Challenges & Solutions

Challenge 1: Uneven Walls After Strip-Out

Older bathrooms often reveal surface defects once tiles are removed.

Solution:
The team applied specialist bonding coats, reinforcement mesh, and levelling layers before micro-cement application to achieve perfect wall flatness and long-term durability.

Challenge 2: Limited Space for Pipework Routing

The property had an older plumbing layout with minimal chase depth.

Solution:
We redesigned the pipework route, utilised compact components, and installed a custom-built bath subframe to house pipes safely without compromising aesthetics.

Challenge 3: Heavy Large-Format Tiles on Weak Stud Walls

The walls required additional strength to support oversized tiles.

Solution:
We reinforced the structure with moisture-resistant boards and additional stud support before tiling, ensuring a solid and safe installation.

Results

The new bathroom delivers a minimalist, modern, and seamless aesthetic, combining textured micro-cement walls with luxury stone-effect flooring. The improved layout, upgraded plumbing, and full waterproofing system provide long-term functionality and comfort.

This renovation increased both the modern appeal and property value, creating a bathroom built to last for many years ahead.
