Our take on the KOHLER K-3519-RA Highline Two-piece elongated toilet, 1.0 gpf, Right-Hand Trip Lever

The Kohler Highline Pressure Lite is a two-piece, floor-mount toilet with an elongated bowl and a pressure-assisted flush rated at 1.0 gpf. It uses a Sloan FLUSHMATE pressure vessel instead of a gravity tank, which gives a forceful flush and cuts water use well below standard 1.6 gpf models. The Comfort Height bowl sits at chair height, and the toilet is WaterSense certified and ADA compliant. It suits buyers chasing water savings, rebates or LEED credits, and commercial settings; the trade-off is that pressure-assisted toilets need at least 35 psi static pressure and are louder than gravity models.

Questions and answers

Does this toilet work in a low-water-pressure home?
It needs at least 35 psi static pressure and works best toward the upper end of the 35 to 80 psi range. Below that, the pressure-assisted flush weakens. Have a plumber check your pressure before buying.
How is it different from a standard gravity toilet?
It uses a Sloan FLUSHMATE pressure vessel rather than a gravity tank, so the flush is more forceful and uses 1.0 gpf instead of 1.6. The trade-off is more noise and a dependence on household water pressure.
What rough-in does it need?
It has a 12-inch rough-in, the common distance from the finished wall to the drain center. Measure yours before ordering.
Is the seat included?
No. The toilet is sold as the bowl and tank; a seat is bought separately. Look for an elongated seat with 5-1/2-inch seat-mounting hole spacing.
Does it qualify for water rebates?
It is WaterSense certified at 1.0 gpf, which many rebate programs and LEED credit calculations recognize. Confirm the specific program's requirements locally.
Which side is the trip lever on?
The lever is on the right-hand side as you face the toilet. Check that this matches your plumbing layout before installing.
