Bathroom shower units are popular among builders and homeowners thanks to the convenience of installing a single piece, pre-fabricated unit that comes equipped with all required fixtures. The installation itself can be handled as a DIY project with the following instructions.
Step 1 – Purchase a Bathroom Shower Unit
Measure the space in your bathroom where you intend to install the shower unit. Visit a bathroom supplies dealer and inquire about various models of bathroom shower units available. Choose a model that can fit in the space of your bathroom and make a purchase.
Step 2 – Prepare the Bathroom
Drain off the water from the tub and other draining pipes completely and let it dry. Turn off the water supply to the bathroom. Clean the bathroom with a rag cloth and keep it dry to have a clean working area. Determine hot and cold water connection pipes, showerhead pipe and the drain for waste water position. Measure the area available for the bathroom shower unit.
Step 3 – Assemble the Accessories
Unpack the unit and lay down all the accessories provided along with the unit. Identify which fixture should go to which place. If it is confusing, mark it with a pencil. It would be easier if you have the manufacturer supplied User Manual for assembling the unit ready in your hand. Clean the threads of the pipe for shower head and shower mixture and wrap a layer of thread tape on it. Connect all the fixtures given in the respective places. For fixing the shower head, you have to fix a pipe up the wall of the shower unit and sweat the brass female threaded winged fitting into the frame. Connect the shower head faucet.
Step 4 – Fix the Unit
Position the shower unit at floor level and see that the continuous flange fits snugly to the wall studs and the floor supports. Secure its position by screwing or hammering the nails through the flanges into the wall studs.
Step 5 – Drain Connection
Assemble the drain connections to the outlet from the shower unit and let this connection reach your waste water drain.
Step 6 – Water Supply
Connect the water supply connections from your permanent plumbing line in the walls to the respective pipes in the mixing valve of the bathroom shower unit.
Step 7 – Test the Installation
Restore the water supply to your bathroom and see if there is any leakage in any of the fixtures inside and outside the bathroom shower unit. If you see leakage, apply a sealant. If the leak is not controlled, turn off the water supply and redo the connection of that fixture by wrapping more thread tape in that area. Open your shower mixture valve and see the spraying of water from the shower faucet. This test will remove any debris or blocks if present. Check if the drain is working properly without any water seepage.
