The perfect bathmat is one of those brown fibre door mats, the kind people also use to get their car out of the snow. Always feels dry, never slips, and lasts for years.
Huh, I tried so many of those over the years and always hated the way they feel. Then a few years back, I discovered mats that are more like towels you can throw on the ground but thicker. So much better. The clincher was that I never knew how to clean the mats, but the towel- like ones can go in the wash whenever towels are cleaned
If you put a duck board on the floor then you can put any towel you like on top of it as your mat.
I’m one of the crew that mostly dries off in the shower where water can drain, and I dry each foot as I step out. There’s no need to handle more water.
I’ve used duck boards in outside showers, so I am familiar with them, but I’m not seeing a need inside, especially where we dry off before stepping out of the shower
