How bathtub refinishing is done

A well-prepped refinish on a sound cast iron or steel tub typically gives ten to fifteen years of normal use, and a poor one fails in under two. The difference is almost entirely in the etching and stripping steps, which are invisible in the finished result. How the surface is cleaned afterwards matters nearly as much as the original work.

Substantially, in a finished bathroom. Refinishing typically runs a few hundred dollars, where replacing a tub in an alcove means removing tile, potentially opening the wall, disposing of the old tub and reinstating the surround. Replacement makes sense if the tub is the wrong size, is structurally failed, or the wall behind it is already water damaged.

Most systems need 24 to 72 hours before water contact. The finish is dry to the touch long before it has cured hard, and using it early is one of the most common ways to ruin an otherwise good job. Ask for the specific number for the product being used rather than assuming a day is enough.

Yes, and it is common, but the substrate flexes in a way cast iron does not, so the coating has to tolerate that movement. Published ranges for fiberglass run wider, roughly $300 to $1,000, because condition varies more and repairs to soft or cracked areas are frequently needed first.

The coatings and strippers used are strong, and proper practice is forced-air ventilation, room containment, and a supplied-air or appropriate cartridge respirator for the applicator. Plan for the household, particularly anyone with asthma, and pets to be elsewhere during the work and for several hours after. A crew working without ventilation in a windowless bathroom is a real warning sign.

Yes, and doing both at once is usually better value than returning later, because the setup, masking and ventilation are already in place. Expect the surround to add roughly $400 to $600 to a tub-only price for a standard alcove, more if the tile runs to the ceiling or wraps a larger area.

Yes. White and biscuit are standard, and most shops will spray other colors for a modest premium. Going from a dark color to white can need an extra coat for full coverage. Bear in mind that a colored tub is harder to touch up or match later than a standard white one.

Use a non-abrasive liquid cleaner and a soft cloth or sponge. Avoid powdered cleansers, abrasive pads, bleach left to sit, and anything marketed as a heavy-duty bathroom scrub. Rinse and dry the tub floor after use where practical, because standing water at the drain is where failures tend to start.
