Best Extra Large Bathroom Sink Options for Spacious Vanities
If you need an extra large bathroom sink, confirm the basin’s actual dimensions before buying: the listed products do not include a clearly extra-large sink. The KOHLER Caxton is a rectangular undermount option, while the PROFLO Rockaway is a round drop-in model; both are better suited to buyers who can accept a more compact basin. The other picks are faucets or drain accessories that may suit a sink project but do not increase sink capacity.
| Product | Best For | Important Detail |
|---|---|---|
| KOHLER Caxton | Rectangular undermount installations | 20-1/4 by 15-11/16 inches; no faucet holes |
| PROFLO Rockaway | Drop-in installations | 19-inch round basin; three faucet holes |
| Hurran 4-Inch Centerset Faucet | Three-hole faucet layouts | Two handles and a high-arc spout |
| Cobbe Waterfall Faucet | Modern waterfall styling | 4-inch centerset; listed for 2- or 3-hole setups |
| Hibbent Drain Strainer | Drain control and debris capture | Pop-up stopper with removable basket |
KOHLER Caxton Rectangle Undermount Sink
The KOHLER Caxton is a white rectangular vitreous sink measuring 20-1/4 inches long by 15-11/16 inches wide. It has an overflow drain and is designed for undermount installation. Its clean basin shape can work with a vanity counter where an exposed rim is not wanted.
Best for: Buyers who want an undermount look and have a counter cutout suited to these dimensions. It is selected because it is one of the two actual sinks in the product list and has a longer rectangular footprint than the round alternative.
Limitation: It is not identified as extra large, and it has no faucet holes. Plan for a wall-mounted or counter-mounted faucet and check the required cutout dimensions before purchase.
PROFLO Rockaway 19-Inch Drop-In Sink
The PROFLO Rockaway is a 19-inch circular bathroom sink made of vitreous china. It uses a drop-in installation and comes pre-drilled with three faucet holes set at 4-inch centers. That layout can simplify matching the sink with a compatible centerset faucet.
Best for: Buyers replacing a round drop-in sink or choosing a basin for a counter opening and faucet arrangement that match its specifications. It earns a place here as the second listed sink option.
Limitation: A 19-inch round sink is not an extra-large basin. Check the counter opening and available vanity space, and avoid this choice if your priority is a wide rectangular washing area.
Hurran Matte Black Centerset Faucet
This Hurran faucet has a 4-inch centerset, two handles, and a high-arc spout that swivels 360 degrees. Listed spout height is 5.2 inches and reach is 4.8 inches. The product information also describes a 1.2-gpm aerator, ceramic cartridges, supply lines, and a matching pop-up drain with overflow.
Best for: Buyers fitting a compatible three-hole, 4-inch faucet layout who want separate hot- and cold-water controls. It is included as a practical fixture option for the PROFLO sink’s listed faucet-hole spacing.
Limitation: This is a faucet, not a sink, and it does not make a basin larger. Verify hole spacing and sink-deck clearance before selecting it.
Cobbe Matte Black Waterfall Faucet
The Cobbe faucet uses an open-top waterfall spout and a matte black finish. Its listed features include a 1.2-gpm flow rate, a three-layer filter, and construction from lead-free stainless steel. The product is described for 4-inch centerset installations and 2- or 3-hole configurations.
Best for: Buyers prioritizing a waterfall-style appearance and checking that the faucet configuration suits their sink. It offers a different visual and water-flow style from the two-handle Hurran option.
Limitation: The listing describes faucet configurations broadly; confirm the exact mounting arrangement and hole pattern needed for your sink. It is not a basin-size solution.
Hibbent 3-In-1 Pop-Up Drain Strainer
The Hibbent drain strainer combines water-holding, draining, and filtering functions. Its removable two-layer basket is designed to catch small debris and items, while removing the basket allows water to pass through larger openings. The pop-up mechanism switches between holding and draining modes.
Best for: Buyers who want a stopper and removable debris basket for a compatible bathroom sink drain. It is selected as a useful accessory when assembling or updating a sink setup.
Limitation: The listing says it is not suitable for bathtub drains. Confirm drain compatibility before buying; this accessory does not affect the sink’s dimensions.
Buying Guide: How to Choose an Extra Large Bathroom Sink
What size counts as extra large?
There is no single size shown in the supplied product information that defines “extra large.” Compare the sink’s exterior width and length, basin depth if provided, and usable interior area against your current sink. The listed KOHLER model measures 20-1/4 by 15-11/16 inches, and the PROFLO model is 19 inches round, so neither listing establishes an extra-large size.
Should you choose undermount or drop-in?
An undermount sink sits beneath the counter and requires a compatible counter opening. A drop-in sink rests in an opening with its rim on the counter. Choose based on the existing vanity, counter material, installation plan, and the basin style you prefer. Do not assume that one installation type offers more capacity without comparing actual interior measurements.
How should faucet holes affect the choice?
Match faucet mounting to the sink. The KOHLER Caxton has no faucet holes, so its product information calls for a wall- or counter-mounted faucet. The PROFLO has three holes at 4-inch centers, which points buyers toward a compatible faucet layout. Check the number and spacing of holes before ordering.
What else should you measure?
- Measure vanity width, depth, and available clearance around the basin.
- Check the countertop cutout and installation style.
- Confirm faucet-hole placement and the intended faucet mounting method.
- Check drain and overflow requirements against the sink and drain accessory.
- Compare the sink’s interior dimensions, not only its outside measurements.
Frequently Asked Questions
Which listed sink is the largest?
The KOHLER Caxton has listed dimensions of 20-1/4 by 15-11/16 inches. The PROFLO Rockaway is listed as 19 inches round. These measurements do not establish which has more usable basin capacity because interior dimensions and depth are not provided.
Is the KOHLER Caxton an extra-large sink?
The product information does not call it extra large. Its listed dimensions are 20-1/4 inches long by 15-11/16 inches wide, so compare those measurements with the space and capacity you need.
Can I use a 4-inch centerset faucet with the KOHLER sink?
The KOHLER Caxton has no faucet holes and requires a wall- or counter-mounted faucet, according to the product details. A deck-mounted centerset faucet may not suit this sink without a compatible counter arrangement.
Does the PROFLO sink include faucet holes?
Yes. The PROFLO Rockaway is pre-drilled with three faucet holes at 4-inch centers.
Does a drain strainer make a sink hold more water?
A drain stopper can hold water when closed, but it does not increase the sink’s basin size or capacity. Check that the drain accessory fits the sink before buying.
