We deliver complete bathrooms, ensuites, wetrooms and walk-in showers through one directly-managed team — no subcontracting the job out to strangers you've never met. Every project starts with a free home survey and a fixed price agreed in writing before any work begins, so there are no surprise costs once we're on site.

We tile bathrooms and kitchens alike, whether you supply your own tiles or we do, with exact quantities specified up front. We're Constructionline Gold and SSIP accredited, and every job comes with a 24-month workmanship warranty. Our last four bathroom renovations ranged from £11,500 to £16,000 and took two to four weeks on site — real figures from real completed jobs, not estimates.
