Cultured marble is an engineered surface material made from crushed marble dust (calcium carbonate) mixed with polyester resin. The mixture is poured into a mold and sealed with a non-porous gel coat finish. The result is a solid, seamless surface that replicates the look of natural marble but is lighter, non-porous, and available in over 44 colors and patterns. Also known as engineered marble, composite marble, or marble-look solid surface.

Cultured marble is composed of approximately 75% crushed marble dust (calcium carbonate) and 25% polyester resin, plus color pigments. A protective gel coat layer is applied first inside the mold, forming the non-porous finished surface. The marble dust and resin mixture is then poured in and cured as a single solid piece.

No. Natural marble is quarried stone that is porous and requires regular sealing to prevent staining. Cultured marble is an engineered composite that mimics the look of natural marble but is 100% non-porous, up to 40% lighter, and available in 44+ colors and patterns — including Carrara, Calacatta, and granite looks. Cultured marble also costs significantly less than natural stone.

Both are non-porous and require no sealing. Key differences: cultured marble is up to 40% lighter than quartz, costs less at volume, and can be cast with integral bowls (one-piece vanity top + sink). Quartz cannot be molded with integral bowls and requires a separate undermount or drop-in sink. Quartz has better scratch and heat resistance. For a detailed comparison, see our Cultured Marble vs. Quartz page.

Cultured marble eliminates grout lines entirely — the biggest maintenance issue with tile. Tile showers require periodic grout resealing and are prone to mold in grout joints. Cultured marble shower panels install as large seamless sheets (up to 60" × 96"), reducing installation time by 60–70% compared to individual tiles. Tile offers more pattern variety but cultured marble is the preferred choice for hotels and commercial projects where maintenance cost matters. See our full comparison.

With proper care, cultured marble surfaces last 20–30+ years. The gel coat surface is repairable — minor scratches and chips can be buffed or filled without replacing the entire piece. ARSTAR products carry a 5-year warranty on gel coat finish and structural integrity. Many ARSTAR installations in hotels and multifamily housing have been in service for 15+ years.

Modern cultured marble with a quality gel coat does not yellow under normal use. The non-porous surface resists staining from soap, cosmetics, and household chemicals. Avoid prolonged contact with hair dye, nail polish remover, acetone, or harsh solvents. If a stain does occur, most can be removed with a non-abrasive bathroom cleaner.

Cultured marble has moderate heat resistance. It can handle warm items like hair dryers and curling irons briefly, but prolonged direct contact with very hot objects (above 150°F / 65°C) can damage the gel coat. Always use a protective mat for hot styling tools. For kitchen applications where heat resistance is critical, quartz or granite may be more suitable.

Yes. The gel coat surface of cultured marble is repairable. Minor scratches can be buffed out with fine automotive polishing compound. Small chips can be filled with gel coat repair kits that match the original color. Deep cracks or large chips may require professional repair. This repairability is a significant advantage over quartz and natural stone, which are difficult to repair in place.

Cultured marble uses less energy to produce than quarrying and transporting natural stone. The manufacturing process generates minimal waste — scrap material can be recycled into new products. Cultured marble surfaces last 20+ years, reducing replacement frequency. The material is also lighter than natural stone, requiring less fuel for transportation.

ARSTAR offers 23 vanity top models across three collections: Classic Collection (Oval Bowl, Camila, with drop-in and undermount options), Contemporary Collection (Charlotte, Charlotte Wave, Charlotte Square, Contempo, Carolina, with backsplash variants), and Minimalist Collection (Capri, Catherine, Christine, Alexa). Browse all models on the Vanity Tops page.

An integral bowl (also called an integrated sink) means the bowl and countertop surface are cast as a single piece — no seams, no undermount clips, no silicone joints. This creates a seamless, hygienic surface that is easier to clean and eliminates the risk of water leaking between the bowl and countertop. Most ARSTAR vanity tops feature integral bowls.

