YOUR PERSONAL SANCTUARY

Bespoke Bathroom Renovations Designed for Relaxation.

A bathroom should be more than a functional space; it should be a private retreat. At BAS, we specialize in luxury bathroom renovations that combine spa-like aesthetics with uncompromising technical standards. From reconfiguring your floor plan to install modern wet-room zones and high-pressure rainfall showers to the precise tiling of intricate mosaics, we handle every detail with the care required for a perfect, long-lasting finish.

Complete bathroom strip-out and structural reconfiguration.
Professional plumbing upgrades for modern, high-pressure systems.
Specialist moisture-management and waterproof tanking systems.
Precision tiling, lighting, and bespoke vanity installation.

We manage the complex hidden elements of a bathroom renovation, such as structural floor reinforcing for heavy stone tiles, advanced waterproofing (“tanking”) to prevent future leaks, and smart ventilation to ensure your space remains fresh. We treat the technical plumbing and electrical infrastructure as the foundation for the luxury finishes that follow, ensuring your new bathroom is as reliable as it is stunning.

THE SANCTUARY SPECIALISTS

Engineering Longevity Into Every Bathroom.

Bathroom renovations are arguably the most demanding projects in a home due to the constant presence of water. BAS Building applies rigorous moisture-protection standards and expert plumbing integration to every project, ensuring your investment remains pristine and watertight for years to come.

Wet Room Tech

Expertise in creating seamless, floor-level walk-in shower areas with perfectly graded drainage.

Tanking Systems

We use industrial-grade tanking (waterproofing) membranes behind all wet areas to guarantee 100% moisture protection.

Precision Tiling

Master-level laying of large-format porcelain, intricate mosaics, or natural stone with flawless grout lines.

Ambient Lighting

Integration of LED mirrors, recessed alcove lighting, and dimmable zones to create a true spa atmosphere.

A bathroom is the ultimate test of a builder’s precision. It’s not just about the beautiful tiles you see; it’s about the invisible waterproofing and the quality of the plumbing hidden behind the walls that makes a bathroom last.

CLIENT TESTIMONIALS

Delivering Excellence
Through a Dedicated Team.

“ The team at BAS Building transformed our dated kitchen into a stunning open-plan living space. Their attention to detail, especially with the structural steelwork and glazing, was second to none. They were energetic, professional, and kept the site incredibly clean throughout the entire build. We couldn't be happier with our new home. ”

James Sterling

Homeowner, Surrey

“ I hired BAS for a complex loft conversion that required a lot of custom carpentry. Robert and his team were a breath of fresh air; they provided creative solutions to structural issues and finished the woodwork to a cabinet-maker’s standard. It’s rare to find a building company that cares this much about the fine details. ”

Sarah Jenkins

Property Developer

“ Building a house is stressful, but BAS Building made it feel manageable. Their project management is top-tier—they coordinated every trade perfectly and stayed exactly on budget. Their 'energetic team' isn't just a slogan; they truly worked with passion to get us into our home ahead of schedule. Highly recommended! ”
