Every LUVUL sink is handmade from 16-gauge (1.5 mm), type 304 stainless steel, 18/10 chrome-nickel: chromium for corrosion resistance and nickel for strength and an even satin finish. It is the same alloy family used in professional kitchens.

Gauge is a thickness scale where a lower number means thicker steel. 16-gauge is about 1/16 in. (approx. 1.5 mm) thick, noticeably heavier than the 18- and 20-gauge steel used in many entry-level sinks. Thicker steel flexes less, resists dents better and transmits less noise.

304 stainless steel is highly corrosion-resistant because chromium forms an invisible protective layer on the surface. The steel itself does not rust under normal household use. What people usually see as 'rust' is iron from something else (cast iron pans, steel wool, water pipes, a wet can) left on the surface. See 'I see small rust-colored spots' in the troubleshooting section for how to remove them.

The bowls are formed, welded and finished by skilled craftspeople rather than deep-drawn from a single sheet in one press stroke. This is what allows tight R10 corners, straight walls and flat bottoms with engineered slopes. Because each sink is hand-finished, tiny variations in the satin brushing pattern are normal and are not defects.

R10 describes a 10 mm (about 3/8 in.) inside corner radius. It gives the sink a crisp, contemporary look and more usable flat bottom area than a traditional rounded bowl, while still being easy to wipe clean, unlike a sharp zero-radius corner.

Speedy Drain is LUVUL's sloped bottom design: the floor of the bowl is shaped with subtle grooves/pitches that guide water toward the drain so it does not sit in puddles. It helps the sink dry faster and reduces water spots and mineral build-up.

A satin (brushed) finish with a fine directional grain. Satin finishes are chosen for kitchens because they soften the look of fingerprints, water marks and light everyday scratches much better than mirror-polished steel.

Yes. Sound-absorbing pads are applied to the underside of the bowls to reduce the ringing of running water and dishes. They also help reduce condensation under the sink. Do not remove or cut the pads during installation.

Yes, LUVUL sinks are cUPC certified, meaning they have been tested and listed to North American plumbing standards for use in the United States and Canada. Ask us if your inspector needs a copy of the certificate.

LUVUL sinks are made for indoor kitchens, bars and laundry rooms. Marine and outdoor installations are not covered by the warranty. For industrial, commercial or business use, the warranty is one (1) year. Talk to us before installing in these settings.

Yes. Stainless steel handles heat very well. When draining boiling water (pasta, for example), run some cold water at the same time to protect your drain pipes and the plastic parts of a garbage disposal, not the sink itself.

Measure the inside width of the sink base cabinet. For an undermount sink, the outside dimensions of the sink (including the flange) must fit inside the cabinet walls with some clearance for mounting clips and plumbing. As a rule of thumb, most people pick a sink roughly 3 in. narrower than the cabinet's nominal width (for example, a 33 in. sink for a 36 in. base). Always confirm with the sink's spec sheet and your fabricator.

Type the part # from your box label at luvul.com/product-data. Each part number has its own page with outside and bowl dimensions, depth, drain position, minimum cabinet, a plan drawing, a printable spec sheet and the DWG file.

Each part number has a plan drawing and a CAD (DWG) file on its product page. Always verify any template against the actual sink before cutting stone; print scale can vary, so measure a known dimension on the printout first.

Three common options: zero/flush reveal (countertop edge aligns with the sink wall), positive reveal (a small ledge of the sink rim is visible), and negative reveal (the countertop overhangs the bowl slightly). With R10 corners, a zero or slight negative reveal gives the cleanest look. Agree on the reveal with your fabricator before the countertop is cut.

Undermount sinks go into solid surfaces: granite, quartz, marble, quartzite, porcelain slab, concrete and solid surface. Undermounting in laminate or tile over plywood is not recommended because the cut edge is exposed to water. For laminate, choose one of our drop-in models.

Plan at least 2 to 3 in. of countertop between the back edge of the cutout and the backsplash for a standard single-hole faucet, more for faucets with a separate side sprayer, soap dispenser or air gap. Check the faucet maker's deck-plate and handle-swing dimensions.

Only the models listed as drop-in are made to sit on top of the counter. Undermount and farmhouse models are not designed to be dropped in. The installation type is on every product data page.

Undermount and farmhouse models have no faucet holes: the faucet mounts on the countertop or wall. Some drop-in models come with faucet holes; the count is on each product data page. Never drill a stainless sink yourself. Drilling distorts the steel, leaves heat marks, and alteration of the product is not covered by the warranty.

We recommend a professional countertop fabricator for the undermount mounting and a licensed plumber for the drain and water connections. Follow your local code requirements.

Before installation: (1) unbox the sink and inspect all surfaces under good light for dents, deep scratches or finish issues; (2) confirm the model, size and all included parts against the packing list; (3) dry-fit the sink under the cutout. Report anything wrong before installing. Once a sink is installed, cosmetic issues that would have been visible beforehand are much harder to resolve.

