simpleprojectus Toilets Bidets Buying Guide — Part 1: Models and Features Compared

Start here: Which type fits your project?

Use these common bathroom scenarios to narrow your shortlist before comparing individual specs like pumping distance, seat height, or bowl shape.

• No floor drain or you’re finishing a basement bathroom: choose an upflush (macerating) system. Options: SNFLEX Two-Piece Macerating Toilet | 500W Upflush Toilet, SNFLEX Two-Piece Macerating Toilet | 600W Upflush Toilet, SNFLEX Two-Piece Macerating Toilet | 750W Upflush Toilet, or the integrated-look SNFLEX One-Piece Macerating Toilet | 600W Upflush Toilet.
• Easier sit-to-stand (home ergonomics): 21" class extra-tall picks include ELEMAZ 21" Extra Tall Toilet for Seniors & Tall Adults | Elongated Bowl, ELEMAZ 21" Extra Tall Toilet for Seniors & Tall Adults | Dual Flush MAP 1000g, ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet | Elongated Black Toilet, ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet | Elongated Bone Toilet, and the space-saving round bowl ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet Round Bowl | Space-saving.
• ADA-height target (17–19 inches) with a wall connection: ELEMAZ 19" Tall Toilet | ADA Height Toilet Rear Discharge.
• Tiny or awkward spaces: corner-fit SKIFLEX 17.2" Corner Compact Toilet | Comfort Height or the sink-on-top combo Toilet with Sink on Top | 2 in 1 Toilet Sink Combo Comfort Height.
• Repairing a cracked or mismatched tank on a compatible two-piece Simple Project bowl: Durable Toilet Tank for Two-Piece Toilets | Tank Lid Included.

SNFLEX upflush (macerating) systems: power tiers, form factors, and pump-only options

If you’re adding a bathroom below the main drain line or anywhere you’d rather not break concrete, an upflush toilet routes waste through a macerator pump that discharges to your existing plumbing. Choose power based on your total pipe run and fixture load.

• Pumping distance guidelines (manufacturer-listed): • SNFLEX Two-Piece Macerating Toilet | 500W Upflush Toilet ≈ 23 ft vertical / 230 ft horizontal; • SNFLEX Two-Piece Macerating Toilet | 600W Upflush Toilet ≈ 29 ft / 295 ft; • SNFLEX Two-Piece Macerating Toilet | 750W Upflush Toilet ≈ 36 ft / 360 ft.
• Fixture capacity example: SNFLEX Two-Piece Macerating Toilet | 600W Upflush Toilet is listed to support a full-bath load (toilet + sink + shower/tub + washer).
• Noise and power: the 500W and 600W listings cite about 35–45 dB(A). All SNFLEX units use a 110–120V supply; the 600W two-piece page specifies a GFCI outlet.
• One-piece vs two-piece: SNFLEX One-Piece Macerating Toilet | 600W Upflush Toilet integrates and hides the pump behind the toilet for a cleaner look and similar 29 ft/295 ft reach. Two-piece kits externalize the macerator box for service access and flexible tie-ins.
• Pump-only upgrades/replacements: SNFLEX Macerator Pump for Two Piece Upflush Toilet | 600W & 750W - 600W and SNFLEX Macerator Pump for Two Piece Upflush Toilet | 600W & 750W - 750W include a built-in check valve and carbon filter with cut-to-fit outlet sizing to adapt to your line.
• Included accessories called out on product pages: the 500W two-piece kit notes an extension pipe and external check valve included.
• Important install notes: follow local code for venting and electrical; maintain proper fall on horizontal runs; and never substitute model-specific parts without verifying compatibility with the SNFLEX manual. Avoid flushing wipes or non–toilet-paper items—check your owner’s guide for acceptable materials.

Tall and ADA-height ergonomics: ELEMAZ lineup compared

Seat height changes comfort and leverage. ADA for adult toilets specifies 17–19 inches to the top of the seat in public/common-use facilities. Extra-tall 21" class models can be easier for some home users but exceed ADA’s public-use range; use ADA-height if code requires it.

