BenBathroom industry for 20 years · 700+ and counting bathrooms I’ve had a hand in

My aim is to help you navigate your renovation with confidence and hire the right people for the job. I don’t quote the building work and I don’t manage your build.

I’ve spent years managing bathroom trade teams — verifying standards, securing certifications, and ensuring seamless handoffs between trades, where costly mistakes usually happen. Because I backed every project with my own personal warranty, I know firsthand that a price estimate won’t tell you who is genuinely qualified.

Knowing which questions separate true professionals from the rest comes from years on site. That’s the clarity and peace of mind I bring to your project.