Use a 100% silicone sealant rated for kitchen and bath use between the sink rim and the countertop, together with the mounting clips or a sink support system. Do not use construction adhesives, plumber's putty on stone, or products that can stain natural stone. Clean excess silicone before it cures.

For countertops thicker than standard 3 cm (about 1-1/4 in.), or with a thick sub-top, you may need longer hardware or a sink-support rail or bracket system. Contact us with your countertop thickness.

Yes, for undermount installs we recommend that the sink be supported by the mounting clips plus an under-sink support (rail, bracket or wooden frame) sized for the full weight of the sink filled with water and dishes. Large single bowls and laundry sinks especially benefit from extra support.

Keep any protective film or cardboard on the sink during fabrication and installation to protect the finish from grit and tools, then remove it once the countertop work is finished. Do not let it sit in direct sun for long periods, which can make the adhesive harder to remove.

Construction dust, metal filings from nearby cutting, grout, thin-set and silicone residue can all mark the surface. After installation, rinse the sink, wash it with mild dish soap, and remove any metal filings immediately, as they rust quickly and leave orange spots. Remove cured silicone with a plastic scraper, never a metal blade.

Avoid it. Stone slurry, grinding dust and steel particles from cutting tools can scratch the satin finish and leave iron spots. If work must be done nearby, keep the sink covered and rinse it thoroughly afterward.

The drain opening is 3 9/16 in (90 mm), the standard North American kitchen size, so it fits standard basket strainers and garbage disposals.

Max+ packs include the All Metal Sink Strainer Basket And Lid, 417887 (two on double-bowl models). Each product data page lists exactly what is in the box for your part number. Before installing, check the strainer body, basket, gaskets and locknut.

Yes. The 3 9/16 in (90 mm) drain opening accepts most major disposal brands using the disposal's own mounting flange. Follow the disposal maker's instructions and use a plumber if you are not comfortable with electrical and drain work. In double-bowl sinks, the disposal usually goes in the bowl that is used for food prep.

Drain position (center, rear-offset or side-offset) is listed on each spec sheet. An offset drain keeps plumbing out of the way and leaves more cabinet storage, while a center drain gives the most symmetrical look. Check it against your existing plumbing before ordering.

Most drain leaks come from the connection, not the sink. Check that the strainer flange is sealed with plumber's putty or the correct gasket, that the locknut under the sink is tight, and that the slip-nut washers on the tailpiece and trap are seated. If water appears around the rim, the countertop seal (silicone) may need to be redone. Call your installer first; if you believe a part is defective, send us photos.

A few drops or a thin film near the corners is normal. Larger puddles usually mean the sink was installed slightly out of level or the cabinet has settled, which can cancel out the Speedy Drain slope. Place a level across the rim front-to-back and side-to-side; if it is off, your installer can adjust the mounting. If the sink is level and water still pools, contact us with photos.

Avoid them. Many drain openers contain sulfuric or hydrochloric acid or concentrated lye, which can etch or discolor stainless steel and damage seals. Use a plunger, a drain snake or an enzyme-based cleaner. If a chemical product is ever used, rinse the sink and drain area immediately with plenty of water.

It depends on the pack. Max+ packs bring the sink plus 8 accessories: Sink Grid, All Metal Sink Strainer Basket And Lid, Sink Sponge And Brush Holder, Stainless Steel Colander, Premium Bamboo Cutting Board, Roll-Up Drying-Cooling Rack, Silicone Holder/Coaster Pad and Adjustable Clip-on Silicone Strainer. Oskan workstation models get the Workstation Stainless Steel Colander and the Roll-Up Drying-Cooling Rack Workstation instead. Type your part # at luvul.com/product-data to see the exact list for your box, and check it as soon as the sink arrives.

The grid lifts pots, pans and dishes off the bowl floor, which is the single best way to prevent scratches and dents in daily use. It also lets water drain under the dishes. Take it out once a week to clean underneath it.

Wash it with warm soapy water and a soft brush, rinse and dry. Check the rubber or silicone feet occasionally and replace them if they are worn, because bare metal feet can scratch the sink.

Yes. Replacement feet and bumpers are small parts we can send out. Send your model number and a photo of the grid.

We do not recommend rubber mats. They trap water and food residue against the steel, which can cause discoloration and spotting. Use the stainless grid instead, and never leave sponges or wet cloths in the sink overnight.

Rinse the sink after use, wipe it with a soft sponge and mild dish soap, rinse again, and dry it with a soft or microfiber towel. Drying is the step most people skip, and it is what prevents water spots and mineral film.

About once a week. Use a non-abrasive stainless steel cleaner or a gentle cleanser made for stainless (oxalic-acid cleansers such as Bar Keepers Friend-type products work well), applied with a soft sponge along the direction of the grain. Rinse thoroughly and towel-dry.

