Long story. We needed a new shower door for our loft conversion cubicle. The width for the door is a non-standard size and we couldn't get it online, so we ordered from the local plumbers merchant who supplied some of the other fixtures for our bathroom. My fitter spoke to the merchant and they agreed the door, a photo of which was sent to me. I placed the order and paid.
The door arrived and the fitter realised, after opening it, that it's too tall (2000mm for an 1850mm gap). I called the plumbers merchant who won't take it back because it's been opened. So we are stuck with a £450 door we can't use.
I don't know what my rights are here and am completely willing to accept that I've been stupid in relying on the merchant and the fitter to get the size right. I wasn't involved in any conversations about the dimensions, and was not told at any point that I was not entitled to a refund if the door had been opened. Is there any hope?!
