Do I Need a Plumber to Install My Bathroom Vanity?

Do I Need a Plumber to Install My Bathroom Vanity?

Joe Bargh |

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 Whether you’re renovating or simply replacing an outdated unit, one of the most common questions we hear is: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.