The satin finish has fine parallel lines. Wiping along those lines keeps the finish uniform and helps light scratches blend in; scrubbing in circles can leave visible swirl marks.

Avoid: steel wool and metal scrub pads; wire brushes; chlorine bleach and cleaners containing chlorides; hydrochloric (muriatic) acid, sulfuric acid and chemical drain openers; silver-dip and photo-developing chemicals; oven cleaners; and harsh scouring powders. If any of these contacts the sink, rinse it off immediately with plenty of water.

It is best to avoid it. Chlorine can pit and stain stainless steel, especially if it sits on the surface or dries there. If you must use diluted bleach for another task (for example, soaking something in a container), keep it off the sink, and if it splashes, rinse immediately and thoroughly.

Yes, diluted white vinegar (about 1 part vinegar to 3 parts water) is a good way to remove hard-water film. Wipe it on, let it sit a few minutes, rinse well and dry. Do not leave vinegar sitting on the surface for hours.

Oxygen-based (percarbonate) cleaners are generally gentle on stainless steel when dissolved in water and rinsed off afterward. Do not leave a concentrated paste or soak sitting in the sink for long periods, and always rinse and dry.

First remove any film with a stainless cleaner or diluted vinegar, rinse and dry. Then apply a few drops of mineral oil or a stainless steel polish to a soft cloth and buff along the grain. This evens out the appearance and helps water bead off.

Short soaks are fine. Avoid leaving cast iron pans, carbon-steel knives or wet steel cans in the sink for long periods; they shed iron particles that cause rust-colored spots on the stainless surface. Also avoid leaving foods high in salt or acid (pickles, tomato sauce, mayonnaise, mustard, citrus) on the steel for long periods.

LUVUL laundry sinks are made for washing, soaking and hand-rinsing. Rinse the sink well after using detergents, stain removers or pool/garden chemicals, and never leave bleach, chlorine or acid-based products sitting in the bowl. Paint, plaster and grout should be rinsed away before they dry.

Fine surface scratches are a normal part of using any stainless steel sink and are not a manufacturing defect. On a satin finish they blend into an even patina over the first months. Using the bottom grid and cleaning along the grain keeps them to a minimum. If you see a deep scratch when you unbox the sink, do not install it: photograph it and report it right away.

Light scratches can be softened by cleaning along the grain with a mild cleanser. For deeper scratches, a non-woven abrasive pad (fine grade) or a stainless scratch-repair kit used strictly in the direction of the grain can blend them. Test on a small, hidden area first, work gently and evenly over a larger area to avoid a visible patch, and never use steel wool. If you are unsure, contact us before trying.

Almost certainly not. These spots are typically iron particles from outside sources (cast iron cookware, steel wool, construction dust, metal filings, iron-rich water, a wet can) that oxidize on the surface. Remove them with an oxalic-acid cleanser (Bar Keepers Friend-type) on a soft sponge, rubbing along the grain; rinse and dry thoroughly. Then find and remove the source so the spots do not come back. If a spot will not come out after several gentle cleanings, send us close-up photos.

Those are mineral deposits (calcium and magnesium) left behind when hard water evaporates. Remove them with diluted white vinegar or a stainless cleaner, rinse and towel-dry. Drying the sink after use, and using a water softener if your water is very hard, prevents them from coming back.

Rainbow-colored tints are usually heat tint (from very high heat, for example a torch during plumbing work) or a thin film from starchy water, detergents or minerals. Films can usually be removed with a stainless cleaner or diluted vinegar. True heat tint is harder to remove; contact us with photos.

Make a paste of baking soda and water, apply it with a soft sponge along the grain, rinse and dry. For tougher marks, use an oxalic-acid stainless cleanser. Do not use scouring powders with chlorine.

Soften fresh paint or grout with warm soapy water and lift it with a plastic scraper or wooden stick. For adhesive or sticker residue, use a small amount of mineral spirits or a citrus-based adhesive remover, then wash with soapy water, rinse and dry. Never scrape with metal blades.

Those are usually metal transfer marks from aluminum or cast iron cookware, not scratches in the sink. They normally come off with an oxalic-acid cleanser or a stainless cleaner rubbed along the grain.

Pitting on 304 stainless is rare and is almost always caused by prolonged contact with chlorides (bleach, chlorine cleaners, salt water, some pool chemicals) or acids. Stop using the product responsible, rinse the sink well, and send us close-up photos along with a description of cleaning products used so we can assess it.

If you notice a dent when unboxing, do not install the sink: photograph it and report it right away. A dent that appears after installation usually comes from an impact (a dropped pot or a heavy object), and accidents are not covered by the warranty. Send us photos anyway and we will tell you what can be done.

