American Standard 18DB.9311800S.075 – Frequently Asked Questions

1) Do I need to buy drains separately for the Portsmouth 18DB.9311800S kitchen sink?
No. Two 9028000.075 drains ship with the sink, one for each bowl. Mounting hardware, the countertop cutout template and instructions are in the box as well. What is not included is the bottom grid set, ordered separately as 8447.311800.075 if you want scratch protection on the bowl floors.
2) How deep are the bowls on the American Standard Portsmouth double-bowl sink?
Nine inches deep, across a 32 x 18-inch double-bowl layout. Nine inches handles a stock pot or a sheet pan on edge while still leaving room under the cabinet for the P-trap and disposal, which is the usual trade-off against a 10-inch bowl.
3) Is 18-gauge stainless heavy enough for a busy kitchen sink?
The Portsmouth double-bowl is 18-gauge stainless steel, which is the heavier of the two common residential gauges and resists flexing and oil-canning better than 20-gauge. It is specified for residential use rather than commercial kitchens. The whole sink weighs 21.72 pounds.
4) Will this sink be noisy or sweat underneath like a cheap stainless sink?
Two things address that. SoundSecure+ rubber pads are applied to the bottom and the sides of the bowls to cut noise and vibration, and StoneLock multi-layer spray insulation covers the underside for sound absorption and to reduce condensation on the sink body. That matters if the sink sits over a cabinet with stored goods.
5) What finish does the 18DB.9311800S sink come in?
Stainless steel is the only finish offered, ordered under manufacturer part number 18DB.9311800S.075. There is no color or coated option in this model.
6) Is the Portsmouth 32-inch double-bowl sink suitable for an apartment or hotel job?
It is classed as a residential luxury sink in the American Standard Portsmouth family, so it suits single-family, condo and multi-family unit kitchens. For heavy commercial food service, specify a sink rated for commercial duty instead.
