You will not be able to figure out this issue yourself, so contact a plumber for help. It's just that there are a lot of details in this process that not everyone knows. I also had problems with the bathroom, but a little more serious. The water in my bathroom was stagnant for a very long time. If the water is usually washed off immediately, then I could wash it off for several hours. Then I turned to the plumber, and he said that I need to change the pipes, as they are clogged. I already knew how much work it would take, so I decided to completely redo the bathroom. While I was changing the pipes, I ordered different things for the toilet on
Cotswold. In general, the bathroom renovation took me five months.
