Day-by-Day Breakdown of a Wet Room Installation

Here’s what to expect at each stage of your wet room transformation:


Day 1: Removal of Old Fixtures & Prep

  • Strip out old bath, shower, toilet, tiles or flooring

  • Remove any damaged or waterlogged materials

  • Check plumbing and drainage systems

  • Prepare subfloor and walls for waterproofing

🛠️ Tip: If you’re replacing a bath with a wet room, you can usually use the same plumbing connections, which can save time and money.


Day 2–3: Waterproofing & Drainage Installation

  • Fit wet room floor former or tray base

  • Install linear drain or waste outlet

  • Apply tanking system to floor and lower walls (liquid membrane or waterproof sheet)

  • Ensure appropriate fall for water to drain efficiently

Proper waterproofing is absolutely essential in a wet room — this is not a DIY job. We only use high-quality materials that meet British standards and are suitable for long-term moisture exposure.


Day 4–5: Flooring & Wall Finishes

  • Lay non-slip safety flooring or porcelain tiles

  • Install wet wall panels (optional alternative to tiling)

  • Seal all joints and edges

  • Allow appropriate drying time (especially for tiling grout or adhesive)

Day 6: Fit Fixtures & Accessories

  • Refit toilet, basin, and pipework

  • Install shower screen, if applicable

  • Add grab rails, shower seats, thermostatic controls

  • Connect extractor fan or improve ventilation if needed

If you’re adapting the bathroom for a disabled or elderly family member, we’ll make sure all safety features are installed exactly to your needs.

Day 7: Final Checks & Handover

  • Full water test to check for leaks or drainage issues

  • Clean and polish all surfaces

  • Demonstrate how to use any new controls or features

  • Handover with warranty and care instructions

Most homeowners are ready to use their new wet room the next day!


Can It Take Longer?

Sometimes, installation may take slightly longer if:

  • Structural issues are uncovered during preparation

  • Your existing bathroom needs extensive plumbing or rewiring

  • You’ve chosen bespoke features or luxury finishes

  • The property is in a listed building or unusual layout

We always inform customers ahead of time if anything unexpected might delay the project. Our aim is to keep disruption minimal and finish on time.


Do I Need to Move Out During Installation?

No — in most cases, you can remain at home. However:

  • You may be without your main bathroom for several days

  • We recommend alternative arrangements for vulnerable individuals (e.g., elderly relatives)

  • For larger projects, we can arrange for temporary facilities if needed

We work cleanly and respectfully, always tidying up at the end of each day.
