Tackling tricky problems are all in a days work. When a newly-wed customer wanted a new shower in their home, they ran into a problem. A old fashioned shower needed replacing. But there was no replacement to fit.
The tiles could not be removed as the budget did not allow it. A little head scratching later and key-hole surgery found the solution. It is nice to report a success. They did not lose control of the budget, and got the shower they wanted.
