         9 . A drain assembly for use with a plumbing system, the drain assembly comprising:
 a base including a first end, a second end opposite the first end, and defining a central axis, the base at least partially defining a channel that is open to both the first end and the second end, the channel having an inlet at the first end of the base;   a dome coupled to the base such that the dome at least partially encloses the inlet; and   a drain attachment removably coupled to one of the dome and the base, the drain attachment including a plurality of baffles, wherein at least one baffle of the plurality of baffles includes sidewalls oriented parallel to the central axis, wherein at least one baffle of the plurality of baffles defines an axial height that is greater than the axial height of the dome, and wherein the drain attachment defines a largest outer dimension that is greater than a largest outer dimension of the dome.   
     
     
         10 . The drain assembly of  claim 9 , wherein the drain attachment includes a first support ring and a second support ring that is disposed radially outward of the first support ring. 
     
     
         11 . The drain assembly of  claim 10 , wherein the plurality of baffles extends perpendicularly to the central axis from the first support ring toward the second support ring. 
     
     
         12 . The drain assembly of  claim 11 , wherein a first set of gaps are defined between adjacent baffles of the plurality of baffles, wherein a second set of gaps are defined by the dome, and wherein the plurality of baffles is configured to redirect the flow of fluid before the fluid flows through the second set of gaps. 
     
     
         13 . The drain assembly of  claim 9 , wherein the sidewalls of at least one baffle of the plurality of baffles are oriented perpendicular to the central axis. 
     
     
         14 . The drain assembly of  claim 9 , wherein the plurality of baffles of the drain attachment both axially and radially overlap the dome. 
     
     
         15 . A drain assembly for use with a plumbing system, the drain assembly comprising:
 a base including a first end, a second end opposite the first end, and defining a central axis, the base at least partially defining a channel extending along the central axis through the first end and the second end, the channel having an inlet at the first end of the base;   a dome coupled to the base such that the dome at least partially encloses the inlet, the dome at least partially defining a dome interior;   a first plurality of baffles at least partially positioned within the interior of the dome; and   a second plurality of baffles positioned outside the dome.
