Thanks,
Our tub is built from plywood and then the inside surface is covered with fiberglass matt, then it has a sand finish for grip. The edge is for the dirty belly dogs so that one can put their front feet up on it. Yes it is big and takes up space but then having your back not hurt is worth it. I have a ramp to get the older dogs in and out. Hmmm, going on the road for a tub building tour...sounds good to me, I love Canada!
