I’ve paid good money for a bathroom installation. This follows on from having an en-suite installed last year. Both involved replacing existing radiators with flexi pipe behind them with towel rails. When my towel rail was fitted in the en suite the plumber fitted with two very short pieces of pipe from directly behind the towel rail valves - a really nice fit. But my bathroom’s plumber has fitted like the first picture here with a large hole and lots of pipe visible - which I think goes against the point of a towel rail which you can see through. Am I in my rights to have expected a neater fit and get him to change? He says I should have specified at quote stage but it’s not something I specified to my en suite plumber. My expectation from looking at other houses and pics online is that the towel rail should be fitted like the second pic.
