还好我家装的非常基本，都是铺的地砖，去瓷砖店里当面选的，不容易掉包。我家换房门锁，是一个20，那种最普通的造型，圆的。大门的贵吧，我家整个换了防火大门，所以不知道锁多少钱了。

别给他钱，这事就算是吸取个教训。

我家装到完是2万整，包括 敲客厅和3个卧室的地面，重新铺（砖价格3.5 psf）,主人房厕所重新敲掉重装，厨房厨敲掉重装，2厕所门，1防火大门，3卧室门锁，油漆整间，客厅整个吊顶。我家是121平。现在进行到第4周，基本完工，已经清洗干净，还有些油漆没弄好的地方，厕所的挂件之类，需要再弄弄。估计这周就完事了。

第一周是敲砖和铺砖，第二周就是水管和安装马桶之类，我重新做了整间不锈钢的水管，马桶这些2间厕所里所有的安装费用是500左右，记不大清了，我可以把我的价格单分享给你

厨脚如果正常的话，正好压到下水道，最后还做了些调整，才避开。装修这些要考虑这么多的，之前都没有料到。你要量好呀
