Did a bathroom in my old house, run pipes under floor, all soldered joints etc, It's still going strong 20 years later
This isn't my property so I'll have to grin and bear it for the time being, I know what needs doing but all they talk about is budgets.
I had to tidy up plastering in my hall after they did a crap job, also had to remove woodwork and start again with quality timber, looks so much better.
I have to sign a disclaimer because I kept my old shower and need to change the radiator as the one they fitted is a small towel rail and although looking nice it doesn't throw any heat out and its a bigish bathroom.
I didn't tell em that I had re routed some of the plumbing before they started so as it would be neater and more efficient
