Challenges & Solutions
Challenge 1 – Limited space for walk-in configuration
The room footprint made it difficult to include a full wet room layout.
Solution:
We redesigned the layout based on precise measurements and introduced a slimline tray with minimal threshold, ensuring both accessibility and usability.
Challenge 2 – Uneven walls and moisture damage
The original structure showed signs of moisture infiltration and poor previous tiling.
Solution:
All walls were corrected, re-boarded where needed, and fully tanked to guarantee long-term waterproofing.
Challenge 3 – Achieving perfect alignment with herringbone tiles
The textured herringbone pattern required precision to look clean and symmetrical.
Solution:
Each tile was individually calibrated with laser alignment to maintain a consistent rhythm across the entire wall.
Results
- Sleek, modern wet room with strong contrast and premium materials
- Fully waterproofed environment built for durability
- Dark herringbone feature wall becomes an architectural focal point
- Increased comfort thanks to rainfall shower and open walk-in layout
- Practical and visually striking upgrade to the property
