Refinishing a bathtub is one of those projects that sounds intimidating but is actually pretty straightforward. I did mine last year when I couldn’t justify the cost of replacing a perfectly good tub that just looked tired.
When It Makes Sense
Reglazing works for tubs that are structurally sound but cosmetically damaged – stains, scratches, faded finish. If you’ve got rust holes or the enamel is flaking off in chunks, you’re probably past the point where refinishing helps.
New tub installation costs thousands once you factor in plumbing, tile work, and disposal. A DIY reglaze runs under $100 in materials. Even hiring a pro is usually $300-500. Math works in reglazing’s favor.
The Prep Work
This is where most DIY jobs fail. Skip the prep, and your new finish peels off in a month.
Clean the tub aggressively. I mean really clean it – not just soap scum but all the embedded grime. Use a non-residue cleaner. Let it dry completely.
Sand the entire surface. Start with coarse grit to remove the gloss, then smoother grit to eliminate scratches. The goal is a surface the new coating can grab onto. Wipe away all the dust.
The Actual Reglazing
Tape off everything – fixtures, tiles, floor. Use plastic sheeting to protect surfaces. The coatings are nasty if they get where they shouldn’t.
Ventilation matters. Open windows, run fans, wear a respirator. The fumes from reglazing products are serious.
Apply the coating with a brush for edges and a roller for flat surfaces. Work in thin, even coats. Better to do two thin coats than one thick one that drips.
The Waiting
This part kills people. You can’t use the tub for 24-48 hours while it dries, then another few days for full curing. Four or five days total before you can take a shower.
If you try to rush it, you’ll wreck the finish. Ask me how I know.
Realistic Expectations
A professional reglaze lasts 10-15 years. DIY varies – if you do the prep right, 5-10 years is reasonable. Either way, you’ve bought yourself time at a fraction of replacement cost.
