There are a couple ways to accomplish this, more or less.
First you can change the properties of the Axes objects in the iSurface
Visualization Browser. Set the Line style and major and minor tick
lengths, for example, to create a grid.
However, that may not be enough control for a power user.
If you're up for an interesting challenge, you can always add your own
model trees into an iTools hierarchy. It just depends on how willing you
are to accept the fact that iTools doesn't actually "know" about them! For
many purposes, hacking into iTools' graphics makes sense, for example to
produce final printed output.
In the example of a surface, we can determine through OBJ_VALID()
and OBJ_ISA() you can find the reference to the IDLgrSurface object.
IDL> isurface, dist(30)
IDL> allobjects = obj_valid(/cast)
IDL> osurface = (allobjects[where(obj_isa(allobjects, 'idlgrsurface'))])[0]
Knowing that, you can find the parent object, which will be a model.
IDL> osurface->getproperty, parent = oparent
Now you can add your own graphics hierarchy, for example
IDL> omodel = obj_new('idlgrmodel')
IDL> oparent->add, omodel
IDL> opolygon = obj_new('idlgrpolygon', [0, 1, 1, 0]*29, [0, 0, 1, 1]*29, $
IDL> replicate(1.e-3, 4), style = 2, color = [255, 0, 0])
IDL> omodel->add, opolygon
The next time the iTool is updated (such as after an expose event), you'll
have a
red rectangle in the Z ~= 0 plane. Making a grid as shown with the MATLAB
output wouldn't be too much more work with a few IDLgrPolyline objects, or
perhaps the addition of more IDLgrAxis objects set up the exact way you want
them.
Of course to make your added visualization objects accessible "properly"
through the "Visualization Browser" window, you'd need to add these items
"the iTools way", but that's left as an exercise for the reader.

Not an iSurface plot, but you could try Plot_3DBox
if you get desperate. :-)
