I just bought a summer house with running water and septic system. It's mostly for the summer and the bath needs work. The toliet is cracked but one that is mounted to the wall with a support under the bowl to the floor. It is also leaking.

Second, the shower is a fiber glass, three piece, not original. It is mounted 10" above the floor like on a box. I have not open or broken into the box yet tro see what is in there, but I believe it is all the plumbing for the drain and supply.

Why would someone use or build the shower on a 10" box?

Why would you use a wall mounted toliet?

The house is a summer home, built on a craw space, with concrete blocks as a foundation. The water is turned off during the summer as well as the heat. Is this the reason, to keep all the pipes out of the craw space or something.

Looking for answers, thanks for your help.

mjager, Welcome to the DIY Forums.
Most common reason for building a box is that the drain was not where it needed to be for the shower (perhaps shower replaced a tub) and it was esier to mount the shower on a box than to change the drain piping. You'll probably see that when you open the box.
The wall mounted toilet may have been a freebie so it got installed. You will probably find waterlines in the crawlspace. If the water is shut off in the winter as is the heat, you need to drain the water lines and fill the traps on all fixtures with RV antifreeze before closing the place up in the winter. Thats most likely what caused the toilet to crack. Good luck with your project.
