Install Drainpipe:

- Locate or create a drain hole in the subfloor where the bathtub will be positioned. - Install the drainpipe vertically through the hole, ensuring it extends above the floor level. - Connect the bathtub drain assembly to the drainpipe below the subfloor. - Maintain the proper slope for efficient water drainage. 2.

Hot and Cold Water Supply Lines:

- Based on the bathtub model (e.g., freestanding, alcove, etc.), determine theの位置 of the hot and cold water supply lines. - Cut and measure PVC pipes to the required lengths. - Secure pipes to the wall studs or joists using pipe clamps. - Attach shutoff valves to the ends of the pipes, allowing you to turn off the water supply when needed. 3.

Faucet Valve Installation:

- If the bathtub has a faucet, install the rough-in valve. - Decide on the valve's location (e.g., on the wall or deck-mounted) and mark the spot. - Cut holes in the wall or tub deck to accommodate the valve. - Secure the valve with mounting brackets or screws. 4.

Faucet and Shower Connections:

- Depending on the type of bathtub faucet, connect the spout, handles, and showerhead using flexible PEX tubing or copper pipes. - Tighten all connections securely to prevent leaks. 5.

Test the Plumbing:

- Turn on the water supply to the bathtub and check for leaks. - Test the functionality of the faucet, handles, and showerhead to ensure they operate smoothly. 6.
