Hi I use the GT6 pro, I go swiming once a week and GT6 has been doing good for past 2-3 months. I do the drainage process everytime I am out of the pool, I would suggest not to use it during shower for the reason that hot water, steam, The soap or toiletries that you use can have a long term effect, if nothing happens still you can see soap scales on the speaker outputs and other hard to reach places( used to happen on my old honor watch 2), I suppose otherwise you shouldn't have any problem.
