What is a cultured marble shower pan?

A cultured marble shower pan (also called a shower base) is a one-piece base cast from a polyester resin and marble dust composite, finished with a non-porous gel coat and an anti-slip textured floor surface. Unlike tile shower floors, cultured marble shower pans have zero grout lines and no seams where water can penetrate. ARSTAR offers 11 configurations across 5 sizes with 6 drain positions.

What sizes are available for ARSTAR cultured marble shower pans?

ARSTAR cultured marble shower pans are available in five standard sizes: 30x60, 32x60, 36x36, 36x48, and 36x60 inches. Drain position options include center, left, right, left trench, right trench, and corner. Custom sizes are available for hotel renovation and multifamily programs.

Are ARSTAR shower pans anti-slip?

Yes. Every ARSTAR cultured marble shower pan includes a factory-applied anti-slip textured floor surface as standard. The texture is molded into the gel coat during manufacturing — it will not wear off or degrade over time. This eliminates the need for aftermarket anti-slip mats or coatings.

How do you clean a cultured marble shower pan?

Cultured marble shower pans clean with mild soap and water or any non-abrasive bathroom cleaner. The non-porous gel coat surface resists soap scum and mineral buildup. Never use abrasive scrubbers, bleach, or ammonia-based cleaners. No sealing is ever required.

Can ARSTAR shower pans be custom sized?

Yes. ARSTAR manufactures shower pans to custom dimensions for hotel renovation programs, multifamily projects, and custom home applications. Custom drain positions are also available. Minimum orders apply for custom production. Quotes within 24 business hours.

Why do hotels choose cultured marble shower pans over tile?

Hotels choose cultured marble shower pans (shower bases) because they eliminate grout lines on the shower floor — the leading source of mold, staining, and maintenance labor. The built-in anti-slip surface meets safety requirements without aftermarket coatings. One-piece installation reduces room downtime during renovations. ARSTAR supplies color-matched pans and walls in 13 colors for consistent presentation across all guest rooms.

Why Cultured Marble

Cultured Marble Shower Pans vs.
Tile & Fiberglass Bases

A cultured marble shower pan — also known as a shower base — is a one-piece base cast from a polyester resin and marble dust composite, finished with a non-porous gel coat and a factory-applied anti-slip textured floor. Unlike tile shower floors, cultured marble pans have zero grout lines and no seams where water can penetrate — eliminating the primary source of mold, leaks, and maintenance.

ARSTAR shower pans feature a built-in anti-slip textured surface molded into the gel coat during manufacturing — it will not wear off or degrade. The non-porous surface wipes clean with soap and water, never requires sealing, and resists soap scum and mineral buildup.

One-piece construction means zero leak points — a critical advantage for multi-story hotels where tile shower floor leaks cause costly damage to rooms below. Installation runs significantly faster than tile, reducing room-out-of-service time during renovation. All backed by a 5-year manufacturer warranty and certified under CSA B45.5 / IAPMO Z124.
