a glazed tub that i got about 15 years ago. Great job, but now that I
am in a senior stage, i fear of tripping in the tub as I shower. I
almost did already. I was told by the installer at the time, not to
put any of those decals that prevent slipping, cause it would
eventually reveal the color that the tub was prior. Any suggestions

They also sell them in whole mats with suckers on the bottom.