Integral: Bowl and surface are one piece — seamless, no separate sink needed. Undermount: A separate sink is mounted below the countertop surface, attached from underneath. The countertop surface wraps over the bowl edge. Drop-in: A separate sink sits inside a cutout in the countertop, with the sink rim sitting on top of the surface. ARSTAR offers all three configurations.

Vanity top widths range from 19" to 73" depending on the model. Standard depths are 19" and 22". Common widths: 25", 31", 37", 43", 49", 61", and 73". Custom sizes are available for builders and OEM partners. The Vanity Tops catalog shows all available sizes for each model.

ARSTAR vanity tops are available in 19" and 22" depths. The 19" depth is ideal for compact bathrooms, powder rooms, and ADA-compliant installations. The 22" depth is the standard for full-size bathroom vanities. Not all models are available in both depths — check individual product pages for specifics.

It depends on the model. Some models include an integrated backsplash (e.g., Charlotte, Contempo, Carolina). Others are available in both backsplash and no-backsplash versions (e.g., Contempo vs. Contempo No Backsplash, Carolina vs. Carolina No Backsplash). The Minimalist Collection models generally have a flat edge without a raised backsplash.

Standard ARSTAR vanity tops come with pre-drilled faucet holes in standard 4" centerset or 8" widespread configurations, depending on the model. Custom faucet hole configurations — including single-hole and no-hole — are available for OEM and bulk orders. Check individual product specifications for default drilling.

ARSTAR offers oval (Classic Collection), rectangular (Contemporary Collection, including wave and square profiles), and minimalist flat-edge (Minimalist Collection) bowl shapes. The oval bowl is the most popular for residential applications, while rectangular bowls are preferred in contemporary and hospitality settings.

Clean daily with mild soap and water or a non-abrasive bathroom cleaner. Use a soft cloth or sponge — never steel wool or abrasive scrubbers. Avoid harsh chemicals like bleach, ammonia, or acetone. Wipe spills promptly. For hard water buildup, use a vinegar-water solution (50/50). The non-porous gel coat surface does not require sealing or waxing — ever.

Yes. ARSTAR vanity tops are IAPMO R&T certified to CSA B45.5/IAPMO Z124 standards. They carry UPC and SCC certifications for compliance with U.S. and Canadian plumbing codes. ARSTAR's manufacturing facility is ISO 9001:2015 certified for quality management.

A cultured marble shower panel is a large, seamless wall surface made from cultured marble — typically 60" wide × up to 96" tall. Unlike ceramic tile, shower panels have zero grout lines, creating a smooth, non-porous surface that resists mold and mildew. Panels install over standard drywall or existing tile, reducing installation time by 60–70% compared to traditional tile.

ARSTAR offers 6 panel patterns across 3 groups: Classic Brick — Brick 6×24 and Brick 12×24 (subway tile look). Premium Patterns — Textured Brick 12×24 and Chevron (V-pattern). Solid Marble Finishes — Solid (flat smooth surface) and Calacatta Gray Solid (marble-veined). All patterns are available in 12 shower colors. Browse the full catalog.

Grout is the #1 maintenance problem in tiled showers — it absorbs water, grows mold, stains, and requires periodic resealing. Cultured marble panels eliminate grout entirely. The non-porous gel coat surface requires only soap-and-water cleaning. For hotels, this translates to 70–80% lower bathroom maintenance costs compared to tiled showers.

A standard ARSTAR shower panel system consists of 3 pieces: one back wall panel and two side wall panels. The back wall is typically 60" wide, and each side wall panel is typically 32"–36" wide. Pieces join at inside corners with a smooth, sealed seam. The three-piece design allows for easy handling and installation.

In many cases, yes — cultured marble panels can be installed over existing tile using construction adhesive, provided the tile surface is clean, flat, and structurally sound. However, best practice is to install over clean, dry drywall or cement board. Consult with your installer to evaluate the specific condition of existing tile before overlay installation.

