for decades.

Costs and value
Entry-level bidet seats (heated seat, cold wash function) start from around £150. Mid-range models (heated seat, warm wash, adjustable pressure and temperature) run £300-£800. Premium smart toilet units from Geberit or TOTO can reach £2,000-£5,000+. For the majority of homeowners considering this for the first time, a mid-range bidet seat fitted to an existing toilet is a low-risk, reversible way to try the experience.
