What Affects the Cost of a Wet Room?
Several factors influence the final price of a wet room installation:
✅ 1. Size and Layout of the Bathroom
Larger rooms require more materials and labour. Compact spaces may reduce cost — but if layout changes or plumbing repositioning are needed, this can increase complexity.
✅ 2. Waterproofing and Drainage
A fully waterproofed membrane system is essential for a wet room. High-quality drainage and floor grading (to prevent pooling) are also part of the cost.
✅ 3. Flooring and Wall Finishes
Options include:
Slip-resistant vinyl (budget-friendly)
Porcelain or natural stone tiles (premium)
Wet wall panels (low maintenance, mid-range cost)
Each has its pros and price points. We can advise during your home survey.
✅ 4. Accessibility Features
If you’re installing a wet room for an elderly or disabled person, you may need:
Grab rails
Shower seating
Extra-wide access or carer space
Anti-scald thermostatic controls
Half-height shower screens
These improve safety and usability but can slightly increase the total cost.

✅ 5. Plumbing and Electrical Work
Upgrading the water system, adding an electric shower, or adjusting lighting and ventilation may add to the cost — especially in older properties.
✅ 6. Labour and Installation Quality
Professional installation is crucial for wet rooms. Poor waterproofing or incorrect drainage leads to leaks and long-term damage. Always choose an experienced wet room specialist (like Showering Easy) for peace of mind.

Can I Get Help with the Cost?
If you’re installing a wet room for mobility or health reasons, you may be eligible for a Disabled Facilities Grant (DFG) from your local council. These can cover all or part of the installation cost.
