Our take on the TOTO Highland Arc Two-Piece Toilet

The Highland Arc is a two-piece vitreous china toilet with a round bowl and a 1.6 gallon-per-flush gravity flush. It stands out for its 16-1/8 inch bowl height, which sits between standard and comfort height, and a 2-1/8 inch trapway that resists clogging. It suits buyers who want a simple, reliable TOTO toilet without the brand's high-efficiency flush systems. Against TOTO's Drake and Ultramax lines it is a plainer toilet: no Tornado or Double Cyclone flush, no Cefiontect glaze, and a round bowl that takes up less depth but gives less seating room.

Pros
  • 16-1/8 inch bowl height is easier on knees than standard 15 inch bowls
  • Wide 2-1/8 inch trapway and 3 inch flush valve reduce clogging
  • Round bowl fits tight spaces and shortens the footprint
  • Two-piece design is straightforward to install and service
  • Vitreous china construction with TOTO's reputation for durable bowls
Cons
  • 1.6 gpf flush is less water-efficient than TOTO's 1.28 gpf models
  • No Tornado or Double Cyclone flush, so cleaning is less self-rinsing
  • No Cefiontect glaze to keep the bowl cleaner
  • Round bowl offers less seating area than an elongated one
  • At 94 lbs it is heavy to move and set alone

What reviewers say

Owner feedback on this model is limited, but TOTO two-piece toilets in this class are generally praised for dependable flushing and easy installation. Common complaints center on the round bowl's smaller seating area and the basic flush compared with TOTO's high-efficiency lines.

What people mention

  • Water useMixedThe 1.6 gpf flush uses more water than TOTO's 1.28 gpf toilets, which matters to some buyers.

Questions and answers

Is this toilet worth it over TOTO's Drake?
The Drake adds a more efficient 1.28 gpf Tornado flush and an elongated option, so it cleans itself better and uses less water. The Highland Arc is the simpler, lower-feature choice if you want a basic TOTO flush.
What rough-in does it need?
It uses a standard 12-inch rough-in, measured from the finished wall to the center of the drain. Check your existing rough-in before ordering, since 10 and 14 inch versions are not offered here.
Is the bowl comfort height?
At 16-1/8 inches it sits between standard height and the 16-1/2 to 17 inch comfort-height toilets. Most adults find it easier to use than a standard 15 inch bowl.
Does it come with a seat?
Two-piece toilets are typically sold as bowl and tank only, so plan on buying a round-front seat separately. Confirm the contents before ordering.
Will it fit in a small bathroom?
The round bowl and 26-3/8 inch depth make it a good fit for tight spaces. It is shorter front to back than most elongated toilets.
How much water does it use per flush?
It flushes at 1.6 gallons, the older standard. TOTO's high-efficiency models use 1.28 gallons or less.
Where is the TOTO Highland Arc Two-Piece Toilet cheapest?
At Amazon, for $358.67, as of our latest check.
