The bathroom light at home is broken, and I want to change an LED light, which brand is better?

If the LED light is on, it is not bad, it is the power supply part of the lamp that is faulty, it should be the power supply regulator fault, and the LED lamp power supply voltage regulator ballast integrated plug-in is replaced.

As long as it is a toilet that is sold, it is installed in a package.

The toilet lid (toilet cover) is connected with the cushion, you have to buy a set when you buy it, the installation is very easy, you can do it yourself, remove the old toilet cover, there are 2 plastic gong bolts on the back edge of the toilet cover, and then screw it on yourself. Hope the answer helps!

You go to the shop and they can take care of the installation. If you have your own door, there are migrant workers in the street market, you can do this work. You'll have to bargain, though. This stuff is low-tech, be careful that they pay you more.

Whether to do waterproofing, it depends on the specific situation, one is to only replace the floor drain core, not to change the shell, so that there is no need to do waterproofing, normal replacement on the line, and the other is to replace the floor drain in a whole set, so that you need to do local waterproofing around the floor drain, as long as the new waterproof layer is covered with the old waterproof layer. When the whole set is replaced, it is generally in the case that the floor drain cannot be odorproof, or the room grid is too dense and the water is not good.
