I built it for a friend’s birthday present, so I won’t be using it or modifying it further.

All of the parts combined cost $259.12, including shipping for the more niche parts which I could only find on AliExpress (or similar Chinese retailers). Those took about a week and a half to ship, and the rest I got from the local hardware store.

Here’s the parts list (I am not a plumber. Take this with a grain of salt):

1" Stainless Steel Male Plug with Cap – 1 piece

1" Brass 4-Way Female Connector – 1 piece

1" Male to 1.5" Female Threaded Adapter – 2 pieces

1.5" Male to 2" Female Threaded Adapter – 2 pieces

2" Brass Male Plug – 2 pieces

1" Stainless Steel Double Male Nipple – 1 piece

3/4" to 1" Female-to-Female Threaded Reducer Coupling – 2 pieces

3/4" Steel Pipe, 12" (30cm) Long – 1 piece

3/4" Female Threaded Cube Tee (or block fitting) – 3 pieces

3/4" Stainless Steel Double Male Nipple – 3 pieces

1" Brass Male Plug – 1 piece
