A professionally refinished bathtub can last 12–15 years. I’ve seen refinished tubs that are still in great condition after 15 years. I’ve also seen tubs that started peeling within a year.
The difference is almost never the refinishing job. It’s how the tub was treated after.
The rules for a refinished tub are different from a factory-original porcelain tub. The coating is tough, but it’s not indestructible. The things that shorten its life are specific and avoidable.
Here’s the complete list.
What to Use for Cleaning
BarKeepers Friend + a soft sponge. That’s it.
BarKeepers Friend uses oxalic acid as its active ingredient. It’s effective at cutting through soap scum and mineral deposits, and it’s gentle enough not to scratch or dull the refinished surface. Make a paste with water, apply with a soft cloth or sponge, and rinse completely.
For light maintenance cleaning, any mild dish soap and a soft cloth works fine. Save the BarKeepers Friend for soap scum buildup and periodic deeper cleaning.
The Do-Not List
This is the part that matters. Refinished tubs have specific vulnerabilities that factory tubs don’t. Know this list, share it with everyone in your household, and actually follow it.
No Abrasive Cleaners
Comet, Ajax, Bon Ami — anything with a grit to it will scratch a refinished surface. Even a product that seems only slightly abrasive will gradually dull and scratch the finish over time.
Once the surface is scratched, it’s visually damaged and more susceptible to staining. You can’t polish scratches out of a refinished surface the way you can sometimes polish original porcelain.
No Scrubbing Pads
Green Scotchbrite, SOS pads, Brillo — these will scratch the surface. Use only soft cloths, soft sponges, or a non-abrasive bath brush.
Magic Erasers are also too abrasive for refinished surfaces. They’re fine for regular porcelain but they’ll dull a refinished finish faster than you’d expect.
No Drain Cleaners
Drano, Liquid-Plumr, and other chemical drain openers are caustic. They will damage a refinished surface on contact. Pour a slug of Drano into a refinished tub and you’ll likely have a permanently damaged spot in the bottom around the drain.
If you have a slow drain, use a drain hair catcher to prevent the problem in the first place. For an existing clog, use a manual drain snake rather than chemical openers.
No Hair Dye Near the Tub
Hair dye stains a refinished surface permanently. This isn’t like a soap scum ring that you can scrub off — hair dye penetrates the coating. There’s no removing it.
If you dye your hair at home, do it in a way that keeps dye off the tub surface. Put old towels down on the ledge, be careful about drips, and rinse any contact areas immediately.
No Suction-Cup Bath Mats
This is the one that surprises people. Suction-cup bath mats are common and seem harmless, but they’re one of the most reliable ways to damage a refinished tub.
When the mat is in the tub, the suction cups create thousands of small points of adhesion to the surface. The mat gets walked on, the suction cups flex and pull. Over time, this peels the coating. When you pull the mat out to clean the tub, you’re often taking small pieces of finish with it — you just can’t see them.
Use a fabric bath mat inside the tub instead, or a mat without suction cups. Outside the tub, a standard fabric bath mat is fine.
No Heavy Bleach Cleaners
Regular bleach in concentration — bathroom sprays that are heavily bleach-based, undiluted bleach — dries out and degrades the refinished surface over time. It strips the slight sheen of the coating and accelerates wear.
A very diluted bleach solution occasionally is fine. Spraying full-strength bleach cleaner regularly will shorten the life of your finish noticeably.
No Soap Bars Left on the Ledge
Soap bars left sitting on a refinished surface will leave a permanent stain. The soap leaches chemicals into the coating over time and creates a discolored impression of wherever the soap was sitting.
Use a soap dish with drainage that keeps the soap elevated off the tub ledge, or switch to liquid soap.
Fix Chips Immediately
If the finish chips — from dropping something hard on it, or from impact — fix it right away.
Water getting under a chip is how small surface damage becomes big problems. Once water is under the coating, it migrates outward under the finish and you end up with a large peeling area from what started as a small chip.
For small chips, a porcelain repair kit applied carefully will seal the area. For larger damage, call a refinisher for a touch-up. A professional touch-up on a chip costs far less than a full re-refinishing job.
Fix Dripping Faucets
A dripping faucet creates a constant stream of water hitting the same spot on the tub surface. Over time, the constant contact and mineral deposits from the water speed up wear at that spot.
Drip + minerals + daily standing water = accelerated finish deterioration in one area. Fix leaky faucets promptly.
Wipe It Down After Each Use
Thirty seconds. It’s worth it.
Standing water left in a refinished tub for hours every day isn’t catastrophic, but it does accumulate mineral deposits and accelerates wear. A quick wipe-down after each use keeps the surface looking better longer.
Think of it as wiping down a granite countertop — it’s a minor habit that extends the life of the surface.
What to Put Outside the Tub
Use a fabric bath mat outside the tub on the bathroom floor. Fabric mats lie flat, dry quickly, and don’t damage anything.
Inside the tub: if you need traction, look for mats with PVC backing rather than suction cups — see best bathtub mat without suction cups. And if you want to actually enjoy the tub you just refinished, a good bathtub pillow is worth it — just make sure it’s the clip-on style, not suction cup.
How Long It Lasts with Good Care
With all of the above followed consistently:
- Professional refinish: 12–15 years, sometimes longer
- DIY refinish done properly: 5–10 years
Without care — especially with abrasive cleaners, drain cleaners, or suction-cup mats — you can shorten that by half or more.

Quick Reference Summary
| Do | Don’t |
|---|---|
| BarKeepers Friend + soft sponge | Comet, Ajax, abrasive cleaners |
| Mild dish soap for regular cleaning | Scrubbing pads, magic erasers |
| Fabric mat inside tub | Suction-cup bath mats |
| Fix chips immediately | Ignore chips and let water in |
| Fix dripping faucets | Leave a constant drip |
| Wipe down after use | Leave standing water daily |
| Non-silicone caulk | Drano, Liquid-Plumr |
| Soap dish with drainage | Hair dye near tub |
That’s the whole list. It’s not complicated. The refinished surface is tough — as long as you’re not hitting it with the specific things that damage it, it’ll last a long time.
