Type of bathtub material.
Porcelain on steel (POS) or enameled steel | Resists acid, corrosion, abrasion. Flameproof, colorfast, sanitary, durable. If chipped, can rust. Can be noisy. |
POS composite | Lightweight, better heat retention. If chipped, can rust. |
Acrylic reinforced with fiberglass | Low cost, lightweight, repairable. Easy to clean. Keeps water warm. May scratch or discolor. Do not use abrasives. |
Fiberglass-reinforced plastic (FRP) | With gel coating. Low cost, lightweight, easy to install. Less durable than acrylic; quality varies. Do not use abrasive cleansers. |
Cast iron with enamel | Very durable. Keeps water warm. Extremely heavy. Difficult to repair. Sand-blasted non-skid bottom very difficult to clean. |
Cultured marble (limestone, resin, gelcoat) | Tough, durable. Can repair slight chips. Moderate cost. Surface may scratch. Very brittle, thermal shock can crack. |
Stone | Very heavy, requires structural support. Marble not recommended; very porous. |
Solid surfacing materials | Warm to touch, retain water temperature. More damage resistant, repairable than cast iron and acrylic. White exterior can be painted. |
Wood | Most woods will warp, crack, or rot. Teak will dry out and split if not used regularly. May not meet codes. Unique designs, expensive. |
Ceramic tile | Durable, great variety of patterns, shapes, sizes. Water-resistant grout. Requires skilled installation. Tile cleans well, grout may not. |
