“One-piece” and “two-piece” here mostly describe where the pump lives, and that changes how the bathroom looks and how much room you have.
Two-piece (pump as a separate box)
The pump sits behind or beside the toilet as its own unit. It’s usually the more flexible setup because the pump often has extra inlets for a sink, shower, or tub.
- Best for: full basement bathrooms and anywhere you’ll tie in more fixtures
- Watch for: the pump box takes up floor space, so plan to hide it in a wall cabinet or chase
SNFLEX Two-Piece Macerating Toilet (600W)
The all-rounder. Two inlets on the pump let you tie in a sink and shower. The one most basement bathrooms need.

More pump for longer or higher runs, or when you’re tying in a shower and a sink on the same pump.
Check current priceOne-piece (pump built in or hidden behind)
The pump is tucked directly behind the bowl, so it looks more like a standard toilet and takes up less room.
- Best for: half baths, small spaces, and anyone who cares about looks
- Watch for: fewer extra inlets, so it’s not ideal if you want a shower on the same pump