Handmade sinks can show very slight surface undulation when viewed at a low angle under strong light; this is a normal characteristic of formed and welded steel. A bottom that visibly moves, pops or 'oil-cans' when pressed should be reported with a short video so we can evaluate it.

Common causes: mute pads damaged or removed during installation, the sink not fully supported so it vibrates, or a garbage disposal transmitting vibration. Check under the sink that the pads are intact and that the sink is firmly supported. If needed, add-on sound-dampening spray or pads can be applied to exposed underside areas. Contact us if the pads appear to be missing from the factory.

Stainless steel sinks do not leak through the metal. Water under the sink almost always comes from the drain connections, faucet or supply lines, the countertop seal, or condensation on cold pipes. Dry everything, then run water and look carefully with a flashlight to find the source. If you find moisture that seems to come from a weld seam, stop using the sink and contact us immediately with photos and a video.

This is an installation issue, typically failed silicone or loose mounting clips, often after heavy loads. Stop placing weight in the sink and contact your installer or fabricator to re-secure it, ideally with an added under-sink support. It is not a defect in the sink itself.

Before signing, check the box for crushed corners, punctures or other damage. If the box is visibly damaged, note it on the carrier's delivery receipt (for example, 'box damaged, subject to inspection') and take photos. Then open the box and inspect the sink right away, before the installation date.

Please report any shipping damage, missing items or wrong products as soon as possible after delivery. Reporting early helps get a replacement moving quickly.

Use the report form on this page and choose 'Shipping damage'. Then send: your order number, the model, photos of the outside of the box (all sides, including the shipping label), photos of the inner packaging, and clear photos of the damage on the sink (one wide shot and one close-up). Keep the box and packaging until the claim is closed, because the carrier may ask to inspect them.

If the damage is severe and obvious, note it on the delivery receipt and photograph it before the driver leaves.

Report it to LUVUL support with photos of the box and the sink. Contact LUVUL support at sinks@luvul.com or (888) 995-8885, Monday to Friday, 8 am to 5 pm Eastern Time.

Either way, you can open a case with LUVUL and we will help coordinate with the seller.

Use the tracking link in your shipping confirmation email. If you bought from a dealer or retailer, they can provide tracking.

First, check all packaging carefully, including under the cardboard inserts and inside the grid or strainer bags, since small parts are sometimes packed separately. If it is still missing, use the report form on this page with your order number, model and a photo of what you received.

Do not install it. Compare the model label on the sink and box with your order confirmation, take photos of both, and contact us through the report form on this page. We will arrange the correct product.

Submit a parts request with your model number, the part name, the quantity and a photo if possible.

The model number is on the carton label and on your order confirmation or invoice. Take a photo of the carton label before installation; it is often hard to find once the sink is mounted.

Every LUVUL stainless steel kitchen sink has a Limited Lifetime Warranty: the structure and finish are warranted to be free from defects in material and workmanship under normal use for the lifetime of the product, for the original owner. Accessories have a 1-year warranty under the same terms. Commercial use is covered for 1 year. Full terms at luvul.com/warranty.

The original purchaser, for personal household use of the sink in its original location, bought from an authorized LUVUL dealer. The warranty is not transferable to a later owner. Display, discontinued and clearance products, and products from unauthorized dealers or discount outlets, are not covered.

Negligence, misuse, abuse, improper installation, accidents, hard water or mineral deposits, corrosive materials, improper maintenance, alterations (such as drilled holes), and damage from abrasive cleaners (powders, bleach, ammonia, alcohol, chlorine) or abrasive pads, steel wool and wire brushes. Labor, removal and reinstallation, incidental or consequential damages, marine or outdoor installations and free gifts are also not covered. See luvul.com/warranty for the full list.

Use the report form on this page with your contact details, part #, where and when you bought it, the installation date and a description of the problem. We will reply by email; answer with your photos (a wide shot of the whole sink and close-ups of the issue) and your proof of purchase. A short video helps for drainage, noise or leaks.

A dated receipt, invoice or order confirmation that shows the LUVUL model and where you bought it. If you bought through a builder or contractor, their invoice works. Keep it with your registration.

Complete information on the first submission is the fastest path to a decision: the part # from the box label, proof of purchase, and photos of the whole sink and of the issue.

No. The warranty does not cover labor or the cost of removing and reinstalling the sink, or incidental and consequential damages. Please do not remove an installed sink before we have reviewed your claim.

Not unless we ask. Most claims are resolved from photos and video. If a return or inspection is needed, we will send instructions first. Do not ship anything back without them. Shipping of a warranted replacement is covered for the first year (charges may apply for Hawaii, Alaska and Puerto Rico; international shipping is not included).

If a repair or replacement is approved, LUVUL repairs the sink or replaces it with a product of equal value, at LUVUL's option. If your model is no longer made, that means the closest current model of equal value.