• 21" class, elongated bowl (single-flush): ELEMAZ 21" Extra Tall Toilet for Seniors & Tall Adults | Elongated Bowl lists 1.28 gpf, two-piece, 12" rough-in; matching finishes include ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet | Elongated Black Toilet and ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet | Elongated Bone Toilet (same 1.28 gpf spec per listings).
• 21" class, elongated bowl (dual-flush, performance claim): ELEMAZ 21" Extra Tall Toilet for Seniors & Tall Adults | Dual Flush MAP 1000g lists 1.28/0.8 gpf and a claimed MaP 1000g; seat height is listed around 21.8" to the seat top; 12" rough-in.
• 21" class, round bowl (space-saving): ELEMAZ 21" Extra Tall Toilet | ADA Height Toilet Round Bowl | Space-saving is a round-bowl variant with a single 1.28 gpf flush; the page lists a bowl height around 19.9"; 12" rough-in.
• ADA-height rear outlet (17–19"): ELEMAZ 19" Tall Toilet | ADA Height Toilet Rear Discharge uses a rear discharge with dual-flush 0.8/1.28 gpf; the outlet center is listed around 7.5" above the floor and the kit includes an extension pipe. Confirm your wall connection height before purchase.

Small-space solutions: corner fit or 2‑in‑1 sink combo

If you’re optimizing every inch, these layouts reduce projection and combine functions without sacrificing standard connections.

• Corner install: SKIFLEX 17.2" Corner Compact Toilet | Comfort Height uses a 12" rough-in, has a 17.2" comfort-height seat, elongated bowl, and dual 0.8/1.28 gpf. Key fit dims on the page include about 32.7" from the corner to the front of the bowl and roughly 25.2" from the corner to each wall side.
• 2‑in‑1 greywater reuse: Toilet with Sink on Top | 2 in 1 Toilet Sink Combo Comfort Height routes the faucet drain into the tank to supply the next flush. The faucet operates independently of flushing. Listing notes: two-piece design, elongated bowl, single 1.28 gpf, ~17" seat height, ~7.1" faucet height, and a standard 12" rough-in.

Fitment, standards, and verification checklist

Before you buy, verify the dimensions and any third-party labels that matter for rebates or permitting.

• Rough-in and projection: all gravity models here list a standard 12" rough-in; the SKIFLEX corner layout publishes corner-to-front and side clearances—measure twice against your framing and door swing.
• Rear-discharge alignment: ELEMAZ 19" Tall Toilet | ADA Height Toilet Rear Discharge lists an outlet-center ~7.5" off the floor. Confirm your wall carrier or wall stub-out height and use the included extension pipe per the manual.
• Water use and WaterSense: many listings specify 1.28 gpf or dual 1.28/0.8 gpf. If you need the actual EPA WaterSense label for a rebate or code path, search the exact model on EPA’s WaterSense product database (note: updated Version 2.0 requires dual-flush full-flush ≤1.28 gpf after Dec 31, 2025).
• Flush performance (MaP): the dual-flush ELEMAZ 21" Extra Tall Toilet for Seniors & Tall Adults | Dual Flush MAP 1000g page claims a 1000g MaP result. When label-sensitive, verify the specific model on MaP’s public database.
• Electrical and sound for upflush: SNFLEX units use 110–120V; the 600W two-piece page specifies a GFCI outlet. Listed sound for 500W/600W models is about 35–45 dB(A).
• What’s in the box (callouts from listings): the 500W two-piece kit notes an extension pipe and external check valve; SNFLEX pump-only kits include a built-in carbon filter and check valve with multiple outlet-size adapters.

Comparing to familiar brands and add-on bidet seats

Shoppers often compare a standard toilet plus electric bidet seat (e.g., TOTO Washlet, Kohler PureWash, Brondell Swash, Bio Bidet) against integrated smart toilets. The models in this guide are conventional gravity or macerating toilets; to add washlet-style features, choose a compatible seat shape (elongated vs round) and ensure a nearby GFCI for electric seats. This lets you pair an ELEMAZ or SNFLEX bowl with a preferred bidet seat brand while keeping the core toilet type you need (upflush, rear-outlet, corner, extra-tall).

What buyers liked (from public discussions)

These themes reflect positive sentiments we saw in public conversations. They are not performance proofs; always rely on manufacturer specifications and codes.

• Upflush freedom without breaking concrete—particularly when tying in a sink or shower to a macerator box for a basement bath. Example threads: https://www.reddit.com/r/HomeImprovement/comments/lpxubp and https://www.reddit.com/r/askaplumber/comments/1uc3b7a/upflush_toilet_help/
• Comfort gains from extra-tall seating for seniors or tall adults, with fewer complaints about knee strain. Example: https://www.reddit.com/r/askaplumber/comments/proga1
• Creative space saves using corner toilets and sink-on-top combos in micro-baths. Examples: https://www.reddit.com/r/HomeDecorating/comments/1byb7io
