Spec-by-Spec Comparison
Detailed Comparison
Wall-hung cross-brand comparison: TOTO MH Wall-Hung ($720-820) and Kohler Veil Wall-Hung ($800-950). Both require in-wall carrier systems (sold separately, $400-700). Both elongated, both 1.28 GPF, both with concealed tank — the actuator plate at the wall is the only visible flush control.
Profile and proportions
The TOTO MH has a slimmer, more minimal profile — projects 19-20 inches from the wall, narrower bowl. Japanese-influenced minimalism. The Kohler Veil has slightly more substantial proportions — projects 21-22 inches, slightly wider bowl. American-contemporary aesthetic.
Carrier compatibility
Both work with Geberit Sigma carriers and TOTO carriers. Both work with Schluter, Wedi, and other premium carrier systems. Verify carrier compatibility with your specific install conditions (wall depth, drain location, etc).
Flush technology
The MH uses TOTO Tornado Flush — sustained vortex around bowl. The Veil uses Kohler AquaPiston canister flush — 360° water entry. Functionally equivalent. Both deliver MaP 1,000g performance at 1.28 GPF.
Glaze and bowl cleaning
The MH has TOTO's CeFiONtect glaze (anti-buildup ultra-smooth ceramic). The Veil has Kohler's Reveal glaze (anti-bacterial coating). Both reduce manual cleaning vs standard glazing.
Wall installation requirements
Both require: in-wall carrier with proper structural support, wall reframing in retrofit installations to accommodate carrier depth, drain rough-in at specific carrier-dictated location, water supply behind the wall, actuator plate at the wall surface. Installation: $1,500-3,500 in plumber + carpenter labor on top of unit + carrier costs.
Design language fit
The MH fits: Japanese-minimal bathrooms, Scandi-contemporary, European-modern. The Veil fits: American-contemporary, modern luxury, mid-century-influenced contemporary.
Resale considerations
Both wall-hung toilets command similar resale interest from contemporary-bathroom buyers. The Veil's American-brand recognition has marginal edge in standard US resale markets. Both look dramatically out-of-place in traditional bathroom remodels.
Final Verdict
We recommend the Kohler Veil Wall-Hung for buyers who want modern American-design consistency and slightly more substantial proportions. The TOTO MH Wall-Hung is the better pick for Japanese-influenced minimal bathrooms with tighter proportions where the slimmer profile is the design priority.
