I actually do code in the bathtub, but not like that. You can't reliably hold a laptop on your bare bent legs -- the lack of friction caused by leg hair will make it slide towards you (and into the water if the water is too high). If the guy were to put both hands on the keyboard and code, the laptop would not stay in place.
The only way to do it comfortably is to sit with your legs straight and flat in front of you (in a tub style bath, not a deep jacuzzi like pictured), raise the water level to about .75 inches (2cm) below the laptop (resting on your flat thighs), then lower the flow of water to a hot trickle and open the drain to match the in-flow. The hot trickle is to keep the temperature at a steady state of hotness.
My tub-style bath is not wide enough for my laptop to accidentally fall into the water to the side. The only way it could come in contact with water is if I sloshed around from side to side to make waves, which I don't do.
My brother marks his undergrad's papers from his bathtub, and frequently computes there. He has a wood board that goes across the tub. A compromise of ergonomics, but, he maintains its still the best.
So the legs would be like 4 inches and fit into the inside walls of the tub preventing the edge from slipping off the small ledge between the tub and the wall.
That way I could still code with the bathtub more than half full.
I'm about as far from a handyman as you can get, but I did manage to make one of these myself. The legs are only about 2" tall, but it sits snug with less than 1/8" wiggle room. While I don't use mine for bringing the laptop to the tub, it has been a delight for books and drinks.
Some occasional drops of water might hit the back of the case on my screen, but that doesn't really affect anything. Nothing gets over the screen and into the keyboard or any other openings.
