Shower faults vary from a quick cartridge replacement (£30 DIY) to a full shower system replacement (£500+). The good news is that most shower faults are mechanical and very fixable. Whether you've got a dripping shower head, a lukewarm electric shower, or a walk-in that's lost pressure, the repair is usually more straightforward — and cheaper — than you'd expect.

Electric showers typically last 6–10 years. Thermostatic bar showers and mixer showers last 8–15 years. The cartridge (the mixing valve) is usually the first thing to wear out, but it's a straightforward replacement. Power showers with pumps sit at the shorter end of the lifespan range.
Electric showers under 6 years old are almost always worth repairing — even a full unit replacement is only £250–£450 fitted. For thermostatic mixer showers, cartridge replacement (£80–£160) is a common mid-life repair that adds many more years. Shower pumps (£150–£300) are worth replacing if the rest of the system is in good order.

The three main types of shower in UK homes are electric, mixer, and power showers — and each has different repair implications. Electric showers (brands like Mira, Triton, and Aqualisa) heat water on demand and are the most common in the UK. They're relatively cheap to replace (£150–£350 fitted) but internal element and PCB failures can be costly to repair. Mixer showers blend hot and cold water from your existing supply and tend to be more reliable, with thermostatic cartridge replacement being the most common repair (£80–£150). Power showers use an integrated pump to boost water pressure and are ideal for homes with gravity-fed systems, but pump failures can cost £100–£200 to fix. Knowing your shower type helps you assess whether a repair quote is reasonable.
Showers are generally cheaper to run than baths, but running costs vary significantly by type. An electric shower at 8.5 kW costs roughly 30–40p per 8-minute shower at current UK electricity rates. Mixer showers draw from your hot water cylinder, so their cost depends on how you heat your water — gas is typically cheaper than electricity. Power showers use the most water and energy due to their high flow rates. If you're replacing a shower, consider a model with eco settings or flow restrictors — these can cut water usage by up to 40% without noticeably affecting pressure. Water meters, now common across much of England and Wales, make these savings even more significant for household bills.
Usually yes — most shower faults are cartridge or pump issues that are straightforward to fix. Cartridge replacements cost £80–£160. Even a full electric shower unit replacement is only £250–£450 fitted, making repair nearly always worth considering.
Shower repairs in the UK typically cost £80–£300. Electric shower cartridges run £80–£150. Shower pump replacements cost £150–£300. Most plumbers can diagnose and fix common shower faults in a single visit.
Electric showers last 6–10 years. Thermostatic mixer showers last 8–15 years. Regular descaling in hard water areas significantly extends the life of cartridges and showerheads.
Low shower pressure is usually a blocked showerhead (descale it first), a failing shower pump, or low mains pressure. Descaling the showerhead with white vinegar is free and fixes the problem in many cases.
