A rear-outlet toilet is the right starting point when bathroom plumbing exits through the wall rather than the floor. Among these options, the maceratingflo model is best suited to buyers seeking a close-coupled, two-piece rear-discharge toilet, while the Simple Project and SUPERFLO models emphasize a taller seat height. The Swiss Madison and Los Flexi options are wall-hung systems, not close-coupled toilets, so they suit buyers considering a different installation style. Check drain measurements and toilet configuration before choosing.
| Product | Configuration | Best suited for |
|---|---|---|
| maceratingflo Rear Outlet Toilet | Two-piece, rear discharge | Close-coupled style and 18-inch height |
| Simple Project Rear Outlet Toilet | Rear discharge | Buyers seeking a 19-inch height |
| SUPERFLO Rear Outlet Toilet | Rear discharge, dual flush | Water-saving flush choices |
| Swiss Madison Cascade | Wall-hung | Space-conscious wall-hung designs |
| Los Flexi Wall Hung System | Wall-hung system | A bundled carrier and dual-flush setup |
maceratingflo Two-Piece Rear Outlet Toilet
This is the closest match in the list for buyers searching for a close-coupled back-to-wall toilet. It is a two-piece toilet with a tank, elongated bowl, skirted design, and rear discharge for wall plumbing. The listed 18-inch height may suit taller users or people who prefer a higher seat.
Its 1.28 GPF flush is designed to use less water than higher-volume flushes. The product listing also specifies a P-trap and a 7-inch rough-in, with two extension pipes included. Choose this model if those dimensions match the bathroom and you want a conventional tank-and-bowl arrangement.
Limitation: Confirm the rear-drain position and included pipe requirements against the existing plumbing before ordering; the specified rough-in may not match every bathroom.
Simple Project 19-Inch Rear Outlet Toilet
The Simple Project toilet is best for buyers who prioritize a tall seat. Its listed 19-inch height is intended to make sitting and standing easier for seniors and people with stiff joints or mobility limitations. The P-trap design provides a water seal between the toilet and drain to help prevent drain odors from returning through the fixture.
Installation dimensions are especially important for this model. The product listing states that the center of the rear drain should be 7.5 inches above the floor. Measure from the finished floor to the drain center and compare that measurement before selecting this toilet.
Limitation: A mismatch in the stated drain height can lead to installation or drainage problems. Do not choose it based on bowl height alone.
SUPERFLO 19-Inch Rear Discharge Toilet
SUPERFLO is best for shoppers seeking both a higher bowl and dual-flush options. The listed flush choices are 1.28 GPF for a full flush and 0.8 GPF for a half flush. Its 19-inch height is intended to provide easier access for seniors and people with mobility challenges.
The P-trap design is listed for rear-drain and wall-drain installations. The manufacturer also notes that a macerator pump may broaden possible applications, but buyers should verify their plumbing needs and installation plan rather than assume a pump is required or included.
Limitation: The available details do not state a specific rear-drain rough-in measurement. Confirm required dimensions with the seller or installation documentation before purchase.
Swiss Madison Cascade Back-To-Wall Bowl
The Cascade is best for buyers who want a wall-hung toilet rather than a close-coupled, floor-mounted toilet. Its listed dual-flush controls offer a 0.8 GPF light flush and a 1.6 GPF full flush. A removable flush plate is intended to provide access to plumbing, and the built-in tank is described as a space-saving feature.
This design may appeal to homeowners planning a wall-hung installation and prioritizing visible floor space. It is not a direct substitute for a standard two-piece toilet: the wall-mounted configuration and tank arrangement differ.
Limitation: The listing identifies this as a bowl with a built-in tank arrangement but does not provide all installation dimensions here. Verify system requirements and wall preparation before choosing it.
Los Flexi Wall-Hung Toilet System
This package is best for buyers considering a complete wall-hung setup. The listed components include an elongated bowl, in-wall tank carrier, soft-close quick-release seat, and dual-flush push plate. Flush options are 0.8 and 1.6 GPF. The elongated bowl and quick-release seat are presented as features that can make cleaning more convenient.
Choose this system if a floating toilet and in-wall carrier suit the bathroom plan. Its dual-flush options are similar in volume to the Cascade’s, while the included carrier and seat make its listed package more extensive.
Limitation: This is a wall-hung system, not a close-coupled toilet. Confirm that the wall structure and planned installation accommodate an in-wall carrier.
Buying Guide: How To Choose A Rear-Outlet Toilet
Does the toilet match the drain location?
Measure from the finished floor to the center of the rear outlet, then compare that measurement with the product’s required rough-in. Also check outlet direction, available clearance, and any connector or extension-pipe requirements. The Simple Project listing gives a 7.5-inch drain-center measurement; the maceratingflo listing specifies a 7-inch rough-in. These measurements should not be treated as interchangeable.
Do you want close-coupled or wall-hung?
A close-coupled toilet has a tank attached to the bowl as a conventional unit. A wall-hung toilet suspends the bowl from the wall and uses an in-wall carrier or tank arrangement. The maceratingflo listing explicitly describes a two-piece toilet with a tank. The Cascade and Los Flexi products are wall-hung options, so compare them only if that installation style is suitable.
Which height and flush style fit your household?
The listed heights range from 18 inches for the maceratingflo toilet to 19 inches for the Simple Project and SUPERFLO models. Compare the measurement and intended user needs rather than assuming a taller bowl is right for everyone. For flush selection, SUPERFLO offers 1.28 and 0.8 GPF choices; the wall-hung products list 0.8 and 1.6 GPF options.
Frequently Asked Questions
What is a rear-outlet toilet?
A rear-outlet toilet connects to a drain through the wall behind the toilet instead of a floor drain. It must match the bathroom’s outlet position and plumbing dimensions.
Is a back-to-wall toilet the same as a wall-hung toilet?
No. “Back-to-wall” can describe a toilet positioned close to a wall, while “wall-hung” describes a bowl suspended from the wall. Check the product’s actual configuration.
Which listed model is explicitly two-piece?
The maceratingflo product is described as a two-piece rear-discharge toilet with a tank and elongated bowl.
Why measure the rear drain before buying?
The outlet height and rough-in affect whether the toilet can connect correctly. A mismatch may cause installation or drainage problems.
Which models offer dual flush?
SUPERFLO lists 1.28 and 0.8 GPF flushes. The Swiss Madison Cascade and Los Flexi system list 0.8 and 1.6 GPF options.
