And so it begins ... the refurbishment of my downstairs bathroom to be a shower room.   The self-builder who added an upstairs and extension to the bungalow got a few things wrong, and one of them was that he put a bathroom downstairs, and a shower room upstairs; exactly the wrounf way round for when a frail relative or disabled visitor needs to have downstairs facilities.   So this summer both bathrooms are being overhauled - starting with the downstairs one this week.
