Not quite the same thing but in 2021 my downstairs wet room needed work because I put my foot through the floor of the shower area
The fix was to replace the shower area with a base board and tile
I got three quote, one from a Dublin plumbing company of around €2k and was told I wouldn't get better by the sales rep
The second was a builder recommended to us by my BIL, came in at €3k but felt it was really a pfo quote
The third was a neighbours recommendation that came in at €900 all in, which is what we went for
So yeah, as Pinoy adventure suggested get at least 3 quotes but also try your neighbours as they might know somebody in the trade
