A few years ago my husband and I used a product called Johnny Grip for our kitchen floor because it was way too slippery. It worked so well. Since then we have also used it on both bathroom floors and the actual shower floors themselves. I don't think the hardware stores carry such a product, hence why you haven't had any luck, but I know that you can do like we did and purchase it online.

My wife and I send our gratitude! Thanks for your help!

Anytime AmySue :) Glad I could help.

Harris99,

What about putting a non-slip bath mat in the bathtub? Here are a few that I found by putting that phrase in my browser, at ebay: http://www.ebay.com/sch/i.html?_nkw=bathtub+non+slip+mat. Did you want to not use a mat for some reason?

Bath mats are horrible to clean. Also, the one my father in law had in his bathroom slipped right out from under me and I nearly bashed my head on the tub faucet. His tub was much less slippery without it. We have a tub with a corrugated bottom, but with our softened water it is still slippery.

I have a slippery bath tub too. There are no surface treatment chemical or paint to sell in hardware store.

The tub becomes more and more slippery which makes me think it might be mildew which grows with time. After brushing the bathtub surface with Clorax, the problems is gone ! Easy, fast and save $$.

For best results, spray Colorax on surface and brush. Wait for 10 min, brush again.
