Is disposable bathtub film useful?

Useful.

Disposable bath film bags are necessary to use when you need to take a bath when staying in a hotel. Most bath film bags are lightweight, chemically stable, and will not rust; they have good insulation and thermal conductivity. Low.

The method of use is also relatively simple, just take off the disposable bathtub bag and put it on the bathtub. Then you can put water in the bag. Or spray the entire bathtub with flower spray first so that it will not slip, and then slowly spread it starting from the edge of the bathtub to cover the entire bathtub.
