The Gerber Maxwell Crest is a 1.28 GPF two-piece toilet with an included soft-close seat, available with an elongated or round bowl. The elongated version measures 28.5 in deep, while the round one measures 28.13 in, so compare the shapes and dimensions with your available space.
Both versions include a wax ring and installation hardware. Gerber says the glazed trapway helps prevent clogs, but the rough-in dimension is not stated, so measure your existing setup before ordering.
Gerber Maxwell Crest toilet reviews: what stands out?
The Maxwell Crest's main features are its 1.28 GPF flush, included soft-close seat and two bowl-shape options. Both versions have a Fluidmaster 400A fill valve and 3 in flush valve.
Gerber Maxwell Crest Elongated Two-Piece Toilet: Best for elongated seating
- 1.28 GPF
- Elongated bowl
- Soft-close seat included
- 28.5 x 17.13 x 31 in
The elongated Maxwell Crest pairs a 1.28 GPF flush with an included soft-close seat and glazed trapway. Its dimensions are 28.5 in deep, 17.13 in wide and 31 in high.
Pros
- Soft-close seat included
- Fluidmaster 400A fill valve and 3 in flush valve
- Wax ring and installation hardware included
Cons
- The elongated bowl may need more front-to-back room than a round option
- Rough-in dimension is not stated
The elongated model has an oval bowl and measures 28.5 in deep. The round model measures 28.13 in deep.
Is the Maxwell Crest the right fit for your bathroom?
Pick the elongated version if you prefer an oval bowl and its dimensions suit your layout. Pick the round version if you prefer a round bowl and its dimensions fit your space.
Neither model's rough-in measurement is stated. Measure from the finished wall to the center of the toilet flange, then confirm the required rough-in with Gerber before buying.
Our guide to measuring toilet rough-in explains where to measure and what can affect that reading. If you're comparing bowl shapes, see round vs elongated toilets.
What features do the two Maxwell Crest models share?
Both versions use a 1.28 GPF flush system with a Fluidmaster 400A fill valve and 3 in flush valve. They also include a soft-close seat, wax ring and installation hardware.
| Feature | Elongated Maxwell Crest | Round Maxwell Crest |
|---|---|---|
| Bowl shape | Elongated | Round |
| Dimensions (D x W x H) | 28.5 x 17.13 x 31 in | 28.13 x 17.13 x 31 in |
| Flush rate | 1.28 GPF | 1.28 GPF |
| Seat | Soft-close, included | Soft-close, included |
| Trapway | Smooth glazed | Smooth glazed |
| Included parts | Bowl, tank with cover, hardware, wax ring, seat | Bowl, tank with cover, hardware, wax ring, seat |
| Installation | Floor mounted | Floor mounted |
Both models measure 17.13 in wide and 31 in high. These are toilet dimensions, not the clearance you need around the bowl or behind the tank.
Gerber says the glazed trapway helps waste flow and helps prevent clogs. This describes a design feature, not a promise that the toilet can't clog under any conditions.
Is the elongated or round Maxwell Crest better?
The elongated Maxwell Crest has an oval bowl, while the round model has a round bowl and a slightly shorter listed depth. Choose based on your preferred shape and the dimensions that fit your bathroom.
Gerber Maxwell Crest Round Two-Piece Toilet: Best for a round bowl
- 1.28 GPF
- Round bowl
- Soft-close seat included
- 28.13 x 17.13 x 31 in
This round version has the same stated flush rate and core features as the elongated model. It measures 28.13 in deep, 17.13 in wide and 31 in high.
Pros
- Round bowl
- Soft-close seat included
- Wax ring and installation hardware included
Cons
- Round seating may feel less spacious than elongated
- Rough-in dimension is not stated
The difference in depth is 0.37 in. Measure the full installation area instead of choosing based on that difference alone.
Check the path from the bathroom door to the toilet, too. A toilet can fit its floor footprint and still leave too little room for a door, vanity or nearby fixture.
For more help with seat height, compare the chair-height toilet guide. Bowl shape and seat height are separate choices, so check both if comfort is part of your decision.
What should you know about the flush and water use?
The Maxwell Crest uses 1.28 gallons per flush, and Gerber describes its flush as strong and bowl-clearing. The toilet has a 3 in flush valve and Fluidmaster 400A fill valve.
Gerber says the smooth glazed trapway helps waste flow and helps prevent clogs. Performance in a particular bathroom can also depend on installation, drainage and what enters the bowl.
The product data does not state a flush-performance test result or warranty term. If either matters to your decision, ask Gerber about the exact model number, GRS48310 for elongated or GRS48320 for round.
If conserving water is a priority, see our guide to WaterSense toilets. The stated 1.28 GPF rate does not confirm WaterSense certification.
What comes in the box, and what needs checking?
