Most people choose a faucet based on how it looks and what it costs. Professional plumbers choose differently — they have installed hundreds of taps across dozens of brands, seen what fails and what lasts, and developed strong preferences based on real-world evidence rather than showroom appeal.
We spoke to several UK plumbing professionals to understand their selection criteria. Their answers consistently revealed priorities that most homeowners never consider.
1. Cartridge Availability
“The first thing I check before recommending a faucet is whether the cartridge is available in five or ten years. Some brands — particularly direct-import brands from China with UK branding — are discontinued and replacement parts disappear within three years. When that happens, the whole tap needs replacing. I only specify brands where I know cartridges will be available long-term: Grohe, Hansgrohe, Ideal Standard, Bristan, Vado.”
2. Installation Accessibility
“I care a lot about how easy a tap is to install and service. Some designs look beautiful but require specialist tools to fit, or have components that are genuinely difficult to access for repairs. Tap connectors should be reachable with standard tools. The hot and cold inlets should be clearly marked and in sensible positions. Some premium designer taps are a nightmare to work on — beautiful objects, terrible engineering from an installation perspective.”
3. Valve Quality Above All
“I always ask what valve is inside. A brass body with a poor quality ceramic disc is worse than a good ceramic disc in a decent body. Sedal and Kerox are the two ceramic disc manufacturers whose cartridges I trust — and most quality European brands use one of them. I can usually tell the quality of the valve from how the lever action feels in the showroom. A good ceramic disc has a specific damped, smooth quality that a cheap one cannot replicate.”
4. Flow Rate Consistency
“I check the stated minimum operating pressure. Some taps require a minimum of 1 bar to function properly — in low-pressure gravity-fed systems, that means the tap will barely perform. I always match the tap specification to the system. Combi boiler systems can handle higher minimum pressure requirements; gravity-fed systems need low-pressure-rated taps. This is one of the most common installation errors I see when I take over after another tradesperson.”
5. Warranty and Brand Support
“A five-year guarantee means nothing if the brand is uncontactable when you try to use it. I look at actual brand track record — Grohe, Hansgrohe, and Ideal Standard all have genuine, functioning warranty support that I have used successfully. Some smaller brands have generous-sounding warranties that are practically impossible to redeem. The warranty is only as good as the company behind it.”
The Professional Short List
When asked which brands plumbers actually install in their own homes, the answers were remarkably consistent: Grohe for kitchen, Hansgrohe for bathroom, Ideal Standard for family bathrooms, Crosswater for design-forward bathrooms, and Vado for budget-conscious projects. The brands that appear in showrooms and marketing rarely appear on this short list — professional selection is driven by installation reliability and long-term performance, not aesthetics.
