My shower mixing valve has been dripping for weeks now—maybe 10-15 drops a minute. It's a 2005 semi-detached house. I've watched some YouTube videos and it looks straightforward, but I'm worried about water damage or messing up the plumbing. Is this a job I can DIY, or will I end up spending more fixing my mistakes?
A dripping shower valve should not be ignored—even small leaks waste water and can lead to mold or structural damage over time. Replacing a mixing valve yourself is technically possible if you're confident with tools and can isolate the water supply, but there are real risks: incorrect installation can cause leaks behind the wall, water pressure problems, or voiding your home warranty. Professional plumbers in Eindhoven typically charge €150–€300 for a straightforward valve replacement (including labor and callout), depending on valve type and accessibility. DIY parts cost €30–€80, but if you damage fittings or need to call a pro afterward, you'll spend more overall. Unless you have solid plumbing experience, the €150–€200 you save rarely justifies the risk.
