Doesn't that drastically cut down the amount of water the tub will hold? A few more 2x4's and you could just box it in and use the entire tub volume. Well you'd have to seal those holes.
what i do for mine, (other than stock tanks) is a take 2-4 of them and put them inside eachother, makeing them stronger so they don't bow under water pressure.
