I am currently renovating a bathroom. all old stuff ( bath, sink, toilets, flooring, tiles on walls etc removed) new stuff installed this time with a power shower which will mean new wiring in the walls for the power. a good friend of mine who is in the business is doing it. he is also supplying a new door/architrave and ceiling, and also is going to change the light fittings around and also the light switch to the hall.I am supplying the bathroom items(shower/sink etc) and the tiles.his costs are €4,500. There is a another builder locally who specialises in bathrooms . his guarantee is that he starts on a monday and the bathroom is turnkey on a friday. I asked him over the phone to give me a ball park quote and he replied that ball park for a new bathroom was €8,000. €3000 for fittings, €1000 for tiles/floors and his labour €4000. thats without him coming out and actually assessing the actual site ( I didn't mention the new door/ceiling and changing the light fittings around) my friend is €500 more expensive which leads me to believe that the other 'specialist' is not over the top with his costs either. Know this doesn't answer the question but it sort of confirms that the 2nd tradesman, whom I dont know is not ripping off customers. (for what its worth 4 weeks waiting on my friend/6 weeks if I had opted for the other builder.) my actual bill for units etc was €3200 which again is pretty close to what the 2nd builder gave over the phone as his ball park figure. I'd hazzard a guess that the profit margin is pretty consistant on small work like this. dont know what it is though.
