Depends what shower you have.
Use the safety shower if corrosive or irritating chemicals splash extensively on you or your clothing.
For sealing a shower door, it is recommended to use a waterproof silicone caulk.
For a shower, it is recommended to use a 2-inch drain size to ensure proper drainage and prevent clogging.
To conserve water.
Electricity and water don't mix. You should not have a socket in the shower.
You use it during the shower.
For a shower installation, it is recommended to use 1/2 inch PEX tubing.
I would use copper but it really doesn't matter. You can use what you are comfortable with.
Ideally, you should shower daily.
A heated mirror for a shower is highly preferred. Barring that, get a fogless mirror.
For tiling a shower, it is recommended to use a waterproof mortar, such as a polymer-modified thinset mortar. This type of mortar helps prevent water damage and ensures a strong bond between the tiles and the shower walls.
You should wash shower curtains by taking them down and using the tub to scrub in. You should use a diluted bleach, in order to prevent mold.
