Finding a good bathroom fitter isn't always straightforward. The bathroom trade - like most trades - has its share of cowboys, and a bad installation is expensive and stressful to put right.

Bathrooms don't give up overnight. They deteriorate slowly, and it's easy to get used to the dripping tap, the grubby grout, or the shower that takes three minutes to warm up.
