I’ve installed more toilets than I can count—high-rises, historical homes, apartments, restaurants, and a few projects I still tell stories about at the counter. I’m Rick Callahan, Master Plumber and product expert at Plumbing Supply And More, and I’ll walk you through how to choose the right toilet the way pros really do it. If you’ve ever stood in a plumbing supply store aisle staring at a wall of bowls and tanks wondering what actually matters—flush ratings, bowl shapes, trapway sizes, rough-ins, seat heights—you’re in the right place.
Here’s the promise: you’ll walk away knowing exactly which specs to prioritize, the brands and models worth your money, and when it makes sense to spend a little more. And whenever you’re ready, our team at Plumbing Supply And More will help you match the right unit, parts, and install guidance—backed by inventory you can actually get today.
Start with the Rough-In and Room Dimensions
Your rough-in measurement is non-negotiable. Measure from the finished wall (not the baseboard) to the center of the flange bolts—most homes are 12 inches, but older properties often come in at 10 inches, and upscale or commercial builds sometimes use 14 inches.
- 10-inch rough-in options: Toto CST746CEMFG.10 Drake and Kohler K-3978-RA-0 Highline are solid choices. 12-inch rough-in options: This is the sweet spot with the widest selection—Toto Drake CST776CEFG, American Standard Cadet Pro 215CA.104, and Gerber Viper HE-21-312. 14-inch rough-in options: Look at Kohler K-3947 Wellworth 14" option or use a Toto Unifit adapter on compatible models like the Toto Carlyle II.
Pro tip: If you’re tight on space in a city condo bathroom, don’t ignore projection (how far the bowl sticks out). Some compact elongated bowls keep the comfort of elongated while staying under 28 inches deep—like the Kohler K-5172 Reach Curv or Toto Aimes.
Code and clearance: Most jurisdictions require 15 inches from centerline to each side wall and 24 inches of clear space in front. In our area, we see inspectors look closely at these numbers in multifamily remodels—ask us to cross-check your plan against local code before you buy.
Bowl Height and Shape: Comfort vs. Space
There are two decisions here: bowl shape (round vs. elongated) and bowl height (standard vs. comfort/ADA).
- Elongated bowls are more comfortable and common on modern installs. If space allows, choose elongated. If you’re under 28 inches to a door swing, consider compact-elongated models. Standard height is around 14–15 inches; “comfort height,” “chair height,” or ADA is typically 16–17 inches to the rim. For seniors or taller users, comfort height is a game-changer.
Real-world tip: I’ve had property managers switch entire buildings to comfort height after one trial floor—maintenance calls went down because users found them easier to use. For ADA compliance in commercial spaces, pair comfort-height bowls with properly mounted grab bars and verify clearances.
Seats matter. Many high-end bowls ship without seats. If you’re pairing a Toto with a washlet, verify the mounting pattern and overhang. Popular seat upgrades include Kohler K-4636 Cachet Quiet-Close and Bemis STA-TITE commercial seats—easy to tighten, won’t wobble loose.
Flush Technology: Gravity, Pressure-Assist, and Dual-Flush
Here’s where performance and noise meet the budget.
- Gravity-flush: Quiet, reliable, simple. Look for 1.28 GPF WaterSense-rated models. Toto Tornado Flush and American Standard PowerWash rim deliver strong, consistent clears. Pressure-assist: Excellent for commercial or heavy-use bathrooms, louder but powerful. Sloan Flushmate-equipped bowls (Gerber Avalanche PRO or Kohler Highline Pressure Lite) move waste decisively. Dual-flush: Saves water—0.8/1.28 GPF configurations. I like Toto Aquia IV with DynaMax Tornado Flush. These shine in multifamily or offices where water bills matter.
Trapway and siphon design: A fully glazed 2-1/8-inch trapway with a big water spot reduces streaking and clogs. Toto Drake and Kohler Highline do this well. My rule: if you can’t find trapway size in the spec sheet, skip it.
PI rating and MaP score: Aim for 800+ grams on MaP for residential; 1,000 grams for rentals and commercial. Ask our counter pros—we keep spec sheets and real-world feedback on hand.
One-Piece vs. Two-Piece vs. Wall-Hung
Each has a place.
- Two-piece: Most common and budget-friendly. Easier to carry upstairs. American Standard Cadet Pro or Kohler Cimarron are workhorses. One-piece: Sleeker, fewer crevices to clean, usually includes a better seat. Slightly higher cost and heavier to maneuver. Toto UltraMax II and Kohler Santa Rosa are customer favorites. Wall-hung: Great for tight spaces and modern design; needs an in-wall carrier like Geberit 111.335.00.5 or Sloan. Make sure the wall is framed to handle the load and you comply with local code.
Installation timeframes:
- Two-piece: 1.5–2.5 hours with a clean flange and shutoff. One-piece: 2–3 hours due to weight and alignment care. Wall-hung: Varies—4–8 hours including framing and carrier work.
Surface Finishes, Bowls, and Cleaning Performance
Want to spend less time scrubbing? Look for advanced bowl finishes and rim rinsing.
