How much does it cost to renovate furniture and water pipes and circuits for one meter?

That's not a good calculation! It depends on what brand of stuff is used!

It's hard to say, my home is 320 square meters, water transformation, I completely re-routed the pipe, with Rifeng hot melt pipe, pipe fittings are used Rifeng, the material costs about 500, the labor cost is 600, the electrical transformation (including telephone and network cable), most of the materials are used Zhengtai, the material cost is 3300 yuan, and the labor cost is 3000 yuan. I'm from the Heilongjiang region, so I should be about the same as you. You don't have this kind of algorithm.

Shenyang Jinde PPR pipe, the price is 40 yuan, and the circuit price is 25 yuan. The above prices are the prices of contracted labor and materials. But it does not include hardware faucets and switch panels.
