I don't know about the dots that are appearing, but I wondered, since you want to leave the mat down, if you can't find one without suction cups, if these might be a good alternative?

>On a side note there are some small dark pin size holes in the bottom - is this a concern? Should they be addressed or filled in somehow by the guy who did the reglazing? We just had it done last week.

Absolutely you need to call them back. This sounds like the first stage of failure for the new finish, I'm sorry to say.

My old reglazed tub was very slippery, although I never used a mat. I think just a rubber mat w/o suction cups would work. I don't think mine had any dots in the finish. It lasted a good long time until I could remodel.

I used a peel and stick bathtub mat like they use in hotels. It was approved by my refinisher. I got mine at Safetybathmat.com. I love it. No more slimmy bath mats with suction cups. Much classier than stickers.

I live in an apartment that recommends no-suction cup mats. I found this one one Amazon: https://www.amazon.com/No-Suction-Cup-Bath-Mat/dp/B017TF1ANE

Does this bath mat get dirty looking like some I've seen? How do you keep it clean?

Still the question remains, what is the best material for the bath mat to use in a the reglazed tub Is rubber ok? I understand about no suction cups. I am pretty much happy with my mat with suction cups but will need having the tub reglazed and change my bath mat habits. Thoughts?

( no threads advices please )

No bath mat is safe with a reglazed tub. Reglazing is just painting. All painted tubs peel, and the use of a mat makes that happen much faster.
