My bad gores.
I must need my eyes checked. That cover looks grey but, that siding on the tub sure looks like a light tan to me.
Either way, you enjoy that tub. It's a neat set-up.
Interesting that you mentioned that. I also purchased a "grey" Coastal Grey tub. I was VERY surprised when a beige/tan tub appeared in my yard, with a gray cover!!
Now, I was also very pleased, as it pretty much exactly matches my vinyl siding--an Andersen Window's Sandtone color. A light tan! I just love it as it blends right in. I do not like the grey cover on it, however, but that's minor at this point. When it needs replacing, I'll look for a contrasting dark brown.
I almost hesitated to call the dealer about the color because I didn't want them to come and take the tub back--like if I had mistakenly received someone else's tub!
They insisted that it is Coastal Grey, so I love my Coastal Grey beige tub!
