Before beginning the install of your tub you need to make sure that the prep work or ‘roughing in’ is complete. The term “roughing in” means generally that the plumbing that needs to be in place is and the areas you are working with are prepped and ready to begin work on.
Here are some common mistakes people make when installing a bath tub that should be avoided:
- Using pipe that is too small, not making sure the fixtures are level, ignoring building codes, not using PTFE tape or pipe compound on the joints and not installing an air gap filling for the fixtures.
Now you’re ready to get started installing your new bathtub. Here are some steps to help you with your project.
• Make sure all piping is installed for the tub itself
• Lower the tub into place ( the flange needs to fit against the wall studs, it must rest on a 2 x 4 or 1 x 4 for complete support)
• You need to now assemble the drain connections, including the overflow drain above the trap.
• Run the hot and cold water lines to the tub mixing valve
• Run a pipe for the shower head from the water line up the wall, here you will need to sweat a female threaded winged fitting that is secured to a support
• The tub spout needs to be a ½” pipe extended according to the manufactures initial instruction.
• Sweat on a male threaded fitting at the end of the pipe. (you can use a brass nipple and ½” cap if you would prefer)
• Stop: here you need to have the roughed plumbing inspected
• Now you can restore the water pressure and check the drain connections and water lines for any leaks
• Water resistant drywall can be placed up now as a base for your new wall covering. (Here you can place sheets of backsplash or tile for the final look)
• Seal the joints between the wall and the new bathtub with some sort of silicone caulk to protect against water seepage/ damage
• The Spout can now be installed as well as the fixtures and shower head. Make sure to always clean the pipe threads, apply new pipe joint compound and or PTFE tape for more protection against leaks.
Job Well Done
Now let the tub dry in place for approximately 24 hours. Then draw a warm bath lay back and enjoy your handy work!
