Are bidets legal in the UK?

 A recent Reddit thread sparked debate when a user claimed their plumber warned bidets were illegal in the UK. While the assertion has raised eyebrows, the reality is more nuanced. Here’s a breakdown of the legal status, regulations, and cultural factors shaping bidet use in Britain.

Legality: No Blanket Ban, but Strict Compliance Required

Bidets are not outright illegal in the UK. However, their installation must adhere to stringent plumbing and safety regulations. The primary framework governing water fittings is the Water Supply (Water Fittings) Regulations 1999, which aims to prevent contamination and ensure public health. Key requirements include:

1. WRAS Approval: Products must carry certification from the Water Regulations Advisory Scheme (WRAS), confirming they meet UK safety and efficiency standards.

2. Backflow Prevention: Bidets pose a high risk of cross-contamination (classified as Fluid Category 5), necessitating devices like air gaps or double-check valves to prevent wastewater from flowing back into the mains supply.

3. Electrical Compliance: Electric bidet seats or smart toilets require a dedicated, RCD-protected power supply installed by a certified electrician, adhering to Part P of the Building Regulations (no sockets within 3 meters of water sources).  

Cultural Misconceptions and Market Trends

The idea of bidets being "sinful" or associated with unsavory practices dates back to WWII, when Allied soldiers linked them to brothels. This stigma persists, though modern models prioritize hygiene and eco-friendliness. Today, bidets are gaining traction due to:

Environmental Benefits: Reducing toilet paper use by up to 75%.

Health Advantages: Lowering risks of urinary tract infections and hemorrhoids.

Space Efficiency: Options like bidet seats or handheld sprayers (shattafs) fit into compact bathrooms.

Types of Bidets and Installation Considerations

UK consumers can choose from:

Standalone Bidets: Require dedicated space and plumbing.

Bidet Seats: Replace existing toilet seats, with electric models offering heated features.

Handheld Sprayers: Affordable and flexible but demand manual operation.

Smart Toilets: Integrated systems with bidet functions, popular in luxury renovations. Installers must ensure compatibility with toilet shapes and water pressure, while landlords and renters should check tenancy agreements before modifications.

Expert Advice

"Bidets are legal if installed correctly," notes plumbing expert Louis from Bathroom Supplies Online. "Always verify WRAS approval and consult professionals for electrical work." The UK’s shift toward sustainability and hygiene suggests bidets may become more common, provided regulations are respected. In summary, bidets are not illegal in the UK, but compliance with safety standards is non-negotiable. As attitudes evolve, these devices could soon become a fixture in British bathrooms—provided they meet the country’s strict regulatory framework.
