Access and Mobility Bathrooms were outstanding from start to finish. What began as a tricky idea to create a bedroom extension and utility area from awkward old Victorian rooms (with damp and every possible challenge) has turned into an amazing space that exceeded all expectations. Lee kept in regular contact, gave clear timescales, and offered great suggestions whenever we ran into obstacles. Every member of the team was polite, professional, tidy, and worked to an exceptionally high standard. Their attention to detail, cleanliness, and “can-do” attitude made the whole experience stress-free. The finished room for my son and the fabulous utility and toilet are beyond what I hoped for. I’d recommend this company without hesitation!
