We moved into a rented house 4 months ago. The landlords said they would fit a shower for us (one of the reasons we took the house). They didnt. So we've spent the last 4 months trying to resolve it. Eventually they have agreed to put up £200 towards the installation of the shower. We have had to purchase a shower out of our own money. It has really annoyed me that they have backed out of their obligations and that its costing us more to improve their home. So at the end of our tenancy would it be really cheeky to ask if they would like to buy the shower from us?
