Bobrick B-532 Countertop-Mounted Circular Waste Chute, Flat Flange, Satin Finish

Public restrooms with under-counter waste systems need a way to get waste from the countertop into the bin below without a freestanding trash can taking up floor or counter space. The Bobrick B-532 is the specified solution: a circular chute that mounts flush into the countertop, accepts hand towels and waste through the opening, and deposits directly into an under-counter waste receptacle. The result is a cleaner-looking vanity area, faster user flow, and no exposed trash can for staff to manage. As a Bobrick Premier Partner, Total Restroom stocks the B-532 with a Low Price Guarantee.

Countertop-Flush Installation — Three Mounting Options
The B-532's flat flange sits on top of any standard countertop and works in three configurations: surface counter installation, recessed (flush with the stone/laminate), or under-counter mounted. Requires a 6-1/8" ± 1/16" (155 ± 1.5mm) diameter hole cut in the countertop. The chute body extends below the surface and should be sealed with silicone sealant (not furnished) for a permanent, sanitary installation.

Waste Receptacle Not Included — Size Your Bin Separately
The B-532 is the chute only — the under-counter waste receptacle is a separate purchase. This is intentional: the chute is compatible with a range of bin sizes, letting you match capacity to traffic volume. Contact our team for receptacle pairing recommendations.

Type-300 Stainless Steel, 22-Gauge — TrimLine Series Quality
The B-532 is part of Bobrick's TrimLine Series — their commercial-grade coordinated accessory line. Construction is heavy-duty 22-gauge type-300 stainless steel with a satin finish on all exposed surfaces. It coordinates visually with other TrimLine Series accessories (soap dispensers, paper towel dispensers, and toilet tissue dispensers) for a unified restroom aesthetic.

Satin Finish Resists Commercial Cleaning
The Type-30o satin stainless exterior holds up to daily commercial cleaning without corroding or discoloring. The smooth interior of the chute allows waste to drop cleanly into the bin without catching or snagging.

FAQ

Does the B-532 come with a waste bin?
No. The B-532 is the countertop chute only. You'll need to purchase an under-counter waste receptacle separately and position it below the countertop opening to catch waste. Contact our team for compatible receptacle options.

What size hole does the countertop need?
A 6-1/8" ± 1/16" (approximately 155mm) diameter hole. The unit's outer flange (6-3/16") sits on top of the counter surface. Silicone sealant is used to seal the unit in place — not included.

Can this be used in a new countertop installation or only retrofitted?
Both. It's commonly specified in new restroom construction as part of a coordinated TrimLine vanity system, and it can also be retrofit into existing solid-surface, laminate, or stone countertops as long as the hole can be cut to spec.

Does it coordinate with other Bobrick TrimLine accessories?
Yes — the B-532 is part of the TrimLine Series, which includes soap dispensers, paper towel dispensers, toilet tissue dispensers, and sanitary disposal units. All share the same satin stainless finish and visual profile.