Standard shower wall panel side walls are 32"–36" wide and 60"–96" tall. Back walls are 48"–60" wide. ARSTAR offers custom panel dimensions for builders and hotel renovation projects. Contact ARSTAR sales for custom sizing and minimum order quantities.

Hotels choose cultured marble shower panels because: (1) zero grout lines eliminate the #1 maintenance expense, (2) one-day installation vs. 3–5 days for tile reduces room downtime, (3) consistent color matching across hundreds of rooms, (4) non-porous surface meets hygiene standards, and (5) panels are CSA B45.5 certified for code compliance. ARSTAR supplies panels for hotel renovation and new construction programs.

A cultured marble shower pan (also called a shower base or shower receptor) is the floor piece of a shower. It is a solid, one-piece unit cast from cultured marble with a non-porous gel coat finish and a built-in anti-slip texture on the floor surface. The pan includes a pre-formed drain hole and is designed to connect to standard shower drains.

ARSTAR offers 11 shower pan configurations across 4 size families: 36×36" (center drain), 36×48" (center drain), 32×60" (center, left, and right drain), and 30×60" (center, left, right, left trench, and right trench drain). The 30×60" is the most popular for residential and hotel applications. See all configurations on the Shower Pans page.

ARSTAR shower pans come in three drain configurations: Center drain — drain in the center of the pan (most common). Offset drain — drain positioned left or right of center. Trench drain — a linear slot drain along the left or right edge of the pan, providing a modern, barrier-free look. Trench drains are available on the 30×60" size.

Yes. Every ARSTAR shower pan features a factory-applied anti-slip texture on the floor surface. The texture is integral to the gel coat — it will not wear off with use. The anti-slip surface provides traction when wet while remaining comfortable underfoot and easy to clean.

ARSTAR shower pans are designed to support ADA-compliant installations. The 30×60" and 32×60" sizes with low threshold profiles are commonly specified for accessible bathrooms. However, full ADA compliance depends on the complete installation — including grab bars, seat placement, and threshold height — which is the responsibility of the builder/installer.

Clean with mild soap and warm water using a soft cloth or sponge. For the anti-slip textured areas, a soft-bristle brush helps remove soap buildup from the texture. Avoid abrasive scrubbers, steel wool, or harsh chemicals (bleach, ammonia). For hard water deposits, use a 50/50 vinegar-water solution. The non-porous surface does not require sealing.

Yes. ARSTAR shower pans are designed to work with any of the 6 ARSTAR shower panel patterns. The pans and panels are available in the same 12 shower colors, ensuring a perfect color match. The pan's back wall width (60") matches the standard panel back wall width for seamless integration.

A trench drain shower pan features a long, narrow linear drain along one side of the pan instead of a round center drain. Trench drains create a sleek, modern look and allow the shower floor to slope in only one direction (rather than to a center point). They also make the shower feel more open and are popular in contemporary bathroom design. ARSTAR offers left and right trench drain options on the 30×60" size.

A cultured marble lazy susan is a rotating tabletop tray made from the same cultured marble used in bathroom surfaces. It features a non-porous gel coat finish, smooth rotation on a concealed bearing, and is available in ARSTAR's standard color families. Cultured marble lazy susans are a premium alternative to wood, plastic, or ceramic turntables.

ARSTAR offers 3 lazy susan designs: Ara — a classic smooth round design, Crater — featuring a textured crater pattern on the surface, and Hexagonal — a six-sided geometric design. All three are available in multiple colors and feature a 15" diameter. Browse the Lazy Susan collection.

All ARSTAR lazy susan models have a 15" (38 cm) diameter and are approximately ¾" thick. The size is designed for standard dining tables and kitchen islands. The compact profile keeps a low center of gravity for stable rotation.

The gel coat surface of cultured marble is non-porous and does not absorb liquids or bacteria, making it hygienic for food presentation. However, cultured marble lazy susans are designed as serving pieces — place food on plates or in bowls rather than directly on the surface. Avoid cutting directly on the surface as this can scratch the gel coat.

