How Bathtub Reglazing Works: The 6-Step Process Explained
A professional reglazing job follows the same six steps regardless of tub material or contractor. Understanding the process helps you evaluate quotes (a contractor who skips steps is cutting corners) and set realistic expectations for the day of the job.
A Note on Terminology
Reglazing, refinishing, and resurfacing all describe the same service. Technically, reglazing refers specifically to applying the final glaze or topcoat. Refinishing is the broader term for the entire strip-and-recoat process. Resurfacing is the most general term. In practice, contractors and homeowners use all three words interchangeably. If you search for any of these terms, you will find the same service. Do not be confused by a contractor who uses a different word than you expected.
Ventilation Setup
15 to 30 minutes
The contractor seals the bathroom doorway with plastic sheeting and sets up an exhaust fan ducted to a window or exterior vent. This creates negative pressure in the room, pulling chemical fumes out and drawing fresh air in through gaps. Proper ventilation is the single most important safety step. A contractor who skips this or simply says "we open the window" is cutting corners.
Chemical Cleaning and Stripping
45 to 60 minutes
The tub surface is cleaned with acid-based cleaners to remove soap scum, body oils, mineral deposits, and any previous coatings or patches. The old finish is chemically stripped to bare substrate. This step determines how well the new coating adheres. Rushing the chemical strip is the most common cause of premature peeling.
Sanding
30 to 45 minutes
The stripped surface is sanded to create a rough texture that provides mechanical adhesion for the primer and topcoat. Professional contractors use a combination of abrasive pads and orbital sanders. The goal is a uniformly rough surface with no glossy spots. This is the step that separates professional results from DIY: a pro sands every square inch thoroughly.
Chip and Crack Repair
15 to 30 minutes
Any chips, cracks, or divots are filled with two-part epoxy filler, then sanded flush with the surrounding surface. Minor chips (2 to 3 small ones) are typically included in the base price. Extensive damage with 5+ chips or larger cracks may add $50 to $150 to the job. The repair needs to be completely smooth because the topcoat will reveal any unevenness.
Bonding Primer
20 to 30 minutes
A bonding primer is sprayed or rolled onto the entire surface. The primer creates a chemical bond between the sanded substrate and the topcoat. Professional contractors use HVLP (high volume, low pressure) spray equipment for even coverage. The primer needs 15 to 20 minutes to tack up before the topcoat is applied.
Topcoat Spray Application
45 to 60 minutes
Two to three coats of the topcoat are sprayed using HVLP equipment. Each coat is thin and even. The contractor waits a few minutes between coats for flash-off time. The result is a smooth, glossy, factory-like finish. The topcoat is typically a two-part polyurethane or acrylic urethane that cures to a hard, durable shell.

What to Expect During the Job
There will be a strong chemical smell throughout the job. Even with proper ventilation and safer stripping chemicals, the odour is noticeable. Keep the bathroom door closed to the rest of the house. Open windows in adjacent rooms.
Pets and children should be in another part of the house or away from the home entirely during the job and for several hours after. The fumes are strongest during the stripping and priming stages.
The contractor will need access to electricity (for the exhaust fan and spray equipment) and water. They will tape and mask fixtures, walls, and the floor around the tub. Expect some cleanup work around the edges when they are done, though professional crews clean up after themselves.
After the Job
- 24 to 48 hours: Absolutely no water contact. Do not touch the surface. Do not place anything in the tub.
- 48 to 72 hours: The surface is touch-dry but still curing. Light use (a quick shower) is usually safe, but check with your contractor.
- First week: Avoid standing water in the tub. Quick showers only. No baths.
- 30 days: Full chemical cure. Normal use can resume, including baths. Begin the regular cleaning routine.
