How can I go about replacing the shower in my mobile home?

To replace the shower in your mobile home, you can start by measuring the dimensions of the existing shower space. Then, purchase a new shower unit that fits those dimensions. Remove the old shower unit carefully, making sure to turn off the water supply first. Install the new shower unit according to the manufacturer's instructions, ensuring a proper seal and connection to the water supply. Finally, test the new shower to ensure it is working correctly.
