Yes, as someone who had a psychotic builder I ended up having to call the police on, I do dwell on the sweet, patient builders who seem to be a staple of these shows.
Aoibheann MacNamara, who is admirable, but also a rather difficult individual to deal with (the Galway Ard Bia owner whose house in the Burren was on last week's episode), must have been a massive headache for her builder, when she kept delaying key decisions and deciding at the last minute she wanted a kitchen mezzanine, but her builder seemed like an unfledged angel!
Yes, I can honestly say that I have never given my shower tray a second thought, fond though I am of my bathroom, and fussy though I am about the view from my bath!
