Thanks.
Well the water looks dark, but it's actually not, the apparent darkness is from
the reflection and lighting effects. Especially since the light is low in the
sky which is causing a lot of shadow within the tub. A different environment
and lighting scheme would likely show it much lighter.

Yes it is the same water with some parameter adjustments and ripples added.

I spit out a few quick examples with different environments.
Excuse the aliasing, I know it can be painful!

a picture is worth 1000 words? Water is clear for the most part, perhaps this is
bad example for an indoor tub, but I noticed the lighting in this outdoor photo;
tile is blue but the color in contrast shows the clarity.
Also couldn't get over the reflection and specular, once I got over the girl.
2 reasons I cut her out:
No one would look and the pool
I'd expect someone would have a cow
Anyway, take/find a picture, and you will see how close or far off you are.
Water; the ultimate challenge.

Don't know if you posted any script or what youre using for normals.
Here's a Cousin Ricky norm and the one I did for the Lego pool.
not in that order
#declare n_surface = normal {
function { f_ridge (x, y, z, 0.1, 1.0, 7, 0.7, 0.7, 0) } 2
// function { f_ridged_mf (x, y, z, 0.1, 3.0, 7, 0.7, 0.7, 2) } 2
}
//f_ridge = function { internal(58) }
// Parameters: x, y, z
// Six extra parameters required:
// 1. lambda
// 2. octaves
// 3. omega
// 4. offset
// 5. Ridge
// 6. noise
// Parameters: x, y, z
// Six extra parameters required:
// 1. H
// 2. Lacunarity
// 3. octaves
// 4. offset
// 5. Gain
// 6. noise

The water surface is f_ridged_mf(x,y,z, 0.1, 3, 7, 0.7, 0.7, 2) plus procedural,
hand placed ripples. It is not a normal though, but actually a heightfield.

Awesome!
But there's something lacking to give the whole thing a scale of sorts... the
way it is now, it could just as well be the size of a toy.
Maybe add some bump map decoration to the feet?

.... or use a shallower angle for the camera..?

Of these, I'd take the bottom left one.
