Delta 9178T-DST vs Moen 7594ESRS: Touch or Motion?
By The Gear Audit Team · Specification research September 9, 2026; buying-advice and source check September 13, 2026.
Quick answer: deliberate touch or legacy dual-sensor motion?
Choose Delta Leland 9178T-DST when tapping the spout or handle is your preferred electronic command and you want a current exact-model path with one- or three-hole installation. Consider Moen Arbor 7594ESRS only when you specifically need its older Wave-and-Ready dual-sensor system or are replacing the same model. Its official store variant 48088996118838 was unavailable during the check; do not substitute the different 7594EWSRS Wave-only model.
Touch2O responds at the spout or handle and retains a manual lever, reducing accidental activation from a general sensing zone.
The older 7594ESRS provides Wave and Ready sensor zones, but version, included electronics and availability require extra checking.
Compare controls, flow evidence and installation
| Published attribute | Delta Leland 9178T-DST | Moen Arbor 7594ESRS |
|---|---|---|
| Electronic trigger | Touch2O: touch spout or handle | MotionSense Wave and Ready sensors |
| Manual control | Single lever | Single lever |
| Published flow | 1.8 gpm at 60 psi | Hosted series specification lists 1.5 gpm; older version-specific parts also list 2.0 gpm |
| Hole arrangement | One or three holes | One hole; verify version and escutcheon |
| Identity check | Match full finish/model suffix | Legacy dual-sensor 7594ESRS, not Wave-only 7594EWSRS |
Delta Leland 9178T-DST: touch as a deliberate command
Best for: A buyer who prefers tapping the faucet over reaching into a motion zone and needs a one- or three-hole installation path.
Delta lists Touch2O at the spout or handle, a manual lever, pull-down wand, ShieldSpray mode, MagnaTite docking and a TempSense indicator. The exact model page specifies 3/8-inch compression connections and 1.8 gpm at 60 psi.
Pros
- Touch activation is a deliberate physical command. It suits users who want electronic control without relying on where a hand enters a sensing zone.
- One- or three-hole installation broadens sink-deck fit. That can accommodate an existing three-hole arrangement when the exact installation parts are present.
- Magnetic docking and the temperature indicator add useful feedback. MagnaTite addresses wand return and TempSense communicates temperature state without making a performance claim.
Cons and trade-offs
- Touch2O is not hands-free motion control. Anyone who wants flow triggered without contacting the faucet has a clearer reason to seek a compatible motion model.
- The electronic system still needs under-sink room and power planning. Control components must coexist with shutoffs, disposal, filtration and free hose travel.
Choose something else if: Contact-free Wave and Ready sensing is a firm requirement and you can source and verify the older complete Moen system. Delta’s touch interaction will not imitate that workflow.
Our recommendation
We recommend 9178T-DST for buyers who consciously prefer tap control and whose sink and cabinet match its installation sheet. Confirm power components and clear hose movement before ordering.

Moen Arbor 7594ESRS: an older dual-sensor replacement case
Best for: Someone replacing or intentionally sourcing the exact Spot Resist Stainless 7594ESRS Wave-and-Ready system, with every electronic and power component verified.
The 7594E-series documentation describes a top Wave sensor, a Ready sensor below the spout and a manual lever. It lists a 68-inch braided pull-down hose, Reflex docking, six-AA battery power and an optional AC adapter with splitter. The exact 7594ESRS store variant is Spot Resist Stainless and was unavailable in the checked source.
Pros
- Two sensor zones support distinct hands-free triggers. Wave and Ready provide a different control model from Delta’s touch surface.
- The 68-inch braided hose and Reflex docking are documented. Those specifics help a replacement buyer compare the expected pull-down hardware.
- Battery power is standard and an AC path is documented. Six AA batteries avoid requiring a nearby outlet, while an optional adapter can suit a planned powered cabinet.
Cons and trade-offs
- The exact official-store variant was unavailable at the source check. Remaining-stock or used offers need careful inspection for model, condition and return terms.
- More than one 7594ESRS version exists. Series documentation lists 1.5 gpm while older version-specific parts show 2.0 gpm components, so flow and replacement parts must be matched to the actual unit.
Choose something else if: You want a straightforward current purchase, cannot confirm the complete legacy electronics, or prefer deliberate touch control. Delta 9178T-DST is the clearer comparison choice.
Our recommendation
Consider 7594ESRS only as a verified exact-model purchase or replacement. Match the suffix, version, flow-related parts, sensor hardware and power components before ordering; do not infer them from the Arbor family name.

Inspect the sink cabinet before choosing
- Confirm holes and deck thickness. Match the exact installation sheet and identify whether an escutcheon is required.
- Map cabinet space. Leave room for the control box, batteries or adapter, shutoffs and unhindered pull-down hose movement.
- Choose the trigger deliberately. Delta requires touch; the older Moen uses Wave and Ready motion zones.
- Verify every suffix and version. Finish, sensors, flow parts and included electronics can change with the exact model.
Electronic kitchen faucet FAQ
Is 7594EWSRS a direct replacement for 7594ESRS?
No. The checked 7594ESRS is an older dual-sensor Wave-and-Ready model; 7594EWSRS is a separate Wave-only model.
Can one flow number describe every 7594ESRS?
No. Moen warns of multiple versions, and its documents show both a 1.5 gpm series specification and older 2.0 gpm wand-related parts.
Do electronic controls remove the manual lever?
No. Both compared faucets document a single manual lever alongside their electronic trigger.
Research method, primary sources and limitations
We used Delta’s exact-model page and Moen’s official store, specifications and parts documents. We did not install either faucet or test sensing, leaks, splash or finish durability.
Buying-advice update: September 13, 2026. Original specification research: September 9, 2026. The later check reconfirmed store variant 48088996118838 as 7594ESRS and kept 7594EWSRS separate.
