What are the details that need to be dealt with when renovating the bathroom?

I've installed one house before, and I'm in the process of installing a second one. Common toilet configurations include hand basins, toilets, showers (baths or bidets), washing machines, water heaters, mirrors, and daily necessities placement.

In my experience, there are a few things to pay attention to when decorating a bathroom:

1.Water and water supply. The water supply and water supply should be well designed and appropriately located, including the distribution of hot and cold water.

2.Electricity. Equip washing machines, mirror lights, baths, etc. with waterproof sockets.

3.Watertight. The ground waterproofing must be foolproof, and it is best to do about 1 meter of wall waterproofing.

4.Ground level. Generally, it is slightly higher than the doorway to prevent water from flowing out.

5.Airy. Windowless toilets should be equipped with exhaust fans.

6.Overall planning. Estimate the size and location of the objects that will be placed in advance, such as toilets, hand basins, and bathtubs. Reserve space for washing machines, water heaters, bath rooms, etc., to minimize dead ends. Leave some space on the left and right of the toilet position, otherwise it will be inconvenient to use.

The most important thing is waterproofing.

Then there is the height of the towel.

So as not to take the towel master water backwards.
