Thinking of upgrading your bathroom vanity? You’re not alone. Whether you’re renovating or simply replacing an outdated unit, one of the most common questions we hear is:
“Do I need a plumber to install my bathroom vanity?”
Let’s break it down so you can decide if this is a DIY job—or one for the pros.
✅ What Does Installing a Vanity Involve?
Installing a bathroom vanity can be more involved than it first appears. It typically includes:
-
Assembling or positioning the unit
-
Securing it to the wall
-
Connecting water supply lines
-
Fitting the basin and tap
-
Connecting the waste trap and drainage
If your new vanity comes pre-assembled with an integrated basin, things are simpler. But if it’s a wall-hung unit, includes custom tap holes, or requires moving pipework—things get more technical.
🔧 When You Can DIY
You might be able to handle it yourself if:
-
You’re replacing a like-for-like unit with identical plumbing positions
-
No new holes need to be drilled in tiles or walls
-
You’re comfortable turning off the water supply and working with basic plumbing tools
-
You're not touching anything behind the wall (e.g., concealed pipes)
🛒 Tip: Many of our freestanding vanities come pre-drilled and ready to connect—ideal for simple swaps.
🧰 When You Need a Plumber
Bring in a professional if:
-
You’re installing a wall-hung vanity (must be properly anchored and levelled)
-
You’re moving or altering any plumbing
-
You’re installing new pipework or a concealed tap
-
You’re unsure about isolating the water supply
-
You want peace of mind with warranties and insurance
A qualified plumber will ensure everything is watertight, compliant with UK regulations, and built to last.
🚿 What About Electrics?
Some vanities come with integrated LED mirrors, demister pads, or USB charging ports. These will require a Part P-registered electrician to safely connect to the mains.

💡 Our Advice
For most installations, we recommend at least a consultation with a plumber, especially for wall-mounted units or anything involving pipe rerouting. A quick install can easily turn costly if leaks or water damage occur down the line.
If you're simply swapping like-for-like with exposed pipework and you're confident with a spanner—you might just manage it yourself.
