DIY Bathroom Fitting: A Friendly Guide for Anyone “Giving It a Go”

Thinking of fitting your own bathroom? You’re not alone. Plenty of homeowners in Norwich and Norfolk take on their own bathroom projects — sometimes to save money, sometimes for the satisfaction, and sometimes because they’ve watched a few YouTube videos and thought, “How hard can it be?”

The truth is: **DIY bathrooms can be done well**, but only if you know where you can safely save money — and where cutting corners will cost you far more later. And here’s the important part:

Where DIY’ers Often Go Wrong

We see the same issues again and again — and they’re all avoidable:

• Using the wrong pan connector (or forcing one that doesn’t fit)
• Choosing a toilet that’s “cheap” instead of “failsafe”
• Sealing a shower cubicle on the inside instead of the outside
• Installing items in the wrong order (a classic DIY mistake)
• Not tanking or waterproofing properly before tiling
• Cutting corners that accidentally invalidate warranties
• Using silicone where a mechanical seal is required
• Not allowing for expansion on wall panels or flooring

None of these make you a bad DIY’er — they just mean you haven’t done this 200 times before. We have.

Where You Can Save Money (and Where You Shouldn’t)

💸 Places DIY’ers CAN safely save money

• Removing old tiles and fixtures yourself
• Painting and decorating
• Building simple stud walls or boxing
• Fitting wall panels (Wetwall, Nuance, PVC) if the walls are prepared correctly
• Installing furniture once plumbing is in the right place

⛔ Places you should NOT cut corners

• Waterproofing (tanking) the shower area
• Levelling floors before trays or tiles go down
• Choosing the toilet — cheap ones cause endless issues
• Shower tray installation and waste alignment
• Sealing — especially around trays, cubicles, and baths
• Anything involving pressure plumbing or waste gradients

The Correct Order to Install a Bathroom

Getting the order wrong is one of the biggest DIY pitfalls. Here’s the safe, industry‑standard sequence:

1. Strip out old bathroom
2. First fix plumbing (before walls are closed)
3. First fix electrics
4. Boarding, levelling, and waterproofing
5. Fit shower tray or wetroom former
6. Tile or install wall panels
7. Fit flooring
8. Install toilet, basin, furniture, and brassware
9. Seal everything correctly (outside of cubicles, not inside)
10. Final checks and commissioning

Warranties: How DIY’ers Accidentally Void Them

Manufacturers are strict. The most common reasons warranties get voided:

• Incorrect installation of trays or pans
• Using non‑approved sealants or adhesives
• Not waterproofing before tiling
• Incorrect spacing or support under baths
• Cutting panels or boards incorrectly
• Not following the installation sequence
