A bath shower mixer tap looks like a simple swap, but whether it works depends on pressure and flow, not the boiler badge. This guide explains the 0.2 bar minimum listed for the Aqualisa Central, Uptown and Downtown taps, how much head a loft tank really gives you, and why a combi is limited by heat output rather than the tap. It also covers the hose rule that keeps a handset clear of bath water, with prices and stock checked on 4 November 2026.

The same shower can feel superb in one house and weak in the next, and the water system is almost always the reason. This guide shows how to tell whether you have a gravity-fed, combi or unvented system, then which shower types suit each: power, gravity-pumped smart, mixer, high-pressure smart or electric. It includes a worked four-bathroom cost comparison and Aqualisa picks with prices and stock checked on 20 October 2026.

In a care home, a shower that surges hot when the cold supply drops can seriously scald a resident who cannot move away or feel the heat in time.

BS 7671 Amendment 4 isn't just an electrician's problem, it's a landlord cost. We break down the two dates that actually matter, what AFDD protection adds to a rewire quote, and exactly what to ask your electrician before booking work. Covers the HMO licensing angle too.

How many bathrooms does your HMO actually need? We break down BS 6465 sanitary provision tables, what counts as a compliant bathroom for licensing, and which fittings from Geberit, Ideal Standard, Grohe and Aqualisa make refurb day easier.