The Maxwell Crest includes the bowl, tank with cover, soft-close seat, wax ring and installation hardware. It is a floor-mounted two-piece toilet made of vitreous china.
Gerber describes a tool-free installation kit. Setup still depends on a compatible rough-in, a sound flange and correct installation, so follow Gerber's instructions and get a plumber's help if the flange or drain needs repair.
Before ordering, confirm the rough-in requirement, supply connection and clearance for the tank and bowl. The toilet dimensions help with planning, but they don't replace measurements of your bathroom.
How does the Gerber Viper Force compare?
The Viper Force is another Gerber 1.28 GPF elongated two-piece toilet, with an included soft-close seat. It measures 29.5 in deep, compared with 28.5 in for the elongated Maxwell Crest.
Gerber Viper Force Two-Piece Toilet: Best for removable-seat cleaning
- 1.28 GPF
- Elongated bowl
- Soft-close seat
- 29.5 x 16.5 x 31.75 in
The Viper Force is another Gerber 1.28 GPF elongated toilet. Its soft-close seat removes without tools, and it measures 29.5 in deep, 16.5 in wide and 31.75 in high.
Pros
- Seat removes without tools
- Fluidmaster 400A fill valve and 3 in flush valve
- Wax ring and installation hardware included
Cons
- Deeper and taller than the elongated Maxwell Crest
- Rough-in dimension is not stated
The Viper Force seat removes without tools, which may help when cleaning around the seat hinges. Its listed height is 31.75 in, compared with 31 in for either Maxwell Crest model.
Choose between them by dimensions and whether tool-free seat removal matters to you. Both have a stated 1.28 GPF flush rate and Fluidmaster 400A fill valve with a 3 in flush valve, but neither model's rough-in measurement is stated.
For another brand comparison, our guide to American Standard toilets covers the Cadet PRO, Colony and Champion lines. Check model-level dimensions and installation requirements rather than assuming every toilet in a brand range fits the same way.
When is the TOTO Drake a better alternative?
The TOTO Drake is worth comparing if you want its stated 12 in rough-in fit, Universal Height, TORNADO FLUSH and CEFIONTECT features. It uses 1.6 GPF, more than the Maxwell Crest's 1.28 GPF.
TOTO Drake Two-Piece Toilet, 1.6 GPF: Best for universal-height seating
- 1.6 GPF
- Elongated bowl
- Universal Height
- 28.38 x 17.19 x 30.13 in
The Drake uses 1.6 GPF and has TOTO's Universal Height, TORNADO FLUSH and CEFIONTECT. It includes the tank and bowl, while the seat, wax ring, mounting bolts and water supply line are separate.
Pros
- Universal Height is taller than a standard toilet
- TORNADO FLUSH and CEFIONTECT features
- 12 in rough-in fit is specified
Cons
- Uses more water per flush than the Maxwell Crest
- Wax ring, mounting bolts, water supply line and seat are separate
The Drake includes its bowl and tank, but the seat, wax ring, mounting bolts and water supply line are separate. That differs from the Maxwell Crest, which includes its soft-close seat, wax ring and installation hardware.
TOTO describes Universal Height as taller than a standard toilet and says it makes sitting down and standing up easier for many people. Height comfort varies by user, so compare the stated dimensions with your needs and bathroom setup.
Is the Gerber Maxwell Crest worth choosing?
Choose the elongated Maxwell Crest if its oval bowl and dimensions suit your space, or the round version if that shape and its dimensions work better. Both include the same stated flush features and installation components.
Consider the Viper Force if tool-free seat removal is useful, or compare the Drake if its Universal Height and stated rough-in fit match your plans. Before buying, confirm the rough-in and clearances; our toilet selection guide walks through other fit checks.

Frequently asked questions
What is the difference between the Gerber Maxwell Crest elongated and round toilets?
Both Maxwell Crest versions are white, floor-mounted two-piece toilets with a 1.28 GPF flush, soft-close seat, Fluidmaster 400A fill valve and 3 in flush valve. The elongated model measures 28.5 in deep; the round model measures 28.13 in deep.
Check the shape and available room before deciding.
Does the Gerber Maxwell Crest include a seat?
Yes. The elongated and round Maxwell Crest versions include a soft-close seat, along with the bowl, tank with cover, installation hardware and wax ring.
Measure your bathroom and confirm installation requirements, including the rough-in, before buying.
How much water does the Gerber Maxwell Crest use?
Both Maxwell Crest versions use 1.28 gallons per flush. Gerber describes the flush as high efficiency and says the glazed trapway helps prevent clogs.
Those are design features, not a guarantee that clogs can never happen.
Is the Gerber Maxwell Crest a good choice for a small bathroom?
The round version is slightly shorter in depth than the elongated version, at 28.13 in compared with 28.5 in. That small difference alone won't determine fit.
Measure from the wall to the front of the toilet, and check the rough-in, door swing and clearance around nearby fixtures.
