    You get an ADA compliant chair height and an elongated bowl that keeps things comfortable for everyday use. But keep in mind that the pressurized mechanism creates a distinct loud swoosh when you flush, so it is not the quietest option for a midnight trip to the bathroom.

    Homeowners dealing with a constantly running tank will appreciate how easily this replaces worn-out flappers and leaky seals. Just be aware that you will need to turn off the water supply and drain the tank completely before installation, which makes it a slightly messy Saturday afternoon project.

    VEVOR 500W Macerating Upflush Toilet System

    Basement Plumbing Hero

    View on Amazon

    Adding a bathroom below the main sewer line used to require breaking up your concrete floor, but this system solves that problem entirely. It features a 500-watt macerating pump that liquefies waste so it can travel horizontally and vertically through narrow pipes.

    This setup is ideal for basement conversions and attic additions where traditional gravity plumbing is impossible. The one drawback is that the electric pump housing sits visibly behind the bowl, which takes up a bit more floor space than a sleek standard model.

    • Brand:VEVOR

    • Additional Feature:Triple water inlets
    • Additional Feature:Dual flush water disposal
    • Additional Feature:Space saving layout

    Property managers and DIYers keep these on hand because they fit almost any standard bottom-feed tank design. However, if your toilet has an unusual proprietary flush mechanism, you might need to adjust the water level dial a few times to get the refill volume just right.

    • Brand:Fluidmaster
