A 48-inch trough sink is a practical choice for shared bathrooms where two people may need to wash up at the same time. The Eridanus 48-inch ceramic models are best for buyers who want a smooth vitreous-china surface and wall-mount or countertop installation; the Cpingao is better for shoppers seeking a wider stone-resin basin with two faucet holes. The 47-inch Weibath offers a matte finish, while the 43-inch Eridanus is a shorter alternative for bathrooms with less wall space.

Eridanus 48-Inch Ceramic Vessel Trough
This Eridanus sink measures 48 inches long, 16.5 inches wide, and 5.7 inches high. Its listing describes a double-bowl trough and supports both wall-mount and countertop vessel installation. That flexibility makes it a strong fit for remodelers who want to choose between a floating look and a counter-supported setup.
The sink is made from vitreous china with a smooth, non-porous surface. It has an overflow and a standard 1.75-inch drain opening, and the product includes wall-mounting screws and installation instructions. Best for: buyers seeking an exact 48-inch ceramic sink with two installation options. Limitation: confirm that the 16.5-inch depth and mounting arrangement fit the planned bathroom before purchase.
Eridanus 48-Inch Above-Counter Dual Trough
This model is also 48 by 16.5 inches, with a 5.7-inch height, vitreous-china construction, and an overflow. It is described as an above-counter dual trough, while the listing also provides for wall mounting. Its adjustable-height wall-mount approach can help buyers set the sink at a preferred height and keep the floor area open.
The 1.75-inch drain opening is specified as a standard size for a universal pop-up drain set. Mounting screws and instructions are included. Best for: households that want a full-width sink with a dual-trough layout and installation flexibility. Limitation: the listed information does not specify faucet-hole placement, so check faucet requirements and layout before selecting fixtures.
Weibath 47-Inch Matte White Double Bowl
The Weibath is a wall-mounted, 47-inch double-bowl trough made from stone resin. Its matte white surface and floating layout suit buyers aiming for a modern look while leaving the floor area visually open. The two basin areas are designed for side-by-side use, making this a useful option for shared bathrooms and busy morning routines.
Best for: shoppers who prioritize a matte finish and a clearly separated double-bowl design. It is one inch shorter than a 48-inch sink, which may help where the available wall run is slightly limited. Limitation: it does not meet an exact 48-inch width requirement, and the supplied details do not state drain or faucet-hole dimensions.
Cpingao 48-Inch Stone Resin Double Sink
This floating wall-mounted sink measures 48 inches long, 18 inches wide, and 5.51 inches high. Its basin is listed as 48 inches long, 13.82 inches wide, and 4.53 inches deep. The stone-resin construction has a matte white, non-porous surface described as resistant to scratches and marks.
The double-sink design includes two faucet holes, each listed at 1.38 inches in diameter, and a 1.77-inch drain opening. Best for: buyers who want a wider 48-inch option and need two faucet holes for simultaneous use. Limitation: at 18 inches wide, it needs more front-to-back room than the 16.5-inch Eridanus models.
Eridanus 43-Inch Ceramic Trough
This Eridanus measures 43.25 inches long, 16.5 inches wide, and 5.25 inches high. It is made from vitreous china, has an overflow, and uses a 1.75-inch drain opening. The listing describes both wall-mount and countertop installation, with mounting screws and instructions included.
Best for: buyers who like the Eridanus ceramic features but have less than 48 inches of available wall space. Its non-porous polished surface is described as low-absorption and acid-resistant. Limitation: this is not a 48-inch sink, so choose it only if the shorter length suits the bathroom plan.
Buying Guide: How To Choose A 48-Inch Trough Sink
Will the sink fit the available space?
Measure the wall or vanity area and compare both sink length and depth. Most options here are 16.5 inches deep, while the Cpingao is 18 inches deep. Allow for the planned faucet, plumbing, and nearby walls when checking the layout; the product dimensions alone do not confirm installation clearance.
Is wall mounting or countertop installation preferable?
A wall-mounted sink can leave the floor area open and lets the installer set the mounting height. Countertop or vessel installation may suit a plan that includes a supporting surface. The two Eridanus 48-inch listings specify both installation approaches; verify that the selected mounting method works with the bathroom structure and installation plan.
Which material and bowl layout fit your needs?
Choose vitreous china if you prefer a smooth, polished ceramic surface. Choose stone resin if a matte finish is a priority. For shared use, compare the listings’ double-bowl or dual-trough descriptions and check how the basins and faucet positions align with the number of users.
What drain and faucet details should you verify?
Compare the listed drain opening with the drain assembly you plan to use. The Eridanus models list 1.75-inch openings; Cpingao lists a 1.77-inch opening and two 1.38-inch faucet holes. Faucet-hole details are not provided for every sink, so confirm the required configuration before ordering.
