I found the head height too low on
the MKII models so I completed this simple modification to raise
the head about 4.5 inches.
I unbolted the toilet (without
disconnecting any of the hoses), lifted the unit about 6 inches
and temporarily secured it with a couple of straps. I then made
a cardboard template of the base that the toilet sets on
(including the mounting holes). I then placed some scraps of
wood on the base to simulate the new height and I made a second
template for a new toilet mounting base (the new base is larger
due to the expanding sides of the hull).
I then temporarily replaced the
toilet and used the templates to cut out the wood. I used
marine plywood, 5/8" and several pieces of 4"x4" fence post.
After cutting all of the pieces, I glued and screwed, then did
multiple coats of exterior paint to match the original
fiberglass.
Finally I remounted the toilet to
the new base. I used the original lag screws for the lower
board mounting to the fiberglass base and several nuts/bolts w/
washers for the upper board.
The new height is much
more comfortable for adults. We even had a small "sit on the
head" party to demonstrate the improved feel.