- Glaze coatings: Toto CEFIONTECT, American Standard EverClean, and Kohler CleanCoat reduce adherence and odors. They’re worth the upgrade—particularly in rentals or busy family homes. Rim design: Rimless or “tornado” rinse patterns clean better with each flush. Toto’s Tornado Flush and Kohler Revolution 360 are standouts. Skirted bowls: Easier to wipe down and hide the trapway. Install can be slightly trickier—budget an extra 20 minutes and make sure you’ve got the correct mounting kit.
Insider secret: Match supply line height to skirted bowls. Some skirted models need the stop and escutcheon positioned lower or offset. We’ll flag that before you run into drywall surgery on install day.
Brands and Models I Trust (With Real-World Pricing)
After 25 years, there are models I recommend without hesitation—based on call-backs (or lack of them), available parts, and user feedback.
- Toto Drake CST776CEFG (1.28 GPF, CEFIONTECT): $320–$480. My default for most homes. Reliable flush, easy install, parts readily available. Toto Aquia IV MS446124CEMG (dual-flush 0.8/1.28, CEFIONTECT): $530–$800. Great in condos or water-conscious properties; modern design. American Standard Cadet Pro 215CA.104 (1.28 GPF PowerWash): $240–$380. Budget-friendly, strong performance, ideal for property managers. Kohler Cimarron K-31621-0 (1.28 GPF Revolution 360): $350–$550. Solid balance of design and performance. Gerber Avalanche PRO HE-21-372 (1.28 GPF, pressure-assist options available): $260–$420. Tough in high-use environments. Wall-hung: Toto MH Wall-Hung with in-wall DuroMax carrier or Geberit carriers: $900–$1,600 for full system.
Seat upgrades: Bidet seats like Toto C5 or BioBidet BB-2000 pair well with elongated bowls—budget $280–$750. Confirm dedicated GFCI if adding heated features.
Supply Lines, Wax Rings, and the Small Parts That Make or Break the Job
Hardware matters. Don’t let a $3 ring cause a return visit.
- Wax: For residential, I prefer a wax ring with sleeve (Oatey or Harvey). For uneven flanges, use an extra-thick or stack only with care. In rentals or when you expect movement, consider a waxless solution like Fluidmaster Better Than Wax. Bolts: Solid brass closet bolts don’t snap during torque—worth the couple extra bucks. Supply lines: Stainless braided with a quality quarter-turn stop. If the stop is older than your first smartphone, replace it. Flange height: Ideal is flush with finished floor or up to 1/4 inch above. If it’s low, use a flange extender kit—not a mountain of wax.
Pro tip: If you smell sewer gas after install, 9 times out of 10 it’s a mis-seated ring or a crack in the flange. We carry repair rings and spacers that solve this without pulling the flange.
Water Efficiency, Rebates, and Local Code Alignment
Most regions now expect WaterSense 1.28 GPF or lower in new installs, and many municipalities offer rebates for dual-flush or high-efficiency ac supply house toilets. We track current incentives for contractors and homeowners—bring your address and we’ll check eligibility. For commercial jobs, verify with local code on flush volumes for public restrooms and consider pressure-assist where appropriate.
Seismic and anchoring: In certain seismic zones, we stock upgraded anchor kits and carriers. Ask our technical team if you manage buildings in older downtown structures—we’ve helped retrofit dozens to pass inspections cleanly.

FAQ: Toilets, Specs, and Selection
Q: What’s the best toilet for a small powder room with a 10-inch rough-in? A: Look at a compact elongated or round-front 10-inch model. I like the Toto CST746CEMFG.10 Drake or Kohler K-3978 Highline. Keep projection under 28 inches if a door swings in. We’ll confirm rough-in and door clearance at the counter.
Q: Gravity or pressure-assist for a restaurant restroom? A: Pressure-assist—Sloan Flushmate-equipped bowls like Gerber Avalanche PRO—handle heavy load with fewer clogs. They’re louder, but for commercial traffic it’s the right trade-off. For quiet upscale dining, a high-performance gravity model like Toto Drake with a large trapway can also work.
Q: Are dual-flush models reliable? A: The good ones are. Toto Aquia IV with DynaMax Tornado Flush is consistent and water-efficient. Make sure users understand the two button options; in offices we add small flush labels near the actuator.
Q: What’s the difference between CEFIONTECT, EverClean, and CleanCoat? A: All are advanced glazes that resist buildup and odors. CEFIONTECT (Toto), EverClean (American Standard), and CleanCoat (Kohler) help keep the bowl cleaner longer, especially with rimless rinse systems. They’re worth it for rentals and family baths.
Q: Do I need a new shutoff valve and supply line when I replace a toilet? A: If the stop is older or stiff—replace it. I recommend a quarter-turn ball stop and braided stainless line. It’s a low-cost upgrade that prevents leaks and future headaches.
Q: Can I install a wall-hung in a renovation? A: Yes, with proper framing and an in-wall carrier (Geberit or Sloan). We’ll verify stud layout, drain height, and venting. Expect more labor than a floor-mount, but the space savings and cleanability are excellent.
