Why Sloan water closets for commercial projects
- Built for high traffic with siphon-jet bowls and fully glazed 2-1/8" trapways, in floor-mounted and wall-hung formats; flush volumes typically span 1.1–1.6 gpf, determined by the flushometer you pair with the fixture.
- Current spec sheets show ADA options and performance claims such as MaP 1000 g when used with Sloan flushometers (model-dependent).
- Categories include Floor Mounted, Wall Hung, and Tank Toilets (pressure-assisted/gravity) with flushometer-like performance in tank options.
- Sloan offers WETS® “closet combos” (factory-paired water closet plus flushometer packages for proven performance, manual or sensor). These simplify submittals and purchasing.
How to choose the right Sloan toilet (fast selection guide)
- Mounting & outlet
-
- Floor-mounted, floor outlet: most common, bolt to the floor. ADA heights available.
- Wall-hung, wall outlet: maximizes floor clearance for easier cleaning; requires a carrier rated per ASME A112.6.1.
- Floor-mounted, rear outlet: for chase walls or specific rough-in constraints.
- Flush volume & valve match
-
- Sloan bowls are marked for a range (e.g., 1.1–1.6 gpf). The actual performance is set by the flushometer you select. Matching these is critical for code and performance.
- Compliance & height
-
- Accessible installations require 17–19 in seat height (top of seat to finished floor). Use ADA-height bowls or set wall-hung height accordingly.
- Water efficiency
-
- To hit WaterSense targets, pair WaterSense-listed flushometers with compatible Sloan bowls (commonly 1.28 gpf).
- Hygiene upgrades
-
- Consider bowls with SloanTec® hydrophobic antimicrobial glaze to resist buildup and simplify cleaning, available on select SKUs.

Installation & compliance notes (what inspectors look for)
- Match bowl + valve gpf (e.g., 1.28 gpf valve with a bowl rated for 1.28 gpf) for performance and labeling (including WaterSense where applicable).
- Provide 25–80 psi supply at the flushometer; Sloan spec sheets call out 25 psi minimum flowing for proper operation.
- Wall-hung bowls require a carrier conforming to ASME A112.6.1; set mounting height so the seat lands at 17–19 inches to meet ADA.
- Static load ratings: typical Sloan wall-hung models are 750 lb static; most spec sheets note “not recommended for bariatric use.” Use floor-mount if higher loads are expected.
Bundling for the deepest discounts (how we build your quote)
Because Sloan toilets are flushometer-driven systems, pricing improves when you bundle the entire restroom scope. We’ll package:
- The water closet(s) + the matched flushometers (manual or sensor).
- If wall-hung: carriers, gasket kits, and hardware.
- All supply/rough materials (vacuum breaker, stops, escutcheons), seats, and recommended service parts.
- We can also include compatible sinks, faucets, urinals, and accessories to complete a coordinated, code-compliant restroom design, ensuring you get everything you need in one package with the deepest possible discounts.
Send plans, counts, and performance goals (gpf targets, ADA needs, sensor preferences). We’ll return an optimized package price and submittal set.
Expert tips to avoid change orders
- Pick the performance first, then the valve. Start with your gpf target (1.28 gpf is common), then select the bowl and flushometer as a system (or choose a WETS® combo) to avoid mismatch.
- Mind the outlet type. Rear-outlet bowls (floor-mount or wall-hung) are for chase/plenum drainage, do not assume you can swap a floor-outlet bowl without re-roughing the line.
- Set wall-hung elevation for ADA. With wall-hung, ADA compliance is about seat height, adjust the carrier studs so you hit 17–19 inches finished.
- Specify SloanTec® where housekeeping is strained. The hydrophobic glaze makes day-to-day cleaning easier in high-use restrooms.

FAQs
Which Sloan toilet is the “best”?
“Best” depends on mounting and gpf. For floor-mount ADA, ST-2029 is a proven workhorse; for wall-hung, ST-2459 is the go-to, often sold in WETS combos with Royal flushometers. Both are rated for 1.1–1.6 gpf with 2-1/8" trapways and carry ADA/WaterSense options when paired with the right valve.
Do I need a special carrier for wall-hung Sloan toilets?
Yes, use a carrier conforming to ASME A112.6.1 and set the height so the seat is 17–19 inches above finished floor for ADA.
Can I run 1.28 gpf on any Sloan bowl?
Use only within the bowl’s rated range and with a matching WaterSense-listed flushometer. Many Sloan bowls are rated 1.1–1.6 gpf, but confirm on the spec sheet; the valve sets the delivered volume.
What water pressure do flushometers need?
Sloan spec sheets call for 25 psi minimum flowing pressure and ≤80 psi static. If pressure is marginal, discuss pressure/flow with your plumber before finalizing valves.
Is there a hygiene upgrade?
Yes, select Sloan bowls with SloanTec® glaze to resist mineral/soil buildup and simplify cleaning.
