We had our base and shower installed by a contractor and we love them. Base isn't flexing, which could be good installation, but I think it is also due to the thick hard material of the base. The no slip is just right. Not slippery, but not that sandpaper like surface either. Just bump textured, so it isn't slipery. Low lip, so no problems getting in or out for us.
Just ordered the commercial shower head to go with this base, it is all metal and trim is all medal, when looking at reviews from multiple sites, this was the best fit, am looking at other items and between Overstock an a couple other have saved thousands so far.
