Help & advice
Last updated: May 22, 2026
When starting a bathroom renovation project, the decision of whether to do some or all of the work yourself or to hire a professional hinges on various factors:
Bathroom renovation projects can involve many individual trades, including builders, plumbers, electricians, plasterers, tilers, carpenters and decorators. If you use a general builder or contractor, they can often manage the whole project, including hiring and coordinating all the required trades.
Scenarios where hiring professionals becomes crucial include:
If you're confident your bathroom renovation project doesn't fall into one of these scenarios and are still keen to do the work yourself, you might want to avoid fixtures and fittings that require more specialist knowledge to fit, like wall–hung sanitaryware!
You may also consider purchasing all your fixtures and fittings from a single bathroom specialist that provides an installation service.
Finally, you'll need to do your research and ensure you are up to date on what you will require certification for, e.g. any new windows and all the electrics including new lights, sockets and electric radiators or underfloor heating.

Frequently asked questions
Can you renovate a bathroom yourself?
You can do parts of a bathroom renovation yourself if you have the skills, time and confidence. Decorating, some demolition and simpler fitting work may be suitable for DIY, but plumbing, electrics, waterproofing and structural changes usually need professional input.
When should you hire trades for a bathroom renovation?
You should hire trades if the work involves electrics, plumbing changes, structural work, wet room installation, building control approval or anything that needs certification. These are the areas where mistakes can become expensive or unsafe.
What bathroom work should not be DIY?
You should be very careful with DIY electrics, structural changes, wet room waterproofing, drainage changes and wall-hung sanitaryware. These all need proper installation and may require certification, inspection or specialist experience.
Do you need a builder or separate trades for a bathroom renovation?
You can either hire separate trades yourself or use a general builder or contractor to manage the project. A contractor can coordinate plumbers, electricians, tilers and decorators, which is usually easier if the work is more complex.
Can I install a bathroom in a room that was not previously a bathroom?
You can, but it is usually not a simple DIY job. Creating a new bathroom from scratch often involves drainage, ventilation, electrics, plumbing and building control approval, so professional help is normally needed.
Do bathroom renovations need building control approval?
Some bathroom renovations need building control approval, especially if you are creating a new bathroom, making structural changes, changing drainage, adding new electrics or altering ventilation. Simple like-for-like replacements may not need approval.
Can I do my own bathroom tiling?
You can tile a bathroom yourself if you are confident and have prepared properly. The risk is higher in wet areas, especially showers and wet rooms, where poor preparation or waterproofing can lead to leaks later.
Is it cheaper to renovate a bathroom yourself?
DIY can reduce labour costs, but it can become more expensive if mistakes cause delays, leaks or rework. It is usually safest to DIY simpler tasks and use professionals for plumbing, electrics, waterproofing and structural work.

What needs to be waterproofed in a bathroom?
Tiling a bathroom does not make it waterproof. The waterproofing sits behind the visible finish and protects the structure of your home.