Wipe with a damp cloth and mild soap. The non-porous gel coat surface resists staining and does not absorb odors or liquids. Dry with a soft cloth to prevent water spots. Do not use abrasive cleaners or scrubbers. For stubborn spots, a non-abrasive all-purpose cleaner works well.

Yes. The lazy susan line is available through ARSTAR's private label program with custom branding, proprietary colors, and tailored packaging. Minimum order quantities apply. Contact ARSTAR sales for private label pricing and lead times.

Minimum order quantities vary by product line and customer type. Standard distributor orders typically require pallet-quantity minimums. Private label and custom color programs have higher MOQs. Retail and builder programs have different MOQ structures. Contact ARSTAR sales for specific MOQ information for your business type.

Standard products in stock colors ship within 5–10 business days. Custom sizes and custom colors require 3–6 weeks depending on complexity and quantity. Large hotel or multifamily orders with phased delivery schedules are coordinated with a dedicated project manager. Contact sales for current lead time availability.

ARSTAR ships via full truckload (FTL) and less-than-truckload (LTL) carriers from Laredo, Texas. Products are palletized and shrink-wrapped for protection during transit. Vanity tops and shower panels are packed vertically with foam dividers. Freight costs are calculated by destination and volume — ARSTAR provides competitive freight rates for both domestic and Canada shipments.

Yes. ARSTAR offers tiered volume pricing for distributors, builders, hotel chains, and retail partners. Pricing tiers are based on annual volume commitments. Higher volumes unlock deeper discounts and priority production scheduling. Contact ARSTAR sales to discuss volume pricing for your program.

Cultured marble vanity tops install on standard bathroom vanity cabinets. Apply a bead of silicone adhesive along the top of the cabinet. Set the vanity top in place and press down evenly. Connect the drain assembly and faucet. The integral bowl design eliminates the need for a separate sink installation. Most vanity tops can be installed by one person in under 30 minutes.

Shower panels are installed using construction adhesive applied to clean, dry drywall or cement board. Start with the back wall panel, then install side panels. Seal all inside corners and edges with 100% silicone caulk. The 3-piece system (1 back wall + 2 side walls) installs in 2–4 hours — compared to 3–5 days for ceramic tile. No grout, no special tools required.

Set the shower pan on a level, mortar-bedded subfloor. Connect the drain assembly to the existing drain pipe. Apply silicone caulk around the perimeter where the pan meets the wall. Allow 24 hours for the mortar bed and silicone to cure before installing wall panels. A licensed plumber should connect the drain to ensure proper slope and code compliance.

Never use abrasive scrubbers (steel wool, Scotch-Brite green pads), harsh chemicals (bleach, ammonia, acetone, drain cleaners), or abrasive powdered cleaners. These can damage or dull the gel coat surface. Avoid leaving standing chemicals (hair dye, nail polish remover) on the surface for extended periods. Stick to mild soap and water or non-abrasive bathroom cleaners.

Yes. Minor surface scratches can be buffed out using fine automotive polishing compound applied with a soft cloth. Small chips can be filled with a gel coat repair kit matched to the original color. For deep scratches or large chips, a professional cultured marble repair specialist can restore the surface. This repairability is a key advantage over quartz and natural stone, which are much harder to repair in place.

No. The gel coat surface of cultured marble is 100% non-porous — it does not absorb water, stains, or bacteria. No sealing, waxing, or special treatments are ever required. This is a major maintenance advantage over natural stone (which requires annual sealing) and tile (which requires grout sealing).

For hard water mineral deposits, apply a 50/50 solution of white vinegar and water. Let it sit for 5–10 minutes, then wipe clean with a soft cloth. For stubborn deposits, use a non-abrasive calcium/lime remover designed for bathroom surfaces. Rinse thoroughly after treatment. Regular wiping after each use prevents hard water buildup.
